Next, an example of the information proposal method of this embodiment will be described with reference to the flowchart of FIG. The information proposal method of this embodiment is implemented as follows using the information proposal system apparatus 100 of FIG. 1, for example. In addition, the information proposal method of this embodiment is not limited to use of the information proposal system device 100 of FIG. FIG. 4 is a flow chart showing an example of processing (S1 to S6) of the information proposal system device 100. As shown in FIG.

First, prior to processing by the information proposal device 10 , the user inputs the user's posted information through the input unit 21 of the information proposal terminal 20 . Then, the information proposal terminal 20 transmits the posted information to the information proposal device 10 via the communication line network 30 by the communication unit 22 . The posted information is not particularly limited, and may be, for example, text information or voice information. When the posted information is voice information, for example, text information can be generated from the voice information using a known voice recognition system, and the generated text can be transmitted to the information proposal device 10 as the posted information. . In the following explanation, it is assumed that the user has posted text information such as "It's hot today, so I want to drink slowly. Ideally, a private room with Japanese food. It shouldn't be too expensive." I'll give it to you and explain.

Next, the user's posted information is acquired by the posted information acquiring unit 11 (S1, posted information acquiring step). The post information can be obtained via the communication network 30, for example.

Next, the posted information is analyzed by the posted information analysis unit 12 to extract posted terms (S2, posted information analysis step). The processing by the posted information analysis unit 12 can be performed by, for example, known natural language processing means, and examples thereof include morphological analysis, syntactic analysis, semantic analysis, contextual analysis, anaphoric analysis, and discourse analysis. Processing by the posted information analysis unit 12 will be specifically described using Table 1. As shown in Table 1, the posted information analysis unit 12, for example, from the posted information posted by the user, "It's hot today. Posted terms such as “today”, “hot”, “slowly”, “want to drink”, “Japanese food”, “private room”, “ideal”, “not expensive” are extracted. When there are a plurality of extracted posted terms, for example, the plurality of posted terms may be extracted as a posted term group corresponding to the posted information.

Next, the related term generating unit 13 generates a posted related term related to the posted term (S3, related term generating step). The generation of the post-related terminology by the related terminology generation unit 13 is performed, for example, by preparing a database (external DB 40) of post-related terminology associated with each of the posted terminology included in the group of posted terminology, and communicating the terminology. It can be implemented by extracting post-related terms associated with each posted term from the database via the line network 30 . The posted term and the related term may be associated in a 1:1 relationship, or may be linked in an n:n relationship, for example. The above-mentioned "linked in an n:n relationship" means, for example, when one posted term is linked to a plurality of related terms, and for a plurality of posted terms, one related term This includes cases where the The posted term and the related term are preferably associated with each other in an n:n relationship. For example, when there are a plurality of posted related terms associated with each of the posted terms, the related term generating unit 13 may extract all or part of the posted terms. Further, when the information proposing device 10 includes the storage section, for example, the posting-related term associated with the posted term may be stored in the storage section. In this case, the related term generating unit 13, for example, instead of the database, extracts the posted related term from the storage unit and generates a posted related term related to the posted term.

Processing by the related term generation unit 13 will be specifically described with reference to FIG. Related term generation unit generates posted terms such as “today”, “hot”, “slowly”, “want to drink”, “Japanese food”, “private room”, “ideal”, “not expensive” extracted in S2. 13 extracts post-related terms corresponding to each posted term from an external database via communication network 30, and generates post-related terms. As shown in FIG. 5, the related term generation unit 13 extracts, for example, “pool”, “bath”, “hot spring”, “shower”, and “alcohol” as post-related terms corresponding to “hot”. Then, extract "manga cafe" and "cafe" as post-related terms corresponding to "slowly", and extract "alcohol" and "nutrition drink" as post-related terms corresponding to "I want to drink", Extracted "restaurant" and "kaiseki cuisine" as post-related terms corresponding to "Japanese food", and extracted "quiet", "small number of people", and "spacious" as post-related terms corresponding to "private room", It is possible to extract "reasonable" as a post-related term corresponding to "not expensive" and generate these as the post-related term of the posted information.

Next, the proposal-information-related term extraction unit 14 extracts a proposal-information-related term that matches the posted-related term (S4, proposal-information-related term extraction step). Extraction of proposal information-related terms that match the post-related terms is performed, for example, by preparing a database (external DB 40) of proposal information-related terms that are pre-associated with the post-related terms, and Then, the proposed information-related term corresponding to each post-related term is extracted from the database. The post-related terms and the proposal information-related terms may be associated in a 1:1 relationship, or may be associated in an n:n relationship, for example. is preferably associated with. For example, if there are a plurality of proposal information-related terms associated with each of the posted-related terms, the proposal information-related term extraction unit 14 may extract all or part of them. good. Further, when the information proposal device 10 includes the storage unit, for example, the storage unit may store the proposal information-related terms associated with the posted-related terms. In this case, the proposal information-related term extraction unit 14 extracts the proposal information-related term from the storage unit instead of the database, for example.

The proposal information-related term is a term related to attribute information of proposal information. The suggested information-related terms are also called Yurufuwa category, for example. The attribute information of the proposal information is, for example, not particularly limited, and includes various types of information that the proposal information has. When the proposal information is, for example, information about a restaurant, the attribute information includes, for example, the number of seats, the presence or absence of private rooms, whether or not smoking is allowed, whether children are allowed, whether or not foreign languages are supported, and the region, budget, and credit. Information such as whether or not the card can be used and the types of meal menus can be given.

As a specific example of the proposal information-related terms, the proposal information is information about a restaurant, and the proposal information includes the presence or absence of private rooms, whether smoking is allowed, whether children are allowed, whether foreign languages are supported, budget, credit card usage, etc. A case will be explained by taking as an example a case in which information on usability is associated as attribute information of the proposal information. In this case, proposal information-related terms related to each attribute information include a group of terms shown in FIG. Examples include “private room” and “tight”, and terms related to the attribute information of “private room with sunken kotatsu” include “private room”, “relaxed”, and “Japanese style”. Proposal information related to the attribute information "OK" include "noisy", "family", "children", "baby", etc. Related proposal information-related terms include "Asia", "multilingual", "Chinese", etc. Proposal information-related terms related to the attribute information "average budget ¥ 1000 to ¥ 3000" include: "Reasonable", "Cheap", "Quick", "Feel free", etc., and proposal information-related terms related to the attribute information "Credit card accepted" include "Credit card", "No cash", etc. Examples of proposal information-related terms related to the attribute information of "average budget ¥3,000 to ¥20,000" include "rich", "part", etc., and the attribute "credit card cannot be used" Proposal information-related terms related to information include "cache" and the like.

Next, the proposal information extraction unit 15 extracts the proposal information including the attribute information related to the proposal information related terms (S5, proposal information extraction step). The extraction of the proposal information by the proposal information extraction unit 15 is performed, for example, from an external database (for example, the external DB 40) that stores the relationship between the proposal information-related term and the attribute information of the proposal information, via the communication network 30. to extract the attribute information related to the extracted proposal information-related term, and extract the proposal information including the extracted attribute information from the database in which the attribute information of the proposal information is recorded. For example, if there are multiple proposal information that includes the corresponding attribute information, the proposal information extraction unit 15 may extract all proposal information or extract a part of it.

Next, the output unit 16 outputs the extracted proposal information (S6, output step), and ends the processing by the information proposal device 10 (END).

Then, the terminal 20 of the user receives the output proposal information via the communication network 30 by the communication unit 22 and displays the proposal information on the display unit 23 . When there is a plurality of pieces of proposal information that have been output, the display unit 23 may display, for example, all of the plurality of pieces of proposal information, or may display some of them. In addition, the terminal 20 may also display an avatar (also referred to as a virtual friend) on the display unit 23, for example, and display the proposal information in the form of a proposal by the virtual friend.

According to this embodiment, it is possible to propose information belonging to a related term that matches a term related to a posted term included in user's posted information. Therefore, according to the present invention, a wide range of information can be provided to the user.

In the present embodiment, information stored in the external DB 40 is used for post-related terms and proposal information-related terms, but the present invention is not limited to this. Alternatively, attribute information of proposal information may be analyzed to generate post-related terms and proposal information-related terms. Specifically, first, terms related to posts and terms related to proposal information are defined in advance. Next, the posting terms and the posting-related terms are associated, and the posting terms and the posting-related terms are mapped. Similarly, the attribute information of the proposal information and the proposal information-related terms are associated with each other, and the attribute information of the proposal information and the proposal information-related terms are mapped. Then, for example, using the mapped data as teacher data, AI (Artificial Intelligence) performs supervised learning to determine the relationship between the posted term and the post-related term, and the attribute information of the proposal information and the proposal information-related term. to learn. After that, based on the learned information, AI analyzes the attribute information of the posted term or the proposed information, and generates the posted related term or the proposed information related information.

In this case, for example, the related term generation unit 13 of the information proposal device 10 includes the AI function. The information proposal device 10 may further include, for example, a proposal information analysis unit and a proposal information related term generation unit. The proposal information analysis unit, for example, analyzes the proposal information and extracts attribute information of the proposal information. The processing of the proposed information analysis unit is the same as the processing of the posted information analysis unit 12 except that the suggested information is used instead of the posted information of the user, and the description thereof can be used. Also, the proposal information-related term generation unit generates, for example, proposal information-related terms related to the attribute information. The suggested information related term generation unit includes, for example, the function of the AI. The processing of the suggested information-related term generation unit is the same as the processing of the related information generation unit 13 except that the attribute information is used instead of the posted information, and the description thereof can be used. Also, the central processing unit 101 of the information proposal device 10 functions as, for example, the proposal information analysis unit and the proposal information related term generation unit.

The input of the reaction information may be, for example, actively input by the user, or passive input.

Next, the reaction information acquisition unit 17 acquires the reaction information via the communication network 30 (S11, reaction information acquisition step).

Next, the matching score calculation unit 18 calculates a matching score between the post-related term and the proposal information-related term based on the reaction information (S12, matching score calculation step). Specifically, for example, when the user's reaction information includes information of a positive reaction to the output proposal information, the matching score calculation unit 18 performs matching between the post-related term and the proposal information-related term. Add score. The positive reaction information includes, for example, information of a positive contribution to the proposal information, information of accessing the proposed information (clicking on the URL included in the proposal information), and the like. For example, when the reaction information includes posted information for the proposal information, the posted information analysis unit 12 of the information proposal device 10A may analyze the posted information included in the reaction information and extract posted terms. In this case, the matching score calculation unit 18, for example, determines whether or not the posted term extracted from the reaction information includes positive reaction information, and if the posted term includes positive reaction information , the matching score can be added.

Further, for example, when the user's reaction information includes information of a negative reaction to the output proposal information, or when the reaction information could not be acquired, the matching score calculation unit 18 calculates the post-related terms and A process of reducing the matching score with the suggested information-related term or doing nothing may be performed. The information on the negative reaction includes, for example, information on a negative contribution to the proposal information. For example, when the reaction information includes posted information for the proposal information, the posted information analysis unit 12 of the information proposal device 10A may analyze the posted information included in the reaction information and extract posted terms. In this case, the matching score calculation unit 18, for example, determines whether or not the posted term extracted from the reaction information includes negative reaction information, and if the posted term includes negative reaction information and In at least one case where no positive response is included, the matching score can be deducted or nothing can be done.

Next, the output unit 16 associates and outputs the post-related term, the proposal information-related term, and the matching score (S13, matching score output step), and ends the process (END). For example, when the information proposal device 10A includes a storage unit, the output information may be stored in the storage unit, or may be output to an external database (external DB 40) via the communication network 30, An external database may store.

Then, when performing S1 to S6 from the next time onward, in S4, based on the matching score, a proposal information related term that matches the posted related term is extracted. By processing in this way, based on the reaction information of the user, the accuracy of matching between the post-related term and the proposal information-related term is evaluated, and the proposal information-related term that matches the post-related term is extracted. can be improved, information can be proposed to the user with higher accuracy.
