A hybrid approach to generating and utilizing faceted vocabulary for knowledge discovery on the Web

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. Our study investigates a hybrid approach that leverage 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. In our study, we explored integration of text- and classification-based methods that combines the strengths of vastly different approaches to information discovery by constructing and utilizing a flexible information organization scheme from an existing classification structure. We also examined integration of searching and browsing in our concept search application.
