Conceptual Modelling with Specific Focus on Service-Oriented Systems

The aim of this special issue of the Journal of Universal Computer Science is to disseminate the results of innovative research in Conceptual Modelling. Its main focus is on the application and role of conceptual modeling techniques in service-oriented systems. In particular we invited the authors of the best papers presented at the Ninth Asia-Pacific Conference on Conceptual Modelling (APCCM) and the Third International Workshop on Conceptual Modelling of Services (CMS) to submit thoroughly revised versions of their contributions to this special issue. APCCM provides an annual forum for disseminating the results of innovative research in information modelling and related areas. In turns, the CMS workshop series provides a more specific forum for presenting and discussing trends and novel ideas in the intersection of the rather new, fast growing services computing and services science paradigms with the well established conceptual modelling area. In addition, an open call for submissions was launched. A total of 14 submissions were received for this special issue. Each submission was reviewed by at least two international experts, and in several cases a second reviewing round
