Citation indexing, which matches linked articles through links with authors rather than through subject keyword matching, is particularly relevant to educational technology, a widely-spread subject with a special user group of varying interests, difficult to cover in one retrieval service, and whose terminology is often ambiguous. By including links from lists of references, very large databases are created, some of whose links may be misleading. Qualified citation indexing seeks to refine the output by including terms that are mutually exclusive and unambiguous to describe the context of the reference. The Scottish Education Department Qualified Citation Indexing Project is setting up a citation database with linked references from citing to cited work, the links qualified by using a list of relational or descriptive terms compiled from previous studies and the suggestions of users. Retrieval will be tested and modifications will be built in from feedback thus acquired and a prototype index will be presented. A major part of the work will be the identification of key authors and key papers and estimates will be made of both computing and indexing costs. (Author/RAA)
