Classification Research Group (CRG)

Classification Research Group is a group of working librarians and others interested in classification research in London. When Ranganathan’s ideas of faceted classification began to make an impression in the western world, the Royal Society’s Scientific Information Conference was held in London in 1948, where classification, as a method of subject organization, was discussed as one of the themes. Dissatisfied by the prevailing methods of subject organization, a committee with J.D. Bernal as Secretary was set up to examine the existing systems and suggest possible improvements. No progress was however, made until 1951, when B.C. Vickery was invited to form a group to take over the work of the committee. This heralded the formation of CRG in 1952. The group consists of people who are keenly interested in classification research. A perusal of the reports (“Bulletins”) produced by the CRG indicates that the Group has been actively involved in the creation of several classification schemes for such organizations. The theoretical work of the Group has involved the study of facet analysis, relational operators and the theory of Integrative Levels.” The efforts of the group are directed in two directions: classification and data mining. The classification effort focuses on both methodological research and particularly novel, non-standard applications. The work in classification has significant overlap with other areas, including machine learning and pattern recognition, so that the publications appear in a wide literature. The data mining effort has become focussed primarily on the emergent areas of pattern discovery and detection and streaming data analysis.CRG

CRG made a major contribution towards a new general classification scheme, which was expected to have quite different problems than the special schemes. Each specific subject, in addition to a few core subjects, has some fringe subjects also, which can be treated without any due seriousness in a special scheme where they are supposed to be less important to the subject experts than the core subjects. In a general scheme all subjects have equal weight-age and should be treated accordingly. It was thought that CRG should now turn its attention to the more difficult matter of a new general scheme.
