Fuzzy knowledge engineering techniques in scientific document classification

The construction of data bases containing information concerning scientific libraries requires cooperation between experts of different scientific domains. These experts are the source of knowledge that help the librarian in the process of characterizing the documents by means of relevant features, relating them using a thesaurus and generating useful and informative classifications of the documents to facilitate its retrieval. In this work, we describe an implementation based on a knowledge acquisition process that uses a knowledge engineering methodology: Our system helps the expert in a domain, to elicitate the concepts that he uses and to characterize the documents of the domain. The system also helps the librarian in the design of the thesaurus and the classifications.
