  The recording device 330 is configured by an HDD, and has at least an SNS user management DB 331, a group management DB 332, a conversation attribute information DB 333, and a dictionary DB 334 in the recording area.

The SNS user management DB 331 is a database in which various types of information for managing each user who performs SNS use registration are stored as data. For example, in the SNS user management DB 331, as shown in FIG.
(1) a user ID corresponding to each user;
(2) a group ID corresponding to the group GR to which the user specified by the user ID belongs;
(3) the user information of the user;
(4) position information corresponding to the current position of the user;
Are registered (recorded) in association with each other.

  For example, in the case illustrated in FIG. 5, for the user specified by the user ID “userA”, the group ID “GR1” and the data of the user information “userA-profile” are recorded in association with each other. As the current position of “userA”, the position information “N: 35: 2: 11” (north latitude 35 degrees 2 minutes 11 seconds) / E140: 1: 20 (east longitude 140 degrees 1 minute 20 seconds) ”is registered. Yes.

  When one user belongs to a plurality of groups GR, the number of group IDs stored in the SNS user management DB 331 increases or decreases according to the number of group GRs that belong to the user.

  The group management DB 332 stores various data for managing the group GR created in the group creation process.

For example, in the group management DB 332, as shown in FIG.
(1) a group ID corresponding to the corresponding group GR;
(2) the group name of each group GR;
(3) Flag information indicating whether a group meeting is being held,
(4) a user ID belonging to each group GR (hereinafter referred to as “belonging user ID”);
(5) the group attribute information indicating the attribute of each group GR;
(6) position information indicating the current position of each group GR;
Are stored in association with each other. When the group meeting is not held, the user ID and position information at the time of the last meeting are registered.

In the conversation attribute information DB 333, conversation attribute information extracted from conversation information uploaded by the communication terminal device 10 is registered. For example, in the conversation attribute information DB 333, as shown in FIG. 7, (1) the group ID of the corresponding group GR,
(2) Total start time and total end time of conversations of each group GR;
(3) a word extracted from the conversation of each group GR and the number of appearances (that is, conversation attribute information);
Are stored in association with each other.

  In the dictionary DB 334, various dictionaries used when extracting conversation attribute information from conversation information are registered. For example, in this embodiment, the dictionary DB 334 includes “te”, “ni”, “wo”, “ha”, “me”, “me”, “you”, “today”, “yesterday”, and “tomorrow”. ”Or other words such as general nouns, conjunctions, particles / auxiliary verbs / utilization endings (hereinafter referred to as“ general words ”) that are less likely to indicate a topic from conversation attribute information. A general word dictionary for exclusion is recorded.

  The server management control unit 340 is mainly configured by a central processing unit (CPU), and integrally controls each unit of the server device 30 by executing a program.

  Specifically, the server management control unit 340 performs a login process to each user's SNS and the above-described group creation process based on a login request from the communication terminal apparatus 10 by a user operation in conjunction with the recording apparatus 330. Do.

  Further, the server management control unit 340 transmits the user ID to each communication terminal device 10 and performs the above conversation attribute information extraction process based on the conversation information uploaded from the communication terminal device 10 in conjunction with the recording device 330. To do. Then, the server management control unit 340 executes similarity information calculation processing based on the extracted conversation attribute information, and compares the calculated similarity information to match the interests, thoughts, and preferences. A group GR is specified.

  In particular, as the conversation attribute information extraction process, the server management control unit 340 extracts all the phrases and phrases included in the conversation information while performing the voice recognition process on the conversation information, and this is extracted. The morphological analysis is performed on the phrases and phrases, and the words included in the phrases and phrases are specified. At this time, the server management control unit 340 extracts only words that are not included in the general word dictionary, and based on the extracted words, the conversation attribute information (that is, the word that is the center of the topic, Information including the number of appearances of the word) is generated.

  For example, as shown in FIG. 8, the server management control unit 340 extracts voices and phrases such as “I went to the movie today” and “what movie I saw” and extracted the phrases as shown in FIG. While specifying each word such as “movie” and “◯ × △” from the sentence, the number of appearances is specified. Then, the server management control unit 340 provides a general word dictionary for the specified words and the number of appearances, and uses the words “movie” and “OxΔ” that are not included in the dictionary and the number of appearances as conversation attribute information. Generate.

  Note that the server management control unit 340 determines the aggregation start time and the aggregation end time by specifying the reception timing of the conversation information with the timer 350. For example, as shown in FIG. The total start time and total end time are registered together with the conversation attribute information.

  On the other hand, as shown in FIG. 9, the server management control unit 340 executes similarity information calculation processing based on conversation attribute information of each group for the past 30 minutes from the current time, for example, the current time.

  Specifically, the server control unit 340 first performs the calculations of (Expression 1) and (Expression 2) from the conversation attribute information of each group GR based on the conversation attribute information, and converts the conversation attribute information into vector data. Convert to

In (Expression 1) and (Expression 2), “key _j ” on the left side indicates a word, and the subscript “j” indicates an identification ID (for example, a number or alphabet) assigned to each word. is there. Further, “t _j ” and “S _j ” on the left side indicate the number of times each word appears.

  For example, in the case illustrated in FIG. 9, the number of appearances of three words “movie”, “radish”, and “reading” is “1”, “1”, “1” in the group GR1, and “3” in the group GR2. “0” and “2”, and the server management control unit 340 performs the operations of (Equation 1) and (Equation 2) based on the number of occurrences corresponding to all words, and calculates each component of the vector data. decide.

  Then, the server management control unit 340 calculates the cosine similarity “sim” according to the calculation formula shown by (Formula 3). The cosine similarity calculation is well known and will not be described in detail. The similarity calculation method is not limited to (Equation 3), and other methods such as Pearson's correlation may be used.

  On the other hand, in this similarity information calculation process, the server management control unit 340 has location information within a predetermined distance range (for example, within a range determined to be the same place or store, such as within a radius of 30 m to 100 m). Are identified based on the position information stored in the group management DB 332.

  That is, the server management control unit 340 identifies only other groups GR existing within a predetermined distance range, for example, the same event venue, among all the groups GR existing in the real space RS, The similarity information is calculated based on the conversation attribute information between the groups GR. As a result, in the real space RS, the server management control unit 340 can calculate similar information between the group GRs present in the same event venue, for example.

[4] Operation of Communication System Next, specific processing executed in the communication system of the present embodiment will be described with reference to FIGS.

  FIG. 10 is a flowchart showing processing executed in the communication system 1 from group creation to conversation information upload. FIG. 11 is a flowchart showing processing executed in the communication system 1 after conversation information upload. is there. FIG. 12 is a diagram illustrating an example of an image displayed on the communication terminal device according to the embodiment.

[4.1] Operation of Communication System from Group Creation to Conversation Information Upload First, the processing operation from group creation processing to conversation information upload will be described with reference to FIG. Prior to this processing, it is assumed that each user is in a state where SNS use registration has been completed, that is, various types of information have been registered in the SNS user management DB 331. The method for registering use in SNS is not different from that of a conventional SNS, and a description thereof is omitted. In this operation, the terminal management control unit 170 of the communication terminal device 10 controls the display control unit 150 to display the login instruction to the SNS by the user and input is performed on the operation unit 160. Is waiting.

  In this state, when the terminal management control unit 170 detects a login instruction to the SNS based on a user operation on the operation unit 160 (step Sa100), the terminal management control unit 170 reads a predetermined program from the application recording unit 101 and starts the browser. Meanwhile, a login request is made to the server device 30 (step Sa101).

  At this time, the terminal management control unit 170 cooperates with the current position acquisition unit 120 to cause the current position acquisition unit 120 to acquire position information, and to display the display control unit 150, the data processing unit 160, and the operation unit 160. In conjunction with this, the server device 30 is accessed and input of information necessary for various logins such as a login password for logging in to the SNS is accepted.

  Further, when transmitting the login request, the terminal management control unit 170 transmits a request with the user ID of the user of the own device and the acquired location information added, and waits for data reception from the server device 30. Transition to the state.

  Next, in the server device 30, when the communication control unit 310 receives this request for login (step Sa200), the server management control unit 340 searches the SNS user management DB 331 and associates it with the user ID of the login user. At the same time, the received location information is stored (updated) in the SNS user management DB 331 (step Sa201).

  Next, the server management control unit 340 searches the SNS user management DB 331, transmits a predetermined group ID and user ID to the communication terminal device 10 (step Sa202), and shifts to a reception standby state (step Sa203). Specifically, the server management control unit 340 reads the group ID of the group GR that has already been registered and has the user ID of the login user, and also exists in the vicinity of the current location indicated by the location information of the login user. The user ID of the logged-in user is read, and the read group ID and user ID are transmitted to the communication terminal device 10.

  Next, in the communication terminal device 10, the group ID (that is, the ID of the group GR registered by the user in the past) and each user ID (that is, in the vicinity of the current position of the user) transmitted from the server device 30 by the network communication unit 110. If the terminal management control unit 170 receives the user IDs of other existing users (step Sa102), the terminal management control unit 170 continues to use the past group GR in cooperation with the display control unit 150 and the operation unit 160. Alternatively, in order to create a new group GR, reception of input of necessary information such as a group name is started (step Sa103). For example, in conjunction with the operation unit 160, the display control unit 150 displays a display for prompting input of necessary information on the display unit 140, and the terminal management control unit 170 receives input from the operation unit 160.

  Next, when the terminal management control unit 170 detects the selection of the user registered in the group and the end of input of various information such as a group name via the operation unit 160 (step Sa104), the terminal management control unit 170 Group attribute information is generated based on the group ID, the user ID of the neighboring user, and the user input received from the device 30 (step Sa105).

  At this time, in the case of a group GR that has already been registered, the terminal management control unit 170 acquires the group attribute information of the group GR from the server device 30 and updates the group attribute information by updating the group GR. Generate.

  Next, the terminal management control unit 170 acquires the position information from the current position acquisition unit 120, and transmits the acquired position information and the generated group attribute information in association with each other to the server device 30 (step Sa106). ).

  Next, in the server device 30, when the communication control unit 310 receives the group attribute information and the position information (step Sa203), the server management control unit 340, based on the received group attribute information and the position information, the group management DB 332 Is updated (step Sa204).

  At this time, the server management control unit 340 allocates a group ID to the group GR and synchronizes the group ID with the communication terminal device 10. Then, the server device 30 sets the group ID assigned to the group GR as the communication terminal device 10 and shares the same group ID between both devices. Moreover, the server management control part 340 performs predetermined | prescribed processes, such as registering the newly joined communication terminal device 10 in the group management DB332, when using the group GR created in the past. This series of processing corresponds to group creation processing.

  Next, when the communication terminal device 10 detects a conversation information start instruction by a user's operation (step Sa111), the terminal management control unit 170 works in conjunction with the conversation information acquisition unit 130 to send the conversation information acquisition unit 130 the conversation information. Acquisition of the conversation information corresponding to is started (step Sa112). For example, the conversation information acquisition unit 130 acquires communication (that is, conversation) between users as conversation information in an indoor environment such as a private room of a store in the group GR. In addition, the conversation information acquisition unit 130 stores the acquired conversation information in the conversation information storage unit 102, and the terminal management control unit 170 starts counting by an internal timer.

  Next, when the terminal management control unit 170 detects the upload timing of the conversation information (for example, 30 seconds from the start of the timer count) based on the timer count (step Sa113), the terminal management control unit 170 works in conjunction with the network communication unit 110 to The conversation information stored in the storage unit 102 is uploaded to the server device 30 (step Sa114). At this time, the terminal management control unit 170 resets an internal timer.

  Next, the terminal management control unit 170 determines whether or not the user has instructed the end of acquisition of conversation information (step Sa115). At this time, if the terminal management control unit 170 determines that the end of acquisition of the conversation information is not instructed by the user, the terminal management control unit 170 returns to the process of step Sa113 and determines that the end of acquisition of the conversation information is instructed by the user. In step S116, the process related to the end of acquisition is executed and the fact is transmitted to the server device 30.

  Note that the terminal management control unit 170, in conjunction with the display control unit 150 and the operation unit 160, continuously requests group list data distribution (hereinafter referred to as “continuous distribution request”) as processing related to acquisition completion. A process of inquiring the user about whether or not to do is executed. Then, the terminal management control unit 170 transmits an end of acquisition of conversation information to the server device 30 including the continuous distribution request.

  Next, the terminal management control unit 170 determines whether or not the user has requested continuous distribution in the process of step Sa116 (step Sa117), and determines that the user has not requested continuous distribution. When the operation is terminated and it is determined that the user has requested continuous distribution, the process proceeds to step Sb101.

  Next, when the communication control unit 310 receives the conversation information in the server device 30 (step Sa211), the server management control unit 340 associates the conversation information with the group ID while specifying the reception time in conjunction with the timer 350. And temporarily stored in the ROM / RAM 320 (step Sa212). In the process of step Sa212, when the flag information indicating that the meeting is being held is OFF, the server management control unit 340 changes the flag information to ON.

  Next, the server management control unit 340 determines whether or not conversation information for a predetermined time (for example, conversation information for 5 minutes) has been stored in the ROM / RAM 320 (step Sa213). At this time, if the server management control unit 340 determines that the conversation information for a predetermined time is stored in the ROM / RAM 320, the server management control unit 340 proceeds to the process of step Sa214 and stores the conversation information for the predetermined time in the ROM / RAM 320. When it is determined that is not stored, the process proceeds to step Sa215.

  Next, when it is determined that the conversation information for a predetermined time is stored in the ROM / RAM 320, the server management control unit 340 starts the counting start time (that is, uploading from the communication terminal device 10 is started based on the reception time). Conversation information reception time) and aggregation end time (that is, the reception time of the last uploaded conversation information) while executing the conversation attribute information extraction process, the extracted conversation attribute information is converted into the conversation attribute information. Registered in the DB 333 (step Sa214), the process proceeds to step Sa215.

  At this time, when the conversation information not yet registered in the conversation attribute information DB 333 is stored in the ROM / RAM 320 when the server management control unit 340 receives the conversation information acquisition end instruction, the server management control unit 340 The conversation attribute information may be extracted from and registered in the conversation attribute information DB 333 or discarded.

  Next, the server management control unit 340 determines whether or not the communication control unit 310 has received a conversation information acquisition end instruction (step Sa215). At this time, if the server management control unit 340 determines that the communication control unit 310 has not received the conversation information acquisition end instruction, the server management control unit 340 returns to the process of step Sa211 and the communication control unit 310 ends the conversation information acquisition end. If it is determined that the instruction has been received, the process proceeds to step Sa216.

  Next, the server management control unit 340 determines whether or not a continuous distribution request is included in the acquisition end instruction (step Sa216), and if it is determined that the acquisition end instruction includes a continuous distribution request, When the process proceeds to step Sb201 and it is determined that the continuous distribution request is not included in the acquisition end instruction, this operation is ended.

  If the server management control unit 340 determines that the continuous distribution request is not included in the acquisition end instruction, the server management control unit 340 turns off the flag information indicating that the meeting of the corresponding group GR is being held and ends this operation.

[4.2] Operation after Uploading Conversation Information Next, the operation after uploading the conversation information will be described with reference to FIG. Note that the execution timing of this process is executed following the process of FIG. 10, but may be executed at intervals such as the next day of the meeting.

  Further, in the stage before the start of this process, in the communication system 1, the conversation information corresponding to each group GR is temporarily stored in the ROM / RAM 320 based on the process of FIG. For example, all necessary information illustrated in FIG. 6 is already stored.

  Further, prior to this processing, the user needs to log in to the SNS by the communication terminal device 10 and maintain the login state, but the login processing is omitted.

  First, in the communication terminal device 10, the terminal management control unit 170 controls the display control unit 150, and displays for prompting the user to input an instruction to acquire data related to recommended groups (hereinafter referred to as “group list data”). While waiting for input to be made to the operation unit 160 (step Sb101).

  Next, when an instruction to obtain group list data is given to the operation unit 160 by the user (step Sb102), the terminal management control unit 170 receives the server device via the network communication unit 110 based on the user operation. A group list data acquisition request is executed with respect to 30, and a transition is made to a reception standby state (Sb103). At this time, the terminal management control unit 170 adds the group ID of the user's group to the group list data acquisition request.

  Next, in the server device 30, when the communication control unit 310 receives the group list data acquisition request (step Sb201), the server management control unit 340 stores the group management DB 332 based on the group ID added to the acquisition request. Other items to be compared and compared with the conversation attribute information based on the position information and flag information corresponding to the group GR to which the user of the request source communication terminal apparatus 10 belongs (hereinafter referred to as “belonging group GR”). A group GR is specified (step Sb202).

  Specifically, the server management control unit 340 is a group GR in which flag information indicating that the meeting is being held is ON, and as described above, from the current position indicated by the position information corresponding to the group GR. A group GR existing within a predetermined distance range (for example, 30 m to 100 m) is specified as a comparison target of conversation attribute information.

  Next, the server management control unit 340 executes similarity information calculation processing based on the conversation attribute information of each identified group GR and the conversation attribute information of the belonging group BGR (step Sb203).

  At this time, the server management control unit 340 extracts, for example, the conversation attribute information for the previous 30 minutes (or the latest 30 minutes) from the current time based on the aggregation start time and the aggregation end time stored in the conversation attribute information DB 333. Then, the similarity of the extracted conversation attribute information is calculated.

  Next, the server control unit 340 specifies conversation attribute information that satisfies a predetermined condition, for example, the calculated similarity information exceeds a threshold (step Sb204), and calculates the similarity corresponding to the descending order of similarity. The ranks of the other groups GR used at the time of sorting are sorted (step Sb205), and the group attribute information in the upper group (for example, the upper third group) is read from the group management DB 332 (step Sb206).

  Next, the server management control unit 340 generates group list data based on the read group attribute information (step Sb207), and distributes the generated group list data to the communication terminal device 10 (step Sb208). )

  In the process of step Sb208, the server management control unit 340 displays each group attribute information on the communication terminal device 10 in a state that the user can view in the order sorted in step Sb205. Generate group list data.

  On the other hand, in the communication terminal device 10, when reception of the group list data by the network communication unit 110 is detected (step Sb111). The terminal management control unit 170 works with the display control unit 150 to display a list of group GRs as shown in FIG. 12 on the display unit 150 based on the received group list data (step Sb112). In this state, the user can select a group GR to apply for and apply for participation in the group GR. However, the application for participation in the group GR itself is the same as that of a conventional SNS. Are omitted.

  Next, the terminal management control unit 170 determines whether the user has instructed to dissolve the group or requested redistribution of the group list data (step Sb113), and transmits the determination result to the server device 30 (step Sb114). ) End this operation.

  Next, in the server device 30, when the server management control unit 340 receives the determination result in step Sb113 transmitted from the communication terminal device 10 (step Sb211), whether the group is instructed to disband or the group list data It is determined whether redistribution is requested (step Sb212).

  At this time, if the server management control unit 340 determines that the user has requested redistribution of the group list data, the server management control unit 340 returns to the process of step Sb208, and if it is determined that the user has requested the dissolution of the group, Is executed (hereinafter referred to as “group dissolution process”) (step Sb213), and this operation is terminated.

  The server management control unit 340 turns off the flag information in the group dissolution processing when the flag information indicating that the meeting of the group GR is being held is ON. However, when the user instructs group dissolution, when data deletion or other initialization is instructed, data corresponding to various information related to all groups GR recorded in the group management DB 332 and the conversation attribute information DB 333 May be cleared (deleted) and initialization in the server device 30 may be executed.

  As described above, in the communication system 1 of the present embodiment, the conversation attribute information indicating the conversation attribute in the group GR to which the user of the communication terminal device 10 belongs is extracted at predetermined time intervals, and the extracted conversation attribute information is extracted. Therefore, the conversation attribute information DB 333 is automatically updated, so that the conversation attribute information corresponding to the contents of the conversation made in the group GR is registered in the conversation attribute information DB 333 in real time.

  Then, conversation content similarity information is calculated based on conversation attribute information corresponding to real-time conversation content. Also, based on the similarity information, recommended group data is generated and distributed to the communication terminal device 10 of the user belonging to the group GR to be compared, and the user can browse based on the recommended group data. By displaying other groups GR of similar thoughts and interests, it is possible to recommend other groups GR.

  Therefore, in the present embodiment, it is possible to support exchange between the group GR constituted by a plurality of users and between the Internet communities while matching the real-time communication situation in the real space RS.

  In the case where the constant connection is employed as described above, the start time and the end time of the conversation attribute information generation process may be acquired by the timer 350 as the start time and the end time.
