[1. Information display processing]
FIG. 1 is a diagram illustrating an example of information display processing according to the embodiment. In FIG. 1, the information display process is executed by the terminal device 2, which is an example of the information display device. The information display process is a process of displaying the content provided from the information providing device 1 in the terminal device 2.

  The information providing device 1 is communicably connected to the terminal device 2 via a network, and provides the first content and the second content to the terminal device 2 in response to a distribution request from the terminal device 2. In addition, the information providing apparatus 1 selects a search keyword related to the first content or the like, and transmits the information of the search keyword to the terminal device 2 as search target information. In the following example, the first content is content including text, and is, for example, an article such as news or a blog. The second content is content that includes the title and image of the first content and also includes link information for transitioning to the first content.

  The terminal device 2 is a smart device such as a smartphone or a tablet terminal, and is a mobile terminal device capable of communicating with an arbitrary server device via a wireless communication network such as 3G (Generation) or LTE (Long Term Evolution). is there. A touch panel is used for the terminal device 2. The user U of the terminal device 2 can perform various operations by touching the display surface 80 (hereinafter referred to as the screen 80) of the display unit 33 with a finger or a stylus. The terminal device 2 may be not only a smart device, but also an information processing device such as a notebook PC (Personal Computer), a desktop PC, a mobile phone, and a PDA (Personal Digital Assistant).

  When the user U performs an operation for touching the screen 80 to acquire the content, the terminal device 2 requests the content from the information providing apparatus 1 (step S1). When there is a request for content from the terminal device 2, the information providing apparatus 1 selects a search keyword based on information about the requested content and the like, and performs a selection process of selecting the selected search keyword (step S2).

  The information providing device 1 performs a providing process of providing the content requested by the terminal device 2 and the information of the search keyword selected in step S2 (hereinafter referred to as search target information) to the terminal device 2 (step S3). ). As a result, the content and the search target information are transmitted from the information providing device 1 to the terminal device 2 (step S4).

  Hereinafter, it is assumed that the content requested from the terminal device 2 in step S1 is the first content C11 shown in FIG. In this case, the information providing apparatus 1 selects “actress A”, “hotel B”, “movie C”, “TV program E”, or “sunglasses” from the text included in the first content C11 in the selection process of step S2. It is possible to extract a word such as “G” and specify one or more words that are likely to be searched among these words as a search keyword.

  For example, the information providing apparatus 1 can determine “actress A” as a search keyword when the word “actress A” is most likely to be searched among the words included in the first content C11. In addition, the information providing apparatus 1 selects “actress A movie C” when there is a high possibility that the word “movie C” among the words included in the first content C11 will be retrieved together with the word “actress A”. It can also be determined as a search keyword.

  The information providing apparatus 1 can also determine the search keyword in advance for each content. In this case, the process of step S2 is performed before the content is requested from the terminal device 2. The information providing device 1 can also determine the search keyword based on the user U of the terminal device 2. In addition, the information providing apparatus 1 determines, as the search keyword, a search keyword that is frequently used by another user who has browsed the first content C11 in the past while browsing the first content C11 or immediately after the browsing. be able to.

  The terminal device 2 performs an acquisition process of acquiring the first content C11 and the search target information provided from the information providing device 1 (step S5). Then, the terminal device 2 performs a display process of displaying the first content C11 acquired from the information providing device 1 on the screen 80 of the display unit 33 (step S6). As a result, the screen 80 of the display unit 33 is in the first state shown in FIG. On the screen 80 in the first state, the search content C30 is displayed together with the first content C11. A search window C31 for inputting a search keyword and a search button C32 for transmitting a search query including the search keyword input in the search window C31 to a search server (not shown) are arranged in the search content C30.

  After that, when the user U scrolls the first content C11 by the scroll operation, the terminal device 2 changes the area of the first content C11 displayed on the screen 80, like the screen 80 in the second state shown in FIG. Change (step S7).

  Then, when the user U further scrolls, the terminal device 2 further moves the first content C11 from the screen 80 in the second state shown in FIG. 1 to display the screen 80 in the third state shown in FIG. Then, the first content C11 is moved to the outside of the screen 80 of the display unit 33. When the first content C11 is outside the screen 80 of the display unit 33, the terminal device 2 causes the search keyword C to be input to the search window C31 of the search content C30 based on the search target information acquired from the information providing device 1. The state is displayed on the display unit 33 (step S8). On the screen 80 in the third state shown in FIG. 1, a search window C31 in which the text “actress A movie C”, which is the text related to the first content C11, is input as a search keyword is displayed.

  In the example described above, the terminal device 2 displays the search keyword on the display unit 33 when the entire first content C11 is off the screen 80 of the display unit 33. When a part of the first content C11 is outside the screen 80 of the display unit 33, the search keyword can be displayed on the display unit 33. This is because, for example, the user U may have finished browsing the first content C11 even when the entire first content C11 does not go out of the screen 80 of the display unit 33. This is because the user U may want to search while browsing one content C11.

  In this way, the terminal device 2 searches for content related to the first content C11 when part or all of the first content C11 is outside the screen 80 of the display unit 33 due to the scroll operation of the user U. A search window C31 in which a search keyword for input is input is displayed on the display unit 33. Therefore, when the user U who is browsing or has finished browsing the first content C11 wants to search for content related to the first content C11, it is possible to save the trouble of inputting the search keyword in the search window C31.

  When the user U who has browsed the first content C11 operates the return button 81 to return to the previous display content on the screen 80 in the third state, the terminal device 2 operates as the information providing device. Based on the search target information acquired from No. 1, the search window C31 in which the search keyword for searching the content related to the browsed first content C11 is input is displayed (step S9).

  For example, as in the third state shown in FIG. 1, when the user U operates the return button 81 after browsing the first content C11, the screen 80 of the display unit 33 displays the screen in the fourth state shown in FIG.

  As described above, the terminal device 2 displays the search window C31 in a state in which the search keyword for searching the content related to the first content C11 that the user U has finished browsing, into the plurality of second content C21, It can be displayed on the screen 80 on which C22, C23 and C24 are displayed. Therefore, when the user U who has browsed the first content C11 wants to search for the content related to the first content C11, it is possible to save the trouble of inputting the search keyword in the search window C31. Further, the user U can perform the search without re-viewing the first content C11. The screen 80 in the fourth state is, for example, a top page screen for displaying the content provided by the information providing apparatus 1, and is also called a home screen.

  Similarly, when the user U operates the return button 81 on the screen 80 in the second state shown in FIG. 1, the terminal device 2 similarly inputs the search keyword for searching the content related to the first content C11. The state search window C31 may be displayed on the screen 80 on which the plurality of second contents C21, C22, C23, C24 are displayed.

  The second content C21 includes link information for transitioning to the first content C11, and the terminal device 2 displays the first content C11 when the second content C21 is selected. To display. Similarly, the second content C22 includes link information for making a transition to the first content C12 (not shown), and the second content C23 makes a transition to the first content C13 (not shown). Contains link information for.

  Further, the search target information may include a plurality of search keywords including one or more words or character strings. In this case, the terminal device 2 can switch the search keyword input into the search window C31 from a plurality of search keywords included in the search target information based on a predetermined condition.

  For example, the terminal device 2 can switch the search keyword input to the search window C31 every predetermined time. In addition, the terminal device 2 has a browsing speed (for example, a scroll speed) and a browsing time (for example, a scrolling speed) of the first content C11 by the user U and a time period from the start of the display of the first content C11 to the operation of the return button 81. It is also possible to select a search keyword according to () from a plurality of search keywords.

  In the example described above, the terminal device 2 displays one search window C31 when displaying the first content C11, but it is also possible to display a plurality of search windows C31. In this case, the terminal device 2 can display each of the plurality of mutually different search keywords in the corresponding search window C31 among the plurality of search windows C31.

  In the example described above, the terminal device 2 enters the search keyword in the search window C31 of the search content C30 fixed at the uppermost position of the screen 80, but at the end position of the area of the first content C11. Search content different from the search content C30 may be arranged at the subsequent position.

  Further, when the amount of text included in the first content C11 is large, the information providing device 1 divides the text included in the first content C11, and a search keyword for each divided text (hereinafter, referred to as divided text). Can also be determined. In this case, when some or all of the divided texts are outside the screen 80, the terminal device 2 brings the search keyword for searching the content related to the divided texts into the search window C31. You can also

  Further, when the reception unit 22 receives a distribution request for the first content C10 from the terminal device 2, the selection unit 23 selects the first content C10 to be distributed (hereinafter, may be referred to as target content). The information is analyzed and the information satisfying a predetermined condition is specified. For example, the selection unit 23 analyzes the target content and calculates the possibility (hereinafter referred to as search possibility) that a web search is performed using each piece of information included in the target content as a search keyword.

  For example, the selection unit 23 extracts a word included in the target content by using a technique such as morphological analysis. Then, the selection unit 23 can perform a search for each extracted word (hereinafter referred to as an extracted word) based on information included in the search log database 14 and the user information database 15 stored in the storage unit 12. Calculate the sex.

  For example, the selection unit 23 sets the number of times the web search is performed using the extracted word as the search keyword, the date and time when the web search is performed, the number of times the target content appears, and the word related to the extracted word as the search keyword. The search possibility is calculated for each extracted word based on the number of times the web search is performed, the attribute of the user U, the action history, and the like. For example, based on the search log database 14, the selection unit 23 can increase the value of the search possibility as the extracted word having the higher number of web searches.

  Further, for example, in contents such as news, the positions where important words are arranged tend to be biased. Therefore, the selection unit 23 determines which of the target contents includes whether the extracted word is included in the title, whether it is included in the title and the main portion, and whether the extracted word is included in the same paragraph multiple times. The search possibility can be calculated depending on whether the extracted word is arranged at the position.

  Further, it is predicted that the position where the important word is arranged is different between the case where the content is sports-related content and the case where the content is entertainment-related content. Therefore, the selection unit 23 can calculate the search possibility according to the attribute of the target content and the position where the extracted word is arranged. That is, the selection unit 23 can calculate the search possibility according to the importance of the position where the extracted word is arranged.

  In addition, the selection unit 23 can calculate the search possibility based on whether or not the content of the target content is related to each extracted word. Further, the selection unit 23 can calculate the search possibility based on the number of times each extracted word appears in the target content.

  Further, the selection unit 23 can calculate the search possibility based on whether or not each extracted word is a so-called buzz word. For example, the selection unit 23 can calculate the search possibility based on the increase in the number of times the web search is performed using each extracted word as a search keyword per unit time. Further, the selection unit 23 can calculate the searchability based on the number of postings including each extracted word on an SNS (Social Networking Service), a microblog, or the like. Further, the selection unit 23 can correct the search possibility by considering whether the extracted word is an exclusion word that is not used as a search keyword, whether it is an essential word that is used as a search keyword, or the like.

  In addition, the selection unit 23, for example, a search used in a web search when a plurality of users U who have browsed the target content in the past browse the target content (for example, during browsing or immediately after browsing. The same applies below). Keywords can be specified. Then, the selection unit 23 selects the value of the search possibility such as the extracted word that is the same as the word included in the specified search keyword or the extracted word that is highly related to the specified search keyword in the information included in the target content. It can be higher.

  Further, the selection unit 23 can specify the search keyword used in the web search when the user U having the same attribute as the user U who browses the target content browses the target content. Then, the selection unit 23 can set the searchability value of the extracted word that is the same as the word included in the specified search keyword or the extracted word that is highly relevant to the information included in the target content to a higher value. it can.

  In addition, the selection unit 23 can search arbitrary information such as the search log, the position including the extracted word, the attribute of the target content, the attribute of the user U, and the action history of the user U as a feature (feature amount). The model for calculating the sex is learned for each word, and the possibility of web search can be calculated for each extracted word by using the learned model for each word.

  In this way, the selection unit 23 calculates the searchability of each extracted word based on arbitrary information such as the search log, the content of the target content, the type of the target content, the attribute of the user U and the action history.

  The selection unit 23 selects the information for displaying the search keyword in the search window from the information included in the target content to be distributed. For example, the selection unit 23 selects one or more words having the largest searchability value calculated for each word or a word larger than a predetermined threshold value. Then, the selection unit 23 generates one or more selected words (hereinafter, referred to as a selected word) as the first search information, and outputs the generated first search information to the providing unit 24.

  Also, the selection unit 23 divides the text included in the target content into two or more pieces based on a predetermined division condition, and for each divided text that is the divided text, a word having the largest searchability value or a predetermined value. A word larger than the threshold of can be selected as the selected word. The predetermined division conditions include, for example, the number of characters and the number of paragraphs. The selection unit 23 can divide the text included in the target content so that the number of characters or the number of paragraphs included in each divided text falls within a predetermined range.

  Further, the selection unit 23 extracts from the search log a word that has been frequently searched with the selected word, and selects a word included in the target content from the extracted words as the second search information. Then, the selection unit 23 outputs the selected second search information to the provision unit 24.

  The selection unit 23 is used, for example, by a plurality of users U who browsed the target content in the past together with the selected word among the plurality of words used in the web search together with the selected word when browsing the target content. One or more words having a large number of times can be specified as the second search information.

  The selection unit 23 can also select the second search information based on the attribute of the user U who performed the web search, the attribute of the user U who starts browsing the target content, and the like. For example, when a plurality of users U having the same attribute as the user U who browses the target content browses, the selection unit 23 uses the selected word together with the selected word among the plurality of words used in the web search. It is possible to select a word that has been frequently used as the second search information.

  When the text included in the target content is divided, the selection unit 23 can select one or more first search information and one or more second search information for each divided text.

  The providing unit 24 transmits the search target information including the one or more pieces of first search information and the one or more pieces of second search information selected by the selection unit 23 to the terminal device 2 via the network 3 together with the first content C10. To do. In addition, the selection unit 23 can also transmit the search target information including only the first search information that does not include the second search information to the terminal device 2.

  The selecting unit 23 can also select a search keyword as search target information without analyzing the text included in the target content. For example, the selection unit 23 uses the search keyword information most frequently used among the search keywords used by the plurality of users U who have browsed the target content in the past to browse the target content. Can be selected as the search target information. In addition, the selection unit 23 uses the search keyword most frequently used among the search keywords used for the search when a plurality of users U having the same attribute as the user U who browses the target content browses the target content. Can be selected as the information of the search target information.

Is input), the first content C10 and the search target information are acquired from the information providing apparatus 1 by transmitting a distribution request including the URL of the first content C10 to the information providing apparatus 1 to the information providing apparatus 1. In addition, when the display of the second content C20 is requested by the operation of the user U, the acquisition unit 42 acquires the second content C20 from the information providing device 1.

  In addition, when the search button C32 (see FIG. 1) is operated by the user U in a state where the search keyword is input into the search window C31 (see FIG. 1), the acquisition unit 42 inputs the search keyword into the search window C31. A search query including a search keyword that is present is transmitted to a search server (not shown). The acquisition unit 42 can acquire search result content (for example, web content indicating a search result such as a search result page) corresponding to the search query from the search server.

  The display processing unit 43 causes the display unit 33 to display the first content C10 and the second content C20 acquired from the information providing apparatus 1. In addition, when the display processing unit 43 displays the first content C10 on the display unit 33, the display processing unit 43 displays the search window C31 in which the search keyword is input based on the search target information acquired by the acquisition unit 42. 33 to display.

  7 to 9 are diagrams for explaining display processing in the terminal device according to the embodiment. 7 to 9, the first content C11 is shown as an example of the first content C10, but similar processing is performed on the first content C10 other than the first content C11.

  On the screen 80 in the first state shown in FIG. 7, the first content C11 is displayed. In this state, the end position (lower end position) of the first content C11 is not displayed. When the user U performs a scroll operation from the screen 80 in the first state, the display processing unit 43 causes the area of the first content C11 displayed on the screen 80 to be the same as the screen 80 in the second state shown in FIG. 7. Will be changed. In addition, on the screen 80 in the second state, next to the first content C11, the third content C50 including the text in which the link information to the content related to the first content C11 is set is displayed.

  When the display processing unit 43 determines that the first content C11 is outside the screen 80 by changing the display content of the screen 80 by the scroll operation of the user U from the screen 80 in the second state illustrated in FIG. 7, Like the screen 80 in the third state shown in FIG. 7, the search keyword “actress A movie C” is displayed on the display unit 33 while being input in the search window C31. As a result, the user U can save the trouble of inputting the search keyword in the search window C31 when he or she wants to search the content related to the first content C11 after the browsing of the first content C11 is completed.

  When the user U operates the search button C32 on the screen 80 in the third state shown in FIG. 7, the acquisition unit 42 executes the search query including the search keyword “actress A movie C” input in the search window C31. A search result content indicating a search result corresponding to the search keyword “actress A movie C” is transmitted to a search server (not shown) from the search server. The display processing unit 43 causes the display unit 33 to display the search result content acquired by the acquisition unit 42.

  In addition, when the user U operates the return button 81 on the screen 80 in the third state shown in FIG. 7, the display processing unit 43 is based on the search target information like the screen 80 in the fourth state shown in FIG. Then, the screen 80 in which the search content C40 including the search window C31 in which the search keyword "actress A movie C" is input by the first search information "actress A" and the second search information "movie C" is arranged is displayed. It is displayed on the section 33.

  When the user U operates the search button C42 on the screen 80 in the fourth state shown in FIG. 7, the acquisition unit 42 executes the search query including the search keyword “actress A movie C” input in the search window C31. It is transmitted to a search server (not shown), and the search result content indicating the search result corresponding to the search keyword “actress A movie C” is acquired. The display processing unit 43 causes the display unit 33 to display the search result content acquired by the acquisition unit 42. As a result, the user U can enter a search keyword in the search window C31 when he / she wants to search for content related to the first content C11 when the screen changes to another screen after the browsing of the first content C11 ends. It is possible to save the trouble of inputting.

  In the above-described example, the display processing unit 43 causes the display unit 33 to display the same search keyword entered in the search window C31 on the screen 80 in the third state and the screen 80 in the fourth state. It is also possible to display different search keywords on the screen 80 and the screen 80 in the fourth state in the search window C31 on the display unit 33.

  Further, when the user U operates the return button 81 on the screen 80 in the second state, the display processing unit 43, based on the first search information “actress A” included in the search target information, the search keyword “actress A”. It is also possible to display the screen 80 on which the search content C40 including the search window C31 in which “” has been input is arranged on the display unit 33. In this case, in the search window C31 on the screen 80 in the fourth state shown in FIG. 7, the search keyword “actress A” is input instead of the search keyword “actress A movie C”.

  As a result, for example, when it is assumed that the degree of browsing of the first content C11 by the user U is high (for example, the third state shown in FIG. 7), the first search information and the second search information are used. When it is assumed that a specific search is possible and the degree of browsing is low (for example, the second state shown in FIG. 7), it is possible to perform a general search using only the first search information. .

  The display processing unit 43 can cause the display unit 33 to display the search window C31 in a state in which the search keyword corresponding to the browsing situation of the user U is input by a process other than the above example. For example, the display processing unit 43 can change the search keyword to be input to the search window C31 according to the browsing time and the scroll speed of the first content C11 by the user U on the screen 80 in the third state.

  For example, when the viewing time of the first content C11 by the user U is less than the threshold value, the display processing unit 43 can display the first search information on the display unit 33 with the search window C31 input. Further, the display processing unit 43 displays the first search information and the second search information on the display unit 33 in a state of being input in the search window C31 when the browsing time of the first content C11 by the user U is equal to or more than the threshold value. Can be made. The browsing time of the first content C11 is, for example, the time from the start of the display of the first content C11 to the start of the display of the search window C31, or the display of the first content C11 and the return button. It is the time until 81 is operated.

  In addition, the display processing unit 43 inputs the first search information into the search window C31 when the scroll speed of the first content C11 by the user U is equal to or higher than the threshold value. In addition, when the scroll speed of the first content C11 by the user U is less than the threshold, the display processing unit 43 displays the first search information and the second search information on the display unit 33 with the search window C31 input. Can be made.

  Further, when the acquisition unit 42 acquires the search target information for each of the divided texts, the display processing unit 43 inputs the search keyword corresponding to the position of the divided texts in the search window C31 as shown in FIG. Can be displayed. In the example shown in FIG. 8, the first content C11 includes two divided texts C11A and C11B.

  Specifically, the display processing unit 43 causes the divided text C11A to be displayed outside the screen 80 as in the screen 80 in the second state shown in FIG. 8 by the scroll operation by the user U from the screen 80 in the first state shown in FIG. When it becomes, the search keyword corresponding to the divided text C11A is displayed on the display unit 33 in a state of being input in the search window C31.

  Thereafter, when the user U further scrolls the divided text C11B off the screen as in the screen 80 in the third state shown in FIG. 8, the display processing unit 43 displays the search keyword corresponding to the divided text C11B. It is displayed on the display unit 33 in the state of being input in the search window C31.

  In the above example, the example in which the text included in the first content C11 is divided into two has been described, but the display processing unit 43 divides the text included in the first content C11 into three or more, and The search keyword corresponding to the divided text can be displayed on the display unit 33 while being displayed in the search window C31. Further, the display processing unit 43 can also display the search keyword corresponding to the divided text in the search window C31 on the display unit 33 when a part of each divided text is outside the screen 80.

  In addition to the search window C31, the display processing unit 43 can also display a further search window on the display unit 33 at the end position of the first content C11 or a position within the first content C11. For example, when the user U scrolls from the screen 80 in the first state shown in FIG. 9, the ending position of the first content C11 is displayed. At this time, the display processing unit 43, as shown in the screen 80 in the second state of FIG. 9, based on the search target information, at the position following the end position of the first content C11, the search keyword “actress A movie C”. The search content C40 including the search window C41 in which is input can be displayed on the display unit 33.

  When the user U operates the search button C42 on the screen 80 in the second state in FIG. 9, the acquisition unit 42 fails to search for a search query including the search keyword “actress A movie C” input in the search window C31. The search result content is transmitted to the illustrated search server, and the search result content indicating the search result corresponding to the search keyword “actress A movie C” is acquired. The display processing unit 43 causes the display unit 33 to display the search result content acquired by the acquisition unit 42.

  Note that the display processing unit 43 may switch the search keyword input to the search window C31 at predetermined time intervals when different search keywords can be input to the search window C31 based on the search target information acquired by the acquisition unit 42. it can.

  Further, the display processing unit 43 can also switch the search keyword to be input to the search windows C31 and C41 according to the physical state of the terminal device 2 detected by the physical sensor 34. The physical state of the terminal device 2 is, for example, a state in which the terminal device 2 is shaken by the user U, a state in which the terminal device 2 is moving, an ambient temperature of the terminal device 2, or the like.

  In addition, the display processing unit 43 displays the first content C11 at the timing when the first content C10 is displayed on the display unit 33 or a predetermined time after the display of the first content C10 regardless of the scrolling operation of the user U. The related search keyword may be displayed on the display unit 33 while being displayed in the search window C31.
