The Use of ERIC Tapes in Scandinavia, Searching With Thesaurus Terms in Natural Language.
Tell, Bjorn V.; And Others
Since February 1971 the Royal Institute of Technology, Stockholm, has been running the ERIC data base mainly for SDI purposes. The implementation of the data base into the generalized search system, ABACUS, is described. One hundred and fifty-eight users received SDI service at present, 99 from governmental and educational institutions, 23 from industry, and 36 from abroad. Retrospective searches have also been made. Two methods of matching users to documents have been employed - the controlled vocabulary of the Thesaurus of ERIC Descriptors, and the free text words of titles. Some users' assessments of the relevance of the output have been gathered, and examples are given of query formulation into profiles and the resulting printout of references. A number of the profiles for the ERIC data base have also been run on data bases such as ISI, INSPEC and COMPENDEX. The practice of writing profiles which contain term types which are appropriate to only one of several data bases, against which they are searched, is discussed. A frequency list of words in the titles has been compiled in order to use a weighting procedure for sorting the printout. A training program for acquainting the user with this new service is needed.
