- 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
- Verity Search 97 software will index and search e-mail, attachments, folders and documents on local and network disk drives. The Internet may be searched via the same front end and changes to particular documents or pages may be monitored. Documents may be viewed in their native formats including ASCII, HTML, PDF and popular word processors, with highlighted search terms. Agents may be launched into the Internet to retrieve information according to a user-specified profile. The software can index about 700 MB an hour. Describes the search technology which includes fuzzy logic and natural language. The Web version of Personal Search 97 works with Netscape Navigator or Microsoft Internet Explorer, while the Exchange version will work regardless of any attachment to an Exchange server. Search 97 Personal improves online time and access time and allows searches to be refined offline

- 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
- The traditional measures of online searching proficiency (recall and precision) are less appropriate when applied to the searching of full text databases. The pilot study investigated and evaluated 5 measures of overall success in searching a full text data bank. Data was drawn from INQUIRER searches conducted by medical students at North Carolina Univ. at Chapel Hill. INQUIRER ia an online database of facts and concepts in microbiology. The 5 measures were: success/failure; precision; search term overlap; number of search cycles; and time per search. Concludes that the last 4 measures look promising for the evaluation of fact data bases such as ENQUIRER

- 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
- OSIRIS und ELIB sind von der Deutschen Forschungsgemeinschaft (DFG) und dem Niedersächsischen Ministerium für Wissenschaft und Kultur (MWK) geförderte Projekte an der Universität Osnabrück. Sie beschäftigen sich mit intuitiv-natürlichsprachlichen Retrievalsystemen und mit Fragen der Indexierung großer Volltexdatenbanken in dieser Technik. Die Entwicklungen haben dazu geführt, daß an sich aufwendige und komplexe Verfahren der syntaktisch-semantischen Analyse und Bewertung von textuellen Phrasen in relationale Datenbanken für Massendaten eingebettet werden konnten und nun im Produktionsbetrieb eingesetzt werden können

- Abstract
- Recently, a detailed evaluation of a large, operational full-text document retrieval system was reported in the literature. Values of precision and recall were estimated usind traditional statistical sampling methods and blind evaluation procedures. The results of this evaluation demonstrated that the system tested was retrieving less then 20% of the relevant documents when the searchers believed it was retrieving over 75% of the relevant documents. This evaluation is described including some data not reported in the original article. Also discussed are the implications which this study has for how the subjects of documents should be represented, as well as the importance of rigorous retrieval evaluations for the furtherhance of information retrieval research

- 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
