The processing unit 13 includes a posted information storage unit 131, a browsing history storage unit 132, a dynamic profile information generation unit 133, and a link generation unit 134. The transmission unit 14 includes a posting information transmission unit 141 and an auxiliary information transmission unit 142.

The storage unit 11 can store various types of information. The various types of information include, for example, static profile information, dynamic profile information, posted information, user identifiers, terminal identifiers, auxiliary information identifiers, term databases, and the like. Static profile information, dynamic profile information, and posting information will be described later.

The user identifier is an identifier that identifies each of two or more users who are interacting with each other. The user identifier is, for example, an e-mail address, a telephone number, an ID, or the like, but any information that can identify the user may be used. The terminal identifier is an identifier that identifies the user terminal 2 of each of two or more users who are interacting with each other. The terminal identifier is, for example, a MAC address, an IP address, or the like, but any information that can identify the user terminal 2 may be used. It is also possible to use the terminal identifier of the user terminal 2 owned by the user as the user identifier of the user.

Auxiliary information is information for assisting dialogue. The data type and content of the auxiliary information do not matter. Auxiliary information is, for example, a web page, user information of another user similar to one user, another series of post information similar to a series of post information including one post information, or a series including one post information. Any one or more of the auxiliary information at the link destination of another series of posted information similar to the posted information of.

The auxiliary information may be, for example, knowledge support information or interest arousal support information. Knowledge support information is information that assists the user in acquiring knowledge. For this reason, knowledge support information is usually linked to less important terms (eg, frequency of occurrence). The term of low importance is, for example, a term having a importance of less than or lower than the threshold value or a term having a lower importance of N (N is a natural number of 1 or more). The interest-raising support information is information that arouses the user's interest. The interest-raising support information is, for example, information that the user who receives the posted information wants to inform the user who sends the posted information. Interest-raising support information is usually linked to a term of high importance because it is intended to promote conversation by arousing interest. The term of high importance is, for example, a term having a importance equal to or higher than the threshold value or a term having a higher importance than the threshold value, and a term having a higher importance N (N is a natural number of 1 or more).

The web page is, for example, information acquired by a web search, for example, a lecture video which is a video of a lecture, a supplementary material of a lecture, and the like, but the contents thereof are not limited. The user information of another user similar to one user is, for example, a web page in which the user information of the user (similar user) is described, information in a database in which the information of the similar user is stored, or the like, but an email address. And so on. Similar users will be described later.

One posted information is information composed of a series of remarks by two or more users, and is, for example, content such as chat or SNS. The chat is, for example, Line, ChatPad, or the like. The SNS is, for example, facebook (registered trademark), Instagram (registered trademark), TWITTER (registered trademark), and the like.

The other series of post information similar to the series of post information including one post information is, for example, content (similar content) similar to the series of post information (content). Similar contents will be described later. The auxiliary information linked to by another series of posted information similar to the series of posted information including one posted information is the auxiliary information linked to the similar content. When the posted information is a character string, whether or not the series of posted information and the other series of posted information are similar is determined by, for example, whether or not the set of character strings is similar. Such a technique is a known technique.

In addition, the auxiliary information usually corresponds to the auxiliary information identifier. The auxiliary information identifier is an identifier that identifies auxiliary information. The auxiliary information identifier is, for example, the URL of a web page having the above-mentioned video, material, user information, content, etc., the user's e-mail address, or the like, but the type is not limited.

The term database is a database in which two or more terms are registered. Usually, two or more preselected terms are registered in the term database. Each term in the term database may be associated with importance based on, for example, the frequency with which the term is searched. A term is usually a word but may include a phrase or sentence.

Two or more pairs of the user identifier and the static profile information are stored in the user static profile storage unit 111. The static profile information is information indicating the static profile of the user. It can be said that the static profile information is, for example, information indicating the characteristics of a user who does not change frequently more than a certain frequency. The static rop file information includes, for example, the user's name, address, contact information, grade, class, attendance status, proficiency level, etc., but the type does not matter.

The user dynamic profile storage unit 112 stores two or more pairs of the user identifier and the static profile information. The dynamic profile information will be described later.

Two or more pairs of the user identifier and the posted information are stored in the posted information storage unit 113. The posted information is information posted by a user identified by a paired user identifier. Posting refers to what the user says. The posted information is usually a character string, but may be image or audio data. The data type of posted information does not matter. The posting in the present embodiment is usually one remark by one user. On the other hand, a series of remarks by two or more users is called "dialogue". In the following, a series of posted information corresponding to a series of remarks may be referred to as "dialogue information".

In the posting information storage unit 113, the pair of the user identifier and the posting information is usually stored in a time series, but instead of or in addition to this, it may be stored in association with the time information. The time information is information indicating the time when the posted information was posted. The time may include the date (year, month, day) in addition to the hour, minute, and second (the same shall apply hereinafter). Note that storing in association with each other includes the case where the pair of the user identifier and the posted information has the time information.

The receiving unit 12 receives various types of information. The various types of information include, for example, posted information from the user terminal 2, instructions for outputting auxiliary information corresponding to the link added to the posted information (hereinafter, may be referred to as "instruction to the link"), and one. Other users' actions on the user's posted information. The instruction to the link usually has a post information identifier and a character string. The instruction to the link is, for example, information for specifying the position of the character string corresponding to the post information identifier and the link (for example, the start offset and the end offset of the character string). The posted information identifier is an identifier that identifies the posted information. The character string is a character string that constitutes post information, and is a character string (for example, a term) to which a link is added. However, the data structure of the instruction to the link does not matter. The action usually has a post information identifier and an action identifier. An action identifier is an identifier that identifies an action. However, the data structure of the action does not matter. The receiving unit 12 receives the action in pairs with the user identifier. The specific actions will be described later.

The posting information receiving unit 121 receives the posting information from two or more user terminals 2. The posting information receiving unit 121 usually receives the posting information in pairs with the user identifier. It should be noted that receiving in pairs includes the case where the posted information has a user identifier.

The instruction receiving unit 122 receives an instruction to the link from the user terminal 2. The instruction receiving unit 122 usually receives an instruction to the link in pairs with the user identifier.

The processing unit 13 performs various processes. The various processes include the processes of the posted information storage unit 131, the browsing history storage unit 132, the dynamic profile information generation unit 133, and the link generation unit 134, which will be described later, and various determinations and other processes described in the flowchart.

The posting information storage unit 131 stores the posting information received by the posting information receiving unit 121 in the posting information storage unit 113. The posted information storage unit 131 normally stores the posted information in chronological order in association with the user identifier.

The browsing history storage unit 132 stores the browsing history. The browsing history is a history related to browsing of auxiliary information output in response to an instruction to a link. The browsing history has, for example, a user identifier, an auxiliary information identifier, and time information. The time information is information indicating the time when the auxiliary information was viewed. However, the data structure of the browsing history does not matter.

The dynamic profile information generation unit 133 uses the generation target to generate the dynamic profile information of the user identified by one user identifier. The generation target is information used to generate dynamic profile information.

The generation target is, for example, post information stored in the post information storage unit 113, and one or more post information paired with one user identifier. The generation target is one or more post information paired with one user identifier, dialogue information including one or more post information of another user corresponding to the post information of the one user, and one user instructed a link. Auxiliary information output at the time, one or more types of information in the term database.

The dynamic profile information is information indicating the dynamic profile of one user. The dynamic profile information is, for example, a set of importance of two or more terms (for example, feature words) used in one or more posted information corresponding to one user identifier, but is not limited to this. In the following, a set of the importance of two or more terms may be referred to as a “term vector” or a “feature vector”. Further, the generation may be a process of updating a part or all of the existing dynamic profile information. The timing at which the dynamic profile information generation unit 133 generates the dynamic profile information does not matter.

The dynamic profile information generation unit 133 is the post information stored in the post information storage unit 113, and is identified by the one user identifier using one or more post information paired with the one user identifier. Generate user dynamic profile information.

The dynamic profile information generation unit 133 may generate the dynamic profile information of the one user by using two or more terms constituting the one or more posted information posted by at least one user.

The dynamic profile information generation unit 133 uses, for example, interactive information including one or more posted information of one user and one or more posted information of another user corresponding to the posted information of the one user. , The dynamic profile information of the one user may be generated. The one or more posted information of another user corresponding to the posted information of one user may be the posted information in a series of posted information, or the posted information of another user immediately before the posted information of the one user. It may be the posted information, the posted information of another user immediately after the posted information of the one user, or the posted information of another user immediately before and after.

Alternatively, the dynamic profile information generation unit 133 generates dynamic profile information by using not only one or more posted information of one user but also auxiliary information output when the one user instructs a link. You can do it. The dynamic profile information generation unit 133 may generate dynamic profile information by using one or more posted information, dialogue information, and auxiliary information.

The generation of dynamic profile information is usually a process of extracting one or more terms from a generation target and obtaining a set of pairs of terms and importance.

The dynamic profile information generation unit 133 refers to, for example, a term database, extracts one or more terms from one or more posted information, and generates dynamic profile information including a set of pairs of terms and importance. You may. The terms that make up the dynamic profile information are preferably feature words. The characteristic word is a term that appears characteristically in the remark of the user. The characteristic word is, for example, a term having a frequency higher than the threshold value or a term having a frequency lower than the threshold value. The characteristic words are, for example, terms up to the top N (N is a natural number of 1 or more) with a high frequency of appearance, or terms up to the top M (M is a natural number of 1 or more) with a low frequency of appearance. Not exclusively.

For example, the dynamic profile information generation unit 133 extracts one or more terms from the generation target, obtains the appearance frequency of each of the one or more terms, and uses the obtained occurrence frequency to among the one or more terms. One or more feature words may be extracted from the to generate dynamic profile information including a set of pairs of feature words and frequency of occurrence (hereinafter, may be referred to as “feature vector”). The frequency of appearance refers to the number of occurrences of the term relative to the total number of appearances of all the terms. The appearance frequency is, for example, information quantified by a TF value, an IDF value, a TF-IDF value, or the like. The TF (Term frequency) value is, for example, a value indicating the frequency of appearance of the term in all posted information. The IDF (Inverse Document Frequency) value is a value related to how many posted information the term is commonly used in, and usually, the larger the number of posted information in which the term appears, the smaller the value. .. The TF-IDF value is, for example, the product of the TF value and the IDF value. However, these are merely examples, and the type of appearance frequency and the calculation method do not matter.

In addition, the dynamic profile information generation unit 133 may generate dynamic profile information by using action information related to actions of another user corresponding to the posted information of one user. The action of another user corresponding to the posted information of one user (hereinafter, may be simply referred to as “action”) is, for example, an action performed by another user in response to a statement of one user. The action is, for example, a user's operation or action on the posted information, and is, for example, pressing a button such as "Like" or "Share" displayed in pairs with the posted information, but is not limited to this. The action information usually includes information indicating the number of actions. The information indicating the number of actions is, for example, information indicating the number of times the "Like" is pressed, the number of times the "Share" is pressed, and the like, but any information regarding the number of actions can be used.

The link generation unit 134 generates a link to auxiliary information that assists the dialogue between two or more user terminals 2 when a predetermined condition is satisfied. The predetermined condition may be, for example, a condition for a character string, a condition for a user, or a condition for a series of posted information. The case of having a predetermined condition may be, for example, that dynamic profile information can be configured, another user (similar user) similar to the user may be found, or a series of similar posts. Information (similar content) may exist, and any condition that can trigger link generation may be used.

One of the preferable conditions for the character string is that the importance of the term composed of the character string is "greater than or equal to the first threshold value or greater than the first threshold value". Another preferable condition for the character string is that the importance of the term composed of the character string is "less than or equal to the second threshold value or less than the second threshold value".

A similar user is a user who is so similar to the user that the dynamic profile information satisfies a predetermined condition. Similar content is a series of posted information that is so similar to the content that the vector of terms appearing there satisfies a predetermined condition.

In general, a link is information that represents the location of another information described in one piece of information, and generating a link means adding a link to another piece of information to another piece of information. Including. Then, the generation of the link in the present embodiment is to add the link to the auxiliary information to the information output by the user terminal 2. The information output by the user terminal 2 is usually posted information, but may be, for example, an e-running screen, an e-mail screen, or the like, regardless of the type. The link is usually added to the character string that constitutes the posted information, but it may be added to the image included in the screen, or it may be added in units of screens. Further, the link location (character string, etc.) to which the link is added may be different for each user. Furthermore, even if a link is added to the same place, the link destination (auxiliary information linked to a character string or the like) may differ depending on the user.

That is, the link generation unit 134 is, for example, a character string that satisfies a predetermined condition in the post information received by the reception unit 12 according to the user terminal 2 or the user who outputs the post information, and is a different character. A link to auxiliary information may be generated for the column. Further, the link generation unit 134 may generate links to different auxiliary information depending on, for example, the user terminal 2 that outputs the posted information or the user.

The link generation unit 134 determines, for example, a character string of a target for which a link is generated by using dynamic profile information. Specifically, the link generation unit 134 may generate a link to auxiliary information for a term whose importance is equal to or higher than the threshold value or whose importance is greater than the threshold value in the posted information. Alternatively, the link generation unit 134 may generate a link to the auxiliary information for the terms whose importance is less than or equal to the threshold value or whose importance is less than the threshold value in the posted information.

The link generation unit 134 is, for example, post information of another user, and it is preferable to generate a link to auxiliary information for a character string in the post information output to the user terminal 2 of one user. is there. Further, it is preferable that the link generation unit 134 does not generate a link for the character string in the posted information posted by itself, for example. That is, what is in the above posted information is preferably in the posted information of another person.

In addition, the link generation unit 134 has a degree of importance equal to or higher than the first threshold value or a degree of importance of the posted information, regardless of whether it is the posted information posted by itself or the posted information posted by another user. A link to the first auxiliary information may be generated for a term larger than one threshold. In addition, the link generation unit 134 has a second threshold value or less or a highest importance among the posted information, regardless of whether the posted information is posted by itself or posted by another user. A link to the second auxiliary information may be generated for a term smaller than the two thresholds.

The link generation unit 134 may also generate a link by using the static profile information. It is desirable that the link generation unit 134 generate a link to the link destination according to the static profile information. The link destination according to the static profile information is, for example, a lecture video according to the grade, class, etc., supplementary materials according to the attendance status, proficiency level, etc., but is not limited to this.

The link generation unit 134 acquires a series of post information during the dialogue, searches for another series of post information similar to the series of post information from the post information storage unit 113, and performs the similarity. You may generate a link that uses other series of posted information as auxiliary information. In such a case, the link source may be a series of posted information currently in the middle of a dialogue, or may be a screen. When the link source is a screen, the link generation unit 134 may generate a link such as a button for calling another similar series of posted information.

Further, the link generation unit 134 detects the dynamic profile information whose similarity with the dynamic profile information of one user is equal to or greater than the threshold value or greater than the threshold value, and assists the information of other users corresponding to the dynamic profile information. You may generate a link as information. The information of other users is, for example, the user identifier of the user, the static profile information of the user, and the like. In such a case, the link source may be a screen. When the link source is a screen, the link generation unit 134 may generate a link such as a button for calling information of another user.

The transmission unit 14 transmits various types of information. The various types of information include, for example, the above-mentioned posted information.

The posting information transmitting unit 141 transmits the posting information having the link generated by the link generating unit 134, which is the posting information received by the posting information receiving unit 121. However, a part of the posted information transmitted by the posted information transmitting unit 141 may be the posted information having no link. The posting information transmission unit 141 normally transmits the posting information to one or more user terminals 2 excluding the user terminal 2 which is the transmission source of the posting information. Each of the 1 or more user terminals 2 is a user terminal 2 of a user who interacts with the user terminal 2 which is the transmission source of the posted information. In addition, the posting information transmission unit 141 may also transmit the posting information to the user terminal 2 which is the transmission source of the posting information.

The auxiliary information transmitting unit 142 transmits auxiliary information (hereinafter, may be referred to as “link destination auxiliary information”) corresponding to the instruction to the link received by the instruction receiving unit 122. The auxiliary information transmission unit 142 usually transmits the auxiliary information of the link destination to the user terminal 2 which is the transmission source of the instruction.

However, the processing unit 13 and the like may be realized by hardware (dedicated circuit).

The transmission unit 14, the posting information transmission unit 141, the auxiliary information transmission unit 142, and the terminal transmission unit 24 may or may not include one or more hardware of the communication module or the broadcasting module. The transmission unit 14, etc. can be realized by a device driver such as a communication module, or by a communication module or the like and its device driver or the like.

The terminal output unit 26 may or may not include an output device such as a display or a speaker. The terminal output unit 26 and the like can be realized by the driver software of the output device, or by the output device and its driver software and the like.

Next, the operation of the dialogue system 100 will be described with reference to the flowcharts of FIGS. 4 to 7. The description of the items described is omitted or simplified.

FIG. 4 is a flowchart illustrating the operation of the posting information processing device 1.

(Step S102) The posting information storage unit 131 stores the posting information received by the posting information receiving unit 121 in the posting information storage unit 113 in association with the user identifier.

(Step S103) The dynamic profile information generation unit 133 executes a dynamic profile information generation process, which is a process of generating dynamic profile information corresponding to the user identifier. The dynamic profile information generation process will be described with reference to the flowchart of FIG.

(Step S104) The link generation unit 134 executes a link generation process, which is a process of generating a link to auxiliary information. The link generation process will be described with reference to the flowchart of FIG.

(Step S105) The posting information transmitting unit 141 is the posting information received by the posting information receiving unit 121, and the posting information having a link or the posting information having no link generated by the link generating unit 134 is the posted information. Transmission is performed to one or more user terminals 2 (other user terminals 2) excluding the user terminal 2 which is the transmission source. For example, the storage unit 11 stores a group of user identifiers corresponding to two or more users participating in one dialogue, and the post information transmission unit 141 stores the post information among the user identifiers of the group. The posted information may be transmitted to a user identifier other than the user identifier received in pairs with. After that, the process returns to step S101.

(Step S106) The processing unit 13 determines whether or not the instruction receiving unit 122 has received the instruction to the link in pairs with the user identifier. If the instruction receiving unit 122 receives the instruction to the link in pairs with the user identifier, the process proceeds to step S107, and if not, the process proceeds to step S109.

(Step S107) The processing unit 13 acquires auxiliary information (auxiliary information of the link destination) corresponding to the instruction to the link received by the instruction receiving unit 122. Then, the auxiliary information transmission unit 142 transmits the acquired auxiliary information to the user terminal 2 which is the transmission source of the instruction.

(Step S108) The processing unit 13 stores the browsing history having the auxiliary information identifier that identifies the auxiliary information in the storage unit 11 in association with the terminal identifier. Return to step S101. The browsing history may include the browsing time. The browsing time is the time when the auxiliary information is browsed. For example, the processing unit 13 may consider the time from the transmission of the auxiliary information to the transmission of another auxiliary information or other information as the browsing time. The posting information processing device 1 may receive the browsing time from the user terminal, and the processing unit 13 may acquire the browsing time. However, the method of obtaining the viewing time does not matter.

(Step S109) The processing unit 13 determines whether or not the receiving unit 12 has received an action of another user with respect to the posted information of the user. If the receiving unit 12 receives the action, the process proceeds to step S110, and if the action is not received, the process returns to step S101.

(Step S110) The processing unit 13 stores action information including the number of times of the action (for example, the number of times of pressing "like" or the like) in association with the user identifier corresponding to the posted information. After that, the process returns to step S101.

In the flowchart of FIG. 4, the execution timing of the dynamic profile information generation process and the link generation process does not matter.

Further, in the flowchart of FIG. 4, for example, the process starts when the power of the posting information processing apparatus 1 is turned on, and ends when the power is turned off or an interrupt for the end of the process occurs. However, the trigger for the start and end of processing does not matter.

FIG. 5 is a flowchart illustrating a dynamic profile generation process.

(Step S201) The dynamic profile information generation unit 133 extracts terms from the generation target of posted information and the like. Note that the term extraction is, for example, a process of analyzing a character string to be generated by morphological analysis and extracting a term of an independent word or a term of a specific part of speech (for example, a noun or a noun phrase) from the morphological element. Further, in the extraction of terms, for example, the term database is referred to, and the terms included in the term database are acquired from the generation target by a search process.

(Step S202) The dynamic profile information generation unit 133 determines whether or not one or more terms have been extracted from the posted information. If one or more terms are extracted, the process proceeds to step S202, and if no one term is extracted, the process returns to higher processing.

(Step S203) The dynamic profile information generation unit 133 sets the initial value “1” in the variable i. The variable i is a variable that sequentially indicates the unprocessed terms among the one or more extracted terms.

(Step S204) The dynamic profile information generation unit 133 determines whether or not there is the i-th term. If there is an i-th term, the process proceeds to step S205, and if not, the process proceeds to step S207.

(Step S205) The dynamic profile information generation unit 133 acquires the importance of the i-th term by using one or more posted information corresponding to the user identifier and one or more of the history information or the action information. ..

(Step S206) The dynamic profile information generation unit 133 increments the variable i. After that, the process returns to step S204.

(Step S207) The dynamic profile information generation unit 133 associates the dynamic profile information composed of the acquired set of importance of one or more terms with the user identifier, and stores the user dynamic profile information unit 112. accumulate. After that, it returns to the upper processing.

FIG. 6 is a flowchart illustrating the link generation process.

(Step S301) The link generation unit 134 acquires a user identifier that identifies a user who receives the posted information from the storage unit 11.

(Step S302) The link generation unit 134 acquires the dynamic profile information corresponding to the user identifier from the user dynamic profile storage unit 112.

(Step S303) The link generation unit 134 sets the initial value “1” in the variable i.

(Step S304) The link generation unit 134 determines whether or not there is an i-th term. If there is an i-th term, the process proceeds to step S305, and if not, the process returns to higher processing.

(Step S305) The link generation unit 134 determines whether or not the importance of the i-th term satisfies the condition. If the importance of the i-th term satisfies the condition, the process proceeds to step S306, and if the importance is not satisfied, the process proceeds to step S308.

(Step S306) The link generation unit 134 acquires an auxiliary information identifier that identifies the auxiliary information corresponding to the i-th term from the storage unit 11.

(Step S307) The link generation unit 134 generates a link from the i-th term to the auxiliary information. After that, the process proceeds to step S317.

(Step S308) The link generation unit 134 determines whether or not the i-th term is a user name. If the i-th term is a user name, the process proceeds to step S309, and if not, the process proceeds to step S313.

(Step S309) The link generation unit 134 calculates the degree of similarity between users.

(Step S310) The link generation unit 134 uses the calculated similarity to determine whether or not there is another user (similar user) similar to the user. If there is a similar user, the process proceeds to step S311. If not, the process proceeds to step S313.

(Step S311) The link generation unit 134 acquires an auxiliary information identifier that identifies auxiliary information corresponding to a similar user from the storage unit 11.

(Step S312) The link generation unit 134 generates a link to the auxiliary information.

(Step S313) The link generation unit 134 calculates the degree of similarity between a series of posted information (contents).

If there is similar content, the process proceeds to step S315, and if not, the process proceeds to step S317.

(Step S315) The link generation unit 134 acquires an auxiliary information identifier that identifies auxiliary information corresponding to similar contents from the storage unit 11.

(Step S316) The link generation unit 134 generates a link to the auxiliary information.

(Step S317) The link generation unit 134 increments the variable i. After that, the process returns to step S304.

When the number of users who receive the posted information is 2 or more, a different link is generated depending on the user by performing the process according to the flowchart of FIG. 6 for each of the 2 or more users. The link that differs depending on the user includes one or more cases where the term (character string) to which the link is set differs, or the auxiliary information of the link destination differs depending on the user.

Further, in the flowchart of FIG. 6, the link generation unit 134 uses the dynamic profile information to generate the link, but it is also possible to generate the link without using this. For example, when a term registered in the term database appears in the posted information, the link generation unit 134 may generate a link using only the existing importance registered in pairs with the term. Alternatively, you can generate a link for any term without reference to any importance. Further, the link generation unit 134 may not refer to the term database, for example, may search the web for a noun appearing in the posted information and generate a link to a web page included in the search result.

FIG. 7 is a flowchart illustrating the operation of the user terminal 2.

(Step S401) The terminal processing unit 23 determines whether or not the terminal reception unit 22 has received the posted information. If the terminal reception unit 22 accepts the posted information, the process proceeds to step S402, and if not, the process proceeds to step S403.

(Step S402) The terminal transmission unit 24 transmits the posting information to the posting information processing device 1 in pairs with the user identifier. After that, the process returns to step S401.

(Step S403) The terminal processing unit 23 determines whether or not the terminal receiving unit 25 has received the posted information. If the terminal receiving unit 25 receives the posted information, the process proceeds to step S404, and if the terminal receiving unit 25 does not receive the posted information, the process proceeds to step S405.

(Step S404) The terminal output unit 26 outputs the posted information via an output device such as a display. After that, the process returns to step S401.

(Step S405) The terminal processing unit 23 determines whether or not the terminal reception unit 22 has accepted the action for the posted information. If the terminal reception unit 22 accepts the action for the posted information, the process proceeds to step S406, and if not, the process proceeds to step S407.

(Step S406) The terminal transmission unit 24 transmits the action to the posting information processing device 1 in pairs with the user identifier. After that, the process returns to step S401.

(Step S407) The terminal processing unit 23 determines whether or not the terminal reception unit 22 has received an instruction to the link. If the terminal reception unit 22 accepts the instruction to the link, the process proceeds to step S408, and if not, the process proceeds to step S409.

(Step S408) The terminal transmission unit 24 transmits an instruction to the link to the posting information processing device 1 in pairs with the user identifier. After that, the process returns to step S401.

(Step S409) The terminal processing unit 23 determines whether or not the terminal receiving unit 25 has received the auxiliary information. If the terminal receiving unit 25 receives the auxiliary information, the process proceeds to step S410, and if the terminal receiving unit 25 does not receive the auxiliary information, the process returns to step S401.

(Step S410) The terminal output unit 26 outputs the auxiliary information via an output device such as a display. After that, the process returns to step S401.

In the flowchart of FIG. 7, for example, the process starts when the power of the user terminal 2 is turned on, and ends when the power is turned off or an interrupt for the end of the process occurs. However, the trigger for the start and end of processing does not matter.

Hereinafter, a specific operation example of the dialogue system 100 according to the present embodiment will be described. It should be noted that the following description is an example and does not limit the present invention, and it goes without saying that various modifications can be made. In addition, the explanations regarding the above-mentioned matters are simplified or omitted.

The conceptual diagram of the dialogue system 100 is FIG. The organization that operates the dialogue system 100 is a university. The user who uses the dialogue system 100 is a university student. The university has set up an online learning site where students can take classes outside the classroom. Students engage in dialogue such as chat when attending an online learning site using the user terminal 2. The dialogue system realizes a dialogue between two or more users on an online learning site, and supports the dialogue by using auxiliary information such as a video of a lecture in a classroom, user information of similar users, and similar contents.

A term database in which two or more terms with importance are registered is stored in the storage unit 11 that constitutes the posting information processing device 1. The user static profile storage unit 111 stores two or more static profile information including the static profile information of the user XX and the static profile information of the user YY. The storage unit 11 also stores two or more browsing histories including the browsing history of user XX and the browsing history of user XX.

The post information storage unit 113 stores two or more post information posted in the past by two or more users including user XX and user YY.

The user dynamic profile storage unit 112 already stores two or more dynamic profile information generated from the past two or more post information stored in the post information storage unit 113. The two or more stored dynamic profile information includes the dynamic profile information of the user XX and the dynamic profile information of the user YY.

FIG. 8 is an example of a data structure diagram of dynamic profile information. The dynamic profile information corresponds to an ID (for example, 1, 2, ...). The dynamic profile information corresponding to the ID “1” (hereinafter, “dynamic profile information 1”) has one or more pairs of terms and importance corresponding to the user identifier “XX”. The term and importance pair corresponding to the user identifier “XX” is, for example, a pair of the term “ZZ” and the importance “1.1”, a pair of the terms “test range” and the importance “1.6”. , A pair of terms "C programming" and importance "0.7", a pair of terms "test" and importance "1.7", and so on. Similarly, the dynamic profile information corresponding to the ID “2” (hereinafter, “dynamic profile information 2”) has one or more pairs of terms and importance corresponding to the user identifier “YY”. The term and importance pair corresponding to the user identifier “YY” are, for example, a pair of the term “ZZ” and the importance “1.0”, a pair of the term “C programming” and the importance “0.4”. , A pair of terms "test" and importance "1.6", a pair of terms "test range" and importance "1.4", and so on.

Now, user XX and user YY are having a dialogue using the dialogue system 100. First, when the terminal reception unit 22 receives the posting information "C programming difficult" in the user terminal 2 of the user XX, the terminal output unit 26 outputs the posting information "C programming difficult" via an output device such as a display. .. Further, the terminal transmission unit 24 transmits the posted information “C programming difficult” to the user identifier “XX”.

In the post information processing device 1, when the post information receiving unit 121 receives the post information "C programming difficult" in pairs with the user identifier "XX", the post information storage unit 131 sets the post information "C programming difficult" as the user identifier ". It is stored in the posting information storage unit 113 in association with "XX". The dynamic profile information generation unit 133 generates dynamic profile information corresponding to the user identifier by, for example, the following procedure.

The dynamic profile information generation unit 133 refers to the term database and extracts terms from the posted information “C programming is difficult”. "C programming" is registered together with its importance in the term database, and this term "C programming" is extracted together with its importance from the posted information "C programming difficult". The dynamic profile information generation unit 133 acquires the importance of the term "C programming", and further acquires the TF value and the IDF value of the term "C programming" by using, for example, the equations 1 and 2.
[Number 1]

TF = (importance of term i) / (number of posted information in which term i appears)
[Number 2]

IDF = (total number of posted information) / (number of posted information in which term i appears)

Here, the total number of posted information is the total number of one or more posted information corresponding to the user identifier "XX". Further, the number of posted information in which the term i appears is the number of posted information in which the term i appears among one or more posted information corresponding to the user identifier “XX”.

When calculating the number of posted information in which the term i appears, the target posted information is usually all the posted information managed by the posted information processing device 1. However, a part of all the posted information managed by the posted information processing device 1 that meets the conditions (for example, posted information for the past year, posted information during the current dialogue, etc.) may be used. The same applies to the posted information for which the total number of posted information is calculated.

The dynamic profile information generation unit 133 uses, for example, the TF-IDF value obtained by multiplying the TF value and the IDF value obtained in the equations 1 and 2 as a new importance of the term “C programming”. The dynamic profile information generation unit 133 obtains the importance of each of the one or more terms appearing in the one or more posted information corresponding to the user identifier "XX" by the same procedure, and sets the pair of the terms and the importance. To configure. The dynamic profile information generation unit 133 updates the existing dynamic profile information corresponding to the user XX by using the set of the pair of the term and the importance thus constructed.

Alternatively, the dynamic profile information generation unit 133 may use the result calculated by the equation 3 as the dynamic profile information of the user XX, for example.

Here, TF1i is a TF value of the term i extracted from the posted information of user XX. TF2i is a TF value of the term i extracted from a dialogue (a series of posted information) between user XX and user YY. TF3i is a TF value of the term i extracted from the browsing history of user XX.

In Equation 3, TF1i is multiplied by the weight α, TF2i is multiplied by the weight β, TF3i is multiplied by the weight γ, and the three multiplication results are summed to obtain the importance corresponding to the term i. Then, the importance corresponding to each of n + 1 terms from term 0 to term n is totaled to obtain dynamic profile information.

After that, the link generation unit 134 generates a link to the auxiliary information by, for example, the following procedure. First, the link generation unit 134 acquires the user identifier “YY” that identifies the user who receives the posting information “C programming” from the storage unit 11. Next, the link generation unit 134 acquires the dynamic profile information 2 corresponding to the user identifier “YY” from the user dynamic profile storage unit 112. Next, the link generation unit 134 determines whether or not the importance “0.4” of the term “C programming” in the dynamic profile information 2 satisfies the condition.

Here, the conditions are the first condition that the importance of the term is "first threshold value" 1.5 "or more" and the importance of the term is "second threshold value" 0.5 "or less". Including the second article. Since the importance "0.4" of the term "C programming" satisfies the second condition in the link generation unit 134, for example, the link to the auxiliary information identified by the auxiliary information identifier "http: // ... c_programming ..." To generate. The auxiliary information identifier “http: //… c_programming…” may be stored in advance in the storage unit 11 in association with the term “C programming”, or may be stored in advance in the storage unit 11, or may be stored in an external device by a search using a search site. It may be obtained from.

The link generation unit 134 stores the term “C programming” and the auxiliary information identifier “http: //… c_programming…” in the post information storage unit 113 in association with the post information “C programming difficult”. As a result, a link is generated from the term "C programming" that constitutes the posted information "C programming difficult" to the auxiliary information identified by the auxiliary information identifier "http: // ... c_programming ...".

FIG. 9 is a data structure diagram of posted information having a link. The posted information having a link is composed of, for example, a set of posted information, terms, and auxiliary information identifiers. Post information having or not having a link is stored in the post information storage unit 113 in association with an ID (for example, 1, 2, ...).

At this point, the posting information storage unit 113 stores the posting information corresponding to the ID “1” (hereinafter, “posting information 1”). The posted information 1 is composed of a set of posted information “C programming difficult”, the term “C programming”, and an auxiliary information identifier “http: //… c_programming…”. The auxiliary information identified by the auxiliary information identifier “http: //… c_programming…” is considered to be a kind of knowledge support information because the importance of the corresponding term “C programming” is 0.4 or 0.7. You can. The post information transmission unit 141 transmits the post information “C programming difficult” having the link generated in this way to the user terminal 2 of the user YY.

When the terminal receiving unit 25 receives the posted information "C programming difficult" having a link in the user terminal 2 of the user YY, the terminal output unit 26 sends the posted information "C programming difficult" having a link to an output device such as a display. Output via.

As a result, as shown in FIG. 10, for example, the post information “C programming difficult” having no link is displayed on the display of the user terminal 2 of the user XX, while the display of the user terminal 2 of the user YY shows. , The result is that the posted information "C programming is difficult" with a link is displayed.

Subsequently, in the user terminal 2 of the user XX, when the terminal reception unit 22 accepts the posted information "immediate test", the terminal output unit 26 displays the posted information "immediate test" on an output device such as a display. Output via. In addition, the terminal transmission unit 24 transmits the posted information "Soon to be tested" to the user identifier "XX".

In the posted information processing device 1, the dynamic profile information generation unit 133 extracts the term "test" from the posted information "immediate test" and acquires the importance of the term "test" in the same procedure as above. Then, these pairs are used to update the dynamic profile information of user XX. The link generation unit 134 acquires the dynamic profile information of the user YY who receives the posted information "immediate test", and determines whether or not the importance corresponding to the term "test" satisfies the condition. Since the importance "1.6" corresponding to the term "test" satisfies the second condition "first threshold value" 1.5 "or higher", the dynamic profile information generation unit 133 may, for example, use the auxiliary information identifier. Generate a link to the auxiliary information identified by “http: //… kougi_eizou…”. The auxiliary information identifier “http: //… kougi_eizou…” may be stored in advance in the storage unit 11 in association with the term “test”, for example.

At this point, the posting information storage unit 113 stores the posting information corresponding to the ID “2” (hereinafter, “posting information 2”). The posted information 2 is composed of the posted information “Soon to be tested”, the term “test”, and the auxiliary information identifier “http: //… kougi_eizou…”. The auxiliary information identified by the auxiliary information identifier “http: //… kougi_eizou…” is considered to be a kind of interest-raising support information because the importance of the corresponding term “examination” is 1.6 or 1.7. You can. The posting information transmission unit 141 transmits the posting information “coming soon” having the link generated in this way to the user terminal 2 of the user YY.

In the user terminal 2 of the user YY, when the terminal receiving unit 25 receives the posted information "immediately tested" having a link, the terminal output unit 26 displays the posted information "coming soon" having a link. Output via an output device such as.

As a result, for example, as shown in FIG. 10, the post information "immediate test" without a link is displayed on the display of the user terminal 2 of the user XX, while the user terminal 2 of the user YY is displayed. The result is that the display will show the posted information "Soon to be tested" with a link. In addition, for example, the display mode of the posted information on the user terminal 2 of FIG. 10 does not matter. For example, in the user terminal 2 of user XX in FIG. 10, the posted information of user XX (self) may be displayed on the right side of the screen, and the posted information of user YY (other party) may be displayed on the left side of the screen.

After that, when the terminal reception unit 22 receives the posted information "It seems that the test range has been announced" in the user terminal 2 of the user YY, the terminal output unit 26 outputs the posted information "It seems that the test range has been announced" on the display or the like. Output via the device. In addition, the terminal transmission unit 24 transmits the posted information "It seems that the test range has been announced" to the user identifier "YY".

In the posted information processing apparatus 1, the dynamic profile information generation unit 133 refers to the term database in the same manner as above, extracts the term "test range" from the posted information "It seems that the test range has been announced", and extracts the term "test range". The importance of the "range" is acquired, and the dynamic profile information of the user YY is updated using these pairs. When the term "announcement" is registered in the term database, the dynamic profile information generation unit 133 also extracts "announcement" from the posted information "it seems that the test range has been announced", and the link generation unit 134 The same processing is performed for the term "announcement" as follows. However, in this example, it is assumed that only the term "test range" is extracted. The link generation unit 134 acquires the dynamic profile information of the user XX who receives the posted information "It seems that the test range has been announced", and determines whether or not the importance corresponding to the term "test range" satisfies the condition. .. Since the importance "1.4" corresponding to the term "test range" does not satisfy any of the conditions, the link generation unit 134 determines whether or not the term "test range" is a user name. Since the term "test range" is not a user name, the link generation unit 134 calculates the degree of similarity between a series of posted information (contents) and determines whether or not there is similar content similar to the content. Then, when there is similar content, the link generation unit 134 acquires the auxiliary information identifier “http: //… chat_content…” that identifies the auxiliary information corresponding to the similar content, and supplements from the term “test range”. Generate a link to the auxiliary information identified by the information identifier “http: //… chat_content…”. In addition, instead of using the term “test range” as the link source, the link generation unit 134 uses, for example, a button “similar” linked to the auxiliary information identified by the auxiliary information identifier “http: //… chat_content…”. You may generate "I have a chat".

At this point, the posting information storage unit 113 stores the posting information corresponding to the ID “3” (hereinafter, “posting information 3”). The posted information 3 is composed of a set of the posted information "It seems that the test range has been announced", the term "test range", and the auxiliary information identifier "http: // ... chat_content ...". The auxiliary information identified by the auxiliary information identifier “http: //… kougi_eizou…” is a kind of interest-raising support information because the importance of the corresponding term “test range” is 1.4 or 1.6. You may think about it, but it may be classified as knowledge support information. The posting information transmission unit 141 transmits the posting information "it seems that the test range has been announced" having the link generated in this way to the user terminal 2 of the user XX.

When the terminal receiving unit 25 receives the posted information "It seems that the test range has been announced" in the user terminal 2 of the user XX, the terminal output unit 26 receives the posted information "It seems that the test range has been announced" having the link. , Output via an output device such as a display.

As a result, for example, as shown in FIG. 10, the posted information "It seems that the test range has been announced" without a link is displayed on the display of the user terminal 2 of the user YY, while the user terminal 2 of the user XX. The result is that the posted information "It seems that the test range has been announced" with a link is displayed on the display of. The link source is the "test range" in this example, but for example, the above-mentioned button "There is a similar chat" may be used.

After that, when the terminal reception unit 22 receives the posted information "Do you know anyone?" In the user terminal 2 of the user XX, the terminal output unit 26 displays the posted information "Do you know anyone?" With an output device such as a display. Output via. In addition, the terminal transmission unit 24 transmits the posted information "Do you know anyone?" To the user identifier "XX".

In the posted information processing device 1, since the posted manuscript information "Do you know anyone?" Does not include any term in the term database and one term is not extracted, no link to any auxiliary information is generated.

At this point, the posting information storage unit 113 stores the posting information corresponding to the ID “4” (hereinafter, “posting information 4”). The posted information 4 is composed of a set of the posted information "Do you know anyone?", The term "-", and the auxiliary information identifier "-". In addition, "-" indicates that the element does not exist. The post information transmission unit 141 transmits the post information "Do you know anyone?" With the link generated in this way to the user terminal 2 of the user XX.

When the terminal receiving unit 25 receives the post information "Do you know anyone?" That does not have a link in the user terminal 2 of the user XX, the terminal output unit 26 receives the post information "Does anyone know?" That does not have a link. Is output via an output device such as a display.

As a result, as shown in FIG. 10, for example, the posted information “Do you know anyone?” That does not have a link is displayed on both the display of the user terminal 2 of the user YY and the display of the user terminal 2 of the user XX. The result is that

After that, when the terminal reception unit 22 receives the posted information "Ask ZZ" in the user terminal 2 of the user YY, the terminal output unit 26 sends the posted information "Ask ZZ" to an output device such as a display. Output via. Further, the terminal transmission unit 24 transmits the posted information "Ask ZZ" to the user identifier "YY" in pairs.

In the post information processing device 1, the term "ZZ" is extracted from the post information "Ask ZZ", and the importance "1.1" corresponding to the term "ZZ" is acquired from the dynamic profile information 1 of the user XX. Will be done. Since this importance does not satisfy any of the conditions, the link generation unit 134 determines whether or not the term "ZZ" is a user name. Since the term "ZZ" is a user name, the link generation unit 134 calculates the degree of similarity between users by, for example, the number 4, and determines whether or not there is a similar user similar to the user.

In Equation 4, | V | is the number of dimensions of the feature vector (for example, the number of terms registered in the term database), i is a variable indicating the terms in order, and x _i is the i-th regarding user XX. The importance of the term, y _i is the importance of the i-th term with respect to the user YY. When the calculation result of the formula 4 is equal to or more than a predetermined threshold value or larger than the predetermined threshold value, the link generation unit 134 determines that the user YY is similar to the user XX, and the calculation result of the formula 4 is equal to or less than the predetermined threshold value. Alternatively, if it is less than a predetermined threshold, the user YY determines that it is not similar to the user XX. Here, it is assumed that the user YY is not similar to the user XX, but the user AA is determined to be similar to the user XX by the same processing.

Then, when there is a similar user AA, the link generation unit 134 acquires the auxiliary information identifier "AA @ abc ..." That identifies the auxiliary information corresponding to the similar user AA, and the auxiliary information identifier "AA @ abc ..." Generate a button "Mr. AA is similar to you" linked to the auxiliary information identified by ".

At this point, the posting information storage unit 113 stores the posting information corresponding to the ID “5” (hereinafter, “posting information 5”). The posted information 5 is composed of a set of the posted information "Ask ZZ", the term "-", and the auxiliary information identifier "AA @ abc ...". The auxiliary information identified by the auxiliary information identifier “AA @ abc…” is irrelevant to the importance of the term and is usually classified as interest-raising support information.

Further, the auxiliary information transmission unit 142 transmits the auxiliary information "Introduction to C programming" corresponding to the instruction to the link to the user terminal 2 of the user YY who is the transmission source of the instruction.

When the terminal receiving unit 25 receives the auxiliary information "Introduction to C programming" in the user terminal 2 of the user YY, the terminal output unit 26 outputs the auxiliary information "Introduction to C programming" via an output device such as a display. As a result, for example, the auxiliary information "Introduction to C programming" as shown in FIG. 11 is displayed on the display of the user terminal 2 of the user YY. When an action such as pressing "Like" is performed on the screen of the auxiliary information "Introduction to C programming" and the terminal receiving unit 22 accepts the action, the terminal transmitting unit 24 performs the action with the user identifier "YY". And send to pair.

In the posting information processing device 1, when the receiving unit 12 receives an action in pairs with the user identifier "YY", the processing unit 13 associates the action information including the number of times of the action with the user identifier "YY" and stores the storage unit 11. Accumulate in. The action information is used when generating the dynamic profile information of the user YY.

Further, for example, in the user terminal 2 of the user XX, if the terminal reception unit 22 receives an instruction to the link in the posted information "It seems that the test range has been announced" having the link, the terminal transmission unit 24 goes to the link. Is transmitted to the posting information processing device 1 in pairs with the user identifier “XX”.

When the instruction to the link is received by the instruction receiving unit 122 in pairs with the user identifier “XX” in the posting information processing device 1, the browsing history storage unit 132 identifies the auxiliary information, the auxiliary information identifier “http: //… The browsing history having “chat_content” is stored in the storage unit 11 in association with the terminal identifier “XX”. Further, the auxiliary information transmission unit 142 transmits the auxiliary information "similar content" corresponding to the instruction to the link to the user terminal 2 of the user XX who is the transmission source of the instruction.

When the terminal receiving unit 25 receives the auxiliary information "similar content" in the user terminal 2 of the user XX, the terminal output unit 26 outputs the auxiliary information "similar content" via an output device such as a display. As a result, on the display of the user terminal 2 of the user XX, for example, the auxiliary information "similar content" as shown in FIG. 12, that is, a series of posted information similar to the series of posted information shown in FIG. 10 is displayed.
