User-Centered Maintenance of Concept Hierarchies

Abstract

Taxonomies are hierarchical concept representations that have numerous important applications from improved indexing of document collections to faceted browsing and semantic search applications. The maintenance of taxonomies includes the dynamic extension, analysis, and visualization of these representations. Instead of focusing on the construction of taxonomies from scratch, however, the authors describe several successful approaches to the semi-automatic maintenance of taxonomies. These approaches have in common that they incorporate the human expert as a central part of the system.
