Facets are used to design a new classification system for Law.
Why a new classification?
– to provide stakeholders in the wide area of Law with a freely available robust indexing tool that lends itself to automation easily and that can serve the following purposes
enable browsing and searching across subject areas of humanities
enable different kinds of display and collection presentation (choice of facets and order of facets, showing or hiding notation, expanding or collapsing the range of facets or facet hierarchy)
be suitable for traditional, digital or hybrid collections (by providing for traditional as well as digital media)
be used on any level of specificity without limitation
be expandable with vocabulary from other systems (e.g. geographical data)
serve as a good basis for thesaurus creation
be easy to map to indexing systems already in use in the collections (Encyclopedia of Law)
be manageable within the portal architecture e.g. have transportable and shareable authority data that can serve as an intelligent cataloguing/classification mapping tool or as a basis for the future automation of indexing .
As Written by Vanda Broughton:
“Facet analysis in a rudimentary form was conceived by S.R. Ranganthan in the 1930s, although it had been preceded by similar analytico-synthetic approaches to subject classification and indexing, notably by Henry Bliss and Paul Otlet in the classification field, and Kaiser in indexing. It was developed post 1950, principally by members of the UK Classification Research Group, as a tool for the organization of document collections in technical, scientific and social scientific fields, where it was highly effective in the storage and retrieval of compound and complex subjects.
Modern facet analytical theory contrasts with earlier views of knowledge as an integral whole (which is broken down into smaller and smaller units) in that it deals with individual terms or concepts which are clustered into categories to create a ‘bottom-up’ map of knowledge. A number of categories have been identified which are widely applicable to the terminologies of a range of subject fields; these categories are generally functional and/or linguistic in nature (e.g. entities, processes, properties, operations, agents). Compound and complex subjects are accommodated by combining individual concepts. Various forms of system syntax (links and rules for ordering and combination between categories) have been proposed to compound the individual concepts, most of which are based on natural language models; the method used in ‘classical’ UK facet theory depends on a formulaic inter-category order (citation order).
Currently, facet analysis is used primarily to create classifications for the physical arrangement of documents (or document surrogates). The completed classification or knowledge structure is built up from individual terms which are analysed into categories and ordered by the application of the system syntax. The resultant structure is logical and predictable, and therefore highly effective in storage and retrieval. The only widely used classification embodying these principles is the second edition of the Bliss Bibliographic Classification, which employs standard categories and citation order. It seems probable that this methodology of facet analysis can be used in a broader and more innovative way to create much deeper and more complex knowledge structures and semantic networks, by extending the range of categories and by exploring variants on combinatorial methods. Although the faceted classification is regarded by many as a structure with specific characteristics, essentially facet analysis is a technique, and different models of the same universe of discourse can be derived to meet different local or subject-specific needs using different categories and variations on the syntax.
Some research is now required into the fuller range of categories and relations that may be encountered across the complete range of disciplines. Work is also required on the problems of interdisciplinarity, and alternative approaches to the structuring of knowledge that do not depend on traditional disciplines as the first point of entry; in this area, classifications of phenomena (as opposed to the more conventional aspect classifications), and the further application of integrative level theory, require some investigation. Additional properties of digital objects, especially non-text, multi-media and images, can also provide data for categorical analysis, and may affect the potential syntax of the system. The formulae developed for the combination of terms and concepts will generate n-dimensional structures that seem appropriate to a hypertext environment. Structures generated from the expanded category base may be particularly useful in handling digital objects.”
