Generation and application of faceted vocabulary for knowledge discovery on the Web: an exploratory study

We explored generation and application of faceted vocabulary as a potential mechanism to enhance knowledge discovery on the Web. Generation of faceted vocabulary involved examination of concept pairs extracted from an existing hierarchical classification structure, while application of faceted vocabulary involved both user interface design as well as fusion of retrieval and classification approaches. This paper describes our approach to leveraging existing classification hierarchy to construct and utilize a flexible classification scheme, where users can engage in knowledge discovery process via search and traversal of dynamic concept relationships.
