  Hereinafter, a mode for carrying out an information processing apparatus, an information processing method, and an information processing program according to the present application (hereinafter referred to as “embodiment”) will be described in detail with reference to the drawings. Note that the information processing apparatus, the information processing method, and the information processing program according to the present application are not limited by this embodiment. In addition, the embodiments can be appropriately combined within a range that does not contradict processing contents. In the following embodiments, the same portions are denoted by the same reference numerals, and redundant description is omitted.

[1. Example of information processing)
First, an example of information processing according to the embodiment will be described with reference to FIG. FIG. 1 is a diagram illustrating an example of information processing according to the embodiment. FIG. 1 shows an example in which the information processing apparatus 100 is a shopping server that functions as an EC (Electric Commerce) site. The information processing apparatus 100 as a shopping server provides information regarding a product or service (hereinafter simply referred to as “product”) to the user, and accepts purchase of the product from the user.

  The information processing apparatus 100 as a shopping server illustrated in FIG. 1 has a review function that accepts postings such as impressions and evaluations about a product by a user who purchased the product. A product review or service review (hereinafter simply referred to as “review”) posted by the user is stored in the product database 121, for example.

  As shown in FIG. 1, the review includes a sentence written by the user who purchased the product. In this sentence, there may be an additional description other than the description about the impression and evaluation of the product.

  For example, in the review shown in FIG. 1, in addition to the description about the impression and evaluation of the product (here, “skin lotion A”), “This product is indispensable for morning and evening care.” , Was introduced on Talent Y's blog. "

  Therefore, in the information processing according to the embodiment, information that links the product with another thing is generated using an additional description described in the review.

  Specifically, the information processing apparatus 100 according to the embodiment first acquires review information stored in the product database 121 (step S1). The review information includes at least text information indicating the content of a sentence written by the user.

  Subsequently, the information processing apparatus 100 extracts a specific proper noun from the acquired review information (step S2). A specific proper noun means a proper noun registered in advance among proper nouns such as a person name, a group name, a title name, and a building name. For example, when “talent Y” is registered as a specific proper noun, the information processing apparatus 100 extracts “talent Y” from text information included in the review information.

  Subsequently, the information processing apparatus 100 generates related information in which the extracted specific proper noun is associated with the product to be reviewed (step S3). For example, the information processing apparatus 100 generates related information in which a specific proper noun “talent Y” extracted from the review is associated with the product “skin lotion A” to be reviewed, and stores the related information in the related database 123.

  As described above, the information processing method according to the embodiment associates a product with a specific proper noun through a “review” posted by the user who purchased the product. As a result, for example, it is possible to generate more appropriate information as information linking the product and other things other than the product, as compared with the case where the specific information is extracted from the weblog or the word of mouth and related information is generated. .

  That is, unlike the weblog where the author can freely determine the topic, the topic described in the review is basically limited to the product. For this reason, when a specific proper noun is included in the review, the specific proper noun is highly likely to be a proper noun that appears in a topic related to a product to be reviewed.

  Also, only information from the user who actually purchased the product is posted in the review. For this reason, compared with a review in which a user who has not purchased a product may post information about rumor, there is a low possibility that information with low reliability will be posted. That is, the review is highly reliable as a target for extracting a specific proper noun.

  Therefore, according to the information processing method according to the embodiment, it is possible to generate appropriate information as information linking a product or service with other things other than the product or service.

  The generated related information can be used for various services on the EC site.

  For example, FIG. 1 shows an example in which related information is used for product search. As illustrated in FIG. 1, when the information processing apparatus 100 receives a search request using “talent Y” as a search keyword from the user terminal 10 (step S <b> 4), the product associated with “talent Y” is related information. The search result is transmitted to the user terminal 10 (step S5).

  Thereby, the user of the user terminal 10 can easily obtain information on the products (here, “skin lotion A”, “supplement B”, “frying pan C”, etc.) associated with “talent Y”. it can. Thus, by using the related information for the product search, for example, the convenience of the search for a user who wants to purchase a product related to a specific proper noun (“talent Y”) can be improved.

  In addition, the information processing apparatus 100 can provide a recommendation function, an advertisement function, and the like using related information, which will be described later.

  Hereinafter, the information processing apparatus 100 that performs such processing and the information processing system 1 including the information processing apparatus 100 will be described in detail.

(About the acquisition unit 131)
The acquisition unit 131 acquires review information from the product database 121 stored in the storage unit 120.

  The acquisition timing of the review information is arbitrary. For example, when new review information is registered in the product database 121, the acquisition unit 131 may acquire the registered new review information from the product database 121. In addition, when the number of review information newly registered in the product database 121 exceeds the threshold, the acquisition unit 131 may acquire a plurality of newly registered review information from the product database 121 in a batch.

  In addition, the acquisition unit 131 may acquire the review information from the product database 121 in a time zone determined in advance as a time zone in which the processing load of the information processing apparatus 100 as a shopping server is reduced, for example. Further, the acquisition unit 131 may acquire the review information from the product database 121 when the number of accesses to the EC site falls below a threshold value. As described above, by obtaining the review information under a situation where the processing load on the information processing apparatus 100 is low, an increase in the processing load on the information processing apparatus 100 associated with the related information generation process can be suppressed. .

(About the extraction unit 132)
The extraction unit 132 extracts a specific proper noun from the review information acquired from the product database 121 by the acquisition unit 131 based on the information stored in the proper noun database 122.

  For example, the extraction unit 132 extracts all proper nouns from text data included in the review information. Then, the extraction unit 132 compares the extracted proper noun with the “name” stored in the proper noun database 122 and extracts the matched proper noun as a specific proper noun.

  At this time, the extraction unit 132 excludes proper nouns (product name, manufacturer name, etc.) included in the product information of the product to be reviewed from the extraction target. That is, the extraction unit 132 does not extract information on the target product itself from the review information. Thereby, useless accumulation of related information can be suppressed.

  The review information does not necessarily include a specific proper noun itself. For example, it is assumed that “Y-chan” which is a nickname of “talent Y” is included in the text data of the review information. Even in such a case, for example, if “Y-chan” is registered in the proper noun database 122 in association with “talent Y”, “talent Y” is extracted by collating the proper noun database 122. It is possible.

  In addition, a part of the name of “talent Y” (for example, only the surname) may be included in the text data. Even in such a case, if the proper noun associated with “talent Y” is included in the text data, for example, “entertainment office P”, the extracting unit 132 determines that “talent” It is also possible to estimate by extracting “Y”.

(About the generator 133)
The generation unit 133 generates related information in which the specific proper noun extracted by the extraction unit 132 is associated with the product to be reviewed.

  For example, the generation unit 133 displays the proper noun ID of the specific proper noun extracted by the extraction unit 132, the product ID of the product to be reviewed, the number of generations (“1” in the case of new registration), and the generation history. It is stored in the related database 123 in association with the related ID. When related information including the same product ID and proper noun ID is already stored in the related database 123, the generation unit 133 performs a process of updating the generation count and generation history of the relevant information.

  Further, the generation unit 133 calculates a relevance score for the generated related information. For example, the generation unit 133 calculates a relevance score based on the number of generations stored in the related database 123 so that the relevance increases as the number of generations increases.

  Further, the generation unit 133 may calculate the relevance score by weighting the basic score calculated based on the number of generations according to the generation date and time included in the generation history stored in the related database 123. Good. For example, the generation unit 133 increases the relevance score as the related information includes more generation history with new generation dates and times. Moreover, the production | generation part 133 may delete the old production | generation history produced | generated before the set period (for example, 1 year) from the related database 123, and may reduce the frequency | count of production | generation by the number of the production | generation history deleted.

(About the reception unit 134)
The accepting unit 134 accepts various requests and information from the user terminal 10, the store terminal 20, and the advertiser terminal 30.

  For example, the reception unit 134 receives a search request including a search keyword from the user terminal 10. The search request includes a “product search request” for searching for a product at the EC site and a “web search request” for searching the web at the search site.

  In addition, the reception unit 134 receives a purchase request for a product from the user terminal 10. In addition, the reception unit 134 receives information on a specific proper noun and an interest score as information about the user from the user terminal 10.

  In addition, the reception unit 134 receives product information from the store terminal 20 or receives information related to advertisement content from the advertiser terminal 30. The reception unit 134 passes the received information to the registration unit 135, the search unit 136, and the provision unit 137.

(Registration unit 135)
The registration unit 135 registers information received by the reception unit 134 in various databases in the storage unit 120.

  For example, when registration information of a specific proper noun and interest score is received from the user terminal 10, the registration unit 135 corresponds to a proper noun ID and an interest score that identify the specific proper noun received. Are registered in the user database 124 in association with the user ID.

  In addition, when related information is generated by the generation unit 133, the registration unit 135 specifies the user ID of the user who posted the review that is the generation source from the product database 121, and specifies the corresponding user ID. The proper noun ID of the proper noun is related.

  In addition, the registration unit 135 identifies a product that the user has purchased in the past from the purchase history of the product by the user, identifies a specific proper noun associated with the identified product from the related database 123, and associates it with the corresponding user. May be.

  Further, the registration unit 135 may calculate an interest score according to the number of posting reviews including a specific proper noun and register it in the user database 124. For example, when the user identified by the user ID “H1” has posted reviews including a specific proper noun identified by the proper noun ID “M1” five times in the past, the registration unit 135 displays the user ID “H1”. The interest score “5” is stored in the user database 124 in association with “H1”. On the other hand, when the user identified by the user ID “H1” has posted a review including the specific proper noun identified by the proper noun ID “M2” only once in the past, the registration unit 135 displays the user ID The interest score “1” is stored in the user database 124 in association with “H1”. Thus, the registration unit 135 may calculate the interest level score so that the degree of interest increases as the number of postings of reviews including a specific proper noun increases.

  In addition, the registration unit 135 stores the product information transmitted from the store terminal 20 in the product database 121 or stores the review information transmitted from the user terminal 10 in the product database 121 in association with the product ID of the corresponding product. Or Further, the registration unit 135 stores, in the advertisement database 126, information related to the advertisement content transmitted from the advertiser terminal 30.

(About the search unit 136)
The search unit 136 performs a search based on the search keyword included in the search request transmitted from the user terminal 10.

  When the search request transmitted from the user terminal 10 is a product search request, the search unit 136 performs product search using the product database 121.

  Here, when the search keyword is a specific proper noun, the search unit 136 searches for a product associated with the specific proper noun that is the search keyword.

  Specifically, the search unit 136 specifies a proper noun ID for identifying a specific proper noun that is a search keyword using the proper noun database 122, and sets the product ID associated with the specified proper noun ID to the related database 123. Use to specify. Then, the search unit 136 extracts the product information of the specified product ID from the product database 121.

  For example, when the search keyword is a specific proper noun “talent Y”, the search unit 136 specifies the proper noun ID “M1” of “talent Y” using the proper noun database 122. Then, the search unit 136 identifies the product IDs “C1” and “C2” associated with the proper noun ID “M1”, and extracts the product information of the product ID “C1” and the product ID “C2” from the product database 121. To do.

  Then, the search unit 136 passes the search result including the extracted product information to the providing unit 137. At this time, the search unit 136 may generate a search result in which the extracted product information is arranged in the order of the score of the relevance score, and pass the result to the providing unit 137.

  Thus, by using related information, for example, a new product search service that provides a product associated with a celebrity as a search result in response to a product search request using the name of the celebrity as a search keyword is provided. be able to.

  When the search keyword is a product name, the search unit 136 performs a product search using the product name as a search keyword. In this case, the search unit 136 specifies a specific proper noun associated with the product that matches the search keyword using the related information, and suggests the relationship between the specified specific proper noun and the product that matches the search keyword. Information to be added may be added to the search result.

  For example, when the search keyword is the product name “skin lotion A”, the search unit 136 extracts product information corresponding to “skin lotion A” from the product database 121. Here, it is assumed that the product information of the product ID “C1” is extracted. Subsequently, the search unit 136 specifies the proper noun IDs “M1” and “M2” of the specific proper nouns associated with the product ID “C1”, and the specific proper noun identified by the proper noun ID “M1”. The name “program X” of the unique proper noun identified by the name “talent Y” and the proper noun ID “M2” is extracted.
