Collaborative activities support techniques: from business process implementation to dynamic deployment management

4International audienceThis special issue presents an extended version of seven articles selected from WETICE 2012. The extended articles report on research about various topics to support collaborative activities including business process, coordination, information sharing, orchestration, ontologies, decision making and dynamic deployment. The first article, from Pankaj Goyal and Rao Mikkilineni, presents a new approach to implement π-calculus mobility using DIME network architecture; it is shown how process mobility is an inherent capability of DIMEs. The issue of inter-organizational process management in distributed collaborative activities is addressed by the second article from Jörn Franke and François Charoy. In the third article, Rodrigo Bonacin et al. propose a modeling solution for pragmatic aspects of communication acts using SemWeb technologies. The problem of service composition and particularly the automatic transformation from choreography to orchestration is addressed by the fourth article from Sirine Rebai et al. The fifth article from Ghada Gharbi et al. tackles self-configuring and self-adapting information networks using an autonomic architecture based on ontological decision models. A web-based data exploration in spatial decisional processes supported by Spatial Decision Support System (SDSS) is described in the sixth article from Michele Argiolas et al. The last article, from Mohamed Nadhmi Miladi et al., addresses the problem of pervasive systems adaptation of their deployed architecture regarding to continuous changes in everyday user's requirements
