PROBLEM TO BE SOLVED: To permit data mining even when the same record has text data. SOLUTION: When the retrieval conditions of 'age older than 20 and the sex of female' are inputted, on the basis of the retrieval conditions, a record having data in a numerical data field matched to these retrieval conditions is extracted (step S3). When an analyzing instruction for extracting the term of highest appearance frequency by using the data of the extracted record is inputted (step S5), on the basis of such an instruction, mining processing is performed (step S7). In this case, since the term of 'unemployment' has the highest appearance frequency, it can be guessed a woman older than 20 is interested in unemployment.
