Thesauri and ontologies in digital libraries: 2. design, evaluation, and development

This tutorial is intended for people who have a basic familiarity with the function and structure of thesauri and ontologies. It will introduce criteria for the design and evaluation of thesauri and ontologies and then deal with methods and tools for their development: Locating sources; collecting concepts, terms. and relationships to reuse existing knowledge; developing and refining thesaurus/ontology structure; software and database structure for the development and maintenance of thesauri and ontologies; collaborative development of thesauri and ontologies; developing crosswalks / mappings between thesauri/ontologies. In summing up, the tutorial will address the question of the amount of resources needed to develop and maintain a thesaurus or ontology.
