Abstract

Demographic information and recommendation information of high accuracy are provided, without using the results of for example multi-frequency analysis and weight point analysis, by means of product characteristics. A recommendation response is generated by a combination of items ranked by degree of proximity of the social graph (7) and ranking within conjoint analysis using a social graph (7) of respondents to a recommendation questionnaire, from analysis results summarised beforehand as conjoint analysis results.

Description

Information collection system, information collection method, and program

The present invention relates to a recommendation technique related to purchase of a product, and more particularly, to a technique effective for recommendation information using a social network service.

In sales sites such as the Internet, search technology that naturally displays recommendations for consumers in searches related to actual purchases is incorporated. For example, a recommendation service is widely known as one of the search techniques.

The recommendation service is a service that analyzes consumer preferences and displays information that is likely to be of interest to each consumer (recommendation information). Refers to pre-registered consumer preferences, purchase history, etc. Introduce products and services that seem to meet each taste.

The recommendation information used for the recommendation service is generated based on demographic information including, for example, consumer attribute data (age, gender, income, occupation, etc.), or purchase frequency, purchase history, A technique for generating a purchase amount by performing frequent analysis and priority analysis is known.

In this kind of recommendation technology, information from an information provider is distributed and collected, and information on a desired subject is collected as needed (for example, refer to Patent Document 1). Personalize search results so that word-of-mouth information is ranked high (for example, refer to Patent Document 2), or use a factor database to analyze and present products that are most suitable for consumers (for example, , See Patent Document 3).

Let the information collection system 1) execute it.

Hereinafter, the embodiment will be described in detail based on the above-described outline.

<Configuration example of information collection system>
In the present embodiment, the information collection system 1 includes a recommendation engine 2, a result accumulation storage unit 3, and a conjoint analysis result storage unit 4, as shown in FIG.

The result accumulation storage unit 3 stores the result indicating the intention in the intention survey 5. The intention survey 5 is a survey that is a basis for conjoint analysis, and is composed of question items that investigate the preference and purchase intention of a product that the SNS (social networking service) 6 user wants to investigate, and the result is a social graph. 7 has SNS6.

The social graph 7 is so-called human relationship correlation data, and includes, for example, human relationship data representing a connection between people, human data including personal attributes, and a connection between people, things, and contents. The conjoint analysis is an analysis method for measuring individual effects of factors constituting “thing” from the overall evaluation of “thing”.

The conjoint analysis result storage unit 4 is a collection of information suitable for information retrieval. The recommendation engine 2 receives an inquiry from the sales site 8, and uses the social graph 7 corresponding to the content of the inquiry, and presents recommendation information that matches the closest social graph.

Further, hereinafter, various functions for performing the processing shown in FIGS. 2 to 7 include, for example, software in a program format stored in a program storage memory (not shown) provided in the information collecting system 1. This is realized by execution of a CPU (Central Processing Unit) (not shown) of the system 1.

<Example of purchasing intention survey>
FIG. 2 is a flowchart showing an example of a purchase intention survey for a certain product.

First, it connects to the SNS 6 via a communication line such as the Internet line (step S101), presents the intention survey 5 that is the basis of the conjoint analysis, and makes an opt-in / opt-out inquiry to the intention survey 5 (step S102). .

In the process of step S102, if the SNS 6 user is not permitted, the process ends. If permitted, an inquiry is made as to whether or not the social graph can be provided from the SNS 6 (step S103). If permitted, an answer from the intention survey 5 is accepted (step S104). The answer in the process of step S104 is stored in the result accumulation storage unit 3. If the provision of social graph is not permitted in the process of step S103, the process ends.

<Conjoint analysis and analysis example>
FIG. 3 is a flowchart showing an example of conjoint analysis and analysis.

First, an opt-in person in the investigation shown in FIG. 2 is identified (step S201), and a result corresponding to the intention is read from the result accumulation storage unit 3 for each opt-in unit (step S202).

Subsequently, the social graph 7 possessed by the SNS 6 is read (step S203), and a processing identification code is assigned to the information of the social graph 7 (step S204).

Then, the demographic information is deleted from the social graph 7 to which the process identification code is assigned (step S205), and the social graph 7 is patterned (step S206).

Subsequently, in the patterned social graph 7, the preference and purchase consciousness are ranked, output as a conjoint analysis result (step S 207), and stored in the conjoint analysis result storage unit 4. Thereafter, the processing in steps S202 to S207 is continued until there is no opt-in person for the intention investigation (step S208).

<Example of internal processing of recommendation engine 2>
FIG. 4 is a flowchart showing an example of internal processing of the recommendation engine 2.

First, when a recommendation inquiry from the sales site 8 is received (step S301), an inquiry is made as to the opt-in of using the social graph 7 for the recommendation (step S302). When the use of the social graph 7 is permitted, an inquiry about the social graph 7 is made (step S303), and a plurality of conjoint analysis result inquiries that the social graph 7 approximates are made (step S304).

Then, ranking is performed according to the degree of social graph approximation (step S305), and the recommended ranking is performed according to the rank in the conjoint analysis and the social graph approximation (step S306), and a recommended answer is given (step S306). S307).

<Example of conjoint analysis>
FIG. 5 is an explanatory diagram showing an example of conjoint analysis.

The conjoint analysis result includes a processing identification code 141, a social graph pattern 142, preference information 143, and an analysis social graph 147 as shown in the figure.

The preference information 143 includes preference (1) 144, preference (2) 145, and preference (3) 146 as subordinate information, and the social graph for analysis 147 includes person-to-person connection information 148, person-to-thing as subordinate information. It has connection information 149, connection information 14A between people and content, and correlation information 14B between people, things, and content.

<Example of social graph>
FIG. 6 is an explanatory diagram illustrating an example of a social graph.

The left side of FIG. 6 shows an example of the logical structure of the social graph read from the SNS 6.

In this case, the social graph is composed of “human data” and “behavior history data”.

“Human data” includes data such as “information for identifying a person”, “demographic information”, and “connection between people”. “Information for identifying a person” is, for example, an ID (identification code) and a password. “Demographic information” is information such as age, gender, income, and occupation, for example. “Person-to-person connection” is information about friendship, community participation, affiliated companies, and the like.

Also, the “behavior history data” includes “connections between people and things”, “connections between people and contents”, and “correlation information between people, things, and contents”. The “connection between people and goods” is, for example, recommendation information and purchase information, and the “connection between people and content” is information such as browsing information on the Web and action history in the site. “Correlation information of people, things, and contents” is information obtained by analyzing each connection (people, things, contents, etc.), for example.

The right side of FIG. 6 shows an example of a social graph for analysis used by the recommendation engine 2 when collecting information and retrieving information.

The social graph for analysis is also composed of “human data” and “behavior history data” in the same manner as the social graph read from the SNS 6. “Human data” includes the process identification code 141 assigned in the process of step S204 of FIG.

The person-to-person connection 148 includes information obtained by deleting information for identifying an individual from the “person-to-person connection” information of the “human data” in the social graph on the left side of FIG. Further, “information for identifying a person” and “demographic information” in the “human data” in the social graph on the left side of FIG. 6 are deleted.

In the “behavior history data” of the social graph on the right side of FIG. 6, the connection 149 between people and things, the connection 14A between people and content, and the correlation information 14B between people, things, and content are “behavior” in the social graph on the left side of FIG. It is the same as “History data”.

<Example of social graph patterning>
FIG. 7 is an explanatory diagram showing an example of the social graph pattern 142.

FIG. 7 illustrates the attributes of social links and social link destinations. The patterning of the social graph includes social link attributes {direct | indirect} and social link destination attributes {workmate | community | classmate | ...}. The social graph patterning is realized by digitizing these into a bitmap.

This makes it possible to use the survey results of survey subjects who have an idea close to the purchaser, so that highly accurate recommendations can be made.

Thereby, according to this embodiment, highly accurate recommendation information can be provided to the consumer by performing the recommendation using the social graph excluding the demographic information and the conjoint analysis result.

As mentioned above, the invention made by the present inventor has been specifically described based on the embodiment. However, the present invention is not limited to the embodiment, and various modifications can be made without departing from the scope of the invention. Needless to say.

The present invention is suitable for providing recommendation information on social media.
