Abstract

The invention provides a data retrieval apparatus which includes a sensibility database 2 for storing a plurality of title names, evaluation points on a plurality of evaluation items, and identifiers assigned to evaluators responsible for the evaluation points; an evaluation point input block 1 for accepting an evaluation on each of the plurality of evaluation items; an evaluation point correction process block 5 for correcting each of the evaluations accepted by the evaluation point input block 1 by using a plurality of evaluator difference data for each of the plurality of evaluators; a retrieval criteria generating process block 6 for selecting a title name from the sensibility database 2 on the basis of each corrected evaluation; and a data retrieval process block 7. With this data retrieval apparatus, flexible data retrieval can be conducted by just entering subjective evaluation points even for objects from which objective numeric values related to subjective evaluation criteria are difficult to extract.
