| Abstract | This report evaluates the engineering information services provided by the University of Calgary since implementation of the COMPENDEX (tape service of Engineering Index, Inc.) service using the IBM TEXT-PAC system. Evaluation was made by a survey of the users of the Current Information Selection (CIS) service, the interaction between the system and the users, system performance on the monthly computer runs, and user satisfaction. Costs of running time for some programs and of providing CIS, along with a pricing policy, are provided. A test of TEXT-PAC as a data base for full text searching capability was conducted, and the limiting factors of the TEXT-PAC system were explored. Because of its large data base and full text processing capability, the COMPENDEX system performance is reasonable. Improvements in relevance and recall can be made by improvements in formulating user profiles. Continuous system evaluation is required, along with user and search-editor training, improved feedback, and provision of word-frequency listings as an aid to correct profile formulation. (AB) |
