On the Use of Librarians Selection Routines in Web Search.
Tsinakos, Avgoustos A.; Margaritis, Kostantinos G.
Information retrieval on the World Wide Web has a major obstacle: although data is abundant, it is unlabeled and randomly indexed. This paper discusses the implementation of a consultative Web search engine that minimizes the expertise level that is required from a user to accomplish an advanced search session. The system takes advantage of the meta-knowledge (Selection Routine), used by expert librarian searchers and applies it to a heterogeneous search space such as CD-ROM databases and Web-based environments acting as an intermediary expert system. Topics discussed include: (1) the Selection Routine, including the three basic stages of a typical online search--definition of query structure, selection of search keys, and feedback review; (2) system description, including the Web-based interface, spell checker, consultative core, and retrieval component, as well as examples of the Selection Routine and Metaknowledge rule sets; and (3) implementation issues. Three figures present components of an online search, the decision tree of the Selection Routine, and system description. (AEF)
