Information retrieving system

Abstract

A user speech analyzing component poses, to a user, question sentences for respective ones of a plurality of attributes, and analyzes an attribute value for each of the attributes from an answer sentence from the user to the sentence question. A user data holding component, as a result of analysis, holds user data that allows the plurality of attributes, and respective user attribute values for the attributes to correspond to one another. A matching component, when an acquisition ratio of the attribute values from the user with respect to all of the attributes is a predetermined value or greater, selects at least one target data candidate that matches each of the attributes and each of the attribute values of the user data, from a plurality of target data. A dialogue control component outputs each of the target data candidates selected, to the user's side.

Description

technical field [0001] The present invention relates to a device included in an information retrieval system, a method applied to the information retrieval system, and a storage medium storing a program. Background technique [0002] With the development of the information society, information analysis technology and information retrieval technology for finding necessary information from a large amount of diverse information existing on the Internet are not limited to the information industry, but have become flexible technologies related to communication, media, advertising, content, distribution, etc. The application of information is an important topic directly linked to strengthening competitiveness in all industries. [0003] Various systems, such as Google (registered trademark) and Yahoo (registered trademark), have already been put into practical use as information analysis / information retrieval systems for searching information existing on the Internet. [0004] In...

Problems solved by technology

[0017] In order to carry out this kind of action in the above-mentioned system, there is the following problem in the dialogue with the user: how to carry out the dialogue? What kind of topics are brought up? How to form a sense of trust and security with users?

Therefore, the naturalness of dialogue cannot be fully guaranteed

[0027] In addition, in a step-by-step search device, several utterances (categories of inquiries to the user) are prepared for the purpose of obtaining information from the user, and the system needs to change the topic predominantly. However, in conventional devices, utterances from the system It is a "response to the user's utterance" or "simple agreement", and there is no disclosure or suggestion on how to make the system change the topic dominantly

[0028] Also, in conventional devices, only the vocabulary used by the user is used, and the response becomes monotonous

[0029] Moreover, in the existing device, when there is neither predicate nor case element, a simple echo ("oh" or "really?") appears alone, and the expression of intimacy is not strong
