- Abstract
- A bilingual Welsh-English full text database is planned for Inspection Reports of Her Majesty's Inspectors of Schools for Wales. Special requirements for free text retrieval in the Welsh language are identified, and practical solutions are proposed for problems arising from the use of standard text database products, some of which may also apply to other lesser-used languages

- Abstract
- Discusses the 2 major query evaluation strategies used in large text retrieval systems and analyzes the performance of these strategies. Discusses several optimization techniques that can be used to reduce evaluation costs and present simulation results to compare the performance of these optimization techniques when evaluating natural language queries with a collection of full text legal materials

- Abstract
- Presents research in which 4 term weigthing schemes were used to detect information rich passages in texts and the results compared. Demonstrates that word categories and frequency derived weights have a close correlation but that weighting according to the first mention theory or the cue method shows no correlation with frequency based weights

- Abstract
- Reports on a comparison of 2 natural language interfaces to full text legal databases: WIN for access to WESTLAW databases and FREESTYLE for access to the LEXIS database. 30 legal issues in natural langugae queries were presented to identical libraries in both systems. The top 20 ranked documents from each search were analyzed and reviewed for relevance to the legal issue

- Footnote
- Novice end users were given 2 hours of training in searching a full-text magazine database (Magazine ASAP(TM)) on DIALOG. Subjects searched during 3 to 4 sessions in the presence of a trained monitor who prompted them to think aloud throughout the sessions. qualitative analysis of the transcripts and transaction logs yielded empirical information on user variables (purpose, motivation, satisfaction), uses of the database, move types, and every question users asked during the searches. The spontaneous, naturalistic questions were categorized according to affective, cognitive, and sensorimotor speech acts. Results show that most of the searches were performed for the self and were work related. The most common use of the database was to retrieve full-text articles online and to download and print them out rather than read them on screen. The majority of searches were judged satisfactory. Innovative uses included browsing for background information and obtaining contextualized sentences for language teaching. Searchers made twice as many moves to limit sets as moves to expand sets. Affective questions outnumbered cognitive and sensorimotor questions by two to one. This preponderance of affective micro-information needs during searching might be addressed by new system functions

- 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
