An Interactive Information Retrieval System; Case Studies on the Use of DIALOG to Search the ERIC Document File.
Timbie, Michele; Coombs, Don H.
The first interactive (on-line) computerized use of the ERIC files by the U.S. Office of Education is reported in the form of an evaluation of the DIALOG system conducted at the ERIC Clearinghouse for Educational Media and Technology. Descriptions of the purposes of the study, of the DIALOG system (developed by Lockheed Missiles and Space Co.), and of the procedures involved in conducting a search of the ERIC file using DIALOG are followed by information on the nine people, from various areas of education, who were asked to help evaluate the system. The major portion of the report, consisting of nine case studies, is based on the reactions of these evaluators (gathered in debriefing interviews) to one or more DIALOG searches which they themselves conducted. In addition, 19 evaluations (based on questionnaires from other system users) are presented. These, along with the nine original evaluations, stress the speed and "horizon-widening" effect of the system. A final section examines the variety of uses for the system at the Clearinghouse. The pre-DIALOG questions, the debriefing outline, and records of the evaluators' searches are appended. (SP/MT)
