(First embodiment)
First, the function and configuration of the information processing apparatus 10 according to the first embodiment will be described with reference to FIGS. The information processing apparatus 10 is a server apparatus that presents a seasonal keyword near the current position of the portable user terminal T to the user and provides the user with content related to the selected keyword. In the example of FIG. 1, the topic list screen P is first displayed on the terminal of the user near Shinbashi. On this topic list screen P, five seasonal keywords in the vicinity of Shimbashi are displayed. Thereafter, when the user selects “Store B” from the presented keywords, the content related to the store information of the keyword “Store B” is displayed as the detailed screen Q.

  As shown in FIG. 2, the information processing apparatus 10 includes a word attribute storage unit (third and fourth storage unit) 11, a content information storage unit (first storage unit) 12, and a collection unit 13 as functional components. A word registration unit (area specifying unit) 14, an association unit (area specifying unit, content extraction unit, storage unit) 15, a word storage unit (second storage unit) 16, and a distribution unit 17. The information processing apparatus 10 can access information (transmission information) posted on a diary, a bulletin board, a blog, a microblog, a social networking service (SNS), or the like via the Internet N which is a communication network. . Further, any number of information processing apparatuses 10 can be provided via a predetermined communication network (not shown) configured by a mobile communication network or another wireless communication network (for example, WiFi or Bluetooth (both are trademarks or registered trademarks)). The user terminal T can be communicated.

  As shown in FIG. 3, the information processing apparatus 10 includes a CPU 101 that executes an operating system, application programs, and the like, a main storage unit 102 that includes a ROM and a RAM, and an auxiliary storage unit 103 that includes a hard disk. The communication control unit 104 includes a network card, an input unit 105 such as a keyboard and a mouse, and an output unit 106 such as a monitor. Each function of the information processing apparatus 10 reads predetermined software on the CPU 101 or the main storage unit 102, operates the communication control unit 104, the input unit 105, the output unit 106, and the like under the control of the CPU 101. This is realized by reading and writing data in the unit 102 and the auxiliary storage unit 103. Data and databases necessary for processing are stored in the main storage unit 102 and the auxiliary storage unit 103.

  In FIG. 3, the information processing apparatus 10 is illustrated as being configured by one computer, but the server function may be distributed to a plurality of computers. For example, the information processing apparatus 10 or an information processing system corresponding to the information processing apparatus 10 may be configured by a computer including the storage units 11, 12, and 16 and a computer including other functional components.

  Returning to FIG. 2, the word attribute storage unit 11 is means for previously storing word attribute information indicating the attribute of each word, and is referred to by a word registration unit 14 described later. The word attribute information includes a word and its attribute. For example, it is conceivable to prepare word attribute information related to words that frequently appear on the Internet N or words that are talked about in society, but the word selection criteria may be arbitrarily determined. An example of word attribute information is shown in FIG. In this example, the word attribute storage unit 11 has word attribute information in which an attribute “area” is associated with a word indicating a region name or a station name, and an attribute “genre” with respect to a word indicating a facility category. The associated word attribute information is stored. Examples of words whose attribute is “genre” include words related to restaurants such as “Italian”, “ramen”, “sushi”, and names of chain stores. It may be determined arbitrarily.

  In the present embodiment, two types of “area” and “genre” are set as the word attributes, but the word attributes may be arbitrarily determined. Hereinafter, a word (area-related phrase) having the attribute “area” is referred to as an “area word”, and a word (genre-related phrase) having the attribute “genre” is referred to as a “genre word”. A word that is not registered in the word attribute storage unit 11 is referred to as “other attribute word”.

  The content information storage unit 12 is a unit that stores in advance content information indicating various types of information related to content, and is referred to by the association unit 15 described later. The content information includes a content ID that is an identifier for uniquely identifying the content, and the genre, name, address, and position (latitude and longitude) of the facility related to the content. Examples of facilities include stores and sightseeing spots, but the types of facilities are not limited. The genre and name of the facility are terms related to the content, and the address and latitude / longitude of the facility are terms indicating an area corresponding to the content. The item “genre” of the content information is a concept different from the word attribute “genre” indicated by the word attribute information. The items (configuration) of the content information are not limited to the example of FIG.

  An example of content information is shown in FIG. For example, from FIG. 5, the content identified by the content ID “aaa001” relates to the facility “Ramen shop P” belonging to the genre “Ramen”, and the address of the facility is “Chiyoda-ku, Tokyo ...” It can be seen that the position (latitude and longitude) is “X1, Y1”.

  The collection unit 13 is means for collecting transmission information existing on the Internet N. The collection unit 13 collects information (transmission information) posted on the Internet by accessing various services such as a diary, bulletin board, blog, microblog, and SNS. The outgoing information corresponds to one article for a diary or blog, one thread for a bulletin board, and one tweet for a microblog. The collection unit 13 may collect information using an application programming interface (API) provided from each Internet service, or may collect information using a crawling technique. The method of collecting information is not limited to these, and any method may be used. The collection unit 13 outputs the acquired transmission information to the word registration unit 14. The collection unit 13 performs such collection processing regularly or always.

  The word registration unit 14 is means for storing the word included in the transmission information input from the collection unit 13 in the word storage unit 16. The word registration unit 14 extracts text included in the transmission information, decomposes the text into one or more words by morphological analysis, and extracts only nouns from the one or more words. The word registration unit 14 may extract text by analyzing an image included in the transmission information.

  Subsequently, the word registration unit 14 reads word attribute information corresponding to each extracted noun from the word attribute storage unit 11. If no word attribute information can be extracted in this process, the word registration unit 14 ends the process related to the transmission information at this point. On the other hand, when one or more word attribute information can be extracted, the word registration unit 14 generates word information by associating the transmission information ID for specifying the transmission information with the extracted one or more word attribute information. The word information is stored in the word storage unit 16. When another word other than the area word or the genre word (that is, another attribute word) exists, the word registration unit 14 also includes the other attribute word in the stored word information.

  When generating the word information, the word registration unit 14 uses a URL (Uniform Resource Locator) indicating a storage location of the transmission information on the Internet N, and an identifier attached to the transmission information in the microblog service or SNS. You may use it as transmission information ID as it is.

  When the word information is generated and stored, the word registration unit 14 outputs the word information and the corresponding transmission information to the association unit 15. The word registration unit 14 performs the above-described processing for each input transmission information.

  The associating unit 15 is means for adding information on related contents to the word information stored in the word storage unit 16 that satisfies a predetermined condition. The associating unit 15 executes the above-described processing for each set of input word information and transmission information.

  First, the associating unit 15 determines whether or not an area word is included in the input word information. If the area word does not exist, the associating unit 15 ends the processing related to the word information. On the other hand, when an area word exists (that is, when an area word exists in the transmission information), the associating unit 15 determines whether or not a genre word or another attribute word is included in the word information. If these words do not exist in the word information, the associating unit 15 ends the processing related to the word information.

  When at least one of the genre word and the other attribute word exists (that is, when the genre word or the other attribute word exists in the transmission information), the associating unit 15 displays the content information corresponding to the area word as the content information storage unit 12. Extract from For example, the associating unit 15 may extract content information in which the facility address includes an area word. Further, if the area word indicates a station name, the associating unit 15 may extract content information of facilities located around the station (for example, within 1 km). If the content information corresponding to the area word cannot be extracted, the associating unit 15 terminates the processing related to the word information at this point.

  When the content information corresponding to the area word can be extracted, the associating unit 15 determines whether or not the genre word or the other attribute word included in the word information exists in the content information. If neither the genre word nor the other attribute word exists, the associating unit 15 finishes the processing related to the word information at this point. On the other hand, if at least one of the genre word and the other attribute word exists in the content information, that is, if there is a common phrase between the word information and the content information, the associating unit 15 selects an area corresponding to the content information. Identify. This area is used for search processing in the distribution unit 17 described later, and can therefore be referred to as a “search area”. The search area may be a section such as a prefecture or a municipality itself, or may be a predetermined section that is divided in a mesh shape in advance. Further, the location of the facility indicated by the content information and the latitude and longitude itself may be specified as the search area.

  When the search area corresponding to the content information is specified, the associating unit 15 adds to the corresponding word information in the word storage unit 16 an area code (area information) indicating the search area and the ID ( Related content ID).

In summary, the associating unit 15 adds related content information to the transmission information when the following requirements (a) to (d) are all satisfied for the transmission information (input word information). Append.
(A) The transmission information includes an area word.
(B) The transmission information includes a genre word or another attribute word.
(C) Content information corresponding to the area word exists.
(D) The content information includes a genre word or other attribute word common to the transmission information.

  The word storage unit 16 is means for storing word information generated by the word registration unit 14 and updated by the association unit 15 in some cases. In the example of FIG. 6, related content information (area code and related content ID) is added to the two word information identified by the transmission information IDs “xxxxxxxx1” and “xxxx2”, but the transmission information “xxxx3” No related content information is added to the specified word information.

  The distribution unit 17 is a means for distributing seasonal keywords and contents related to the periphery of the current position of the terminal user to the user terminal T. Below, the function of the delivery part 17 is demonstrated, also showing the process in the user terminal T.

  When an operation for displaying the topic list screen P shown in FIG. 1 is performed on the user terminal T, the user terminal T acquires position information indicating the current position of the terminal itself. The method for acquiring the position information is arbitrary. For example, if the user terminal T includes a GPS module, it is possible to receive radio waves from a plurality of GPS (Global Positioning System) satellites and calculate the current position from their intensities. Further, the user terminal T may calculate the current position from the strength of radio waves received from a plurality of wireless communication base stations based on standards such as WiFi and Bluetooth (both are trademarks or registered trademarks). The user terminal T may calculate the current position by using these two methods together. Alternatively, the user terminal T may acquire map information or an address selected or input by the user as position information of the user terminal T. The user terminal T transmits the acquired position information to the information processing apparatus 10.

  The distribution unit 17 receives the position information, acquires the current position of the user terminal T, and acquires an area code indicating an area including the current position. Subsequently, the distribution unit 17 extracts word information corresponding to the area code and including the area code and the related content ID from the word storage unit 16. Subsequently, the distribution unit 17 sets the genre word and other attribute word indicated by the extracted word information as keywords to be displayed on the topic list screen P. Subsequently, the distribution unit 17 generates a web page of the topic list screen P including the set keyword and the corresponding related content ID, and transmits the page to the user terminal T. Thereby, the topic list screen P as shown in FIG. 1 is displayed on the user terminal T.

  The number of keywords to be displayed on the topic list screen P and the display order may be arbitrarily determined. For example, the distribution unit 17 may arrange the keywords in time series based on the posting date of the transmission information, or may arrange the keywords in order from the one corresponding to the content close to the current position of the user terminal T. The distribution unit 17 may rearrange the keywords according to the ranking calculated by a predetermined algorithm.

  When the terminal user selects one keyword on the topic list screen P, the user terminal T transmits the related content ID associated with the keyword to the information processing apparatus 10. The distribution unit 17 receives the related content ID, and extracts content information corresponding to the ID from the content information storage unit 12. And the delivery part 17 produces | generates the web page of the detailed screen Q using the extracted content information, and transmits the page to the user terminal T. Thereby, a detailed screen Q as shown in FIG. 1 is displayed on the user terminal T.

  Next, the operation of the information processing apparatus 10 will be described with reference to FIG. 7, and the information processing method according to the present embodiment will be described. FIG. 7 shows processing related to one piece of outgoing information, and the information processing apparatus 10 executes the processing shown in FIG. 7 for each collected outgoing information.

  First, the collection unit 13 collects one transmission information on the Internet N (step S11). Subsequently, the word registration unit 14 extracts an area word, a genre word, or another attribute word from the transmission information, generates word information including the extracted word, and stores it in the word storage unit 16 (step S12, area identification) Step).

  Subsequently, the associating unit 15 determines whether or not all of the following conditions (a) to (d) are satisfied. If all the conditions are satisfied, the area code and the related content ID are associated with the registered word information. (Step S17, storage step).

(A) The transmission information includes an area word (step S13 (area specifying step); YES).
(B) The transmission information includes a genre word or another attribute word (step S14; YES).
(C) Content information corresponding to the area word exists (step S15 (content extraction step); YES).
(D) The content information includes a genre word or other attribute word common to the transmission information (step S16; YES).

  If any one of the above conditions (a) to (d) is not satisfied (“NO” in any of steps S13 to S16), the associating unit 15 ends the process related to one transmission information at that time.

  As described above, according to the present embodiment, an area corresponding to outgoing information is first identified, and then content information corresponding to that area is extracted. Thereby, the content information corresponding to the transmission information can be obtained through the element called area. If there is a common genre word or other attribute word in both pieces of information, the transmission information and content information are associated with an area code indicating a search area corresponding to the content information (search Information) is generated and stored in the word storage unit 16. Thereby, the posted transmission information (that is, information including some topic) and the content information including a common phrase between the transmission information are associated with each other through an element called area. The word information obtained in this way makes it possible to efficiently provide information that is a topic in the vicinity of a place to a user at the place.

  In addition, not only the commonality of the areas but also both pieces of information are associated for the first time when the transmission information and the content information have a common word / phrase, so the topic indicated by the transmission information and the content can be accurately associated. Thereby, improvement of search accuracy can be expected.

  By generating word information as shown in FIG. 6 and holding it for search processing, the user can obtain a keyword that is a topic around the current location as shown in FIG. Furthermore, the user can access the content corresponding to the keyword only by selecting the keyword of interest. That is, the content can be easily viewed without inputting a keyword separately. If the keyword display order is controlled based on the posting date, ranking, etc., the user can obtain “at that time”, “at that location”, and “seasonal” information.

(Second Embodiment)
Next, the information processing apparatus 10 according to the second embodiment will be described. The second embodiment is different from the first embodiment in the method for specifying the area corresponding to the transmission information, which is executed by the associating unit 15. Since other configurations of the present embodiment are the same as those of the first embodiment, description thereof is omitted.

  The association unit 15 first determines whether or not an area word is included in the input word information, as in the first embodiment. If there is an area word, the associating unit 15 executes the subsequent processing as in the first embodiment.

  On the other hand, if the area word does not exist, the associating unit 15 does not end the processing related to the input word information at this time, but subsequently determines whether or not the corresponding outgoing information includes position information. judge. Examples of the position information included in the transmission information include an address described in an article and a latitude / longitude added as metadata such as a geotag. However, the type of location information is not limited, and any location information can be used as long as it can identify some area from the location information.

  If the location information is not included in the transmission information, the associating unit 15 ends the processing related to the input word information at this point.

  On the other hand, if the location information is included in the transmission information, the associating unit 15 specifies an area from the location information. For example, the associating unit 15 may specify an area corresponding to the acquired latitude / longitude or address by referring to map information held in advance. Further, the associating unit 15 may specify the area of the transmission information using the position information (latitude and longitude) of each piece of content information stored in the content information storage unit 12. Specifically, the associating unit 15 compares the latitude and longitude indicated by the transmission information with the latitude and longitude of each piece of content information in the content information storage unit 12, and the distance between the two points is within a predetermined threshold (for example, If it is within 1 km), the area indicated by the content information is specified as the area of the transmission information.

  When the area of the transmission information is specified, the associating unit 15 determines whether or not a genre word or another attribute word is included in the word information, as in the first embodiment. When at least one of these words exists (that is, when a genre word or another attribute word exists in the transmission information), the associating unit 15 stores content information corresponding to the specified area as content information. Extract from part 12. The content information extraction method at this time is the same as in the first embodiment. Subsequent processing performed when content information can be extracted is the same as that in the first embodiment.

That is, when the following requirements (a ′) to (d) are satisfied for the transmission information (input word information), the associating unit 15 adds the related content information to the transmission information. The following (a ′) and (c ′) are different from the first embodiment.
(A ′) The transmission information includes an area word or position information.
(B) The transmission information includes a genre word or another attribute word.
(C ′) Content information corresponding to either the area word or the area specified from the position information exists.
(D) The content information includes a genre word or other attribute word common to the transmission information.

  Therefore, the information processing method in the second embodiment can be shown as shown in FIG. The processing of steps S21 to S23 is the same as the processing of steps S11 to S13 in the first embodiment. However, when the transmission information does not include an area word in step S13 (step S13; NO), the associating unit 15 further determines whether or not the transmission information includes position information (step S28). If the transmission information includes position information (step S28; YES), the same processes of steps S24 to S27 as steps S14 to S17 in the first embodiment are executed. However, in step S25, the associating unit 15 determines whether there is content information corresponding to either the area word or the area specified from the position information.

  Also by such 2nd Embodiment, the effect similar to 1st Embodiment is acquired.

  In this embodiment, when the associating unit 15 specifies the area of the transmission information, first, the presence / absence of an area word is determined, and then the presence / absence of position information in the transmission information is determined as necessary. Only the determination based on the position information may be performed without checking the word.

  The present invention has been described in detail based on the embodiments. However, the present invention is not limited to the above embodiment. The present invention can be variously modified without departing from the gist thereof.

  In each of the above-described embodiments, the association unit 15 associates both pieces of information when a common phrase exists in both the transmission information and the content information. However, the association unit 15 also includes a case where a phrase other than the common phrase exists. That association may be performed.

  Specifically, the associating unit 15 may associate both pieces of information when there is a phrase related to both the word information and the content information. Here, “there is a phrase related to both the word information and the content information” means that not only a common (matching) phrase exists in both but also a similar phrase exists in both. It is a concept that includes. As an example of the similarity relationship, there is a case where a phrase included in one information corresponds to a higher concept or a lower concept of the phrase included in the other information (for example, “noodles” and “ramen”). In addition, the case where both words and phrases are shaken (for example, “cafe” and “cafeteria”, katakana notation and hiragana notation, etc.) is also a kind of similar relationship.

  The association unit 15 may use a word / phrase correspondence table prepared in advance or may use a predetermined learning algorithm in order to determine related words / phrases. In this case, the condition (d) in each of the above embodiments is rephrased as “(d ′) content information includes a genre word or other attribute word related to the genre word or other attribute word in the transmission information”. Can do.

  In each of the embodiments described above, the associating unit 15 executes the process for the genre word and the other attribute word as a word other than the area word. However, the process may be performed based on only one of these words. That is, in the processing related to the conditions (b) and (d) in the above embodiments, the associating unit 15 may determine the presence of only one of the genre word and the other attribute word.

  In each of the above embodiments, the collection unit 13 collects transmission information on the Internet N, but the range (communication network) in which the transmission information is collected is not limited.

  In each of the above embodiments, the word registration unit 14 extracts a word by performing morphological analysis on the transmission information. However, the information processing apparatus extracts a word composed of a plurality of words, and searches using the word and phrase in the same manner as in each of the above embodiments. Business information may be generated.

  In the above embodiments, when the terminal user selects one keyword on the topic list screen P, the content information associated with the keyword is transmitted to the user terminal T, but the content distribution method is not limited to this. For example, the information processing apparatus 10 and the user terminal T may be configured such that a topic list (one or more keywords) and content information corresponding to each keyword are simultaneously sent to the terminal T. In this case, the distribution unit 17 extracts one or more keywords in the same manner as in the above embodiments, and then acquires one or more pieces of content information from the content information storage unit 12 based on the related content ID corresponding to each keyword. Extract. Then, the distribution unit 17 transmits the extracted keyword and content information to the user terminal T. The user terminal T first displays the topic list screen P based on these pieces of information, and displays the detailed screen Q without communicating with the information processing apparatus 10 in response to subsequent keyword selection.
