Building new business information systems from reusable components is today an approach widely adopted and used. Using this approach in analysis and design phases presents a great interest and requires the use of a particular class of components called Business Components (BC). Business Components are today developed by several manufacturers and are available in many repositories. However, reusing and integrating them in a new Information System requires detection and resolution of semantic conflicts. Moreover, most of integration and semantic conflict resolution systems rely on ontology alignment methods based on domain ontology. This work is positioned at the intersection of two research areas: Integration of reusable Business Components and alignment of ontologies for semantic conflict resolution. Our contribution concerns both the proposal of a BC integration solution based on ontologies alignment and a method for enriching the domain ontology used as a support for alignment.Comment: IEEE New Technologies of Distributed Systems (NOTERE), 2011 11th Annual International Conference; ISSN: 2162-1896 Print ISBN: 978-1-4577-0729-2 INSPEC Accession Number: 12122775 201

Ontology Alignment (OA) identifies semantically matching of different entities, OA continues to attract great attention within the database, information system and artificial intelligence communities. OA used to solve the semantic heterogeneity and hide the complexity of retrieving entities of heterogeneous source. That's why we rely on the OA for resolving semantic conflict during design phase of information system, particularly in semantic integration of Business Components (BC). Our contribution concerns a solution for the integration of BC based on the ontologies alignment in order to support information system designers.
