“…In many aspects, all of the major packages offered very similar facilities. In a review of nine packages, the major text retrieval functions were found to be provided in all the systems tested [17]. The major functional differences considered in these case studies related to the user environment and potential applications.…”

The selection of software can be greatly aided by the application of information science concepts. This is particularly well demonstrated in the choice of a text retrieval system and two case studies illustrating this fact are presented. The case studies provide contrasting user environments for analysis, enabling comparison between a project-based, matrix organisation and the more rigid, line-management structure. The differing requirements for a text retrieval package are investigated with particular emphasis on potential uses of the software within each organisational framework The constraints of the user environment demonstrated to play a major role are existing hardware and software, together with the mechanisms of information flow apparent in each company.Whilst the functional capabilities of the software are taken into consideration, the working environment and the needs of the users are seen to be of greater significance in the final choice of a system, regardless of organisational structure

“…Secondly there is information retrieval, usually from text-oriented databases, which involves the use of natural rather than artificial language and does not rely on an exact match to achieve useful results via powerful indexing facilities. 12 For certain applications, such as in the commercial and marketing area, there is often a need for a combination of both approaches. Thus both ad hoc and standard searches may be required.…”

“…Many such text retrieval systems are now available [2,24,35]. However, while inverted files provide a very fast response, both the creation and the maintenance of the indexes are highly demanding of storage and processing resources.…”

Efficiency of text scanning in bibliographic databases using microprocessor-based, multiprocessor networks

Boyer-Moore pattern matching algorithm was used to search 35 natural language quenes against a file of 1000 titles and abstracts taken from the Library and Information Science Abstracts database. A model of searching using a singly-linked chain containing up to 11 transputers was carried out: the maximum speed-up obtained with this size of network was 10.4 with a processor utilization of 0.95, both figures being close to the ideal of 11.0 and 1.0. Expenments with a nearest neighbour searching algorithm for serial document files demonstrate the need to keep the processors fully occupied with computational work if a high degree of speed-up is to be obtained.
