Title

End-users, mediated searches, and front-end assistance programs on dialig : a comparison of learning, performance, and satisfaction

Source

Journal of the American Society for Information Science. 41(1990) no.1, S.27-42

Year

Abstract

We trained 40 doctoral students to search INSPEC or ERIC on DIALOG using either the SCI-MATE menu or native commands. Each student then performed a free search on his or her chosen research topic. In comparison with 20 control subjects - doctoral students for whom a free search was performed by a skilled librarian - the experimental subjects were no less satisfied with their retrievals, which were smaller but higher in precision than the retrievals produced by the intermediaries. End-users retrieved as many relevant references as the intermediaries. Use of the menu interface did not affect quality of retrieval or user satisfaction, although subjects instructed to use native commands required less training time, and interacted more with the databases than subjects trained on the SCI-MATE menu.
