This introductory workshop is intended for anyone concerned with subject access to digital libraries. It provides a bridge by presenting methods of subject access as treated in an information studies program for those coming to digital libraries from other fields. It will elucidate through examples the conceptual and vocabulary problems users face when searching digital libraries. It will then show how a well-structured thesaurus can be used as the knowledge base for an interface that can
more &raquo; ... users with search topic clarification (for example through browsing well-structured hierarchies and guided facet analysis) and with finding good search terms (through query term mapping and query term expansion -synonyms and hierarchic inclusion). It will touch on cross-database and cross-language searching as natural extensions of these functions. The workshop will cover the thesaurus structure needed to support these functions: Concept-term relationships for vocabulary control and synonym expansion, conceptual structure (semantic analysis, facets, and hierarchy) for topic clarification and hierarchic query term expansion). It will introduce a few sample thesauri to illustrate these principles. Lastly the workshop will give a checklist for evaluating thesauri. Course objectives Participants should appreciate the complexity of subject access and understand the problems that a thesaurus can help solve. Participants should understand the principles of thesaurus structure. Participants should be able to apply thesaurus structure to solving subject access problems. Participate should be able to identify and evaluate thesauri suitable for a specific situation defined by a user community an by the collection of a digital library.
