Abstract

PROBLEM TO BE SOLVED: To accelerate communication that a user expect by enabling a user to accurately determine reliability of information that various users have officially announced.SOLUTION: An information providing server which communicates with users through a network includes: a reception part which receives a signal including a retrieval keyword; a storage part which stores individual history information representing action histories of a plurality of respective users; a retrieval part which retrieves action history information representing the action history related to a retrieval keyword from the individual history information; a calculation part which calculates points of each of the plurality of users using the action history information; and a transmission part which transmits through the network a signal including presentation information needed to present information on the users according to the points of each of the plurality of users to the user having sent the retrieval keyword.

Description

  The present invention relates to an information providing server and an information providing method.

  With the development of information communication means, users can form a broad community by exchanging information with other users directly or indirectly. An example of such a prior art is described in Patent Document 1. In Patent Document 1, direct communication between users is performed mainly based on the user's name, but more complicated information may be communicated via a network. For example, a user who is a searcher transmits a search keyword to an information providing server via a network, and the information providing server notifies the searcher of a user who includes the search keyword in the self-introduction sentence. It is done.

  FIG. 1 shows an example of a search result displayed on such a searcher's communication terminal. In the case of the illustrated example, the searcher transmits the search keyword “cooking” to the information providing server, and the information providing server identifies the user (A, B, C) including “cooking” in the self-introduction sentence Notify searchers. In the case of FIG. 1, users A, B, and C are displayed on the searcher's communication terminal together with their own self-introduction sentences.

  In general, a user's self-introduction sentence or profile is registered and published as it is after the user writes it. This has the advantage that the user can publish his / her information widely and freely, but has the disadvantage that the credibility or reliability of the self-introduction is not always high. Rather, there is a concern that the content represented by the self-introduction sentence does not match the actual action content of the user. It is not in line with the searcher's intention that the searcher is notified of information about the user whose behavioral content does not match the self-introduction sentence, and the system prompts the user to exchange information with the searcher. Furthermore, there is a concern that the reliability of the information providing system that introduces a user who is not accompanied by an actual action to the searcher may also be lowered.

  According to one embodiment, the information providing server searches for action history information indicating a history of actions related to the search keyword from personal history information indicating the action history of each of a plurality of users. The information providing server uses the action history information to calculate a score for each of a plurality of users, and uses a search keyword as a search keyword to include a presentation information necessary for presenting the user information according to the score. Send to the sending user. The score is calculated not based on the user's self-introduction sentence but on the action history information indicating the actual action history of the user. A user with a high score is very interested or familiar with the matter to be searched. The user who requested the search can promote the communication expected by the user by exchanging information with the user having a high score.

<1. Communication system>
FIG. 2 shows an outline of a communication system used in the embodiment. The communication system includes at least a communication terminal 10, a communication network 20, an Internet network 30, an information providing server 40, a store information server 50, a social network service (SNS) 60, and an RSS 70. The communication terminal 10 may be any appropriate communication terminal capable of communicating information via the communication network 20 and the Internet network 30.

  The communication terminal is typically a mobile terminal, but may be a fixed terminal. Specific examples of the communication terminal include, but are not limited to, a mobile phone, an information terminal, a smartphone, a notebook personal computer, a laptop computer, and a desktop computer.

  The communication network 20 may be any appropriate communication network that enables communication between the communication terminal 10 and the information providing server 30. The communication network 20 is typically a mobile communication network, but may be any appropriate communication network that is wireless or wired. As an example, the communication network 20 is a security network capable of safely communicating secret information. Generally, the security of the Internet network 30 is low, but communication over a wide range is possible. It is not essential for the present invention that the communication network 20 and the Internet network 30 are provided as illustrated, and one of them may be omitted depending on circumstances.

  The information providing server 40 is connected to communication terminals of various users, manages information of various users, and provides a search service according to the present embodiment. Specific contents of the search service will be described later. The user information includes information indicating the user's behavior history (personal history information, behavior history information), information indicating the history of the user operating the communication terminal (usage history information), and the like.

  The store information server 50 provides information on stores that deal with products or services (services) as necessary. The store information includes store contact information (telephone number, e-mail address, etc.), site address, geographical address, store description, and the like. Specifically, information on stores such as retail stores, restaurants, movie theaters, and travel agencies is provided to an information providing server or the like.

  Social network service (SNS) 60 provides a community-type site that supports connections between people. In general, a user can send information such as opinions, impressions, and questions about a certain matter. By browsing information transmitted by other users, information exchange between users is promoted.

RSS (R eally Simple Syndication S ite S ummary) 70 , for the site specified by the user, provides a service that notifies the updating information indicating that an update to the user. For example, it is assumed that a user has a contract for subscribing to international news from a certain site, and the user has registered that site with RSS70. When the information provided by the site is updated, the RSS 70 notifies the user of update information indicating that the site has been updated. The update information describes, for example, a title, a headline, a summary, an update time, and the like. The user who has received the notification of the update information can access the contracted site and know the details of the news as necessary.

<2. Example of operation>
Hereinafter, an operation example according to the embodiment will be described. For convenience, an operation example will be described separately for an operation for storing information and an operation for providing a search service using the stored information.

<< 2.1 Information Storage >>
FIG. 3 shows a sequence when the information providing server accumulates history information (or personal history information) representing a user's action history in the communication system as shown in FIG. The history information indicates a history that the user has taken some action using the communication terminal 10. “Behavior history information” to be described later is information related to a specific search keyword in the history information. The information accumulated as history information includes searching for stores, etc., registering contact information of stores, etc. in the phone book, using social network services (SNS) (especially sending information), Received updated information provided for the theme, made a call or sent information to a contact registered in the phone book, and visited the contact location registered in the phone book Including, but not limited to, one or more of making payments using the communication terminal 10.

  In steps S301 and S303, the communication terminal 10 transmits a search request for searching for a store to the store information server via the information providing server 40. The search keyword may be manually input by the user, or may be selected from a menu listing options. For example, in order to search for a Chinese restaurant (restaurant), a search keyword such as “Chinese food” is transmitted. In response to this, the store information server 50 searches for stores related to “Chinese cuisine”.

  In steps S305 and S307, the store information server 50 transmits the search result searched based on the search keyword to the communication terminal 10 via the information providing server 40. As an example, the search result indicates a list of restaurants that provide “Chinese cuisine”.

  The information providing server 40 accumulates information indicating that the user of the communication terminal 10 has transmitted a search request using “Chinese cuisine” as a search keyword and acquired a search result as history information of the user. The timing of accumulating history information may be promptly performed after the information providing server 40 receives a search request from the communication terminal 10 in step S301 or after receiving a search result in step S305.

  Alternatively, the history information may be accumulated after acquiring the usage history information of the communication terminal 10 from the communication terminal 10 in step S309. The usage history information is created by the communication terminal itself and notified to the information providing server 40, whereas the above history information is created by the information providing server 40 creating the history information of the communication terminal 10. So they are not the same. However, the usage history information and the history information (or personal history information) include the same information, and the usage history information may be referred to as history information as long as there is no risk of confusion. The history information notified to the information providing server 40 by the communication terminal 10 in step S309 is not only that the search is performed and the search result is acquired, but also the contact information of any store from the search result is stored in the phone book. It may also include other information such as registration.

  The fact that the user has performed a search by specifying a certain search keyword, that the search result has been acquired, that the contact in the search result has been registered in the phone book, etc., is actually performed by the user regarding the search keyword. Action. Such an action is a measure of the user's interest or familiarity with the matter indicated by the search keyword. In the present embodiment, such information related to actual behavior is accumulated in the information providing server 40 as behavior history information. As a result, it is possible to distinguish between a user who has actually acted on the matter of the search keyword and a user who simply describes the matter in the self-introduction sentence.

  As described above, the history information indicating the action history is not limited to the store search, and various actions can be considered. As an example, a case where SNS 60 is used and a case where RSS 70 is used will be described. However, the present embodiment is not limited to these cases, and can be widely applied to information representing user behavior.

  In steps S311 and S313, the user transmits a posting request to the social network service (SNS) site via the information providing server 40. The posting request is a request for the user to send information such as an opinion, an impression, and a question about a certain matter. In this case, the user is actually taking action on some matter. Such behavior is a measure of an interest in something. The information providing server 40 accumulates as history information that the user has transmitted information about a certain matter.

  In steps S315 and S317, the user transmits a registration request for receiving update information of a predetermined site to the RSS server via the information providing server 40.

  In steps S319 and S321, the RSS server notifies the user of update information about the site designated by the user via the information providing server 40. In this case, the user is highly likely to actually perform an action of looking through information provided by the designated site. Such behavior is a measure of familiarity with the information provided by the site. The information providing server 40 accumulates as history information that the user has received update information for the information provided by the site specified by the user.

  In the above description, when the information providing server 40 exchanges information with the various servers (the store information server 50, the SNS 60, and the RSS 70) so that the information providing server 40 can acquire historical information related to the user's behavior, the information providing server 40 I was mediating. However, the present embodiment is not limited to such a form, and the information providing server 40 may not mediate the exchange.

  For example, as shown in step S331, the communication terminal 10 may directly transmit a store search request to the store information server 50 without going through the information providing server 40. As for the search result, as shown in step S333, the store information server 50 may directly transmit to the communication terminal 10 without going through the information providing server 40. Further, as shown in step S335, the communication terminal 10 may directly send the posting request to the SNS 60 without going through the information providing server 40. Furthermore, as shown in step S337, the RSS 70 may directly transmit update information to the communication terminal 10 without going through the information providing server 40. However, in order to enable the information providing server 40 to accumulate history information, the communication terminal 10 notifies the information providing server 40 of the history information periodically or as needed, as shown in step S339. There is a need.

<< 2.2 Service Provision >>
FIG. 4 shows a sequence example when a search service is provided using information accumulated by performing the operation shown in FIG. The illustrated operation example is performed between the communication terminal 10 and the information providing server 40. The communication terminal 10 includes at least a search condition input unit 107 and a display unit 111. The information providing server 40 includes at least a search unit 404, a score calculation unit 405, and a storage unit 403. These and other processing units provided in the communication terminal 10 and the information providing server 40 will be described later.

  In step S401, the communication terminal 10 transmits a signal including the search keyword input by the user through the search condition input unit 107 to the information providing server 40. A signal including a search keyword represents a search request that requests to search for a user who is interested or familiar with the matter indicated by the search keyword. The search keyword may be manually input by the user by the search condition input unit 107 or may be selected from a menu listing options. As an example, it is assumed that the user designates a search keyword “cooking” for the purpose of exchanging information about cooking.

  In step S403, the information providing server 40 receives the signal including the search keyword, and in step S405, the search unit 404 searches the history information stored in the storage unit 403 using the search keyword “dishes”. . The storage unit 403 stores the history information described with reference to FIG. 3 for each user. For the convenience of explanation, the history information indicating the user's action history includes the number of times of sending information in the social network service (SNS) (number of postings), the number of times the address of the store or the like is registered in the phone book (number of address registrations) ) And the number of times update information has been received from the RSS server (number of RSS subscriptions). However, the history information may indicate other contents instead of or in addition to these. For example, the history information includes the number of times a store has been searched, the number of times a call or information has been sent to a contact registered in the phone book, the number of visits to a contact location registered in the phone book, a communication terminal The number of payments using 10 may be shown, but is not limited thereto.

  FIG. 5 schematically shows how history information is searched based on search keywords. FIG. 5 shows history information 51, 53, and 55 of a single user X. The history information of the user X includes at least post-related information 51, address registration information 53, and RSS subscription information 55.

  The post information 51 includes at least a post date and post content. By determining whether or not the posted content is related to the search keyword “cooking”, the number of postings related to “cooking” is derived. Whether the posted content is related to “cooking” may be determined by text analysis of the posted content. For example, a determination is made based on whether or not a predetermined number or more of “cooking” and other words similar to “cooking” (such as cooking, eating and drinking, kaiseki, and Chinese) are included in the posted content. Also good. In the case of the illustrated example, the number of postings is 10 times.

  Information 53 relating to address registration includes the name of the contact and a description of the contact. By determining whether or not these contact names and descriptions are related to the search keyword “cooking”, the number of times the address relating to “cooking” is registered is derived. Whether the name or description is related to “cooking” may be determined by text analysis of the name and description. For example, the determination is made based on whether or not a predetermined number or more of the names and explanations include “cooking” and other words similar to “cooking” (for example, cooking, eating and drinking, kaiseki, Chinese, etc.). It may be broken. In the case of the illustrated example, the number of address registrations is eight.

  Information 55 about the RSS subscription includes a category and a specific name. Whether or not these category names and the names of information distributed as the categories are related to the search keyword “dish”, whether the RSS subscription registered by the user is related to “dish” I understand. The number of times the user has received the update information is derived from the RSS subscription related to “cooking”. Whether the category name or information name is related to “cooking” may be determined by text analysis of the category name and information name. For example, the determination is based on whether or not “cooking” and other words similar to “cooking” (for example, cooking, eating and drinking, kaiseki, Chinese, etc.) are included in the category name and the information name by a predetermined number or more. May be performed. In the case of the illustrated example, the number of times update information is received by RSS subscription is four. Since the category is determined independently by the provider that provides the information, generally, the category classification and the name are different for each provider. Therefore, not only “cooking” but also other words similar to “cooking” (for example, cooking, eating and drinking, kaiseki, Chinese etc.) are used for text analysis, and RSS subscriptions about “cooking” are made. It can be appropriately determined whether or not.

  In this way, information related to the search keyword “dishes” is extracted from the history information of the user X. The extracted information is referred to as “behavior history information” in order to distinguish it from general “history information”. As shown in the figure, the action history information 57 regarding “cooking” of the user X includes information of the number of postings = 10, the number of address registrations = 8, and the number of RSS subscriptions = 4.

  In step 405 of FIG. 4, when the search unit 404 acquires the action history information of each user, they are notified to the score calculation unit 405 in step S407.

  In step S409, the score calculation unit 405 calculates each user's score from each user's action history information. The score calculation may be performed using any suitable method. For example, a user's score may be calculated by multiplying a numerical value or the number of times included in a user's action history information by a predetermined score.

In the case of the example shown in FIG. 5, points are determined in advance for each of the information items for posting, address registration, and RSS subscription. As an example, as shown in the table 59, the score is 3 points for posting, 2 points for address registration, and 1 point for RSS subscription. As will be described in a modification of the embodiment, the points set for each information item may be different depending on the contents of the search. The numerical value of the scoring is not limited to the illustrated example, but it is preferable to set according to the degree of interest and familiarity with the matter indicated by the search keyword. The RSS subscription is set to the lowest score because it only indicates that the user is receiving information about the dish. The address registration indicates that the user is more interested than the RSS subscription in that the user selects and registers by himself / herself. Therefore, a higher scoring is set than for RSS subscriptions. Furthermore, posting is the more aggressive act, so the highest score is set. The user's score is calculated based on such a score table. The user score in the example shown is
Posting times x 3 + address registration times x 2 + RSS subscription times x 1 = 10 x 3 + 8 x 2 + 4 x 1 = 50 points. Similarly, for other users, action history information is extracted from the history information, and a score is calculated.

  In step S411 of FIG. 4, the calculation result by the score calculation unit 405 is notified to the search unit 404.

  In step S413, the information providing server 40 notifies the user of the search result based on the calculation result.

  In step S415, the communication terminal 10 displays the users together with the action history information in descending order of the score.

  FIG. 6 shows a display example on the display unit 111 of the communication terminal 10 in step S415. Information of the top four users B, A, D, and C is displayed along with the action history information in the order of score. User D is in third place even though he has not posted a self-introduction. This is because the action of user D strongly indicates that he is interested in cooking. If users are simply listed based on the self-introduction sentence, it will be as shown in FIG. On the other hand, when the user's own action history is taken into consideration, rearrangement is performed as shown in FIG. Therefore, when it is desired to exchange information related to “cooking”, it can be easily and accurately determined that the user B, the user A, and the like are promising.

  Thereafter, based on the search result, the user exchanges information with the users B and A. The user may exchange information directly with the users B and A, or may exchange information indirectly via the information providing server 40.

  The display in FIG. 6 is merely an example of a specific display, and any other appropriate display may be performed. For example, one or more of the information items of the action history information may be omitted, or all may be omitted. In any case, it is only necessary that users who are candidates for information exchange are arranged in the order of scores.

  When the display as shown in FIG. 6 is performed, the information providing server 40 may provide the communication terminal with the user information rearranged in the score order, or the communication terminal arranges the users according to the score. You may change. In any case, the information providing server transmits information necessary for displaying the users according to the scores of the plurality of users to the communication terminal.

  By providing the search service in this way, a user who has requested a search for “dish” can easily and accurately determine a promising user as an information exchange partner.

FIG. 8 shows a functional block diagram of the information providing server. FIG. 8 shows various functional elements or processing units included in the information providing server, which are particularly related to the present embodiment. The illustrated information providing server can be used as the information providing server 40 shown in FIG. FIG. 8 shows a store information acquisition unit 401, a storage unit 403, a search unit 405, a score calculation unit 407, and a communication unit 409.

  The store information acquisition unit 401 acquires information about stores from a store information server (for example, the store information server 50 in FIG. 2). The information related to the store is typically a list of stores related to the search keyword specified by the user. In addition, information such as a store contact information, a site address, a location, and an explanatory note may be included in the information about the store.

  The storage unit 403 stores history information (or personal history information) indicating a user's action history. As described above, the history information may include various information items. In the illustrated example, the information stored in the storage unit 403 is information related to posting (post information), information related to address registration (address registration information), information related to RSS subscription, and other information. The other information includes, for example, personal information of the user, usage history information of the communication terminal, and the like.

  The search unit 405 extracts action history information related to the search keyword from history information (or personal history information) of various users based on the search keyword specified by the user.

  The communication unit 409 performs processing for communicating with the communication terminal 10.

<5. Modification>
<< 5.1 First Modification >>
As described above, the points set for each information item in the history information may always be the same or may differ depending on the content of the search. For example, eating a dish and making a dish are both related to cooking, but the actions that should be emphasized are different. A user who is interested in eating food is expected to register many addresses of various restaurants in the communication terminal. On the other hand, in the case of a user who is interested in cooking, the addresses of many restaurants are not necessarily registered in the communication terminal, but rather the addresses of restaurants are registered. It may not be an indication of your interest in creating. From this point of view, it is conceivable that the score of the information item of the number of registered addresses is set high for a search related to eating, and set low for a search related to cooking. . In addition, users who are familiar with cooking are expected to actively transmit information such as “how to” how to make food. From this point of view, it is conceivable that the score of the information item of the number of postings is set low for a search related to eating food and set high for a search related to cooking. Furthermore, it is considered that a user who is interested in eating food has acquired a lot of information on the latest restaurants. On the other hand, it is conceivable that a user who is interested in making a dish has acquired a lot of cooking method information. From this point of view, the distribution points of the information items of the RSS subscription may be set based on what kind of information is provided by the site registered as the RSS subscription.

  As an example, when searching for users who are interested in eating food, you can set 3 points for posting, 2 points for address registration, and 1 point for RSS subscription, as in the above example. . On the other hand, when searching for users who are interested in cooking, 5 points can be set for posting, 0 points for address registration, and 1 point for RSS subscription. In addition, when searching for users who are interested in eating food, the RSS subscription is given 2 points if the information about eating is subscribed to RSS, and RSS information is only related to cooking in general. If it was, it could be considered 1 point. In addition, when searching for users who are interested in cooking, the RSS subscription is given 2 points if the information about making is subscribed to RSS, and the information only related to cooking is subscribed to RSS. If it was, it could be considered 1 point. Thus, by changing the points according to the contents of the search, a more appropriate user can be displayed on the display unit.

  Although the above description is made from the viewpoint of eating and making a dish, the present embodiment can be applied to any matter without being limited to the dish. For example, distinguishing between a user who watches a movie or a theater and a user who plays, distinguishes a user who watches a literary work or a work of art from a user who creates it, and distinguishes a user who watches a sport from a user who performs it Etc. are considered. More generally, it is conceivable to distinguish between a user who performs an active action for something and a user who performs a passive action.

<< 5.2 Second Modification >>
As described above, the information stored as history information is not limited to the information described above, and any other appropriate information may be stored as history information indicating the user's action history. For example, actually making a call or sending information to a contact registered in the phone book, visiting (contacted) the location of the contact registered in the phone book, using the communication terminal 10 Information such as payment may be accumulated as history information. When a call is made, the user may actually make a reservation. The fact that a call has been made can be acquired from the call history of the communication terminal. In fact, the location information of the communication terminal can be obtained from information that the communication terminal periodically reports to the information providing server 40. A communication terminal with a built-in card that can be used for payment of money or points can be used for payment of money or points. Payment using the communication terminal can be obtained from the operation history of the communication terminal. Actions such as calling, calling and paying are more relevant for the subject matter compared to simply searching or just registering in the phone book.
