A Comparative Study of Differences in Judged Relevance of Abstracts Located by Two Information Systems.
Differences in judged relevance of Educational Resources Information Center (ERIC) abstracts identified by two different information systems were investigated. A national semi-private educational service agency which utilizes mechanical searching of the research literature was one information system, while the other was a regional, Federally-funded agency employing manual searching. Twenty clients reported they found substantially more ERIC abstracts identified by a manual method to be relevant to their needs than abstracts located by a mechanical searching system using the same set of ERIC descriptors.
