Kind Code:

Abstract:
PURPOSE:To reduce the retrieval noise for document information retrieval by subjecting the result of character string collation to morpheme analysis and discriminating whether a character string coinciding with a collation character string is included in morphemes or not and deleting sentences which do not include it. CONSTITUTION:Retrieval of documents related to fire is inputted to a retrieval condition input device 1 as a retrieval condition, and the collation character string at this time is defined as 'fire'. Two documents, namely, an example 1 'The fire at last night is immediately extinguished.' and an example 2 'A series of cases of fire due to arson are solved.' are stored in a storage device. When receiving the collation character string 'fire' from the device 1, a retrieving device 3 collates it with character strings of documents in the device 2. Collation results in success with respect to both of examples 1 and 2. Collation results are sent to a storage device 4, and sentences which succeed in collation are stored. A morpheme analyzing device 5 subjects documents stored in the device 4 to morpheme analysis to recognize that the collation character string 'fire' is included in morphemes, and the results are stored in a secondary result storage device 7, and retrieval results are displayed on a display device 8.
