摘要:
A relationship information expansion apparatus capable of acquiring a new relationship based on a relationship information piece including two or more language expressions having a semantic relationship is provided. The relationship information expansion apparatus generates a candidate expanded relationship information piece in which at least one language expression included in the relationship information piece was replaced with a similar language expression, and acquires a score that indicates a probability that the candidate expanded relationship information piece has a semantic relationship. The relationship information expansion apparatus selects an expanded relationship information piece, which is a candidate expanded relationship information piece having a high score among candidate expanded relationship information pieces.

Conventionally, it has been impossible to appropriately acquire word pairs having a prescribed relationship. Such word pairs can be appropriately acquired with a word pair acquisition apparatus including: a word class information storage unit in which word class information can be stored; a class pair favorableness degree storage unit in which a class pair favorableness can be stored; a seed pattern storage unit in which can be stored one or more seed patterns; a word pair acquisition unit that acquires one or more word pairs co-occurring with the seed pattern from sentence groups; a class pair favorableness degree acquisition unit that acquires a class pair favorableness degree; a score determination unit that uses the class pair favorableness degree to determine a score of each of the word pairs; and a word pair selection unit that acquires one or more word pairs having a high score.

An information retrieval service system 40 includes: a storage device 64 for storing a question corpus; a clustering unit 100 clustering the questions and determining a prototype of each cluster; an auctioning unit 104 executing auctions for the prototypes; an updating unit 112 associating each of the questions with a winning bidder of the prototype sentence of the cluster to which the question belongs; a question-URL correspondence DB 68 storing, for each of the questions, a URL designated by the winning bidder; a question-searching unit 132 receiving a search request and searching for a question having the shortest distance to the search request; and URL searching units 134, 136 and a query issuing unit 138, transmitting the query generated from the search request to the URL corresponding to the searched out question and transmitting resulting information to an information service using terminal 48.
