- Abstract
- Reports the design, building and testing of the Interactive Ranked Output Search Engine (IROSE), which includes as the main features: query reformulation, ranked output match options, field bias options, marking of must, minus, and truncated suppressed terms. Both DOS and Windows versions of IROSE were constructed and laboratory search tests were performed using 3 test collections of records with queries and relevance jedgements in the subject area of cystic fibrosis, library and information and current affairs. Concludes that there is substantial evidence of the quality of this approach to information retrieval and future tests are needed to redefine and improve the optionality and move to semi operational testing

- Abstract
- An automatic query expansion (AQE) facility in anonline catalogue was evaluated in an operational library setting. The OKAPI experimental system had other features including: ranked output 'best match' keyword searching, automatic stemming, spelling normalisation and cross referencing as well as relevance feedback. A combination of transaction log analysis, search replays, questionnaires and interviews was used for data collection. Findings show that contrary to previous results, AQE was beneficial in a substantial number of searches. Use intentions, the effectiveness of the 'best match' search and user interaction were identified as the main factors affecting the take-up of the query expansion facility

- Abstract
- Queries containing negation are widely recognised as presenting problems for both users and systems. In information retrieval systems such problems usually manifest themselves in the use of the NOT operator. Describes an algorithm to transform Boolean queries with negated terms into queries without negation; the transformation process is based on the use of a hierarchical thesaurus. Examines a set of user requests submitted to the Thomas Cooper Library at the University of South Carolina to determine the pattern and frequency of use of negation.
