Classification from PRECIS: Some possibilities
Phyllis Allen Richmond · Journal of the American Society for Information Science · 1976
Abstract The PREserved Context Index System (PRECIS) developed for subject indexing for the British National Bibliography is discussed as a basis for various studies relating to classification which could be made from its initial phrases, strings, entries and back‐up structure. Specific possibilities include use of methodologies such as Goffman's “indirect method,” Fox's “characterization” of rules, derivation of empirical hyperbolic distributions, and lognormal distributions. The relationship of existing methods of subject analysis to each other through PRECIS is explored. Brief samples are included.
