    Abstract
    Defines the basic functions of surrogate files in information retrieval. Exemplifies the categories enunciated in the general theory of classification developed in India. Defines the principles for structuring the concepts. Formulates set of general postulates pertaining to the structure of compound subjects.

    Abstract
    After establishing the terminology, shows how the choice of the name of the subject of a document and the rendering of the name in the heading of the specific subject entry can be got by facet analysis based on postulates and principles. After showing that subject headings constitute an artificial language, points out that using facet analysis for subject heading does not amount to using class number. Marks out the area for an objective statistical survey of sought heading for subject entry. Calls on Council for Library Resources Incorporated to provide for this project

    Abstract
    Both classification systems and thesauri have their specific strengths and weaknesses. Through properly combining both approaches one can eliminate the latter and largely preserve the strenghts. 'Classauri' which originate in this well-known way are most effective if they are constructed and applied during computer-aided indexing. A special variety of classaurus is described which is characterized by the employment of simple bur highly effective conceptual and technical devices and by the renunciation of attempts to generate the wording of index entries algorithmically

    Abstract
    There are many advantages for Digital Libraries in indexing with classifications or thesauri, but some current disincentive in the lack of flexible retrieval tools that deal with compound descriptors. This paper discusses a matching function for compound descriptors, or multi-concept subject headings, that does not rely an exact matching but incorporates term expansion via thesaurus semantic relationships to produce ranked results that take account of missing and partially matching terms. The matching function is based an a measure of semantic closeness between terms, which has the potential to help with recall problems. The work reported is part of the ongoing FACET project in collaboration with the National Museum of Science and Industry and its collections database. The architecture of the prototype system and its Interface are outlined. The matching problem for compound descriptors is reviewed and the FACET implementation described. Results are discussed from scenarios using the faceted Getty Art and Architecture Thesaurus. We argue that automatic traversal of thesaurus relationships can augment the user's browsing possibilities. The techniques can be applied both to unstructured multi-concept subject headings and potentially to more syntactically structured strings. The notion of a focus term is used by the matching function to model AAT modified descriptors (noun phrases). The relevance of the approach to precoordinated indexing and matching faceted strings is discussed.
