Information search apparatus and method, and computer readable memory
First Claim
1. A data processing apparatus for searching information based on an input query word, comprising:
- first search means for determining a query keyword on the basis of the input query word, and searching the information by comparing the query keyword with a content keyword expressing a content of the information, wherein the content keyword is stored in association with the information;
second search means for determining a feature amount corresponding to the input query word, and searching the information by comparing the determined feature amount with a feature amount extracted from the information; and
generation means for generating search result information based on both results obtained by said first and second search means; and
acquisition means for acquiring a contrary associative word indicating an antithetic concept of the input query word,wherein said first search means lowers a search matching level of an image found by search using the contrary associative word acquired by said acquisition means.

Abstract
A search request input processing unit holds an input query word in a query word holding unit. An associative word unfolding processing unit acquires associative words in association with the query word held in the query word holding unit with reference to an associative word dictionary. An image content search processing unit using associative words makes a keyword search of image information on the basis of the obtained associative words and the query word. A sensory pattern unfolding processing unit obtains the query word and sensory patterns corresponding to associative words of the query word, and searches image information using feature amounts of the obtained sensory patterns. A search result integration processing unit integrates the search results obtained by the image content word search processing unit and sensory pattern search processing unit.

7. A data processing apparatus implemented information search method for searching information based on an input query word, comprising:
-
a first search step of determining a query keyword on the basis of the input query word, and searching the information by comparing the query keyword with a content keyword expressing a content of the information, wherein the content keyword is stored in association with the information; a second search step of determining a feature amount of a pattern corresponding to the input query word, and searching the information by comparing the determined feature amount with a feature amount extracted from the information; and a generation step of generating search result information based on both results obtained in the first and second search steps; and an acquisition step of acquiring a contrary associative word indicating an antithetic concept of the input query word, wherein said first search step lowers a search matching level of an image found by search using the contrary associative word acquired in said acquisition step. - View Dependent Claims (8, 9, 10, 11, 12)

13. A computer readable memory for storing a computer program for searching information based on an input query word, the computer program comprising:
-
code for a first search step to determine a query keyword on the basis of the input query word, and to search information by comparing the query keyword with a content keyword expressing a content of the information, wherein the content keyword is stored in association with the information; code for a second search step to determine a feature amount corresponding to the input query word, and to search information by comparing the determined feature amount with a feature amount extracted from the information; and code for a generation step to generate search result information based on the results obtained in the first and second search step; and code for an acquisition step to acquire a contrary associative word indicating an antithetic concept of the input query word, wherein said first search means lowers a search matching level of an image found by search using the contrary associative word acquired in said acquisition step.
