Software tools processing partially common set of data should share an understanding of what these data mean. Since ontologies have been used to express formally a shared understanding of information, we argue that they can be used to improve integration in Software Engineering Environments (SEE). In this paper we discuss an ontology-based approach to improve tool integration and present ODE, an ontology-based SEE.Eje: Ingeniería de Software y Bases de Datos (ISBD)Red de Universidades con Carreras en Informática (RedUNCI
