Title

Knowledge based classification systems : basic issues, a toy system and further prospects

Source

International classification. 16(1989), S.146-156

Year

1989

Abstract

This article propagates expert systems for classification by (1) explaining the conceptual affinity (especially) between faceted classification schemes and frame representations, using a simple example and a toy system for demonstration purposes, (2) reviewing some approaches to classificational knowledge processing, both from Artificial Intelligence and Classification Research or Information Science, in order to prepare the ground for the development of more comprehensive systems: expert systems for classification
