  FIG. 1 is a diagram showing features of the present invention. 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 that uses the communication server 30. Communicate. 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”. Further, the entire text data received from the start to the end of communication is regarded as a document set, and keywords that are characteristic of the document are extracted. 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 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 embodiments, TFIDF is mainly described. However, in addition to TFIDF, many important points are extracted in text mining (for example, document clustering), and those known techniques are used. Is not to be 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 use a keyword other than words obtained by morphologically dividing the received text data, such as vocabulary 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. Further, in response to the fact that the advertisement operation receiving unit 15 has received data indicating that a predetermined operation related to the advertisement by the other user has been received, the advertisement transmitting unit 14 sends data related to the advertisement to the terminal 60a of one user. Send.

  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 text data input by one user and the data related to the advertisement acquired by the advertisement distribution device 10 are transmitted to the terminal 60b of the other user. The communication I / F 1080 is an interface device for transmitting and receiving data without going through the computer network 70.

  FIG. 5 is a diagram showing the feature keyword DB 21 according to an embodiment of the present invention. The feature keyword DB 21 stores the total document number, the number of appearing documents, the TF value, the TFIDF (TF × IDF) value, the keyword, and information indicating the feature keyword in association with the user.

  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.

  FIG. 5 shows that as a result of calculating the TFIDF value, a keyword having a TFIDF value higher than a threshold value (for example, 5.0) is stored as a feature keyword with a * mark.

  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 the determination is YES, the process proceeds to step S111 in FIG. 7, and if the determination is NO, the process proceeds to step S103.

  In step S103, the CPU 1010 determines whether the data indicates that an advertisement has been selected by the user. 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, the process moves to a step S107, and if NO, the process moves to a step S104.

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

  In step S <b> 105, the CPU 1010 determines whether the data indicates that the user has performed an advertisement sharing instruction operation. More specifically, for example, in FIG. 8A described later, the CPU 1010 determines whether or not the share button 112a is pressed. If the determination is YES, the process proceeds to step S109, and if the determination is NO, the process proceeds to step S106.

  In step S <b> 106, the CPU 1010 determines whether or not the data indicates that the user has performed an instruction operation to transmit an advertisement URL. More specifically, for example, in FIG. 8A described later, the CPU 1010 determines whether or not the URL transmission button 113a is pressed. If the determination is YES, the process proceeds to step S110, and if the determination is NO, the process proceeds 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, the CPU 1010 transmits the advertisement selected by the operation on the user terminal 60a or the user terminal 60b to the other user terminal 60b or the user terminal 60a instructed by the operation, and the process is performed. Move to 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, the CPU 1010 transmits the URL of the advertisement selected by the operation on the user terminal 60a or the user terminal 60b to the other user terminal 60b or the user terminal 60a in communication, and the process is performed. Move to 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 the morpheme, except for vocabularies (eg, today, me, etc.) that are not likely to be related to advertisements. 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.
