Semantic Integration of Conceptual Schemas

Our goal is to work out an integration process which makes it possible to give a global design schema obtained from several schemas, each of them describing the same reality viewed in different ways, in order to obtain the fullest view. Problems and conflicts arise during the schema integration. They are due to the several ways of representing the knowledge semantic and of structuring knowledge (using a same design model). When the detection and solution of structural problems are model dependent, the detection and solution of semantic problems are not model dependent. To represent the semantic of the words which are used in a schema, we have defined a model of thesaurus drawn from the domain dealing with the meaning of words: linguistics. In this paper, we will show the interest of using this fuzzy thesaurus when design schema are being integrated.
