Title

Classification schemes revisited : applications to Web indexing and searching

Abstract

Basic skills of classification and subject indexing have been little taught in British library schools since automation was introduced into libraries. However, development of the Internet as a major medium of publication has stretched the capability of search engines to cope with retrieval. Consequently, there has been interest in applying existing systems of knowledge organization to electronic resources. Unfortunately, the classification systems have been adopted without a full understanding of modern classification principles. Analytico-synthetic schemes have been used crudely, as in the case of the Universal Decimal Classification (UDC). The fully faceted Bliss Bibliographical Classification, 2nd edition (BC2) with its potential as a tool for electronic resource retrieval is virtually unknown outside academic libraries

Content

A short discussion of using classification systems to organize the web, one of many such. The authors are both involved with BC2 and naturally think it is the best system for organizing information online. They list reasons why faceted classifications are best (e.g. no theoretical limits to specificity or exhaustivity; easier to handle complex subjects; flexible enough to accommodate different user needs) and take a brief look at how BC2 works. They conclude with a discussion of how and why it should be applied to online resources, and a plea for recognition of the importance of classification and subject analysis skills, even when full-text searching is available and databases respond instantly.
