%0 Journal Article %T A method for the evaluation of the peculiar lexicon significance %A Flora Amato %A Antonino Mazzeo %A Sergio Scippacercola %J Electronic Journal of Applied Statistical Analysis : Decision Support Systems and Services Evaluation %D 2011 %I Universit¨¤ del Salento %X In this work, a methodology for semi-automatic derivation of knowledge from document collections is proposed. In order to extract relevant information from documents, a process integrating both statistical and lexical approaches is applied. We propose a strategy for the semantic evaluation of the index terms extracted in order to ensure a good correspondence between the information searched for and the information retrieved. Therefore, we propose a system for the peculiar lexicon extraction and assessment. The system can be used for defining an ontological model to be used in the semantic processing of a corpus of documents belonging to a specialist domain. %K Semantic Processing %K Peculiar Lexicon Extraction %U http://siba-ese.unisalento.it/index.php/ejasa_dss/article/view/6455
