    Content
    Enthält u.a. folgende Aussage von J. Aitchison u. S. Dextre Clarke: "We face a paradox. Ostensibly, the need and the opportunity to apply thesauri to information retrieval are greater than ever before. On the other hand, users resist most efforts to persuade them to apply one. The drive for interoperability of systems means we must design our vocabularies for easy integration into downstream applications such as content management systems, indexing/metatagging interfaces, search engines, and portals. Summarizing the search for vocabularies that work more intuitively, we see that there are trends working in opposite directions. In the hugely popular taxonomies an the one hand, relationships between terms are more loosely defined than in thesauri. In the ontologies that will support computer-to-computer communications in AI applications such as the Semantic Web, we see the need for much more precisely defined term relationships."

    Abstract
    In this Internet age, database users soon learn how invaluable search strategies and effective search skills can be in the quest for information. This book suggests ways to obtain these skills while providing a general introduction to searching online environments. Starting with historical background, the author discusses database structure--records, fields, and indexes--and continues exploring basic search concepts, including Boolean logic, controlled vocabulary, proximity searching, and truncation. Subsequent chapters focus on commercial databases in specific subject areas. Other chapters examine information-seeking behaviors, reference interviews, database evaluation, and teaching others about databases. The content is practical, user-friendly, and enhanced by screen shots, exercises, and supplementary materials. Full of helpful advice and insightful commentary, this text is an outstanding reference tool.
