- Abstract
- Presents results of an experiment in which 8 indexers (4 beginners and 4 experts) were asked to index the same 4 documents with 2 different thesauri. The 3 kind of verbal reports provide complementary data on strategic behaviour. it is of prime importance to consider the indexing task as an ill-defined problem, where the solutionm is partly defined by the indexer

- Abstract
- Indexers differ in their judgement as to which terms reflect adequately the content of a document. Studies of interindexers' consistency identified several factors associated with low consistency, but failed to provide a comprehensive model of this phenomenon. Our research applies theories and methods from cognitive psychology to the study of indexing behavior. From a theoretical standpoint, indexing is considered as a problem solving situation. To access to the cognitive processes of indexers, 3 kinds of verbal reports are used. We will present results of an experiment in which 4 experienced indexers indexed the same documents. It will be shown that the 3 kinds of verbal reports provide complementary data on strategic behavior, and that it is of prime importance to consider the indexing task as an ill-defined problem, where the solution is partly defined by the indexer him(her)self

- Abstract
- Automatic keyword extraction is an important and fundamental technology in an advanced information retrieval systems. Briefly compares several major keyword extraction methods, lists their advantages and disadvantages, and reports recent research progress in Taiwan. Also describes the application of a keyword extraction algorithm in an information retrieval system for relevance feedback. Preliminary analysis shows that the error rate of extracting relevant keywords is 18%, and that the precision rate is over 50%. The main disadvantage of this approach is that the extraction results depend on the retrieval results, which in turn depend on the data held by the database. Apart from collecting more data, this problem can be alleviated by the application of a thesaurus constructed by the same keyword extraction algorithm
