The BA Previews Project: The Development and Evaluation of a Mechanised S.D.I. Service for Biologists. Final Report. OSTI Report No. 5140.
Leggate, P.; And Others
During a 2-year period (1970, 1971) SDI (Selective Dissemination of Information) search profiles were written for 353 biologists and other research workers with a need for biological information in academic, industrial, and government research institutions. At the beginning of the experiment a questionnaire and interview survey was made of the information resources then being used by participants, with particular references to their usage of the printed Biological Abstracts (BA). A quantitative description of service performance was provided by the measurement of the following parameters: output sizes, recall ratios, precision ratios, coverage ratios, and novelty ratios. The relevance predictability of the enriched titles which appear on the BA Previews tapes was also studied. The users' reactions to the service were assessed by means of another survey at the end of the experiment. Correlations between quantitative performance measures and the users' assessment of the service, were examined. It was concluded that the results obtained in the project justified a further experiment in which biologists would be asked to make a payment toward the cost of the service, in addition to providing feedback.
