Patent Searching and Data


Title:
【発明の名称】データベースのマッチング方法
Document Type and Number:
Japanese Patent JP2821213
Kind Code:
B2
Abstract:
PURPOSE:To improve matching rate among a large number of data bases by separating a key word to a common noun part and a proper noun part, generating a rule to estimate a synonym of production format, a rule to estimate an elliptical word, and a rule combining those rules, and estimating a large number of key words for matching processing. CONSTITUTION:A common noun separation part 102 divides an inputted matching key into the proper noun part and the common noun part, and performs inference on the synonym of the common noun part and that of the proper noun part with common noun and proper noun inference parts 104, 106, respectively. Next, the optimum combination of the synonyms of the common and proper noun parts inferred respectively with a combination inference part 108 is obtained, and a matching key candidate to perform the matching processing with the data base is inferred. Finally, the partial matching processing of the candidate of the matching key and the content of the data base is performed, then, the final matching result can be obtained. Thereby, it results that a large number of candidate key words to compensate ambiguity between the key words targeted as coupling processing can be inferred, which improves a coupling ratio between the data bases.
