Title

How do you describe a symbol? : the problem involved in retrieving symbols from a database

Abstract

Identifies the need for a suitable information system for retrieving images from a database. Various search objectives are described which cannot be met by current retrieval methods. A number of approaches to the problem are discussed and the advantages of a flexible classification system are highlighted. By analysing the formal attributes of symbols, a classification structure is derived which starts with a division into graphic, semantic and bibliographic dimensions. 2 experimental tasks are used to examine user's perceptions of the features of symbols. These results can be used to fill in the detailed descriptions in the classification system
