Methodologie et structuration d'un outil de decouverte de connaissances base sur la litterture biomedicale : une application basee sur le MeSH

摘要

The information available in bibliographic databases is dated and validated by a long process and becomes not very innovative. Usually bibliographic databases are consultated in a boolean way. The result of a request represente is a set of known which do not bring any additional novelty.In 1985 Don Swanson proposed an original method to draw out innovative information from bibliographic databases. His reasoning is based on systematic use of the biomedical literature to draw the latent connections between different well established knowledges. He demonstrated unsuspected potential of bibliographic databases in knowledge discovery. The value of his work did not lie in the nature of the available information but consisted in the methodology he used. This general methodology was mainly applied on validated and structured information that is bibliographic information. We propose to test the robustness of Swanson's theory by setting out the methods inspired by this theory. These methods led to the same conclusions as Don Swanson's ones. Then we explain how we developed a knowledge discovery system based on the literature available from public biomedical information sources.
