Retrieval needs evaluation device, retrieval needs evaluation system and retrieval needs evaluation method

摘要

To provide a retrieval need evaluation device and a retrieval need evaluation method that can develop a product matching retrieval intention and produce a Web page by indicating information allowing for estimating the retrieval intention.SOLUTION: In an evaluation system, a retrieval need evaluation device acquires a plurality of document data, converts the content or structure of the plurality of document data into characteristic vector data, and classifies the plurality of document data into a plurality of subsets by subjecting the converted characteristic vector data to processing according to the algorithm for predefined statistical classification. The retrieval need evaluation device outputs an analysis result of property of retrieval need on the basis of the relationship between the plurality of subsets.SELECTED DRAWING: Figure 2
