Non-functional requirements are emerging as one of the most crucial factors for successful information system development in service-oriented organizations. Non-functional requirements involve not only software characteristics but also numerous organizational elements. This study proposes a conflict analysis method for non-functional requirements of information systems. This method includes ontologies,...
Comprehensive testing is necessary to ensure the quality of complex Web services that are loosely coupled, dynamic bound and integrated through standard protocols. Testing of such web services can be however very expensive due to the diversified user requirements and the large numbers of service combinations delivered by the open platform. Group testing was introduced in our previous research as a...
In the current globalized world, characterized by strong Web based interactions, relationships between people and organizations are subject to fast changes. This situation justifies the need for an approach that can capture business changes and quickly implement them into computational systems.

Current fashion systems to interconnect large software architectures are moving toward SOA based solutions. This new paradigm for designing system can be improved, in our opinion, by using semantics. Semantics can a play a main role in boosting interoperability thanks to current technologies to express knowledge and to describe semantic Web services (SWS). This paper tackles the provision of a Software...
