The purpose of this study is to develop a faceted classification scheme linked with a thesaurus(FCT) to more effectively organize documents according to subject, by transforming the current Korean Decimal Classification system(KDC) into a faceted classification scheme and linking it with Korea’s National Library Subject Headings. This combination should represent complex subjects more clearly, allow users to change citation order, and facilitate the addition of new subjects to the KDC scheme. Furthermore, by linking a thesaurus to the classification scheme, it is possible to share facets and expand the conceptual level of headings through the thesaurus descriptors.

In this paper we propose a formal data model of an object-based thesaurus system supporting multi-dimensional facets. According to facets reflecting on respective user perspectives, it supports systematic construction, browsing, navigating and referencing of thesauri. Unlike other faceted thesaurus systems, it systematically manages its complexity by appropriately ing sophisticated conceptual structure through visualized browsing and navigation as well as construction. The browsing and navigation is performed by dynamically generating multi-dimensional virtual thesaurus hierarchies called "faceted thesaurus hierarchies." The hierarchies are automatically constructed by combining facets, each representing a dimension of view. Such automatic construction may make it possible the flexible extension of thesauri for they can be easily upgraded by pure insertion or deletion of facets. With a well defined set of self-referential queries, the thesauri can also be effectively referenced from multiple view points since they are structured by appropriately interpreting the semantics of instances based on facets. In this paper, we first formalize the underlying model and then implement its prototype to demonstrate its feasibility.

Applying one specific thesaurus might cause several problems because each thesaurus has its own characteristics inherited from its construction process. Therefore, integration of thesauri can be an appropriate approach to overcome the difficulties. This current research selected physics as a domain and two thesauri in the domain: PACS and PIRA. By integrating these two heterogeneous thesauri, this research could construct a conceptual structure that covers the whole concepts related to physics. By constructing the conceptual structure with the use of facet analysis from integrated thesaurus, it provides knowledge base with hierarchical structure and clear relationships between concepts. It can be an alternate approach to effective and efficient information retrieval and knowledge discovery.
