It is a sequence diagram in the present invention. It is a functional block diagram of the 2nd posting text transmission apparatus in this invention. It is a function block diagram of the 3rd posted message transmission apparatus in this invention.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a system configuration diagram according to the present invention.

  According to FIG. 1, a blog site server 3 is connected to the Internet. “Blog site server” is an SNS (Social Networking Service) server, for example, which is posted to a group of a plurality of other contributors who can view the posted text of the contributor. Publish your post. The SNS server is a miniblog server such as twitter (registered trademark), facebook (registered trademark), or mixi (registered trademark).

  A search server 4 is also connected to the Internet. The “search server” is a site such as Google (registered trademark) or Yahoo! (registered trademark), for example, and searches for an appropriate page for the keyword of the query received from the terminal. (Resource locater) is returned to the terminal. According to FIG. 1, the posted message transmission device 1 can access the search server 4.

  According to FIG. 1, a large number of terminals 2 access the blog site server 3 via an access network and the Internet. For example, it is assumed that a group composed of a plurality of other contributors B and C (accounts B and C) that can view the posted text of the contributor A (account A) is configured. In this case, the posted text posted by the poster A is viewed only on the terminal operated by the posters B and C. According to FIG. 1, for example, a posted message transmitting apparatus 1 accessed as an account A and a terminal 2 accessed as accounts B and C are connected to the blog site server 3.

  The account A assigned to the posted message transmitting apparatus 1 is for bot. Here, it is also preferable that accounts for a plurality of bots such as contents, news, and topics are provided in accordance with the preference of the user who follows the account.

  The posted message transmitting apparatus 1 according to the present invention distributes a recommended posted message (tweet) as a recommendation service in the interactive communication with the user in the SNS service by using the bot technology. Depending on the reaction (preference) of other users to the recommended posted text, the posted content of the recommended posted text is automatically updated.

FIG. 2 is a functional configuration diagram of the first posted message transmitting apparatus according to the present invention.
FIG. 3 is a sequence diagram in the present invention.

  The posted message transmission device 1 includes a communication interface 10 connected to the Internet, an API (Application Programming Interface) unit 11, a preference keyword table 12, a recommended document page search unit 13, a posted message generation unit 14, and a posting unit 15. A reaction information collecting unit 16, a feedback unit 17, and a document analysis engine 18. These functional components excluding the communication interface 10 are realized by executing a posted message transmission program that causes a computer installed in the terminal to function. In the following description, it is assumed that the miniblog server is a twitter server. Further, it is assumed that a large number of users are following the account A of the posted message transmission apparatus 1.

  The API unit 11 is a rule interface for the application of the posting unit 15 and the reaction information collection unit 16 to use the function of the application service of twitter. The API unit 11 is prepared differently for each miniblog server.

  The preference keyword table 12 is a table in which one or more preference keywords are registered. Moreover, it is also preferable that a time stamp of the registration date and time is registered in the preference keyword table 12 for each preference keyword.

  Arbitrary preference keywords (initial preference keywords) are registered in advance in the preference keyword table 12 as initial settings. According to FIG. 2, “baseball” and “boxing” are specifically registered. The initial preference keyword is set based on a user operation.

  The recommended document page search unit 13 searches for a recommended document page from the search engine server 4 for each preference keyword in the preference keyword table (see S13 in FIG. 3). The recommended document page search unit 13 transmits the preference keyword to the search engine server 4 and receives the title and URL of the searched recommended document page. The received title and URL are output to the posted text generation unit 14.

  The posted text generation unit 14 uses the template text to sequentially generate a posted text that includes the title and URL of the recommended document page as part of the template text (see S14 in FIG. 3). In the posted text, the posted text sent from the account A for bots appears to be spoken by an arbitrary character, so that the viewer may feel human friendliness with respect to the bot character. it can.

Examples of template sentences include the following, and several types are prepared.
"Today's critical news <A>
<B>
The title and URL of the recommended document page are embedded in <A> and <B>. According to FIG. 2, for example, the title and URL of the recommended document page related to “baseball” and the title and URL of the recommended document page related to “boxing” are included.

  The posting unit 15 sequentially posts the posted text to the blog site server 3 via the API unit 11 (for example, Twitter Tweet) (see S15 in FIG. 3). Here, it is also preferable that the time for transmitting the posted text is scheduled. For example, the date and time for sending a posted message is set. For example, the cycle may be “once every hour” “once every hour from 9:00 to 16:00” “once every hour from 16:00 to 23:00” or “12 A time setting such as “hour 5 minutes” may be used.

  The reaction information collection unit 16 collects reaction information of other contributors to the posted text from the blog site server 3 via the API unit 11 (see S16 in FIG. 3). Specifically, the number of reaction operations of other contributors to the posted text is counted from the blog site server 3 via the API unit 11. The number of reaction operations is, for example, the number of clicks on a link, the number of spread transmissions (for example, ReTweet in twitter), and / or the number of favorite registrations. The number of reaction operations is counted for each posted sentence. Further, the reaction operation as the reaction information is based on the reaction operation in the user who follows the account A of the posted message transmission device 1.

  According to FIG. 2, the reaction information collection unit 16 specifically detects the document pages of “Entertainment News 1” and “Sports News 2” as the number of times of response operations of other posters is large. Then, the reaction information is output to the feedback unit 17.

  The document analysis engine 18 extracts a keyword representing the content of the document page from the text included in the document page. The document analysis engine 18 detects a keyword from a document page by morphological analysis or N-gram index character string extraction method. Of these keywords, the higher-ranking keywords having a high appearance frequency are output to the feedback unit 17.

  Morphological analysis refers to a technique in which a natural language sentence in a posted sentence is divided into columns of morphemes (the smallest unit having meaning in the language) using a word dictionary and a dependency dictionary, and each part of speech is discriminated. By this analysis, for example, only noun morphemes can be extracted as keywords, and keywords with a high appearance frequency can be detected.

  In addition, N-gram is not based on dictionary or syntactic analysis for key extraction of transposed index (combination of keywords and pages), but simply counts words cut out for every fixed number of characters (for example, every two characters). The technology to do. N means that there can be a plurality of character units to be cut out. For example, the key of the table of contents is created by always cutting out a two-letter word without considering the meaning of the word.

Tf-idf (Term
Frequency-Inverse Document Frequency) technology may be used. This technique is a kind of weight related to a word in a document, and is based on two indexes, tf (word appearance frequency) and idf (inverse document frequency).

  Of course, it is also preferable to use some filtering function so that only meaningful keys are extracted keys without using morphological analysis or N-gram index character string extraction methods as they are.

  The feedback unit 17 derives a document page having a high response from other contributors from the reaction information, extracts a keyword from the document page using the document analysis engine 18, and newly registers the keyword as a preference keyword in the preference keyword table. (See S17 in FIG. 3). For example, the feedback unit 17 may extract a keyword from a document page having a predetermined number of reaction operations or more, and newly register it in the preference keyword table. For example, a preference keyword may be extracted from the top several document pages based on reaction information tabulated on a daily basis.

  Further, the feedback unit 17 deletes a preference keyword having a past time stamp after a certain period (for example, one week) from the preference keyword table. Furthermore, it is also preferable that the feedback unit 17 deletes a lower number of unpreferred preference keywords from the preference keyword table. By such an operation, the preference keyword table is constantly updated (tuned) in interactive communication.

  FIG. 4 is a functional configuration diagram of the second posted message transmitting apparatus according to the present invention.

  The second posted message transmitting device in FIG. 4 differs from the first posted message transmitting device in FIG. 2 only in the functions of the posted message generating unit 14 and the reaction information collecting unit 16. The posted message generation unit 14 includes a link of an address to a redirect page whose redirect source is the posted message transmission device in the posted message. When another user who has viewed the posted text clicks on this link, the user is redirected to the content detailed information or the like via the posted text transmitting apparatus 1. By clicking on a link in the posted text (tweet), the posted text transmitting device is accessed, and a detailed content information page corresponding to the posted text in the redirect is displayed on the terminal. The reaction information collection unit 16 can count the number of times the posted message transmission device 1 has redirected for each posted message. Thereby, the reaction information collection unit 16 can collect reaction information of other contributors to the posted text from the blog site server 3. Then, the feedback unit 17 newly registers the keyword included in the posted sentence with the redirection count equal to or greater than the predetermined number in the preference keyword table 12.

  FIG. 5 is a functional configuration diagram of the third posted message transmitting apparatus according to the present invention.

  The third posted message transmission device in FIG. 5 differs from the first posted message transmission device in FIG. 2 only in the functions of the reaction information collection unit 16 and the feedback unit 17. The reaction information collection unit 16 collects posted messages (tweets) of other users who follow the account A of the posted message transmission apparatus. Such a function is generally referred to as a “crawler”. “Crawler” refers to a function that automatically and periodically obtains a page that can be viewed by the user, and is provided as, for example, a Twitter API.

  The feedback unit 17 inputs the collected plurality of posted sentences to the document analysis engine 18. The document analysis engine 18 analyzes the input posted sentence, extracts high-order keywords having a high appearance frequency, and outputs the keywords to the feedback unit 17. The feedback unit 17 newly registers the keyword output from the document analysis engine 18 in the preference keyword table 12.

  In the initial stage, the document analysis engine 18 may extract an initial preference keyword from a document page selected based on a user operation. The extracted initial preference keyword is registered in the preference keyword table. Thus, the user may specify the document page (or URL) that he / she likes without specifying the initial preference keyword.

  As described above in detail, according to the posted message transmission program, apparatus, and method of the present invention, the recommended posted message as the recommendation service is used for the recommended service in the interactive communication with the user in the SNS service. Can be delivered. In particular, according to the present invention, it is possible to distribute a recommended posting according to, for example, a follower preference in twitter. In addition, the posted text does not feel an inorganic image as a general advertisement, and an organic image that imitates a real person in the natural exchange of posted text with the user. You can feel it.

  Various changes, modifications, and omissions of the above-described various embodiments of the present invention can be easily made by those skilled in the art.
