摘要

PROBLEM TO BE SOLVED: To construct a data base for providing a service without being restricted by the structure/form of a document for the perusal of an information provider by performing normalization processing of an attribute structure as of contents attribute information and performing normalization of a character expression form and normalization processing of numerical expression. ;SOLUTION: An automatic information collecting part 101 of an automatic information collecting and classifying device 100 patrols a Web site 120 of an information provider on a network 110, collects document files and extracts information. An attribute extraction part 102 normalizes a character code and then extracts only the contents attribute information as of the collected and extracted documents. An attribute normalization part 103 refers to a normalization rule 106 and normalizes the contents attribute information provided with the structure/form coincidently with a perusal document extracted by the attribute extraction part 102 to the form suited to a retrieval service or the like.
