Between traditional classification and coordinate indexing

摘要

An ordering system for a global information network is necessary in order to enable the user to retrieve the particular information he is looking for. Classification has been one of the methods of ordering. The principle of traditional classification has been based on the idea of partitioning the universe of knowledge in mutually exclusive classes, i.e. subjects. A particular topic is defined by narrower classification within a class following the principle of ‘genusspecies’ relationship. Ranganathan's system of faceted classification has only replaced the classification of terms into subjects and sub-subjects by classification of terms into five ambiguous categories. Taube's system of coordinate indexing gives full freedom to the user to combine any number of terms of his choice. To be effective for social sciences such a system has to overcome some difficult problems of semantics. The system MANIS described here maintains the traditional classification and yet allows the user to combine terms of his choice, where the choice is restricted to the terms belonging to the system of traditional classification.
