Why is it important?
Controlled vocabularies play an important role in information retrieval. Numerous studies have shown that conceptual searches based on vocabularies are more effective than keyword searches, at least in certain contexts. Consequently, new ways must be found to improve controlled vocabularies.
Perspectives
Do you think that the collective knowledge is useful? Why not use it to update the controlled vocabularies? This paper presents an experimental development in which, first, the suitability of a controlled vocabulary to a text corpus is examined. Then the keywords entered by users to access the text corpus are compared with the descriptors used to index it. And finally, both the query logs and text corpus are processed to obtain a set of candidate terms to update the controlled vocabulary.
