DEVICE, METHOD, AND PROGRAM FOR GATHERING WEB INFORMATION

摘要

PROBLEM TO BE SOLVED: To reconstruct semi-structured or unstructured web information such as an HTML file and a PDF file for integrating necessary web information and facilitating classification and search.

SOLUTION: An attribute and an attribute value of gathered meta-information are compared with a vocabulary set list to determine whether they correspond or not. Then, a web information integration device refers to an attribute characteristic rule to determine whether they correspond or not. The web information integration device assumes the meta-information coincident in the all of determinations as information related to a product and stores the meta-information and the web information. The web information integration device also stores integration information coincident with the vocabulary set list and a rule coincident with the attribute characteristic rule as meta-metainformation. The meta-metainformation is used by a retrieval means for searching optional meaning from the stored web information.
