BNDI:A Bayesian Network for biomedial Documents Indexing with MeSH thesaurus

—We propose a new approach denoted BNDI (Bayesian Network for Document Indexing) for indexing biomedical documents with controlled biomedical vocabulary based on a Bayesian Network. BNDI uses the probability inference to extract descriptors from the document. The main contribution of our approach is that it takes into account the structure of biomedical terminologies specially The Medical Subject Heading (MeSH) thesaurus. We experimented our approach on a subset of the OSHUMED collection.
