    Abstract
    In the preparation of a book on how to do a literature search, many inconsistencies were found in the assignment of subject terms. The Library of Congress Subject Headings is cited for not bringing computer languages into a consistent pattern. BASIC and FORTRAN are treated differently in their see also references and are without references to the words "computers" or "computer." Also index terms for the literature search on the "search for extraterrestrial life" showed inconsistent patterns in indexing. Catalogers and indexers need to review the work they are currently publishing and try to decide how to bring some standardization to the construction of subject terms. There is a need to provide a single thesaurus for all English index terms.

    The National Central Library in Florence, Italy, has commissioned a feasibility study for the renewal of the Soggettario [Subject headings for Italian libraries]. [It is indispensable for the theoretical development to take place within the international debate and to approach the topic of a new Soggettario with reference to the FRBR.}. The subject is analysed as a relation between the entities in the third group: concept, object, event, place and the entity work. The model identifies the logical entities, attributes and relationships which run between the entities. The article returns to and amplifies the user tasks of FRBR which involve a subject: (1) Find the works on a given subject; (2) Find the works in which a concept is significantly treated; (3) Select a work by its main subject only; (4) Lead to a search for works on related subjects; (5) Lead to a search for works in which related or connected subjects are handled.

    Abstract
    A commonly used technique for improving search engine performance is result caching. In result caching, precomputed results (e.g., URLs and snippets of best matching pages) of certain queries are stored in a fast-access storage. The future occurrences of a query whose results are already stored in the cache can be directly served by the result cache, eliminating the need to process the query using costly computing resources. Although other performance metrics are possible, the main performance metric for evaluating the success of a result cache is hit rate. In this work, we present a machine learning approach to improve the hit rate of a result cache by facilitating a large number of features extracted from search engine query logs. We then apply the proposed machine learning approach to static, dynamic, and static-dynamic caching. Compared to the previous methods in the literature, the proposed approach improves the hit rate of the result cache up to 0.66%, which corresponds to 9.60% of the potential room for improvement.

    Abstract
    The Association for Manitoba Archives has created a database where members can deposit archival descriptions to provide a central search for users. Library of Congress Subject Headings (LCSH) were chosen as the controlled subject vocabulary to use in the descriptions, but changes were made to LCSH to better describe material about or by Indigenous peoples. Examples include: the word "Indian"; geographic place embedded in terms such as "Indians of North America"; changes related to Manitoba peoples specifically; and miscellaneous changes not part of a larger pattern. New terms were also added.

    Abstract
    Reports results of a study to explore the possibilities of extending the use of structured abstracts (which use subheadings such as background, aims, participants method, results, conclusions) of the type often found in biomedical periodicals; to test whether or not such structured abstracts are more easily searched, comprehended and recalled than abstracts set in the traditional manner; and to examine readers' preferences for different typographic settings for structured abstracts. Results indicated: that it is possible to produce structured abstracts for periodical articles in the social sciences; and that such abstracts may be easier to read, search and recall than abstracts presented in the traditional manner. Suggests that abstracts use 6 subheadings (background, aims, method, results, conclusions, and, optionally, comment) and recommends that these subheadings are conveyed in bold capital letters and, ideally, set apart from the main text by printer's rules

    Abstract
    The introduction of computerized post-coordination has solved many of the problems of pre-coordinated subject access. However, the adoption of computerized post-coordination results in the loss of some pre-coordination benefits. Specifically, the effect of hiding terms within the context of others is lost in post-coodination which give lead status to every document term. This results in spurious matches of terms out of context. Library patrons and Internet searchers are increasingly dissatisfied with subject access performance, in part because of unmanageably large retrieval sets. The need to enhance precision and limit the size of retrieval sets motivates this work which proposes partial coordination, an approach which incorporates the advantages of computer search with the ability of pre-coordination to limit spurious partial matches and thereby enhance precision

    Abstract
    Library of Congress Subjecl Headings retrieved as the results of a search in an online catalog are likely to be filed in straight alphabetical, word-by-word order, ignoring the semantic structures of these headings and scattering headings of a similar type. This practice makes LC headings unnecessarily difficult to use and negates much of their indexing power. Enthusiasm for filing simplicity and postcoordinate indexing are likely contributing factors to this phenomenon. Since the report Headings for Tomorrow (1992) first raised this issue, filing practices favoring postcoordination over precoordination appear to have become more widespread and more entrenched
