Chapter: Formalising restructuring operators in a specification process
[show abstract] [hide abstract]
ABSTRACT: Writing good specifications is often much more difficult than writing good programs to meet them. A major issue concerns the process by which specifications are constructed. A formalisation of the process may be viewed as a sequence of operator applications. In this paper, we present a specific category of operators called restructuring operators. These operators are required to describe some structural transformations which can be applied during the specification process in order to enhance the final specification product with qualities such as modularity, minimality and absence of redundancy. We present a specification language including some restructuring operators, the latter being formally expressed in terms of algebraic grounds. Finally, we suggest some uses of these restructuring operators.04/2006: pages 159-171; -

Conference Proceeding: An Extension of OWL-S with Quality Standards.
[show abstract] [hide abstract]
ABSTRACT: With the increasing amount of Web Services available on the Web, Web Services discovery issues are becoming increasingly important. Since current Web Services standard technologies (e.g. UDDI) only provide syntactic descriptions of Web Services (mainly their signatures), semantic discovery approaches based on ontologies (e.g. OWL-S) have been developed. These approaches lead to more precise descriptions of Web Services functionalities, but they provide few mechanisms to capture non functional aspects of Web Services collectively referred as Quality of Services (QoS). To fill this gap, some works have proposed Web Services discovery approaches based on QoS ontologies. However these approaches do not take into account existing standards about software quality and the relationships that can be established between them. Yet, these standards could be used as a shared understanding between services providers and customers and thus, they would ease the Web Services discovery process. In this article we first propose an extension of OWL-S to describe QoS according to one or many quality standards. Then, we develop an approach based on this extension of OWL-S to improve the Web Services discovery process. This approach is based on an extension of SPARQL that simplifies expression of Web Services discovery queries. Relationships between standards are used to return Web Services even if they are described with quality properties defined in an other standard that the one used to express queries. Finally, non functional requirements can be expressed as user preferences. Thus, they can be used to rank Web Services fulfilling functional requirements during the Web Service discovery process.Proceedings of the Fourth IEEE International Conference on Research Challenges in Information Science, RCIS 2010, Nice, France, May 19-21, 2010; 01/2010
