In this paper we outline the design and implementation of the eDialogos Consensus process and platform to support wide-scale collaborative decision making. We present the design space and choices made and perform a conceptual alignement of the domains this space entails, based on the use of the eDialogos Consensus ontology as a crystallization point for platform design and implementation as well as interoperability with existing solutions. We also present a metric for calculating agreement on the issues under debate in the platform, incorporating argumentation structure and user feedback.
In this paper we describe the application of various Semantic Web technologies and their combination with emerging Web 2.0 use patterns in the eParticipation domain and show how they are used in an operational system for the Regional Government of the Prefecture of Samos, Greece. We present parts of the system that are based on Semantic Web technology and how they are merged with a Web 2.0 philosophy and explain the benefits of this approach, as showcased by applications for annotating, searching, browsing and cross-referencing content in eParticipation communities.
The liberalization of the electricity market in the European Union is a process of significant importance that aims at creating an efficient deregulated internal electricity market within the Union. An important challenge towards that end is definitely the development of effective market mechanisms and regulations that will comprise the operational framework of the market. Equally important, however, we consider the development of an interoperability framework that will enable the effective and unproblematic interaction between the market participants at both human and system level. Towards that direction we propose in this paper the Electricity Market Ontology (ELMO), an ontological model that provides a shared, common understanding of concepts and procedures regarding the electricity market operation. ELMO has been developed for the Hellenic Transmission System Operator (HTSO) and it is currently used by the organization for providing intelligent information access services to people interested in the market.
In the modern business environment, the capability of an enterprise to generate value from its business knowledge influences in an increasingly important way its competitiveness. Towards this direction, knowledge-based systems can be a very effective tool for enhancing the productivity of knowledge workers by providing them with advanced knowledge processing capabilities. In this paper we describe such a system which utilizes organizational and domain knowledge in order to support consultants in the process of evaluating calls for tender.
