Construction of navigation map to retrieve semantically information from medical resources

摘要

Semantic information retrieval has been a topic of great interest in recent years. Its purpose is to improve the effectiveness of information retrieval methods by exploiting the semantic information in documents and queries. Many approaches have been proposed to retrieval semantically the information. In this article, we propose a new approach based on domain ontology and natural language processing (NLP) techniques. In our approach, we represent resources and queries by a list of concepts. This allows us at the second level to create a semantic map of concepts and terms extracted from resources. Through this map, we propose to the users a proximity champ allowing them to find, in the one time, pertinent resources according to their query and in the second time to discover a new knowledge by navigating in semantic proximity relations.
