An HTML document 1 (HTM) shown in FIGS.
In L documents A and B), using the fact that the part after the anchor is often an explanation, the link name, explanation, and keyword are extracted, and the two classification information 4 in FIGS. 4 and 5 are extracted. I do. The format of the extracted classification information 4 is shown in FIGS.
As shown in the table, the URL is classified into “URL”, “name”, “description”, “keyword” and “change flag”. Here, the keyword is extracted from the document title, the name of the link, and the description. In this example, it is extracted from the link name and description.

FIG. 6 is a diagram showing classification system definition information, and FIG. 7 is a table showing summarized classification information. In the classification system definition information 6 shown in FIG. 6, it is assumed that keywords which the user is interested in are written. At this time, the extracted classification information 4 is merged in the following two steps. 1. A line of classification information having a keyword that matches a node of the classification system is collected into the node. At this time, a different notation dictionary may be used to determine the match, and in the case of synonyms, the keywords may be regarded as the same keyword (in the example, the product and the product are identified). 2. If the same row is assigned to a node in a parent-child relationship, the one in the parent node is excluded. As a result, the grouped classification information as shown in FIG. 7 is obtained, and the information of interest can be efficiently systematized and obtained.
