Hereinafter, a first embodiment of the present invention will be described with reference to the accompanying drawings.

  The providing apparatus 100 according to the first embodiment of the present invention configures the providing system 1 of FIG. 1 that provides content to a user. The providing system 1 includes a communication network 10 and terminal devices 210 and 220, in addition to the providing device 100.

  The providing device 100 transmits, to the terminal device 210 or 220, a content used for selling a product or service related to travel (hereinafter, referred to as a product or the like) and a message determined to be important based on the content. . Accordingly, the providing device 100 provides the content and the message to the user of the terminal device 210 or 220.

  The communication network 10 is the Internet, and is connected to the providing device 100 and the terminal devices 210 and 220. The terminal devices 210 and 220 are smartphones carried by the user, and receive and display the content and the message transmitted from the providing device 100.

  The providing device 100 is configured by a server machine as shown in FIG. The providing device 100 includes a CPU (Central Processing Unit) 101, a ROM (Read Only Memory) 102, a RAM (Random Access Memory) 103, a hard disk 104, a communication circuit 105, a video card 106, a display device 107, and an input device 108. Prepare.

  The CPU 101 executes the program stored in the ROM 102 or the hard disk 104 to perform overall control of the providing apparatus 100. The RAM 103 temporarily stores data to be processed when the CPU 101 executes the program.

  The hard disk 104 stores various data and a table storing the data. Note that the providing device 100 may include a flash memory instead of the hard disk 104.

  The communication circuit 105 is a NIC (Network Interface Card), and performs data communication with terminal devices 210 and 220 connected via the communication network 10.

  The video card 106 renders an image based on the digital signal output from the CPU 101 and outputs an image signal representing the drawn image. The display device is an LCD (Liquid Crystal Display), and displays an image according to an image signal output from the video card 106. The providing apparatus 100 may include a PDP (Plasma Display Panel) or an EL (Electroluminescence) display instead of the LCD.

  The input device 108 is any one or more of a keyboard, a mouse, a touch pad, and a touch panel, and inputs a signal according to a user operation.

  The CPU 101 of the providing apparatus 100 executes the storage process of FIG. 3 that generates and stores a message addressed to the user of the terminal device 210 or 220 using the hardware of FIG. Thereby, the CPU 101 functions as the generation unit 110 of FIG. 4 that generates a message and the storage unit 120 that stores the generated message. In addition, the hard disk 104 functions as an information storage unit 190 that stores a message.

  The information storage unit 190 stores the message box table of FIG. 5 in which a plurality of messages are stored, and the message box table stores a plurality of records. Each record stores data in which a user ID (IDentification) for identifying a user who is a destination of a message is associated with a URL (Uniform Resource Locator) indicating the location of the message. Since the subject and body of the message are described on a web page as shown in FIG. 6, the URL of the web page on which the message is described is used as the URL of the message.

  The URL of the message further includes the subject and body of the message, a tag that is a keyword that describes the message, and whether the body has been displayed to the user (hereinafter referred to as read) or not (hereinafter referred to as unread). ) Is associated with the flag.

  In addition, the URL of the message includes a relevance indicating the degree of relevance between the message and the content (hereinafter referred to as “viewed content”) browsed by the user who is the destination of the message. The display order calculated based on the information is associated with the display order. This is because messages related to browsed content are more important to the user.

  Further, the information storage unit 190 stores a product table (not shown) that stores a plurality of records relating to products and the like. Each record of the product table stores data in which a product or the like related to travel, a current price of the product or the like, and a previous day's price are associated with each other.

  The CPU 101 in FIG. 2 starts execution of the storage process in FIG. 3 for storing the message in the message box table in FIG. 5 at a predetermined timing.

  When the storage processing is started, the generation unit 110 of FIG. 4 generates a message addressed to the user based on the action history of the user (Step S01), and then extracts a tag from the generated message (Step S02).

  As an example of the action history, the following description will be given taking that the user of the terminal device 210 has added a round-trip ticket to Mexico to the favorite list. The generation unit 110 executes the storage process at a predetermined cycle such as every day, for example, at a predetermined time such as 2:00 am. In the execution of this predetermined cycle, the generation unit 110 refers to the user's favorite list of the terminal device 210 and determines that the user is considering booking a round-trip air ticket in Mexico. Next, the generation unit 110 refers to a product table (not shown) to acquire the current price and the previous day's price associated with the round-trip ticket to Mexico. Thereafter, when determining that the current price of the ticket is lower than the previous day's price, the generation unit 110 generates a subject and a body of a message notifying the reduction of the round-trip ticket to Mexico to the user, and Generate a web page describing the subject and body.

  Thereafter, the generation unit 110 performs a morphological analysis of the subject and the body of the message notifying the price reduction of the round-trip air ticket of Mexico, and obtains the morphemes “Mexico”, “air ticket”, and “price reduction” obtained by a predetermined number or more. Tag.

  The message generated by the generation unit 110 includes, for example, a message notifying of a reduction in the price of a domestic hotel added to the favorites list. The generation unit 110 generates a web page in which this message is described, and extracts tags “domestic”, “hotel”, and “price reduction”.

  Furthermore, the generation unit 110 executes a storage process at the timing of the reception of the reservation, for example, generates a message notifying the reception of the reservation of the round-trip air ticket of the United States, and, for example, generates the message “USA”, “air ticket” , “Reservation”, and “accept” are extracted. Similarly, for example, the generation unit 110 generates a message for notifying the reservation cancellation of the round-trip air ticket in the United States, and extracts the tags “America”, “air ticket”, “reservation”, and “cancel”.

  Thereafter, the storage unit 120 associates the user ID of the user who is the destination of the message with the URL, subject, body, and tag of the web page on which the message is described, and the flag indicating that the message is unread. Generates data. Next, the storage unit 120 stores the generated data in the record of the message box table (step S03), and ends the execution of the storage processing.

  The user who is the destination of the message stored in the storage processing of FIG. 3 uses the terminal device 210 or 220 of FIG. For example, when trying to browse content used for searching for an air ticket, the user operates the terminal device 210 or 220 to cause the terminal device 210 or 220 to transmit a content request for provision of the content. . When the communication circuit 105 of the providing device 100 illustrated in FIG. 2 receives the content request, the CPU 101 starts executing the content providing process illustrated in FIG. Thereby, the CPU 101 functions as the authentication unit 130, the specifying unit 140, and the providing unit 150 as illustrated in FIG.

  The authentication unit 130 authenticates the user, and the specifying unit 140 specifies browsing content to be viewed by the user who has successfully authenticated. The providing unit 150 changes the display order of the messages stored in the message box table of FIG. 5 according to the specified content, and provides the user with the message or content whose display order has been changed.

  The information storage unit 190 of FIG. 4 stores a user authentication table (not shown) in which a plurality of records used for user authentication are stored. Each record of the user authentication table stores data in which a user ID for identifying a user is associated with a password of the user.

  Further, the information storage unit 190 stores the content table of FIG. 8 in which a plurality of records related to the content are stored. In each record of the content table, a URL of the content and a tag which is a keyword describing the content are stored in association with each other.

  The content tag is extracted from the content by the CPU 101 of FIG. 2 executing a tag extraction process (not shown) at a predetermined timing. The predetermined timing may be a predetermined period such as every day, for example, a timing when a predetermined time such as 1:00 am has arrived.

  In the tag extraction process, the CPU 101 acquires one unprocessed record from the content table of FIG. 8 and specifies the type of content based on the extension included in the URL stored in the acquired record.

  Next, when specifying that the type of the content is a still image or a moving image, the CPU 101 performs an OCR (Optical Character Recognition) process on the content itself of the still image or the still image of each frame constituting the moving image. Then, character information is extracted from the content. When the CPU 101 specifies that the content is a moving image or a sound, the CPU 101 performs character recognition processing on the moving image or the sound to extract character information. Further, when specifying that the content is a web page, the CPU 101 extracts character information from a source file described in a markup language and a still image content, a moving image content, or a music content referred to by the source file.

  Thereafter, the CPU 101 performs morphological analysis on the character information extracted from the content, and sets a predetermined number or more of the acquired morphemes as tags.

  As an example, the content is a web page used for searching for a round-trip ticket to Russia, China, Canada, or the United States as shown in FIG. 9, and the URL of the content is "./C001.html". Is described. In this case, the CPU 101 extracts character information from the source file of the content in “./C001.html” and performs morphological analysis on the extracted character information. As a result, the CPU 101 extracts the tags “air ticket”, “search”, “Russia”, “China”, “Canada”, and “USA”.

  After that, the CPU 101 stores the content URL “./C001.html” and the content tags “air ticket”, “search”, “Russia”, “China”, “Canada”, and “USA”. It is stored in the content table of FIG.

  Next, the CPU 101 repeats the above processing until there is no unprocessed record from the content table, and then ends the execution of the tag extraction processing.

  Hereinafter, for the sake of simplicity, an example will be described in which the terminal device 210 transmits a content request for providing the web page in FIG. 9 operated by the user identified by the user ID “U001”. The following is described. Therefore, the content request includes the URL “./C001.html” of the web page shown in FIG.

  When the execution of the content providing process of FIG. 7 is started, the authentication unit 130 of FIG. 4 outputs a message prompting for user authentication to the communication circuit 105 of FIG. The communication circuit 105 transmits the message to the terminal device 210.

  After receiving and displaying the message, the terminal device 210 inputs the user ID “U001” and the password according to the operation of the user who has visually recognized the message. Thereafter, the terminal device 210 returns the input user ID “U001” and the password to the providing device 100.

  After that, the authentication unit 130 acquires the user ID “U001” and the password received by the communication circuit 105 of FIG. 2, and performs user authentication based on the acquired user ID “U001” and the password (step S11).

  In step S11, the authentication unit 130 searches the user authentication table (not shown) for the password associated with the received user ID “U001”. Next, the authentication unit 130 determines that the user authentication has failed when the password cannot be retrieved or when the password obtained by the retrieval is different from the received password. After that, the authentication unit 130 outputs a message reporting that the user authentication has failed to the communication circuit 105 with the terminal device 210 as a destination, and then terminates the execution of the content providing process.

  On the other hand, if the password can be searched for and the password obtained by the search matches the received password, the authentication unit 130 determines that the user authentication has been successful. After that, the authentication unit 130 outputs a message reporting that the user authentication is successful to the communication circuit 105 with the terminal device 210 as a destination.

  After that, the specifying unit 140 in FIG. 4 acquires the content request from the communication circuit 105 in FIG. 2 (Step S12), and acquires the URL “./C001.html” included in the acquired content request. After that, the specifying unit 140 specifies the content at the acquired URL as the browse content to be browsed by the user of the terminal device 210 (Step S13).

  Next, the identification unit 140 searches the content table of FIG. 8 for a content tag associated with the URL “./C001.html”, and searches for “flight ticket”, “search”, “Russia”, “China”. "," Canada "and" USA ". This is because the browse content is the web page of FIG. 9 used to search for a flight ticket to Russia, China, Canada, or the United States.

  Next, the providing unit 150 determines, for each of the messages stored in the message box table of FIG. 5, how much the content is related to the message based on the tag of the searched content and the tag of the message. Is calculated (step S14).

  Here, the tags of the content searched in step S14 of FIG. 7 are “flight ticket”, “search”, “Russia”, “China”, “Canada”, and “USA”. On the other hand, there are three tags of the message "Mexico", "Airline ticket", and "Price reduction" that notify the price reduction of the round-trip ticket to Mexico stored in the message box table of FIG. For this reason, the providing unit 150 determines that one tag “air ticket” matches the content tag and the message tag, and reduces the number of matching tags “1” to the total number of content tags “6”. Is calculated as the relevance of the message.

  Further, the providing unit 150 determines that the tags of the message notifying the price reduction of the domestic hotel are “domestic”, “hotel”, and “price reduction”, and that the tag of the message does not match any of the content tags, and The relevance is calculated as “0.00”.

  Further, the providing unit 150 determines two tags “America” and “America” and “Receiving” in the tags “America”, “Flight Ticket”, “Reservation”, and “Receiving” of the message that notifies the reception of the reservation of the round-trip air ticket. It is determined that the “flight ticket” matches the content tag. Therefore, the providing unit 150 sets the value “0.33” obtained by dividing the number of matching tags “2” by the total number of content tags “6” as the relevance of the message. Similarly, the providing unit 150 calculates the relevance of the message notifying the cancellation of the reservation of the round-trip air ticket in the United States to “0.33”.

  After calculating the relevance in step S14, the providing unit 150 determines, for each of the messages stored in the message box table of FIG. 5, based on the relevance of the message and a flag indicating whether the message has been read or unread. Then, the importance of the message is calculated (step S15).

  The providing unit 150 determines in the message box table of FIG. 5 that the message notifying the price reduction of the round-trip ticket to Mexico is associated with a flag indicating unread. For this reason, the providing unit 150 adds the added value “1.00”, which is larger than the added value used for the read message, to the relevance “0.17” of the message, and calculates the importance as “1.17”. Usually, unread messages are more important to the user than read messages. Similarly, the providing unit 150 sets the importance to “1.00” by adding the additional value “1.00” to the relevance “0.00” of the unread message that notifies the reduction of the price of the domestic hotel.

  Here, the relevance of the message notifying the reservation of the round-trip air ticket to the United States and the relevance of the message notifying the cancellation of the reservation of the round-trip air ticket to the United States were both calculated to be "0.33". However, the providing unit 150 determines that the message notifying the reception of the reservation is associated with the flag indicating read, and the message notifying the cancellation of the reservation is associated with the flag indicating unread. For this reason, the providing unit 150 adds the additional value “0.00” to the relevance “0.33” of the message notifying the reservation acceptance, and adds the additional value “1.00” to the relevance “0.33” of the message notifying the reservation cancellation. Accordingly, the providing unit 150 calculates the importance of the unread message to be higher than the importance of the read message, even if the messages have the same relevance.

  After calculating the importance in step S15, the providing unit 150 changes the display order of each of the plurality of messages associated with the user ID “U001” of the user who browses the content in the message box table of FIG. Calculated based on The providing unit 150 sets the display order of the message indicating the cancellation of reservation of the most important US round-trip airline ticket to the highest order, "1", in order to make the display order higher as the importance is higher. Rank.

  After that, if the display order is not yet stored in the message box table, the providing unit 150 stores the calculated display order in association with the text or subject of the message. If the display order is already stored, the providing unit 150 changes the display order stored in the message box table to the calculated display order (step S16).

  After that, the providing unit 150 extracts a plurality of messages associated with the user ID “U001” based on the display order or importance (Step S17). The providing unit 150 may extract a plurality of messages that satisfy a predetermined condition that the display order is equal to or higher than a predetermined order, or may extract a plurality of messages that satisfy the predetermined condition that the importance is equal to or higher than a predetermined value. .

  Next, the providing unit 150 counts the number of unread messages among the plurality of extracted messages (step S18). Thereafter, the providing unit 150 edits the web page of FIG. 9 identified as the browsed content so that the object OB is displayed in the header portion of the content, and displays the counted number of unread messages in the object. Edit to be displayed on the OB. Further, when an operation of selecting the object OB (hereinafter, referred to as an object selection operation) is performed, the providing unit 150 displays the subject of the plurality of extracted messages in a balloon format as shown in FIG. Is further displayed on the web page after the editing to display the list in the descending order of the web page. Further, the providing unit 150 further edits the web page of FIG. 9 by linking to the web page of FIG. 6 in which the respective subject and the text are described in each of the subject names displayed in the list. .

  After that, the providing unit 150 outputs the edited web page, which is the content requested to be provided and in which the number of extracted unread messages is described in the object OB, to the communication circuit 105 to the terminal device 210 as a destination. (Step S19). After that, after the communication circuit 105 transmits the output web page to the terminal device 210, the providing unit 150 ends the execution of the content providing process.

  The terminal device 210 receives the web page, and displays a list of the subjects of the plurality of extracted messages according to an operation on the object OB by the user who has viewed the web page. Next, when an operation of selecting one of a plurality of subjects (hereinafter, referred to as a subject selection operation) is performed, the terminal device 210 transmits a web page on which a message is described based on a link provided to the selected subject. Specify the URL of the page. Thereafter, the terminal device 210 generates a message request for transmitting a web page including the specified URL and describing the message of the selected subject, and transmits the message request to the providing device 100.

  When the communication circuit 105 of the providing device 100 illustrated in FIG. 2 receives the message request, the CPU 101 of the providing device 100 starts executing the message providing process illustrated in FIG. When the message providing process is started, the providing unit 150 in FIG. 4 acquires a message request from the communication circuit 105 (Step S21). Next, the providing unit 150 extracts the URL included in the message request, and outputs a web page in which the message is described to the communication circuit 105 with the terminal device 210 as a destination (step S22).

  After that, the providing unit 150 changes the flag associated with the URL of the output web page to a flag indicating read in the message box table of FIG. 5 (step S23), and ends the execution of the message providing process. I do.

  The terminal device 210 that displays the content and the message transmitted from the providing device 100 is a smartphone as illustrated in FIG. The terminal device 210 includes a CPU 211, a ROM 212, a RAM 213, a flash memory 214, a data communication circuit 215a, an audio communication circuit 215b, a video card 216, a display device 217, an input device 218, a speaker 219a, and a microphone 219b.

  The CPU 211, the ROM 212, the RAM 213, the video card 216, and the display device 217 in FIG. 12 have the same configurations and functions as the CPU 101, the ROM 102, the RAM 103, the video card 106, and the display device 107 in FIG.

  The flash memory 214 is a semiconductor memory and stores various programs and data. The data communication circuit 215a performs data communication with the providing apparatus 100 by performing data communication using radio waves with a base station (not shown).

The input device 218 is a touch panel, and inputs a signal or information according to a user operation. The speaker 219a inputs a signal representing surrounding sound, and the microphone 219b outputs sound according to a signal output by the CPU 211.

  When the input device 218 of the terminal device 210 inputs a signal indicating the URL of the content requested to be provided by the user according to the operation of the user, the CPU 211 starts to execute the content providing process of FIG. I do.

  When the execution of the content provision processing is started, the CPU 211 acquires the URL of the content based on the signal input by the input device 218. Next, the CPU 211 outputs a content request including the obtained URL to the data communication circuit 215a with the providing device 100 as a destination (step S31). After that, the data communication circuit 215a transmits the content request to the providing device 100.

  Thereafter, when the data communication circuit 215a receives a message prompting the user to be authenticated from the providing device 100, the CPU 211 performs a user authentication process for receiving the user authentication (step S32). Thereafter, when the data communication circuit 215a receives a message reporting that the user authentication has failed, the CPU 211 ends the execution of the content provision processing. On the other hand, when the data communication circuit 215a receives a message reporting that the user authentication has succeeded, the CPU 211 continues to execute the content provision processing.

  Thereafter, when the data communication circuit 215a receives the content, the CPU 211 acquires the content from the data communication circuit 215a (step S33). Next, the CPU 211 displays the obtained content on the display device 217 (step S34), and ends the execution of the content providing process.

  Next, each time the input device 218 operated by the user inputs a signal, the CPU 211 of the terminal device 210 receives a provision of a message determined to be important based on the content in accordance with the operation of the user. The execution of the message provision processing is started.

  When the message provision process starts, the CPU 211 of the terminal device 210 determines whether an operation of selecting an object OB included in the displayed content (that is, an object selection operation) is performed based on a signal input by the input device 218. It is determined whether or not it is (step S41). When determining that the object selecting operation has been performed (Step S41; Yes), the CPU 211 displays a list of message subjects in a format shown in FIG. 10 (Step S42), and ends the execution of the message providing process.

  On the other hand, if the CPU 211 determines that the object selecting operation has not been performed (step S41; No), the CPU 211 selects the subject listed in step S42 based on the signal input by the input device 218 (step S42). That is, it is determined whether or not the subject selection operation has been performed (step S43). When determining that the subject selection operation has not been performed (step S43; No), the CPU 211 ends the execution of the message providing process.

  On the other hand, if the CPU 211 determines that the subject selection operation has been performed (step S43; Yes), the CPU 211 sends a message request for transmission of the message of the selected subject to the data communication circuit 215a with the providing device 100 as a destination. Output (Step S44).

  After transmitting the message request to the providing device 100, the data communication circuit 215a receives the web page from the providing device 100.

  After that, the CPU 211 acquires the web page of FIG. 6 in which the message of the selected subject is described from the data communication circuit 215a (step S45). Thereafter, as shown in FIG. 15, the CPU 211 controls the display device 217 so that the web page on which the message is posted is displayed as a pop-up before the web page on which the content is posted. As described above, the CPU 211 causes the display device 217 to display the message on the content that the user has requested to provide (step S46). Thereafter, the CPU 211 reduces the number of unread messages notified by the object OB displayed on the web page of FIG. 10 by one (step S47), and ends the execution of the message providing process.

  According to these configurations, the providing device 100 changes the display order of the messages stored in the message box table in FIG. 5 according to the browse content browsed by the user of the terminal device 210 or 220, and the display order changes. The changed message is transmitted to the terminal device 210 or 220. Here, since the content that the user is browsing usually includes content that is important to the user, a message corresponding to the content that the user is browsing includes the content that is important to the user. I have. For this reason, even when the number of messages that need to be displayed increases, the providing device 100 can suppress an increase in the possibility that the user of the terminal device 210 or 220 skips an important message.

<First Modification of First Embodiment>
In the first embodiment, the providing apparatus 100 has been described to edit the web page so as to list the subject in the format shown in FIG. 10, but the present invention is not limited to this. The providing device 100 may edit the web page so as to display a list of all or part of the body text instead of the subject. Part of the text displayed in the list may be a character string having a predetermined number of characters from the beginning of the text, or may be a character string representing a summary of the text. The providing apparatus 100 may use a conventional summarization technique of generating an abstract of a text using, for example, words and expressions that repeatedly appear in a sentence.

<Modification 2 of Embodiment 1>
In the first embodiment, it has been described that the providing apparatus 100 extracts the tag of the content and the tag of the message at a predetermined timing. However, the present invention is not limited to this, and the providing device 100 does not have to extract the tag of the content and the tag of the message in advance. For example, after the content is requested, the providing apparatus 100 may extract a keyword included in the requested content.

<Variation 3 of Embodiment 1>
In the first embodiment, the providing unit 150 of the providing apparatus 100 determines, as the degree of association, the number of tags matching the content tag among the message tags with respect to the total number of “content” tags viewed by the user. It was explained that the ratio was calculated. However, the present invention is not limited to this. The providing apparatus 100 calculates the ratio of the number of tags that match the browsed content tag among the message tags to the total number of “message” tags as the degree of association. You may.

<Modification 4 of Embodiment 1>
In the first embodiment, the providing apparatus 100 determines the number of tags “identical” to at least one of the plurality of tags of the browse content among the plurality of tags of the message in step S14 of FIG. It has been described that the value divided by is the relevance of the message.

  However, the present invention is not limited to this, and the providing apparatus 100 determines the number of tags “identical” or “similar” to at least one of the plurality of tags of the browsed content among the plurality of tags of the message. A value obtained by dividing the total number of tags may be used as the relevance of the message. In order to determine whether or not two tags are similar, the providing device 100 according to the present modification stores, for example, data in which a certain keyword is associated with another keyword similar to the certain keyword. A similarity definition table having a plurality of records obtained is stored. The two keywords that are similar to each other include, for example, a keyword that represents the same meaning and content, a keyword that conceptually has a higher-order relationship, and a keyword that represents the meaning that is associated with each other.

<Variation 5 of Embodiment 1>
In the first embodiment, it has been described that the providing apparatus 100 performs the morphological analysis on the character information extracted from the content, and sets the morphemes acquired in a predetermined number or more as the tags.

  However, the present invention is not limited to these, and the providing device 100 may use not only a predetermined number or more of morphemes obtained from the content but also meta tags used for searching for the content as tags describing the content. Since the meta tag of the content is given by the content publishing entity or the like as a tag for explaining the content of the content, it is usually for explaining the content of the content more accurately than the morpheme.

  Hereinafter, for simplicity of description, a case will be described as an example in which there are two messages having the same relevance calculated based on only the morphological tag described in the first embodiment. The providing unit 150 of the providing apparatus 100 according to the present modification determines whether or not a priority tag, which is a meta tag, is set in advance to the browse content specified in step S13 of FIG. When determining that the priority tag is set in advance, the providing unit 150 includes the priority word which is the word described in the priority tag, or the one associated with the priority tag in the message box table of FIG. Is calculated to a value higher than the relevance of the non-priority message, which is the other message that does not include the priority word and is not associated with the priority tag.

  The providing unit 150 adds, for example, a predetermined addition value to the relevance of the priority message described in the first embodiment in order to calculate the relevance of the priority message to a value higher than the relevance of the non-priority message. I do. As an example, it is assumed that the message notifying the acceptance of the reservation of the round-trip air ticket in the United States stored in the message box table of FIG. Will be explained. In this case, the providing unit 150 calculates the relevance of the non-priority message as, for example, a value “0.33” obtained by adding a predetermined addition value “0.00” to the relevance “0.33” of the first embodiment. On the other hand, the providing unit 150 adds the predetermined message addition value “1.00”, which is larger than the addition value “0.00” of the non-priority message, to the message priority “0.33” of the first embodiment. The calculated value is “1.33”.

  In addition, the providing unit 150 may use a larger value as the predetermined addition value as the number of priority tags associated with the priority message or the number of priority words described in the priority message increases. For example, if the number of priority tags associated with the priority message or the number of priority words described in the priority message is “2”, the providing unit 150 sets, for example, the basic addition value “1.00” to the priority tag or the priority tag. A value “2.00” multiplied by the number of words “2” may be used as a predetermined addition value.

  The providing unit 150 calculates the importance based on the relevance, and changes the display order to be higher for a message having a higher importance. For this reason, the providing unit 150 calculates the relevance of the priority message higher than the relevance of the non-priority message, and changes the display order of the priority message to a priority that is higher than the display priority of the non-priority message.

<Modification 6 of Embodiment 1>
In accordance with the operation on the input device 108 in FIG. 2 by the administrator or the operator of the providing system 1, the providing apparatus 100 may add a subordinate tag in which an inappropriate word such as a synonym of a preferred word is described as a description of the content. May be provided.

  If a subordination tag is set in advance to the browse content specified in step S13 in FIG. 7, the providing device 100 includes the subordination word that is the word described in the subordination tag, or the message box table in FIG. Calculates the relevance of the subordinate message that is the message associated with the subordinate tag to a value lower than the relevance of the non-subordinate message that does not include the subordinate word and is not associated with the subordinate tag You may.

<Variation 7 of Embodiment 1>
In the first embodiment, the providing apparatus 100 is described to provide content in which a product or the like related to travel is described or a message related to the product or the like. However, the present invention is not limited to this. The content and the message provided by the providing device 100 may have any content and may be unrelated to the product or service.

<Eighth Modification of First Embodiment>
In the first embodiment, it has been described that the providing device 100 extracts a message whose display order or importance satisfies a predetermined condition from among messages addressed to the user using the terminal device 210 or 220 that transmitted the content request. However, the present invention is not limited to this, and the providing apparatus 100 may extract a message that satisfies a predetermined condition that the degree of association is equal to or more than a predetermined value. Further, the providing apparatus 100 may extract only a read message whose relevance satisfies a predetermined condition, only an unread message, or both an unread message and a read message. Further, the providing device 100 may extract a message addressed to all users of the providing system 1 or a message for which no address is specified. The message stored, extracted, and transmitted by the providing apparatus 100 may be a general electronic mail.

<Modification 9 of Embodiment 1>
In the first embodiment, it has been described that the providing apparatus 100 provides, for a plurality of messages whose display order or importance satisfies a predetermined condition, content that is edited so as to list the respective subjects at once, but is not limited thereto. Not necessarily.

  For example, when extracting “150” messages whose display order is from “1” to “150”, the providing unit 150 displays the subject of the “150” messages in three parts. The edited content may be provided. The display divided into three times is, for example, a list display of message subjects from display ranks "1" to "50", and a list of message subjects from display ranks "51" to "100" It may be a display and a list display of the subject of the messages whose display order is from “101” to “150”.

  For the display divided into three times, the providing unit 150 according to the present modification classifies, for example, messages whose display order is from “1” to “50” into a first group, and the display order is “51”. The messages from the "" position to the "100" position are classified into a second group, and the messages with the display order from the "101" position to the "150" position are classified into a third group.

  In order to display a list of the subject names of the first group, the providing unit 150 displays the number of unread messages in which the object OB is classified into the first group and performs an object selection operation in step S19 of FIG. In this case, the contents of FIG. 9 are edited so that the subject names of “50” messages belonging to the first group are displayed in a list.

  Further, after executing step S23 in FIG. 11, the providing unit 150 counts the number of unread messages classified into the first group, and determines whether the number of unread messages is “0”. When the providing unit 150 determines that the number of unread messages has become “0”, it stores the number of unread messages classified into the second group and the subject of “50” messages classified into the second group. Is output to the communication circuit 105 with the terminal device 210 or 220 as a destination. Upon receiving the number and the list, the terminal device 210 or 220 updates the number displayed on the object OB in FIG. 10 with the received number, and updates the subject displayed on the list to the subject included in the received list. .

  Similarly, when the providing unit 150 determines that the number of unread messages in the second group has become “0” after performing step S23 in FIG. 11, the providing unit 150 determines the number of unread messages in the third group and the number of unread messages in the third group. Outputs a list with the subject of the message saved.

  Note that the providing unit 150 classifies “150” messages from the first group to the third group. If a group in which unread messages are not classified is generated, the unread messages are not classified. For the group, the subject list display may be omitted.

<Tenth Modification of First Embodiment>
In the first embodiment, when the same degree of relevance is calculated between a certain unread message and a read message in step S15 of FIG. 7, the providing apparatus 100 determines the importance and display order of the unread message and the read message. Has been described as higher than the importance and the display order. However, it is not limited to this.

  When the same degree of relevance is calculated for the notification message that is a message that notifies the delivery status of the product or the provision date and time of the service, and the non-notification message that does not report both the delivery status and the provision date and time, the providing device 100 determines that the delivery When the content used for checking the status or the provided date and time is specified as the content to be browsed by the user, the importance and the display order of the notification message may be higher than the importance and the display order of the non-notification message. .

  For this reason, the information storage unit 190 of the providing apparatus 100 according to the present modification stores the URL of the confirmation content used for confirming the delivery status of the product or the like or the provision date and time in the content table of FIG. The delivery status or the name of the product or the like for which the provision date and time are confirmed are stored in advance in association with each other.

  In step S13 of FIG. 7, the specifying unit 140 of the providing apparatus 100 according to the present modification stores the information in association with the URL of the content to determine whether the specified browsing content is the content for confirmation. The unit 190 searches for the name of a product or the like stored. This is because the information storage unit 190 stores the name of a product or the like whose delivery status or provided date and time is to be confirmed in association with the URL of the content for confirmation.

  If the name of a product or the like can be acquired by a search, the identification unit 140 determines that the browsed content is the content for confirmation. If the name of the product or the like cannot be acquired, the identification unit 140 determines that the browsed content is not the content for confirmation.

  When the providing unit 150 of the providing apparatus 100 according to the present modification determines that the browsed content is the content for confirmation, the providing unit 150 determines whether the message whose importance is to be calculated is a notification message, for example, as shown in FIG. Is determined based on one or a plurality of tags associated with the message in the message box table. For example, when both the tag “delivery status” or “provision date and time” and the tag “confirmation” are associated with a message, the providing unit 150 determines that the message is a notification message. .

  Next, when the providing unit 150 determines that the message whose importance is to be calculated is a notification message, the product or the like whose delivery status or provision date and time is notified by the notification message is set to one or more items associated with the notification message. Identify based on multiple tags. The providing unit 150 specifies, for example, a tag representing a name of a product or the like stored in the information storage unit 190 from among one or a plurality of tags associated with the notification message, and a product having a name represented by the tag. And the like are identified as a product or the like for which the delivery status or the provision date and time is notified by the notification message.

  After that, the providing unit 150 determines whether the name of the product or the like whose delivery status or provision date and time is notified by the notification message matches the name of the product or the like whose delivery status or provision date and time is confirmed in the browsed content. Is determined.

  If the providing unit 150 determines that the names of the products and the like do not match, determines that the message whose importance is to be calculated is not a notification message, and determines that the browsed content is not the confirmation content, By adding an additional value, for example, a value “0.00”, which is smaller than the additional value used when it is determined that the name of the product or the like matches, to the relevance calculated in step S14, the importance is determined. calculate.

  On the other hand, when the providing unit 150 determines that the names of the products and the like match, the providing unit 150 is greater than the added value “0.00” used when the names of the products and the like do not match, when the relevance is determined. For example, the importance is calculated by adding the added value of the value “1.00”.

  Thereafter, in step S16 of FIG. 7, the providing unit 150 changes the display order to be higher for a message calculated to have a higher importance.

  According to these configurations, the providing device 100 according to the present modification can be configured such that, when the user is browsing the content used for confirming the delivery status of the product or the like or the delivery date / time, the delivery status or the delivery date / time of the product or the like. Is changed to the priority display order of the notification message that informs the user. For this reason, even if the number of messages that need to be displayed increases, it is possible to suppress an increase in the possibility of skipping a notification message that is important for the user who checks the delivery status or the provision date and time.

<Eleventh Modification of First Embodiment>
The terminal devices 210 and 220 have been described as being smartphones, but are not limited thereto, and may be, for example, desktop, notebook, or tablet personal computers.

<Example 2>
The terminal 210 or 220 according to the present embodiment reports the content being viewed by the user to the providing device 100, and the providing device 100 changes the display order of the message according to the reported content, and changes the display order. Provide the modified message to the terminal 210 or 220. Hereinafter, the same configuration as that of the first embodiment will be described using the same reference numerals as those used in the first embodiment, but differences between the present embodiment and the first embodiment will mainly be described.

  As shown in FIG. 16, the providing system 1 according to the present embodiment includes the communication network 10, the providing device 100, and the terminal devices 210 and 220 described in the first embodiment. The providing device 100 and the terminal devices 210 and 220 according to the present embodiment are communicably connected to an external server 900 installed outside the providing system 1 via the communication network 10.

  The external server 900 includes a CPU, a ROM, a RAM, a hard disk, and a communication circuit (not shown) having the same configurations and functions as the CPU 101, the ROM 102, the RAM 103, the hard disk 104, and the communication circuit 105 in FIG. The external server 900 stores the content used for selling the product or the like on the hard disk, and upon receiving a content request from the terminal device 210 or 220 by a communication circuit, returns the content to the terminal device 210 or 220 in response to the content request. I do.

  When the user of the terminal device 210 operates the input device 218 of the terminal device 210 shown in FIG. 12 to browse the content provided by the external server 900, the input device 218 inputs a signal corresponding to the operation. When a signal corresponding to the operation is input, the CPU 211 of the terminal device 210 starts executing a content providing process as shown in FIG.

  When the execution of the content provision processing is started, the CPU 211 of the terminal device 210 activates a web browser as shown in FIG. 18 and executes a plug-in program added to the web browser. Thereby, the object OB used for confirming the message is arranged in the toolbar area TB set in the screen of the web browser.

  Next, the CPU 211 of the terminal device 210 executes the same processing as steps S31, S33, and S34 in FIG. 13 (steps S51 to S53). Accordingly, the CPU 211 of the terminal device 210 outputs a content request to the external server 900 as a destination, and then acquires the content from the external server 900. Further, the CPU 211 displays the URL of the acquired content on the address bar AB arranged in the toolbar area TB in FIG. 18 and displays the content in the content area AC set in the screen of the web browser. The CPU 211 does not execute the user authentication process (step S32) in FIG. 13 because the external server 900 responds to the content request without requesting user authentication.

  Next, the CPU 211 of the terminal device 210 executes a plug-in program for reporting the displayed content to the providing device 100 in order to receive a message related to the displayed content. Is performed (step S54), the execution of the content provision processing ends.

  When the plug-in program execution process is started, the CPU 211 executes a process similar to step S32 in FIG. 13 to execute a user authentication process for receiving user authentication by the providing device 100 (step S61).

  Thereafter, the CPU 211 obtains the URL of the content displayed in the content area AC from, for example, the address bar AB, and transmits a report of the content being displayed including the obtained URL to the providing apparatus 100 as a data communication destination. The output is output to the circuit 215a (step S62).

  After transmitting the output report to the providing device 100, the data communication circuit 215a of the terminal device 210 stores the list in which the subject of the message extracted based on the reported content is stored and the number of the unread messages extracted Are received from the providing apparatus 100. Thereafter, the CPU 211 of the terminal device 210 acquires the list and the number of cases from the data communication circuit 215a (Step S63).

  Thereafter, the CPU 211 of the terminal device 210 controls the display device 217 to display the number of unread messages on the object OB in the toolbar area TB as shown in FIG. 18 (step S64), and then executes the plug-in program execution process. To end.

  When the communication circuit 105 of the providing apparatus 100 shown in FIG. 2 receives the report output in step S62 of FIG. 19 from the terminal device 210, the CPU 101 of the providing apparatus 100 responds to the report as shown in FIG. Starts execution of report response processing.

  When the report response process is started, a user authentication process similar to step S11 in FIG. 7 is executed (step S71).

  Next, the specifying unit 140 in FIG. 4 obtains a report from the communication circuit 105 (Step S72), and specifies the content at the URL included in the obtained report as the browse content to be browsed by the user of the terminal device 210. (Step S73).

  Thereafter, by performing the same processing as steps S14 to S18 in FIG. 7 (steps S74 to S78), a plurality of messages are extracted based on the reported content, and unread messages among the plurality of extracted messages are extracted. The number of messages is counted.

  Next, the providing unit 150 of FIG. 4 generates a list in which the subject of the plurality of extracted messages is stored, and stores the generated list and the counted number of unread messages with the terminal device 210 as a destination. Is output to the communication circuit 105 (step S79). After that, the providing unit 150 ends the execution of the report response process after the communication circuit 105 transmits the list and the number of unread messages to the terminal device 210.

  When the input device 218 of the terminal device 210 inputs a signal in accordance with the operation of the user who has visually checked the number of unread messages displayed on the screen of the terminal device 210, the CPU 211 executes the message provision process shown in FIG. Accordingly, after transmitting the message request to the providing device 100, the terminal device 210 displays the message received from the providing device 100.

  When the communication circuit 105 of the providing device 100 illustrated in FIG. 2 receives the message request, the CPU 101 of the providing device 100 executes the message providing process illustrated in FIG. Thereby, the providing device 100 returns a message in response to the message request.

  According to these configurations, the terminal device 210 or 220 outputs the report of the content displayed in the content area AC in FIG. 18 in step S62 in FIG. 19, and the specifying unit 140 of the providing device 100 The specified content is identified as the browsed content. Therefore, even if the content displayed in the content area AC is not the content provided by the providing device 100, the providing device 100 can specify the browsed content.

<Example 3>
The providing apparatus 100 according to the first embodiment determines the degree of association between the “1” content identified as the viewing content and the message in step S13 in FIG. (Called degree).

  However, the providing apparatus 100 according to the present exemplary embodiment can determine the degree of association between the message and the “plurality” of browsed content identified as the content browsed by the user at the “plurality” (see FIG. Hereinafter, a plurality of degrees of association are calculated. Hereinafter, the same configuration as that of the first embodiment will be described using the same reference numerals as those used in the first embodiment, but differences between the present embodiment and the first embodiment will mainly be described.

  In order to store a plurality of browse contents, the information storage unit 190 of the providing apparatus 100 according to the present embodiment stores a browse history table as shown in FIG. The browsing history table stores a plurality of pieces of data in which the user ID of the user, the URL of the specified browsing content, and the specific date and time of the content are associated.

  The providing apparatus 100 according to the present embodiment calculates a plurality of relevance using the browsing history table of FIG. 21 and provides a content for notifying the number of messages extracted based on the plurality of relevance, as shown in FIG. Such a content providing process is executed.

  When the providing apparatus 100 starts executing the content providing processing, the providing apparatus 100 executes the same processing as steps S11 to S13 of FIG. 7 described in the first embodiment (steps S81 to S83). Thereby, after authenticating the user using the terminal device 210 or 220, the providing device 100 acquires a content request from the terminal device 210 or 220, and specifies the content specified by the content request as the browse content.

  After that, the specifying unit 140 of the providing apparatus 100 obtains the system date and time from, for example, an OS (Operating System), and sets the obtained system date and time as the specific date and time of the content. Next, the specifying unit 140 generates data in which the user ID of the user authenticated in step S81, the URL of the browse content specified in step S83, and the specific date and time of the content are associated with each other. The obtained data is stored in the browsing history table of FIG. 21 (step S84).

  After that, the providing unit 150 of the providing apparatus 100 acquires a predetermined number of URLs of the browsed content associated with the user ID of the authenticated user from the browse history table in ascending order of the specific date and time associated with the URL. (Step S85). This is for specifying the browsed content specified from the previous time to the current time.

  Next, the providing unit 150 calculates, for each of the plurality of messages stored in the message box table of FIG. 5, a plurality of degrees of association with a plurality of contents at the plurality of URLs acquired in step S85. A multiple relevance calculation process as shown in FIG. 23 is executed (step S86).

  When the multiple relevance calculation process is started, the providing unit 150 specifies a plurality of messages associated with the user ID of the authenticated user from the message box table in FIG. This is for specifying a message addressed to the authenticated user.

  Next, the providing unit 150 determines whether or not there is an unattentioned message among the specified messages (step S101). When the providing unit 150 determines that there is an unattention message (Step S101; Yes), the provision unit 150 focuses on one of the unattention messages and sets it as the attention message (Step S102).

  After that, the providing unit 150 initializes the multiple relevance of the message of interest to a value “0.00” (Step S103).

  Next, the providing unit 150 determines whether or not there is an unfocused browse content among the predetermined number of browse contents respectively existing in the predetermined URL acquired in step S85 in FIG. 22 (step S104). ). When the providing unit 150 determines that there is an unobserved browse content (step S104; Yes), the providing unit 150 focuses on one of the unobserved browse contents and sets it as the attention browse content (step S105).

  Next, the providing unit 150 searches for the tag of the content of interest to be viewed and the tag of the message of interest from the content table of FIG. 8 and the message box table of FIG. 5, respectively, and performs the method described in the first embodiment. Is used to calculate the singular relevance (step S106).

  After that, the providing unit 150 calculates the elapsed time from the specific date and time of the noticed browse content to the system date and time (Step S107). After that, the providing unit 150 calculates a weighting coefficient that becomes smaller as the elapsed time becomes longer, such as a reciprocal of the elapsed time (step S108). This is because the content described in the browsed content often becomes less important to the user as time elapses from the date and time when the focused browsed content is browsed.

  Next, the providing unit 150 weights the singular relevance calculated in step S106 using the calculated weighting coefficient, and adds the weighted relevance to the plurality of relevance of the message of interest (step S109). ). After that, the providing unit 150 returns to Step S104 and repeats the above processing.

  In step S104, when the providing unit 150 determines that there is no unobserved browse content (step S104; No), the process returns to step S101 and repeats the above processing.

  In step S101, when the providing unit 150 determines that there is no unattention message (step S101; No), the providing unit 150 ends the execution of the multiple relevance calculating process.

  After executing the multiple relevance calculation process in step S86 in FIG. 22, the providing unit 150 has described the first embodiment based on the multiple relevance for each of the multiple messages stored in the message box table in FIG. The importance is calculated by the method (step S87). After that, the providing unit 150 performs the same processing as Steps S16 to S19 in FIG. 7 (Steps S88 to S91). Accordingly, the providing device 100 changes the display order of the messages based on the importance, extracts the message based on the display order, and sends the content in which the number of the extracted messages is described to the terminal device 210 or 220. Send. After that, the providing unit 150 ends the execution of the content providing process.

  According to these configurations, a plurality of degrees of association between a message and a predetermined number of contents browsed by a user in the past are calculated, and the display order of the message is changed based on the calculated plurality of degrees of association. Normally, since the contents viewed by the user in the past include matters important to the user, the display order is determined based on the singular degree of association between the message and one content recently viewed by the user. The display order of messages important to the user can be changed more accurately than one.

<Modification 1 of Embodiment 3>
In the third embodiment, it has been described that the providing unit 150 of the providing apparatus 100 calculates the importance based on whether the message is read or unread.

  However, the present invention is not limited to this. For example, the providing unit 150 determines the importance of a message (hereinafter, referred to as a privilege notification message) that informs about a privilege such as a product, such as a coupon, by transmitting the privilege notification message. The calculation may be based on the date and time when the original content was viewed.

  For this reason, the providing unit 150 according to the present modification executes an importance calculation process as shown in FIG. 24 instead of step S87 of the content providing process shown in FIG.

  When the importance calculation process is started, the providing unit 150 specifies one or a plurality of messages associated with the user ID of the user authenticated in step S81 in FIG. 22 in the message box table in FIG. This is for specifying one or a plurality of messages addressed to the authenticated user.

  Next, the providing unit 150 determines whether or not an unattentioned message exists in the specified one or a plurality of messages (step S111). If the providing unit 150 determines that there is an unattention message (step S111; Yes), the provision unit 150 pays attention to one of the unattention messages and sets it as the attention message (step S112).

  Next, in order to calculate the importance of the message of interest, the providing unit 150 initializes, for example, a value “0.00” to be added to the plurality of relevance calculated in step S86 in FIG. 22 ( Step S113).

  Next, the providing unit 150 determines whether or not the message of interest is a privilege notification message that informs about the privilege (step S114). For example, in the message box table of FIG. 5, the providing unit 150 determines whether one or more tags associated with the subject and the body of the message of interest are “privilege”, “coupon”, “discount”, If it is any of the words indicating the privilege such as "discount", it is determined that the message of interest is a privilege notification message.

  When providing unit 150 determines that the message of interest is a privilege notification message (step S114; Yes), a combination of the domain name and the subdomain name used by the source of the message of interest to identify the source of the message of interest Is specified based on, for example, the e-mail address used for transmitting the message of interest (step S115). The providing unit 150 may use any one of a domain name only, a subdomain name only, and a global IP (Internet Protocol) address instead of a combination of a domain name and a subdomain name.

  Thereafter, the providing unit 150 determines in the browsing history table of FIG. 21 that the URL associated with the user ID of the user authenticated in step S81 of FIG. One or more URLs including the combination with the subdomain name are specified, and the date and time respectively associated with the specified one or more URLs are specified. This is for specifying the date and time when the authenticated user browsed the content of the source of the privilege notification message (step S116).

  After that, the providing unit 150 specifies the latest date and time from the specified date and time, and calculates the elapsed time from the latest date and time to the system date and time (step S117). Thereafter, the providing unit 150 calculates a weighting coefficient having a larger value as the elapsed time is shorter (step S118), and weights the basic addition value having a value “1.00” with the calculated weighting coefficient. Thereafter, the providing unit 150 sets the added value of the message of interest as a weighted basic added value (Step S119). The more recent the date and time when the user browsed the content, the more usually the user has not lost interest in the products and the like published in the content, so the user is notified by the message itself and the message transmitted by the entity that published the content. This is because privileges that are more important to the user.

  After executing step S119, the providing unit 150 calculates the importance of the message of interest by adding the addition value calculated based on the elapsed time to the plurality of degrees of association calculated in step S86 of FIG. (Step S120). After that, the providing unit 150 returns to step S111 and repeats the above processing.

  In a case where it is determined in step S114 that the message of interest is not a privilege notification message and is a message that does not notify a privilege (hereinafter, a privilege non-notification message) (step S114; No), the providing unit 150 similarly performs step S120. Execute. In this case, the providing unit 150 calculates the importance of the message of interest by adding the added value of the value “0” initialized in step S113 to the plurality of degrees of association. After that, the providing unit 150 returns to step S111 and repeats the above processing.

  Accordingly, when the multiple relevance of the privilege notification message and the multiple relevance of the privilege non-notification message have the same value, the providing unit 150 sets the importance of the privilege notification message to be greater than the importance of the privilege non-notification message. Is also a large value. This is because the added value of the privilege non-notification message is always the initial value “0.00”. In addition, the providing unit 150 calculates the greater the importance of the privilege notification message as the date and time when the user browses the content of the source of the privilege notification message is newer.

  In step S111, when the providing unit 150 determines that there is no unattention message (step S111; No), the providing unit 150 ends the execution of the importance calculation process.

  Thereafter, in step S88 in FIG. 22, the providing unit 150 changes the display order to be higher for a message calculated with a higher importance.

  According to these configurations, the providing unit 150 sets the importance of the privilege notification message to a larger value as the date and time when the content of the source of the privilege notification message is browsed is larger, so that the privilege that is more important for the user is Can be reliably notified.

<Modification 2 of Embodiment 3>
In the third embodiment, it has been described that the providing unit 150 of the providing apparatus 100 calculates the importance based on whether the message is read or unread.

  However, the present invention is not limited to this. The providing unit 150 may set the importance of the privilege notification message that informs about the privilege of the product or the like to a content in which a product or the like belonging to the same or similar genre as the genre of the product or the like is listed. The higher the number of times the user has browsed, the higher the calculation may be.

  The information storage device 190 according to the present modification stores a content table as shown in FIG. 25 in order to specify a product or the like published in the content. In the content table of FIG. 25, a plurality of URLs in which the URL of the content, the tag of the content, the name of the product or the like posted in the content, and the genre ID for identifying the genre to which the product or the like belongs are associated. Data is stored.

  In addition, in order to specify a genre of a product or the like, the information storage device 190 of the providing device 100 stores a product genre table as shown in FIG. The product genre table stores a plurality of pieces of data in which genre IDs are associated with names of one or more products or the like belonging to the genre identified by the genre ID.

  Further, in order to specify a genre similar to a certain genre, the information storage device 190 stores a similar genre table as shown in FIG. The similar genre table stores a plurality of pieces of data in which a genre ID is associated with a genre ID of one or more genres similar to the genre identified by the genre ID. The genre similar to a certain genre includes, for example, a genre to which a product or the like used simultaneously with or related to the certain genre belongs. For example, the genre similar to the genre to which the “fishing trip” belongs includes the genre to which the “fishing rod” used in the “fishing trip” belongs.

  The providing apparatus 100 executes a tag extraction process (not shown) at a predetermined timing, as in the first embodiment. When the providing apparatus 100 starts executing the tag extraction process, it focuses on one of the unattentioned records included in the content table of FIG. 25, sets the content at the URL stored in the noted record as the attention content, and One or more tags are extracted.

  Next, the providing apparatus 100 focuses on one of the unattentioned tags among the extracted one or a plurality of tags, and determines whether or not the attentioned tag represents the name of a product or the like. It is determined whether the word represented by the focused tag is stored in the product genre table of FIG. If the providing device 100 determines that the word represented by the noted tag is not stored in the product genre table, the providing device 100 repeats the above process from the process of focusing on one of the unattentioned tags until there is no unattentioned tag. .

  When the providing apparatus 100 determines that the word represented by the noted tag is stored in the product genre table, the word represented by the noted tag is the name of a product or the like, and the product or the like having the name is the content of interest. It is determined that it is published in. In addition, the providing device 100 specifies a genre ID associated with one or more names including the name in the product genre table of FIG. 26 in order to specify the genre of the posted product or the like.

  After that, the providing apparatus 100 stores the URL of the content of interest, the tag of the content of interest, the name of the product or the like published in the content of interest, and the genre ID of the genre to which the product or the like belongs in the content table of FIG. Save the associated data. After that, the providing apparatus 100 repeats the above processing from the processing focusing on one of the unattention records until the unattention record included in the content table in FIG. 25 disappears, and then terminates the execution of the tag extraction processing.

  The providing unit 150 according to the present modification executes an importance calculation process as shown in FIG. 28 instead of step S87 in FIG. 22 in order to calculate the importance of the privilege notification message based on the number of times of viewing the content. I do.

  When the importance calculation processing is started, the providing unit 150 executes the same processing as steps S111 to S114 in FIG. 24 (steps S121 to S124). Thereby, the providing unit 150 focuses on one of the unfocused messages included in the message box table in FIG. 5 and sets it as the focused message, initializes the added value of the focused message to the value “0.00”, and sets the focused message to the privilege notification. Determine whether the message is a message.

  If the providing unit 150 determines that the message of interest is a privilege notification message (step S124; Yes), the name of the product or the like described in the message of interest and the genre to which the product or the like belongs are identified based on the tag of the message of interest. (Step S125). The method of specifying the name of the product or the like described in the message of interest and the genre to which the product or the like belongs is the same as the method of specifying the name of the product or the like posted in the content and the genre to which the product or the like belongs.

  Next, the providing unit 150 obtains one or more genre IDs associated with the genre ID of the specified genre in the similar genre table of FIG. 27 (step S126). This is for specifying one or a plurality of genres similar to the genre to which the product or the like described in the message of interest belongs.

  Thereafter, the providing unit 150 is associated with one of the genre ID of the genre to which the product or the like described in the message of interest belongs and the genre ID of the similar genre specified in step S126 in the content table of FIG. One or more URLs of the content are specified. This is for specifying a content in which a product or the like belonging to the same or similar genre as the genre of the product or the like described in the attention message is posted.

  Next, the providing unit 150 stores, from the browsing history table of FIG. 21, a record in which any of the specified one or more URLs and the user ID of the user authenticated in step S81 of FIG. 22 are stored. One or more records are acquired, and the number of records acquired is counted. This is for specifying the number of times that the content in which the product or the like belonging to the same or similar genre as the genre of the product or the like described in the message of interest is viewed by the authenticated user (step S127 in FIG. 28).

  Thereafter, the providing unit 150 calculates a weighting coefficient having a larger value as the number of times of browsing is larger (step S128), and weights, for example, a basic addition value having a value “1.00” with the calculated weighting coefficient. . Thereafter, the providing unit 150 sets the added value as a weighted basic added value (Step S129). As the number of times the user browses a certain content increases, the user usually has a stronger interest in a product or the like posted in the certain content or a product or the like belonging to the same or similar genre as the genre of the product or the like. I have. For this reason, a privilege notification message that informs the user of a privilege such as a product that the user is interested in is important to the user.

  After executing step S129, the providing unit 150 calculates the importance of the message of interest by adding the addition value calculated based on the number of times of browsing to the plurality of degrees of association calculated in step S86 of FIG. (Step S130). Thereafter, the providing unit 150 returns to step S121 and repeats the above processing.

  In a case where it is determined in step S124 that the message of interest is a privilege non-notification message (step S124; No), the providing unit 150 similarly executes step S130. In this case, the providing unit 150 calculates the importance of the message of interest by adding the addition value of the value “0” initialized in step S123 to the plurality of degrees of association. Thereafter, the providing unit 150 returns to step S121 and repeats the above processing.

  Accordingly, when the multiple relevance of the privilege notification message and the multiple relevance of the privilege non-notification message have the same value, the providing unit 150 sets the importance of the privilege notification message to be greater than the importance of the privilege non-notification message. Is also a large value. This is because the added value of the privilege non-notification message is always the initial value “0.00”. In addition, the providing unit 150 increases the importance of the privilege notification message as the number of times of browsing the content in which the product or the like belonging to the same or similar genre as the genre of the product or the like to which the privilege is notified by the privilege notification message is larger. calculate.

  In step S121, when the providing unit 150 determines that there is no unattention message (step S121; No), the providing unit 150 ends the execution of the importance calculation process.

  Thereafter, in step S88 in FIG. 22, the providing unit 150 changes the display order to be higher for a message calculated with a higher importance.

  According to these configurations, the providing unit 150 sets the privilege notification message as the number of times of browsing the content in which the product or the like belonging to the same or similar genre as the genre of the product or the like to which the privilege is notified by the privilege notification message is larger. Is set to a large value, it is possible to reliably notify a privilege that is more important to the user.

  In addition, the providing unit 150 specifies, in the time zone to which the system time belongs, the content in which the product or the like belonging to the same or similar genre as the genre of the product or the like to which the privilege is notified by the privilege notification message is viewed by the user. The greater the number of times performed, the higher the importance and display order of the privilege notification message may be. The time zone to which the system time belongs may be, for example, a time zone from a time 30 minutes before the system time to a time 30 minutes after the system time. An important message for the user is that, for example, a time zone during the day when working is different from a time zone before going to bed with a family.

<Variation 3 of Embodiment 3>
The providing unit 150 calculates the importance of the privilege notification message higher as the number of times of purchase of the product or the like belonging to the same or similar genre as the genre of the product or the like to which the privilege is notified in the privilege notification message is larger. May be.

  For this reason, the information storage unit 190 of the providing apparatus 100 according to the present embodiment stores a purchase history table as shown in FIG. The purchase history table stores a plurality of pieces of data in which a user ID, a URL of a content used by the user identified by the user ID to purchase a product or the like, and a purchase date and time of the product or the like are associated with each other. Is done.

  The providing unit 150 of the providing apparatus 100 according to the present embodiment calculates the importance based on the number of purchases of a product or the like. Therefore, in the second modification of the third embodiment, the importance calculating process described with reference to FIG. Is executed using the purchase history table of FIG. 29 instead of the browse history table of FIG. Accordingly, in steps S127 to S130, the providing unit 150 specifies the number of purchases of a product or the like belonging to the same or similar genre as the genre of the product or the like described in the message of interest, and the greater the specified number, the larger the number of purchases. The importance is calculated so as to be a value.

  Note that the providing unit 150 determines the importance and the display order of the message informing about the privilege of the product or the like by the number of times the product or the like belonging to the same or similar genre as the product or the like is purchased in the time zone to which the system time belongs. The higher the number, the higher it may be.

<Modification 4 of Embodiment 3>
In the third embodiment, the providing unit 150 of the providing apparatus 100 calculates the importance based on whether the message is read or unread. However, the present invention is not limited to this.

  If the user who is the destination of a message (hereinafter, referred to as an event notification message) that informs about the holding of an event for selling a product or the like has a history of purchasing the product or the like in the event, the providing unit 150 sets an event other than the event. May be higher in importance than the event notification message notifying the start of the event and the message not reporting any event (hereinafter referred to as an event non-notification message).

  For this purpose, the information storage unit 190 of the providing apparatus 100 according to the present modification stores a purchase history table as shown in FIG. In the purchase history table, data in which the user ID of the user, the name of the event in which the user participated, the name of the product or the like purchased by the user in the event, and the purchase date and time of the product or the like are associated with each other. Are stored multiple times.

  The providing unit 150 according to the present modification executes an importance calculation process as shown in FIG. 31 instead of step S87 in FIG. 22 in order to calculate the importance based on the purchase history in the event.

  When the importance calculation processing is started, the providing unit 150 executes the same processing as steps S111 to S113 in FIG. 24 (steps S131 to S133). Thereby, the providing unit 150 focuses on one of the unattentioned messages included in the message box table of FIG. 5 as the attention message, and initially sets the added value used for calculating the importance of the attention message to the value “0.00”. Become

  Next, the providing unit 150 determines whether or not the message of interest is an event notification message (Step S134). For example, when two tags “event” and “held” are associated with the tag of the message of interest, the providing unit 150 determines that the message of interest is an event notification message.

  When the providing unit 150 determines that the message of interest is a notification message (step S134; Yes), the name of the event whose notification is held by the message of interest, the product sold in the event, etc., based on the tag of the message of interest. Is specified (step S135).

  Thereafter, the providing unit 150 stores the user ID of the user authenticated in step S81 in FIG. 22, the name of the event specified in step S135, and the name of a product or the like in the purchase history table in FIG. One or more records are specified, and the number of the specified records is counted. After that, the providing unit 150 specifies the counted number of records as the number of times that the user who is the destination of the message of interest has purchased a product or the like sold in an event notified of being held in the message of interest (see FIG. 31). Step S136).

  Thereafter, the providing unit 150 determines whether the number of times specified in step S136 is equal to or greater than a predetermined number (step S137). Whether the user who is the destination of the message of interest is interested in the event, based on whether or not the product or the like sold in the event of which the notice is held by the attention message is repeatedly purchased a predetermined number of times or more. This is to determine whether or not it is.

  If the providing unit 150 determines that the specified number of times is equal to or more than the predetermined number of times (step S137; Yes), the providing unit 150 sets the target based on a description rule indicating a date and time such as “YYYY / MM / DD hh: mm: ss”. Identify the subject of the message and the date and time of the event described in the text. Next, the providing unit 150 calculates the grace time until the event date and time by subtracting the system date and time from the event date and time (step S138).

  Thereafter, the providing unit 150 calculates a weighting coefficient having a larger value as the grace time is shorter (step S139), and weights, for example, a basic addition value having a value “1.00” with the calculated weighting coefficient. Thereafter, the providing unit 150 updates the added value of the message of interest with the weighted basic added value (step S140). However, when the date and time of the event has already arrived, the providing unit 150 sets the addition value of the message of interest to the value “0.00”.

  When a user repeatedly purchases a product or the like at an event, the user is usually interested in holding the event. In addition, the user cannot participate in the event unless the message notifying the holding of the event is not confirmed before the date and time of holding the event. For this reason, as the date and time of the event approaches, the importance of the message for notifying the user of the event increases for the user.

  After executing step S140, the providing unit 150 calculates the importance of the message of interest by adding the addition value calculated based on the grace time to the plurality of degrees of association calculated in step S86 of FIG. (Step S141). Thereafter, the providing unit 150 returns to step S131 and repeats the above processing.

  If it is determined in step S134 that the message of interest is not an event notification message (step S134; No), or if it is determined in step S137 that the number of times the user has purchased a product or the like at the event is less than a predetermined number (step S134) In S137; No), the providing unit 150 similarly executes Step S141. In this case, the providing unit 150 calculates the importance of the message of interest by adding the added value of the value “0” initialized in step S133 to the plurality of degrees of association. Thereafter, the providing unit 150 returns to step S131 and repeats the above processing.

  Thereby, the providing unit 150 notifies the user of the event that the user has purchased the product or the like a predetermined number of times or more, and a plurality of relevance levels of the event notification message addressed to the user and other messages that are messages other than the event notification. When the plurality of degrees of association have the same value, the importance of the privilege notification message is set to a value larger than the importance of the other messages. This is because the added value of other messages is always the initial value “0.00”. Further, the providing unit 150 calculates the importance of the privilege notification message larger as the date and time of the event notified by the privilege notification message approaches. The providing unit 150 may calculate the importance of the privilege notification message to be larger as the number of times of purchase of the product or the like in the event notified by the privilege notification message is larger.

  In step S131, when the providing unit 150 determines that there is no unfocused message (step S131; No), the providing unit 150 ends the execution of the importance calculation process.

  Thereafter, in step S88 in FIG. 22, the providing unit 150 changes the display order to be higher for a message calculated with a higher importance.

  According to these configurations, the provision unit 150 sets the importance of the privilege notification message to a larger value as the date and time of the event notified by the event notification message approaches, so that the holding of the event that is important to the user is increased. Can be notified reliably.

  Note that the event notification message may be a message informing about distribution of special content that specializes in a product or the like. When the user who is the destination of the event notification message has purchased the product or the like in the special content more than a predetermined number of times, the providing unit 150 determines the importance and the display order of the event notification message as compared with the case where there is no history. May be higher. This is because, when a user repeatedly purchases a product or the like with a special content, the user is usually interested in distributing the special content. Further, the providing unit 150 may calculate the importance of the event notification message higher as the distribution date and time of the special content notified by the event notification message approaches. Unless the message notifying the distribution of the special content is not confirmed before the distribution date of the special content, the user cannot view the special content, so the importance of the message notifying the distribution increases as the distribution date approaches. Is higher.

  For this purpose, the information storage unit 190 of the providing device 100 may store the URL or name of the special content in the purchase history table of FIG. 30 instead of the event name. The providing unit 150 of the providing apparatus 100 may use the URL or the name of the special content instead of the event name in the importance calculation process of FIG.

<Modification 5 of Embodiment 3>
In the third embodiment, the providing unit 150 of the providing apparatus 100 determines in step S87 of FIG. 22 based on the degree of association indicating the degree of association between the message and a plurality of browsed contents browsed by the user in the past. Although it has been described that the importance is calculated, the invention is not limited to this.

  After calculating the importance based on the singular degree of association between the latest browsed content and the message, the providing unit 150 determines that the more recent the date and time of browsing the content of the website that sells the product or the like described in the message, the more important the The degree may be changed to a higher value. This is because the items included in the content most recently viewed by the user are generally important to the user, and thus the more relevant the message is to the content, the more important to the user. Also, for the same reason, the more recently visited websites sell products and the like that are more important to the user, and the message that describes such products and the like is more important to the user. .

  For this purpose, the information storage unit 190 of the providing apparatus 100 according to the present modification stores a website table as shown in FIG. The website table stores in advance a plurality of data in which a combination of a domain name and a subdomain name used on the website and names of one or more products sold on the website are associated with each other. ing. The information storage unit 190 may store any one of only the domain name, only the subdomain name, and the global IP address instead of the combination of the domain name and the subdomain name.

  The information storage unit 190 stores a message box table in which a plurality of records are stored as shown in FIG. Each record of the message box table includes a user ID of a user who is a destination of the message, a URL, a subject, a body, a tag, a singular relevance, a display order of the message, a product described in the message, and the like. Is associated with a flag indicating “unread” or “read”.

  The providing device 100 according to the present modification executes a storage process (not shown) to store a message in the message box table of FIG.

  In the storage processing, the generation unit 110 in FIG. 4 generates a message notifying a price reduction of a product such as “fishing rod” or “fishing trip”, based on the user's action history. Thereafter, the storage unit 120 stores the user ID of the user who is the destination of the message notifying the price reduction of the fishing rod, the URL of the generated message, the subject, the body, and the tags “fishing”, “fishing rod”, and “price reduction”. And the name of the product or the like “fishing rod” described in the message and a flag indicating “unread” are generated. After that, the storage unit 120 stores the generated data in the message box table of FIG. Similarly, the storage unit 120 stores the user ID of the user who is the destination of the message notifying the price reduction of the fishing trip, the URL of the generated message, the subject, the body, and the tags “fishing”, “travel”, and “ It generates data in which "price reduction", the name of the product etc. described in the message "fishing trip", and a flag indicating "unread" are associated with each other. After that, the storage unit 120 stores the generated data in the message box table.

  The providing device 100 executes a content providing process as shown in FIG. When the content providing process is started, the providing device 100 executes a process similar to steps S81 to S85 in FIG. 22 (steps S151 to S155). As a result, a predetermined number of browse contents are specified in the new order.

  After that, the providing unit 150 of the providing device 100 uses the method described in the first embodiment for each of the plurality of messages stored in the message box table of FIG. It is calculated on the basis of (step S156).

  Here, for the sake of simplicity, an example will be described in which the latest browsed content is a web page describing sea fishing, and tags “sea” and “fishing” are attached to the latest browsed content. This will be described below.

  For the message that notifies the price reduction of the fishing rod stored in the message box table of FIG. 33, the providing device 100 includes only the tag “fishing” among the tags “fishing”, “fishing rod”, and “price reduction” of the message. Is determined to match the tag of the latest browsed content. Therefore, the providing apparatus 100 calculates the singular relevance as “0.50” by dividing the number of matching tags “1” by the total number of tags of the latest browsed content “2”. Similarly, the singular relevance is calculated as “0.50” for the message notifying the price reduction of the fishing trip.

  After that, the providing unit 150 calculates the importance of each of the plurality of messages stored in the message box table based on the singular relevance by the method described in the first embodiment (step S157 in FIG. 34). Since both the message notifying the price reduction of the fishing rod and the message notifying the price reduction of the fishing trip are unread messages, the providing unit 150 adds the additional value “1.00” used for the unread message to the singular association degree “0.50”. Then, the importance is calculated as “1.50”.

  After that, the providing unit 150 executes the importance changing process of FIG. 35 in which the importance is changed based on the browsing date and time of the website that sells the product or the like described in each message (step S158).

  When the importance change processing is started, the providing unit 150 executes the same processing as steps S101 and S102 in FIG. 23 (steps S171 and S172). Thereby, the providing unit 150 sets one of the unattention messages stored in the message box table of FIG. 33 as the attention message.

  Next, the providing unit 150 specifies the name of a product or the like associated with the URL of the message of interest in the message box table of FIG. This is for specifying the name of the product or the like described in the message of interest (step S173).

  Thereafter, the providing unit 150 executes the same processing as in steps S104 and S105 in FIG. 23 (steps S174 and S175 in FIG. 35). Accordingly, the providing unit 150 replaces one of the unviewed browsing contents among the browsing contents in the predetermined number of URLs acquired from the browsing history table in FIG. 21 in step S155 in FIG. And

  Thereafter, the providing unit 150 specifies a combination of a domain and a sub-domain of the website composed of the noted browsing content based on the URL of the noted browsing content, and sells the website based on the specified combination. A group of products etc. is specified (step S177 in FIG. 35).

  For example, the providing unit 150 extracts “market.xxx.com” from the URL “http://market.xxx.com/C011.html” of the noted browse content stored in the browse history table of FIG. In the 32 website tables, the names “fishing rod” and “fish hook” of a plurality of products etc. associated with the extracted “market.xxx.com” are specified. This is for specifying a plurality of products sold by an Internet mall that publishes contents using “market.xxx.com”. Similarly, for example, the providing unit 150 extracts “travel.xxx.com” from the URL “http://travel.xxx.com/C012.html” of the browsed content and uses “travel.xxx.com”. To identify products such as "fishing trips" sold by a travel site that publishes content.

  Thereafter, the providing unit 150 determines whether or not the product or the like group of the website specified in step S176 of FIG. 35 includes the product or the like of the noticed message specified in step S173 (step S177). This is to determine whether or not the product or the like described in the notice message is sold on the website.

  At this time, when the providing unit 150 determines that the product or the like of the website does not include the product or the like of the message of interest (Step S177; No), the providing unit 150 repeats the above processing from Step S174.

  On the other hand, when the providing unit 150 determines that the product or the like of the website includes the product or the like of the message of interest (step S177; Yes), the providing unit 150 specifies the target viewing content stored in the viewing history table of FIG. The elapsed time from the date and time to the system date and time is calculated (step S178). This is for calculating the elapsed time from the date and time when the attention viewing content was viewed.

  After that, the providing unit 150 calculates a weighting coefficient that is a weighting factor for the importance level and is equal to or greater than the value “1.00” so that the larger the elapsed time, the larger the value (step S179). This is because websites viewed more recently by the user sell more important products and the like to the user.

  After that, the providing unit 150 weights the importance of the message of interest with a weighting coefficient to change the value to a value larger than before the change (step S180), and then repeats the above processing from step S171.

  For example, the importance of the message notifying the price reduction of the fishing rod and the importance of the message notifying the price reduction of the fishing trip are calculated to be the same value “1.50” in step S157 in FIG. However, as shown in the browsing history table of FIG. 21, the website of the Internet mall that sells “fishing rods” using “market.xxx.com” is assigned by the user identified by the user ID “U001” in January 2018. Viewed at 12:00 on the 1st of the month. In contrast, a travel site that sells "fishing trips" using "travel.xxx.com" was viewed by the user at 1:00 on the same day. That is, the elapsed time from the browsing date of the Internet mall that sells “fishing rods” is 11 hours shorter than the browsing time of the travel site that sells “fishing trips”. For this reason, the importance of the message notifying the price reduction of the fishing rod is changed to a value higher than the importance of the message notifying the price reduction of the fishing trip.

  In step S174 of FIG. 35, when providing unit 150 determines that there is no unobserved browse content (step S174; No), the above processing is repeated from step S171.

  In step S171, when the providing unit 150 determines that there is no unattention message (step S171; No), the providing unit 150 ends the execution of the importance changing process.

  After the importance changing process is performed in step S158 of FIG. 34, the providing unit 150 changes the display order based on the importance of each message (step S159). Therefore, based on the changed importance, the providing unit 150 changes the display order of the message notifying the price reduction of the fishing rod to be higher than the display order of the message notifying the price reduction of the fishing trip.

  After that, the providing unit 150 performs the same processing as steps S89 to S91 in FIG. 22 (steps S160 to S162), and ends the execution of the content providing processing.
