Abstract

Most moving image collections have existed for less than a century, and as we enter the new millennium we observe that the organisation of these collections is still characterized by ad hoc practices. An important stream of research in this area focuses on high-level access to images using methods from library and information science, and using text to create information useful for retrieval. It has been established that common names for objects seen in the image are the key to retrieval in such collections. On a day-to-day basis, those responsible for collection management build indexing vocabularies, creating terms as necessary, and often structuring them loosely into a thesaurus. Discussions with moving image collection librarians have led us to believe that there may be an optimal number of common names a thesaurus for managing general collections of moving images should contain, and that the terms may even be the same from one thesaurus to the next. In this paper, we describe the methodology adopted for studying this question, and report preliminary results
