    Abstract
    Describes SIFT (Search in Free Text) an information retrieval system originally developed for administering governmental documents in Norway but which is now being applied alsewhere. SIFT handles structured information well. A library system, SIFT-BIBL, is now available. SIFT's retrieval engine and search facilities are powerful. Its user interface is limited but being imporved. An application programmer interface has been released which will allow programmers to develop their own interface. A Windows-based- client-server version is now being beta tested

    Abstract
    Der Artikel stellt Ergebnisse einer Studie zur vergleichenden Bewertung von Verfahren der nachfrageorientierten Inhaltserschließung im Volltextarchiv der Stuttgarter Zeitung vor. Im ersten Teil der Arbeit wird empirisch untersucht, ob in der digitalen Pressedokumentation auf eine intellektuelle Indexierung von Artikeln verzichtet werden kann, wenn ausschließlich im Volltext recherchiert wird. Im zweiten Teil der Arbeit werden Möglichkeiten und Grenzen einer innovativen Inhaltserschließung von Volltexten in der Textdokumentation der Stuttgarter Zeitung mittels Digitaler Textdossiers diskutiert

    Abstract
    State of the art review of the development of full text databases, encompassing: types of commercially available full text databases; online systems for full text databases; CD-ROM databases for full text databases; full text databases on magnetic discs or tapes; creation of full text databases; searching and display requirements for full text searching and software. Concludes that bibliographic information services without full text support solve only half of the retrieval problems

    Abstract
    Die bibliothekarische Informationserschließung war unist bislang durch den OPAC geprägt, der im wesentlichen die Monographien und Zeitschriften einer Bibliothek erschließt. Es werden 2 neue Bereiche skizziert, die in Zukunft ebenfalls Teil der bibliothekarischen Informationserschließung sein können und werden: die Erschließung unselbständiger Literatur und der Einsatz automatisierter 'reference and information services'. Im ersten Fall ist die Entwicklung bereits weit vorangeschritten, Verbundsysteme und Library Suppliers bieten bereits Inhaltsdaten von Zeitschriften als Fremdleistung an. Im zweiten Fall ist die Entwicklung, vor allem im angloamerikanischen Raum, noch - trotz zahlreicher Projekte - in den Anfängen. Der Einsatz wissensbasierter Systeme in diesem Bereich macht die Aufgaben hier besonders komplex, biete zugleich aber hanz neue Lösungsmöglichkeiten an, wie am Beispiel einiger amerikanischer Projekte dokumentiert wird. Wesentlich ist, daß Informationserschließungssysteme, wie sie ansatzweise im Internet bereits eingesetzt werden, den gesamten bereich elektronischer wie herkömmlicher Information umfassen, um einen allgemeinen und umfassenden Einstieg für den Informationssuchenden zu bieten

    Abstract
    Describes a research goal set by many offices within the US Department of Energy. Reviews efficient full text searching techniques being developed to better understand and meet this goal. Classical computer human interaction (CHI) approaches provided by commercial information retrieval engines fail to contextualize information in ways that facilitates timely decision making. Discusses the uses of advanced CHI techniques in combination with deductive database technology to augment the weaknesses found in the presentation capabilities of information retrieval engines. Presents various techniques employed in a WWW based prototype system currently under development

    Abstract
    At Rotterdam Ports Authority in the Netherlands the Habour information database includes a press cuttings service and various online databases. To enable research staff to have direct access to information the POINT (Point Information Net) was begun in 1993. Using Verity software POINT provides simultaneously full text searching on a range of databases. The software uses current Web indexing technqiues to overcome the problems of excessive recall and low precision. A key element is the system's ability to recognise word combinations

    Abstract
    At Rotterdam Port Authority an information database has been created with approx. 100.000 full text documents online. Topic software has been used to identify word groups and refine search strategies to optimize precision and recall. The software guides users from selected terms to other relevant word combinations. Although the system would benefit from further refinement, users are generally satisfied. The database includes a number of foreign language documents but lacks a thesaurus of foreign terms

    Abstract
    Dow Jones Interactive Publishing has developed a sophisticated automatic knowledge indexing system that will allow searchers of the Dow Jones News / Retrieval service to get highly targeted results from a search in the service's Publications Library. Instead of relying on a thesaurus of company names, the new system uses a combination of that basic algorithm plus unique rules based on the editorial styles of individual publications in the Library. Dow Jones have also announced its acceptance of the definitions of 'selected full text' and 'full text' from Bibliodata's Fulltext Sources Online directory

    Abstract
    Examines how techniques in the field of natural language processing can be applied to the analysis of text in information retrieval. State of the art text searching programs cannot distinguish, for example, between occurrences of the sickness, AIDS and aids as tool or between library school and school nor equate such terms as online or on-line which are variants of the same form. To make these distinction, systems must incorporate knowledge about the meaning of words in context. Research in natural language processing has concentrated on the automatic 'understanding' of language; how to analyze the grammatical structure and meaning of text. Although many asoects of this research remain experimental, describes how these techniques to recognize spelling variants, names, acronyms, and abbreviations

    Abstract
    Describes a typical traditional 1989 free text system and discusses developments in data storage, in search strategy and in the storage and retrieval of real time data. Outlines the following areas in which free text systems are likely to develop: standards; integration; dynamic data exchange; improved user interfaces; and better retrieval methods

    Abstract
    Full text management which applied to document management tends to be centred on text storage and retrieval. Recent developments are concerned with integration with relational database management system products to deliver document management services offering both the flexibility of text retrieval and the ability to support process based funnctions. There has been a move towards client server architectures, more user friendly user interfaces and more flexible and easier to understand retrieval. Advocates caution in choosing tasks for full text methods. Identifies document management functions for which the combined use of database management systems or special purpose tools should be considered

    Abstract
    In this article, the fourth in a series on microcomputer software for information storage and retrieval, test results of six indexing and full-text retrieval programs are presented and various properties and qualities of these programs are discussed. The common faeture of programs in these categories is that they are primarily meant to retrieve words (or combination of them) in large text files. To do this they either simply index existing text files in one or more formats (indexing programs), or they store and index them in their own database format (full-text retrieval programs). The programs reviewed in this issue are the indexing programs Ask-it, Texplore and ZYindex and the full-text retrieval programs KAware, textMaster and WordCruncher. All programs run under MS-DOS. In addition ZYindex has a Windows and a Unix version and TextMaster is also available for for Unix. For each of the six programs almost 100 facts and test results are tabulated. The programs are also discussed individually
