    Abstract
    This article reports the findings of an experiment using a simulated title pages, author surnames, and title words, one-third of which were selected by each of the 3 authors, to determine the frequency of one-screen displays when used to search for known items in an implied Boolean retrieval system. Searches comprising surname plus one significant title word produced one-screen displays 78% of time; surname plus 2 words 97% of the time; and surname plus 3 words 98,5%. Three quarters of the significant words were nouns

    Abstract
    This experiment searches an online library catalog employing author surnames, plus title words of books in citations of 8 scholarly works whose authors selected the title words used as being recallable. Searches comprising surname together with two recallable title words, or one if only one was available, yielded a single-screen miniature catalog (minicat) 99.0% of the time

    Abstract
    Reports results of a study to compare the efficiency of the computerized searching of LISA Plus and Currents Research in Library and Information Science (CRLIS) with manual searching of the printed version of LISA. The study focused on articles covering the library and information science profession (LIS), published in Asian library and information science periodicals. The first stage was to identify Asian LIS periodicals using the Ulrich's Plus CD-ROM database. Computerized searching involved 2 methods; straightforward creation of sets for every periodical title; and browsing of brief citations of abstracts of all articles identified as being on the library profession published in the 1993 LISA. The manual searching involved browsing section 2.0 profession for all 11 issues of the printed LISA. Examines the reasons why computeroized searches took more time and retrieved less number of items. Suggests measures whereby the efficiency of computerized searches can be increased and concludes that to ensure comprehensive recall of relevant items, a combination of manual and computerized search is indispensible

    Abstract
    Griesdorf and O'Connor attempt to determine the aspects of a retrieved item that provide a questioner with evidence that the item is in fact on the topic searched independent of its relevance. To this end they collect data from 32 participants, 11 from the business community as well as 21 doctoral students at the University of North Texas each of whom were asked to state if they considered material that approaches a topic in each of 14 specific manners as " on topic" or "off topic." Chi-square indicates that the observed values are significantly different from expected values and the chi-square residuals for on topic judgements exceed plus or minus two in eight cases and plus two in five cases. The positive values which indicate a percentage of response greater than that from chance suggest that documents considered topical are only related to the problem at hand, contain terms that were in the query, and describe, explain or expand the topic of the query. The chi-square residuals for off topic judgements exceed plus or minus two in ten cases and plus two in four cases. The positive values suggest that documents considered not topical exhibit a contrasting, contrary, or confounding point of view, or merely spark curiosity. Such material might well be relevant, but is not judged topical. This suggests that topical appropriateness may best be achieved using the Bruza, et alia, left compositional monotonicity approach.

    Abstract
    This technical note describes straightforward techniques for document indexing and retrieval that have been solidly established through extensive testing and are easy to apply. They are useful for many different types of text material, are viable for very large files, and have the advantage that they do not require special skills or training for searching, but are easy for end users. The document and text retrieval methods described here have a sound theoretical basis, are well established by extensive testing, and the ideas involved are now implemented in some commercial retrieval systems. Testing in the last few years has, in particular, shown that the methods presented here work very well with full texts, not only title and abstracts, and with large files of texts containing three quarters of a million documents. These tests, the TREC Tests (see Harman 1993 - 1997; IP&M 1995), have been rigorous comparative evaluations involving many different approaches to information retrieval. These techniques depend an the use of simple terms for indexing both request and document texts; an term weighting exploiting statistical information about term occurrences; an scoring for request-document matching, using these weights, to obtain a ranked search output; and an relevance feedback to modify request weights or term sets in iterative searching. The normal implementation is via an inverted file organisation using a term list with linked document identifiers, plus counting data, and pointers to the actual texts. The user's request can be a word list, phrases, sentences or extended text.

    Abstract
    Proceedings of the 5th TREC-confrerence held in Gaithersburgh, Maryland, Nov 20-22, 1996. Aim of the conference was discussion on retrieval techniques for large test collections. Different research groups used different techniques, such as automated thesauri, term weighting, natural language techniques, relevance feedback and advanced pattern matching, for information retrieval from the same large database. This procedure makes it possible to compare the results. The proceedings include papers, tables of the system results, and brief system descriptions including timing and storage information

    Abstract
    Die deutschen Suchmaschinen, Abacho, Acoon, Fireball und Lycos sowie die Web-Kataloge Web.de und Yahoo! werden einem Qualitätstest nach relativem Recall, Precision und Availability unterzogen. Die Methoden der Retrievaltests werden vorgestellt. Im Durchschnitt werden bei einem Cut-Off-Wert von 25 ein Recall von rund 22%, eine Precision von knapp 19% und eine Verfügbarkeit von 24% erreicht
