- Yahoo! Cataloging the Web. Callery, Anne Cataloging Classification Information Retrieval Information Sources Internet Keywords Online Searching Subject Index Terms World Wide Web The Internet has the potential to be the ultimate information resource, but it needs to be organized in order to be useful. This paper discusses how the subject guide, "Yahoo!" is different from most web search engines, and how best to search for information on Yahoo! The strength in Yahoo! lies in the subject hierarchy. Advantages to searching a hierarchical subject index include the following: a higher relevancy rate of items retrieved; the user doesn't need to know all the synonyms of a search term to bring up a topic; and the serendipitous discovery of related items. As opposed to using standard library classification systems, Yahoo! creates its own classification system. Yahoo! currently receives thousands of submissions each day. Every site added is examined by a human being. The suggested category (that which the submitter selects) is used as a guide. Subject lists are organized on a dedicated server and distributed among the catalogers. The cataloger selects an item from the list and a display is brought up. There are fields for title, URL, contact person, geographic location, descriptive comment, and indicators for the presence of Java and VRML. Users can search for information in Yahoo! in two ways. One is by browsing the subject tree and the other is by keyword search. The Yahoo! search can also be incorporated into browsing. (AEF)
