  Hereinafter, preferred embodiments of a content display terminal, a content display system, and a content display method according to the present invention will be described with reference to the accompanying drawings.

  First, a content display system including a content display terminal in the embodiment will be described with reference to FIG. As shown in FIG. 1, the content display system 1 includes a content display terminal 10 and a content server 20. For example, a mobile terminal such as a smartphone corresponds to the content display terminal 10.

  The content display terminal 10 includes a call request transmission unit 11, a content reception unit 12, a score calculation unit 13, a content selection unit 14, a trigger condition determination unit 15, and a display unit 16. The content display terminal 10 includes a content storage unit 17 that stores content and a terminal-side information storage unit 18 that stores terminal-side information as storage units. The terminal-side information includes user information regarding the user who owns the content display terminal 10 and current status information regarding the current status of the content display terminal 10.

  The user information included in the terminal-side information includes user profile data and user action history data. The user profile data includes, for example, an address, gender, age, occupation, workplace location, annual income, lifestyle, interest category, and the like. The action history data includes, for example, a history of content set by the user to OK / NG (no good), a history of content that the user has reacted to, a history of content that the user has not responded to, an Internet reference history, and a call destination history. , Current position history and the like are included. Note that the evaluation of the content set by the user is not limited to the two stages of OK / NG, and can be set in multiple stages.

  The current status information included in the terminal-side information includes, for example, context data such as the current position (latitude and longitude), the current position type (home, work, etc.), the current date and time, and the current terminal usage status. The current terminal usage status includes an application startup status (hereinafter referred to as “application”), a call status, a mail usage status, an Internet reference status, and the like.

  The call request transmission unit 11 transmits a call request including the content corresponding to the search keyword item to the content server 20 when the state of the terminal matches the call timing condition. Here, the call timing condition and the search keyword item are collectively managed as rule information on the content server 20 side. The content display terminal 10 periodically accesses the server to check the update status of the rule information, and fetches the latest rule information into the own terminal according to the update status.

  The calling timing conditions can be set using terminal-side information such as the usage frequency of the content display terminal 10, the current position of the content display terminal 10, the address of the user who owns the content display terminal 10, and the current time, for example. it can. Specifically, the condition that “the terminal usage frequency of the user is 10 times or more and the current location of the terminal is Roppongi”, the condition that “the current location of the terminal has moved to Ginza”, and “the address is A condition such as “Tokyo and 10:00 am every morning” can be set. As the terminal usage frequency, for example, the number of times that a specific or unspecified application is activated can be used.

  By including the usage frequency of the content display terminal 10 and the current position of the content display terminal 10 in the call timing condition, when the content display terminal 10 having a high usage frequency moves to a specific region, the content display terminal 10 On the other hand, content suitable for the user of the content display terminal 10 can be provided.

  The search keyword item is configured with an item that can distinguish whether the content is provided as a destination. For example, the search keyword item can be set using terminal-side information such as the usage frequency of the content display terminal 10 and the address, sex, and age of the user who owns the content display terminal 10. Specifically, “daily terminal usage frequency”, “address”, “gender”, and “age” can be set as search keyword items. In this case, for example, the data “high”, “Roppongi”, “male”, and “30's” are included in the call request as the contents corresponding to the search keyword item.

  By configuring the search keyword item with an item that can be discriminated as to whether the content is to be provided, content related to the content corresponding to the search keyword item is provided to the content display terminal 10 suitable as the content supply destination. It becomes possible.

  The content receiver 12 receives the content transmitted from the content server 20 in response to the call request. Here, the data structure of the content will be described. In addition to content data, content includes various data such as content ID, target service area ID, target application ID, target device ID, provision destination narrowing information, provision destination exclusion condition, trigger condition, registration date, validity period, and the like. It has been added.

  The content ID is identification information for uniquely identifying the content, and the target service area ID is identification information for uniquely identifying the service area designated as the content provision target. The target application ID is identification information for uniquely identifying an application designated as a content provision target, and the target device ID is identification information for uniquely identifying a device as a provision target designated as a content provision target.

  The provision destination narrowing information is information for narrowing the content provision destination to the provision destination desired by the provider, and is generated using the terminal side information. The provision destination exclusion condition is a condition for excluding from the content provision destination, and is specified using the terminal-side information.

  The trigger condition is a condition for causing the content terminal to display the content when the content terminal shifts to a situation suitable for providing the content. The trigger condition is specified using, for example, a position, day of the week, date and time, URL (uniform resource locator), mail address, telephone number, application ID (application identification information), terminal operation content, and the like. In this case, the content is displayed when moving to the specified position, day of the week or date and time, and the content is displayed when a communication / call is made to the specified URL, e-mail address or telephone number, and the specified application is activated. The content is displayed when the terminal is operated, and the content is displayed when the designated terminal operation is performed.

  The trigger condition may be specified by arbitrarily combining position, day of the week, date / time, URL, mail address, telephone number, application ID, and terminal operation content, or position, day of the week, date / time, URL, mail address, telephone. You may specify using any one of a number, application ID, or terminal operation content.

  By including any of the position, day of the week, and date / time in the trigger condition, when the position, day of the week or date / time intended by the content provider is reached, the content display terminal 10 displays content appropriate for the position, day of the week or date / time. It becomes possible to make it.

  Also, by including any of URL, e-mail address or telephone number in the trigger condition, when communication / call is made to the destination intended by the content provider, it is suitable for the URL, e-mail address or telephone number. The content can be displayed on the content display terminal 10.

  In addition, by including the application ID in the trigger condition, when an application intended by the content provider is activated, it is possible to display content appropriate for the application on the content display terminal 10.

  In addition, by including the terminal operation content in the trigger condition, it is possible to display content suitable for the terminal operation on the content display terminal 10 when the terminal operation intended by the content provider is performed.

  The registration date is information indicating a date when the content is registered in the content server 20, and the valid period is information indicating a period (starting from the registration date) in which the content is valid.

  The score calculation unit 13 compares the provision destination narrowing information added to each content with the terminal side information stored in the terminal side information storage unit 18 to calculate the score of each content. The content for which the score is to be calculated are the content received by the content receiving unit 12 and the content already stored in the content storage unit 17.

  Specifically, the score calculation unit 13 compares corresponding data items of the provision destination narrowing information and the terminal side information, and has a high degree of matching (similarity) between the provision destination narrowing information and the terminal side information. The content score is calculated so that the score becomes higher. The degree of matching between the provision destination narrowing information and the terminal side information can be calculated by using various known methods such as fuzzy theory, clustering, SVM (support vector machine), and complex network.

  The score calculation unit 13 may adjust the score using the action history data included in the terminal-side information when calculating the content score. For example, it is good also as referring the action history data with respect to content, and deducting the score of the content with high possibility that a user does not like.

  The content selection unit 14 uses the score calculated by the score calculation unit 13 to select content to be stored in the content storage unit 17. Specifically, the content selection unit 14 sorts the content after the score calculation in descending order of the score, and selects a predetermined number of content from the higher score. The predetermined number can be set as appropriate in consideration of the storage capacity and processing capacity of the content display terminal 10.

  The content selection unit 14 can exclude content that meets a predetermined condition from selection targets. Examples of content that conforms to the predetermined condition include content to which a provision destination exclusion condition that conforms to terminal-side information is added, content that can be determined to have a low evaluation by the user, content that has a score less than a threshold, and the like . Examples of content that can be determined to be low by the user include, for example, content set by the user as NG in the action history data, content that the user did not react in the action history data, and Internet reference history of the action history data Among the content that matches the reference destination included in the content, content that has been referred to within the past predetermined number of days is included.

  In this way, by excluding content that meets the predetermined condition from the selection target, it is possible to exclude the content display terminal 10 that is not suitable as the content providing destination from the content providing destination, or content that the user is likely not to like Can be excluded from the display target.

  The trigger condition determination unit 15 compares the trigger condition added to the content stored in the content storage unit 17 with the current state information stored in the terminal-side information storage unit 18 and uses the current state information as the trigger condition. Determine if it matches.

  The display unit 16 displays on the screen the content having the trigger condition determined by the trigger condition determination unit 15 to match the terminal current status information. In addition, what is necessary is just to display the information regarding a content on a screen. Therefore, the content itself may be displayed, or information that can reach the content, such as a hyperlink, may be displayed.

  The content server 20 includes a call request reception unit 21, a content search unit 22, a score calculation unit 23, a content selection unit 24, and a content transmission unit 25.

  The call request receiving unit 21 receives a call request transmitted from the content display terminal 10.

  The content search unit 22 searches the content storage unit 26 using the content of the search keyword item included in the call request, and extracts content related to the content of the search keyword item.

  The score calculation unit 23 compares the provided destination narrowing information added to each extracted content with the content of the search keyword item (terminal side information) included in the call request, and calculates the score of each content. The content score can be calculated in the same manner as the score calculation unit 13 of the content display terminal 10.

  The content selection unit 24 selects content to be transmitted to the content display terminal 10 using the score calculated by the score calculation unit 23. Specifically, the content selection unit 24 sorts the content after the score calculation in descending order of the score, and selects a predetermined number of content from the higher score. The predetermined number can be set as appropriate in consideration of the communication bandwidth and communication speed of the network, the storage capacity and processing capability of the content display terminal 10, and the like.

  The content selection unit 24 can exclude content that satisfies a predetermined condition from selection targets. For example, content registered on a past date corresponds to the content that satisfies the predetermined condition. This is to exclude content that has already been transmitted from the transmission target. Therefore, if duplicate transmission can be prevented, it may be excluded by another method. For example, for each content, the ID of the content display terminal that transmitted the content may be registered and managed, and the content for which the ID of the content display terminal corresponding to the call request has already been registered may be excluded from selection targets. .

  The content transmission unit 25 compresses the content selected by the content selection unit 24 and transmits it to the content display terminal 10 corresponding to the call request. When compressing content, it is desirable to compress lossless data such as text data and losslessly compress relatively large data such as moving images, still images, and music data.

  Next, with reference to FIG. 2, the operation when the content display terminal 10 acquires and stores content from the content server 20 will be described.
