PROBLEM TO BE SOLVED: To appropriately determine a relevancy present between persons based on description of a text. SOLUTION: The system for evaluating a relevancy between persons comprises a relevancy detection means detecting, based on a text expressing a certain person's evaluation or emotion for the other person, a relevancy to the other person concerned by the person concerned; a storage means storing the detected relevancy; an evaluation means evaluating, for a set of a first person and second person that is an object of evaluation, the relevancy between the first person and the second person based on a plurality of relevancies extending from the first person to the second person through at least one person, including the stored relevancy; and an output means outputting the evaluated relevancy.

PROBLEM TO BE SOLVED: To estimate a location, with high accuracy, based on the strengths of the radio waves received from a plurality of access points. SOLUTION: A label propagation method is used for estimating position. In particular, this high-accuracy position estimation method robust against the fluctuations of the radio wave intensity is attained, by using a q norm (0

PROBLEM TO BE SOLVED: To more efficiently retrieve a keyword used with high frequency in a text satisfying predetermined conditions than a conventional manner. SOLUTION: This system is stored with a first index for designating the list of keywords included in a text from the identification information of each text, a second index for designating the list of texts including the keywords from the identification information of each keyword and the number of texts including each keyword. Then, when accepting the input of text retrieval conditions, the estimation of a retrieval time based on the first index and the estimation of a retrieval time based on the second index are calculated, and which of the first index and the second index should be used for achieving much quicker retrieval is determined. Then, the keywords appearing with high frequency are retrieved based on the index determined to be used for quicker retrieval in the text satisfying the text retrieval conditions.

PROBLEM TO BE SOLVED: To provide a method, apparatus and computer program for efficiently calculating keyword appearance frequency ranking in distributed processing with a plurality of computers.SOLUTION: Keywords which do not overlap each other are assigned to n computers, where n is a natural number. From the keywords assigned to each computer, keywords of the highest frequency ranks are acquired. From all the acquired keywords, k keywords of the highest overall frequency ranks are selected, where k is a natural number. In doing this, probability P(n, k, t) that the keywords of the highest frequency ranks in each computer are selected as the k highest overall frequency ranks is calculated, where t is a natural number satisfying t
Abstract:
PROBLEM TO BE SOLVED: To provide a technology for retrieving documents matching a dependency pattern at a high speed from a large volume of text documents. SOLUTION: An index creation part creates an index for acquiring by sequential access the array of appearance information (document ID, position on tree) of a node even from each word appearing as the node of the tree of a syntax analytic result. A query input part receives a query from a user or an external application. The query is configured of a retrieval pattern, a pivot (node as the reference of retrieval pattern extension), the maximum depth difference in the case of retrieving an extended node form the pivot, the maximum number of extended nodes to be presented in the order of frequency and a flag designating whether to retrieve the high rank node. The index reading part obtains the appearance information array of the pivot at a place matched with the retrieval pattern. The retrieval is performed until it reaches any node connecting the route to the pivot. COPYRIGHT: (C)2009,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To suitably detect liking expression indicating people's liking for a commodity or the like. SOLUTION: An expression detection system for detecting liking expression indicating evaluator's liking to a specific evaluation target from texts in which the evaluation of the specific evaluation target is described stores a plurality of texts in which the evaluation of the specific evaluation target is described corresponding to the attributes of respective texts, extracts the evaluation expression indicting the evaluation of the specific evaluation target from respective texts, judges whether the extracted evaluation expression is positive polarity indicating positive evaluation to the specific evaluation target or negative polarity indicating negative evaluation to the specific evaluation target, inputs the attribute of a text specified as an object for detecting liking expression, detects evaluation expression detected from the text having the inputted attribute as liking expression, and then outputs the liking expression corresponding to the frequency of judgement that the liking expression in the text having the attribute is positive polarity or negative polarity.

Abstract:
PROBLEM TO BE SOLVED: To provide a technique that makes it possible to list a set of corresponding terms in a different language using a random walk technique with a reasonable calculation amount even when a large number of terms are targeted.SOLUTION: The method comprises the steps of: creating a technical term set of a first language (e.g., Japanese), a general term set of the first language, a technical term set of a second language (e.g., English), and a general term set of the second language; creating a bipartite graph for each of the first and second languages by connecting the technical term set and the general term set of the language with links based on corpus information; creating links between the general terms using a translation dictionary associating general terms between the two languages (e.g., an English-Japanese dictionary) to create a bipartite graph connecting the general term sets of the two languages; creating an association matrix M based on weighted information of links of the bipartite graphs within each language and between the two languages; and calculating a similarity matrix Q defined by Q=(1-c)(I-cM).
Abstract:
PROBLEM TO BE SOLVED: To calculate the matching score of a sentence relative to a query pattern having a modification structure.SOLUTION: An information processor 100 of the invention includes: an input section 110 for obtaining, as input, an analysis object sentence 150, a query pattern 160 and an index value 170 indicating modification easiness between language units in the sentence; and a score calculating section 120 for calculating a matching score indicating to what extent the sentence matches the query pattern by expressing it as a function including at least, as variables, each index value corresponding to each modification relation included in the query pattern 160. The score calculating section 120 tries to associate a partial structure of the query pattern and a range of the sentence while storing the result of partial calculation of the function in a storage area 130 for reuse, and performs calculation recursively in relation to the partial structure and within the range so as to calculate the score.
