FIG. 1 is a diagram illustrating features of the present embodiment . FIG. 1 is a functional block diagram showing operations of the advertisement distribution apparatus 10, user terminals 60a and 60b, and the advertisement server 40.

The advertisement distribution apparatus 10 as a server has a text receiving unit 11 as text receiving means for receiving text data input by one user and acquired by one user's terminal, and features of the text data based on the received text data. A feature keyword extraction unit 12 as an extraction unit for extracting the feature keyword to be shown, an advertisement acquisition unit 13 as an advertisement acquisition unit for acquiring data related to an advertisement based on the extracted feature keyword, and text data input by one user and acquired An advertisement transmission unit 14 is provided as advertisement transmission means for transmitting data related to advertisements to the other user's terminal. The user terminals 60a and 60b include display devices 61a and 61b, respectively, and send and receive text data and advertisements input by the user under the advertisement distribution device 10 using the communication server 30 (see FIG. 3 described later). And receive real-time communication. The advertisement server 40 transmits advertisement data having the highest relevance with the queried keyword according to a predetermined user interface.

  FIG. 2 is a diagram illustrating a relationship between a configuration unit that configures the function of the advertisement distribution apparatus 10 according to an embodiment of the present invention and data processed by the configuration unit.

  The text receiving unit 11 receives text data input by the user and acquired by the terminals 60a and 60b of one user.

  The feature keyword extraction unit 12 extracts a feature keyword indicating the feature of the text data based on the text data received by the text reception unit 11. In the feature keyword extraction, each text data received by the text receiving unit 11 is regarded as a document, and the feature keyword is extracted from the keyword obtained by morpheme division by the TFIDF method.

Here, the morpheme is the smallest linguistic unit having a meaning, and is a linguistic unit used when a sentence written in a natural language is divided. For example, “Today is good weather” is divided into “Today / Has / Good / Weather / Is it”. Furthermore, the capture of the entire text data received from the start to the end of communication and document set, extracts the keywords that provides the characteristic of the document. The keyword is not a simple appearance frequency in the entire text data, but a word that appears biased in a specific document is extracted. Specifically, for example, a TFIDF value is calculated, and a word indicating that the value is higher than a predetermined value is extracted as a feature keyword. The TFIDF method is a method of weighting keywords based on the appearance frequency of words. TFIDF is divided into the TF and IDF. TF is the Term Frequency (vocabulary frequency), and IDF is the Inverse Document Frequency (the reciprocal of the document frequency). That is, TFIDF represents the product of TF and IDF. In the following embodiment is described mainly with TFIDF, keyword extraction Ri Contact known many In text mining besides TFIDF (e.g., document clustering, etc.), the use of these known techniques It is not excluded.

  The feature keyword DB 21 (database) stores and stores the extracted feature keywords of one user and the feature keywords of the other user (see FIG. 5 described later). That is, the feature keyword extraction unit 12 obtains and stores keywords by dividing the received text data into morphemes, and extracts, from the stored keywords, for example, keywords whose TFIDF value calculated by the TFIDF method is higher than a threshold value. It memorize | stores in characteristic keyword DB21 as a keyword. Since the received text data increases from the start to the end of communication, the extracted feature keywords change each time the text data is received.

Note that the feature keyword extraction unit 12 can also be used as a keyword, except for words obtained by morpheme segmentation of received text data, such as words used for time and personality in normal conversation, such as yesterday and me. Good. By removing vocabulary that is unlikely to be relevant to advertisements from the keyword, it is possible to extract an accurate feature keyword.
Also, the feature keyword extraction unit 12 may use a keyword with a high appearance frequency as a feature keyword when a keyword having a TFIDF value higher than the threshold cannot be extracted (for example, when the received text data is small). . Even immediately after the start of communication, the feature keyword can be extracted based on the text data input by the user.

  The corresponding data in the feature keyword DB 21 is deleted when the communication ends (for example, the communication is interrupted for a certain time). This is because the nature of the content of the statement differs for each communication. It should be noted that a setting for whether or not to delete may be provided, and not deleted depending on the setting. When the content of communication is continued, more accurate feature keywords can be extracted.

  The advertisement acquisition unit 13 transmits the feature keyword to the advertisement server 40 based on the feature keyword extracted by the feature keyword extraction unit 12 according to a user interface determined in advance with the advertisement server 40, thereby Inquiries. A plurality of characteristic keywords can be transmitted. The advertisement server 40 transmits advertisement data having the highest relevance with the queried keyword as a query result. When there are a plurality of advertisements to be transmitted, a predetermined number (for example, 10) of advertisements are transmitted.

The advertisement transmission unit 14 transmits the text data input by the user 60a of the user and the data related to the advertisement acquired by the advertisement acquisition unit 13 to the terminal 60b of the other user. In addition, advertisement transmitter 14, advertisement operation reception unit 15, in response to receiving data indicating receipt of the predetermined operation related to advertising by the other user, the terminal 60a of one user, for advertising Send data.

  The advertisement operation receiving unit 15 receives data indicating that the terminal 60b of the other user has received a predetermined operation related to the advertisement by the other user. The predetermined operation related to the advertisement by the user includes an operation of selecting an advertisement, an operation of instructing the transfer of the advertisement, an operation of instructing transmission of the URL of the advertisement, or an operation of instructing sharing of the advertisement.

  The total number of documents is the total number of received text data. That is, the received text data is regarded as one document, and the total number of documents is counted every time the text data is received. The number of appearing documents is the number of documents in which the keyword appears. The TF value is the number of appearance frequencies of the keyword. IDF (reciprocal of document frequency) is a value obtained by dividing the total number of documents by the number of appearing documents, and the TFIDF (TF × IDF) value is typically calculated by the following equation (1). The higher the value, the higher the value. Here, in this embodiment, the word X is a keyword, one page is one document (received text data), the corpus is the entire received text data from the start to the end of communication, and the total number of pages is from the start of communication. Calculate as the total number of documents received by the end.

  6 and 7 are flowcharts showing processing contents of the advertisement distribution apparatus 10 according to an embodiment of the present invention. Note that this process starts, for example, by receiving a program start command and ends by receiving a program end command.

  In step S101, the CPU 1010 performs initialization processing for the main memory and the like. More specifically, the CPU 1010 initializes a work area and the like based on a value set in the hard disk 1070 (for example, a threshold value of the TFIDF value). Thereafter, the CPU 1010 advances the processing to step S102.

In step S102, the CPU 1010 determines whether text data has been received. If this determination is YES, CPU 1010 advances the processing to step S111 of FIG. 7, NO cases, CPU 1010 advances the process to step S103.

In step S103, the CPU 1010 determines whether data indicating that an advertisement has been selected by the user has been received . More specifically, for example, in FIG. 8 (1), which will be described later, the CPU 1010 displays, for example, an advertisement for “Hokkaido Ski Tour” from the advertisement display column 103a that displays an advertisement related to the other user's remarks. It is determined whether or not the advertisement display button 114a has been pressed as a case where it is selected by. If this determination is YES, CPU 1010 advances the processing to step S107, NO cases, CPU 1010 advances the process to step S104.

In step S <b> 104, the CPU 1010 determines whether data indicating that the user has performed an advertisement transfer instruction operation has been received . More specifically, for example, in FIG. 8A described later, the CPU 1010 determines whether or not the transmission button 111a is pressed. If this determination is YES, CPU 1010 advances the processing to step S108, NO cases, CPU 1010 advances the process to step S105.

In step S <b> 105, the CPU 1010 determines whether data indicating that an operation of an advertisement sharing instruction has been performed by the user has been received . More specifically, for example, in FIG. 8A described later, the CPU 1010 determines whether or not the share button 112a is pressed. If this determination is YES, CPU 1010 advances the processing to step S109, NO cases, CPU 1010 advances the process to step S106.

In step S <b> 106, the CPU 1010 determines whether data indicating that the user has performed an operation to send an advertisement URL is received . More specifically, for example, in FIG. 8A described later, the CPU 1010 determines whether or not the URL transmission button 113a is pressed. If this determination is YES, CPU 1010 advances the processing to step S110, NO cases, CPU 1010 advances the process to step S102.

  In step S107, the CPU 1010 transmits the advertisement selected by the user's operation on the terminals 60a and 60b to the operated user's terminals 60a and 60b, and the process proceeds to step S102. More specifically, for example, when the CPU 1010 receives data in which the advertisement display button 114a of “Hokkaido ski tour” is pressed from the advertisement display field 103a in FIG. The CPU 1010 transmits the advertisement of the selected “Hokkaido ski tour” to the user terminal 60a. An advertisement for “Hokkaido Ski Tour” is displayed in a pop-up on the user terminal 60a.

In step S108, CPU 1010 sends the ad also terminal 60 a user selected by the operation of the user terminal 60b, the terminal 60 b of the other user who instructed by the operation or the user of the terminal 60a, the processing To step S102. More specifically, in FIG. 9A described later, for example, when the “Hokkaido gourmet information” transmission button 121a is pressed, the CPU 1010 displays the selected “Hokkaido gourmet information” advertisement on the other side. It transmits to user's terminal 60b. An advertisement of “Hokkaido gourmet information” is displayed in the partner data display field 104b of the terminal 60b of the other user (see FIG. 9 (2)).

  In step S <b> 109, the CPU 1010 excludes the other user's terminal that is communicating the advertisement selected by the user's operation on the terminals 60 a and 60 b (for example, the terminal of the user who accepted the operation in the case of communication using three devices). 2) and the process proceeds to step S102. More specifically, in FIG. 8A described later, when the share button 112a is pressed, the CPU 1010 communicates the advertisement of the selected “Hokkaido ski tour” with the other user's terminal 60b and communicating. To other users' terminals. For example, an advertisement of “Hokkaido ski tour” is displayed in the partner data display field 104b of the terminal 60b of the other user.

In step S110, CPU 1010, the terminal 60 a or terminal URL of the advertisement selected by the operation of the user terminal 60b of the other users in the communication 60 b of the user or transmitted to the user terminal 60a, the processing To step S102. More specifically, in FIG. 8A described later, when the URL transmission button 113a is pressed, the CPU 1010 displays the advertisement URL of the selected “Hokkaido ski tour” as the terminal 60b of the other user. Send to.

  In step S111 of FIG. 7, the CPU 1010 analyzes the received text data input by one user. More specifically, the CPU 1010 analyzes text data input by one user based on the TFIDF method. That is, the received text data is divided into morphemes and keywords are extracted. Note that keywords may be extracted from morphemes obtained by dividing a morpheme, except for vocabularies that have a low possibility of being related to an advertisement (for example, today, I, etc.). By storing in advance a vocabulary that is unlikely to be related to an advertisement, keywords relating to the advertisement can be efficiently extracted. Thereafter, the CPU 1010 advances the processing to step S112.

  In step S112, the CPU 1010 calculates the TFIDF value of the keyword. That is, the TFIDF value is calculated based on the acquired keyword and the keyword stored in the feature keyword DB 21. More specifically, the CPU 1010 compares the keyword extracted from the received text data with the keyword stored in the feature keyword DB 21, and if they are the same, adds the stored frequency number and page number. Recalculate the TFIDF value. For a keyword different from the keyword stored in the feature keyword DB 21, the TFIDF value is calculated and newly stored in the feature keyword DB 21. Thereafter, the CPU 1010 shifts the processing to step S113.

  In step S113, the CPU 1010 extracts feature keywords. More specifically, the CPU 1010 extracts a keyword having a TFIDF value exceeding a threshold value from the keywords and stores it in the feature keyword DB 21 as a feature keyword.
