Construction of Knowledge Base for Automatic Indexing and Classification Based on Chinese Library Classification

摘要

Class number, descriptor and keyword are three kinds of subject concept identifiers, among which there exist some concept ual mapping relationships, i.e. compatibility. According to this principle, we construct a CLC Knowledge Base on the basis of Chinese Library Classification for automatic indexing and classification. We compare it with the CLC system to illuminate its obvious advantages over automatic information processing and concept searching. We then introduce some key technologies in the process of construction at length and describe in brief their application to automatic indexing, automatic classification and concept searching.
