Summary: Business processes define how organizations perform their activities to deliver
results according to established goals. These activities are usually supported by different applications of one or more organizations. These applications are often developed at different time, by different groups and with no concern for integration. As a consequence, organizations have to deal with integration problems to allow for a good communication between applications at data, service and process layers. In this context, semantic conflicts should be addressed to ensure that application integration will be properly performed. In
order to properly support the business processes involved in the integration, it is important to address semantic aspects related to the process layer. Among tools used to assign semantics, ontologies can be used as an interlingua to map concepts used by different applications and organizations. Considering that semantic integration is a complex activity, the use of an approach to guide application integration can structure the integration process in different abstraction levels and provide guidelines on how to perform the various integration activities. In this sense, in (CALHAU, 2011) was defined the Ontologybased Approach for Semantic Integration (OBA-SI), an approach that uses ontologies to perform semantic integration of applications. In this work, it is proposed an improvement of OBA-SI, focusing on integration at process layer. For that, it was developed the Business Process Ontology, which supports the integration by providing the main concepts that should be considered to communication among processes. Furthermore, some phases of OBA-SI were refined and relations between the integration layers were made explicit. As
a consequence, conceptual models of processes and applications to be integrated are analyzed in the light of the Business Process Ontology and the task and domain ontologies, which are used to assign semantics to shared items. To evaluate the OBA-SI evolution proposed in this work, it was used to integrate applications aiming to support in an integrated manner the Problem Management and Software Configuration Management processes.
