- Abstract
- A study of the number of irrelevant documents retrieved in a co-ordinate indexing system that does not employ eitherr roles or links. These tests were based on one hundred actual inquiries received in the library and therefore an evaluation of recall efficiency is not included. Over half the enquiries produced no noise, but the mean average percentage niose figure was approximately 33 per cent based on a total average retireval figure of eighteen documents per search. Details of the size of the indexed collection, methods of indexing, and an analysis of the reasons for the retrieval of irrelevant documents are discussed, thereby providing information officers who are thinking of installing such a system with some evidence on which to base a decision as to whether or not to utilize these devices

- Abstract
- Over the last 4 years, the Information Interaction Laboratory at Rutgers' School of communication, Information and Library Studies has performed a series of investigations concerned with various aspects of people's interactions with advanced information retrieval (IR) systems. We have benn especially concerned with understanding not just what people do, and why, and with what effect, but also with what they would like to do, and how they attempt to accomplish it, and with what difficulties. These investigations have led to some quite interesting conclusions about the nature and structure of people's interactions with information, about support for cooperative human-computer interaction in query reformulation, and about the value of visualization of search results for supporting various forms of interaction with information. In this discussion, I give an overview of the research program and its projects, present representative results from the projects, and discuss some implications of these results for support of subject searching in information retrieval systems

- Abstract
- Searches conducted as part of the MEDLINE/Full-Text Research Project revealed that the full-text data bases of clinical medical journal articles (CCML (Comprehensive Core Medical Library) from BRS Information Technologies, and MEDIS from Mead Data Central) did not retrieve all the relevant citations. An analysis of the data indicated that 204 relevant citations were retrieved only by MEDLINE. A comparison of the strategies used on the full-text data bases with the text of the articles of these 204 citations revealed that 2 reasons contributed to these failure. The searcher often constructed a restrictive strategy which resulted in the loss of relevant documents; and as in other kinds of retrieval, the problems of natural language caused the loss of relevant documents.

- Abstract
- Compares the results of subject searching in 2 online catalogue systems, one system with authority control, the other without. Transaction logs from Library A (no authority control) were analyzed to identify searching patterns of users; 885 searches were attempted, 351 (39,7%) by subject. 142 (40,6%) of these subject searches were unsuccessful. Identical searches were performed in a comparable library that has authority control, Library B. Terms identified in 'see' references at Library B were searched in Library A. 105 (73,9%) of the searches that appeared to fail would have retrievd at least one, and usually many, records if a link had been provided between the term chosen by the user and the term used by the system

- Abstract
- Reports results of a study, conducted at Rhode Island University Library, to determine whether cataloguing records known to be missing from a library consortium OPAC database could be identified using the database search features. Attempts to create lists of bibliographic records held by other libraries in the consortium using Boolean searching features failed due to search feature limitations. Samples of search logic were created, collections of records based on this logic were assembled manually and then compared with card catalogue of the single library. Results suggest that use of the Boolean OR operator to conduct the broadest possible search could find 56.000 of the library's missing records that were held by other libraries. Use of the Boolean AND operator to conduct the narrowest search found 85.000 missing records. A specific library search made of the records of the most likely consortium library to have overlaid the single library's holdings found that 80.000 of the single library's missing records were held by a specific library
