PROBLEM TO BE SOLVED: To provide a system which can quickly obtain targeted content with a simple operation. SOLUTION: Two sheets from the head of extracted metadata lined up based on preliminarily fixed order are displayed on the upper and lower columns of the display part of a client, when content on the Internet is retrieved. The upper column of the display part is formed at a reference data display part, and the lower column of the display part is formed at a comparison data display part. The client compares extracted data displayed in the upper column with the extracted data displayed in the lower column. Then, the metadata, which are determined to be closer to the client's requirement between the metadata displayed on the reference data display part and the metadata displayed on the comparison data display part, are made to be reference data, and next data are displayed on the comparison data display part from an extracted data group.
