Abstract

Early research at the end of the 1950s on computerized indexing used statistical methods based on e.g. frequency, probability, clustering, and relevance. In the 1960s interest began to focus on linguistic analysis and natural language processing e.g. morphological, morphosyntactical, syntactical and semantic analysis. Since the 1980s computerized indexing research has widened to include images, graphics and sound. Examples are given of notable systems developed within each line of approach
