APPARATUS FOR SELECTING OPTIMUM DATABASE USING MAXIMAL CONCEPT-STRENGTH RECOGNITION TECHNIQUE AND METHOD THEREOF

摘要

The present invention comprises: a dispersive database in which documents are classified and stored according to a document classification system and document characteristics including term properties; a maximal concept-strength decision unit which extracts features from a target document to be classified when receiving the target document, decides a category of the target document by calculating a weight of each feature using the extracted features and similarity in category, and decides as a maximal concept-strength a maximum value obtained by calculating the weight of each feature with respect to the category of the document; and a database selection unit which selects the dispersive database similar to the characteristics of the target document by applying the maximal concept-strength of the target document decided through the maximal concept-strength decision unit to the dispersive database.
