Abstract
Looking at collaborative networks of organizations as social-technical systems, information and knowledge sharing implies sharing a set of common conceptual structures across organizations. Through this paper, we describe a case study on how to construct meaningful collective conceptualizations by means of a new approach based on conceptual blending theory.

Abstract
Current knowledge about the early phases of ontology construction is insufficient to support methods and techniques for a collaborative construction of a conceptualization. Following an approach inspired in cognitive semantics, the application and extension of the Conceptual Blending Theory (CBT) to the realm of collaborative semantic tools is proposed. A formal framework is presented together with some examples in the collaborative networks context. A collaborative semantic architecture is presented. This architecture supports the two components of the proposed method: collective conceptualization and consensus reaching.

Abstract
This paper presents our method to support the collaborative conceptualisation process focusing our strategy for building consensus in the context of collaborative networks. This new strategy comes from the application of the results and recommendations obtained in an experimental evaluation performed in the scope of a large European project in the area of industrial engineering. The usage of our strategy and the collaborative platform supporting semantic consensus building in the scope of the European research project H-Know is described.

Abstract
Ontologies are a technological key factor regarding the knowledge management domain. This paper presents a graphical-based knowledge representation approach using concept maps towards creating a formal work organization ontology, which was translated into a Content Management System in order to manage the work design information. Some aspects related with the advantages of visual approaches for collaborative development of ontologies are discussed.

Abstract
Collaborative conceptualisation processes are pervasive to most technical and professional activities, but are seldom addressed explicitly due to the lack of theoretical and practical methods and tools to support it. However, it seems not to be a popular research topic in knowledge representation or its sub-areas such as ontology engineering. Our view is that collaboration between stakeholders for specifying an ontology should be addressed at the conceptual, semi-formal level, in order to foster a collective learning of the domain and reaching agreements about its representation. We developed a method to support conceptual integration based in the conceptual blending theory - ColBlend - and implemented it in a collaborative modelling environment. This "conceptual modelling environment - conceptME" supports teams of specialist and facilitators in eliciting conceptual structures with the help of collaborative model editing and terminology services. Conceptual integration and agreements are achieved through the ColBlend method. This paper overviews ColBlend and ConceptME and describes in detail a test case.

Abstract
A case study involving a new method to support the collaborative construction of semantic artefacts in an inter-organizational context is described. The method aims at being applied, in particular, in the early phases of ontology development. We share the view that the development of semantic artefacts in collaborative networks of organizations should be based on a continuous construction of meaning, rather than pursuing the delivery of highly formalized accounts of domains. For that, our research is directed to the application of cognitive semantics results, specifically by developing and extending the Conceptual Blending Theory to cope with the socio-cognitive aspects of inter-organizational ontology development. An evaluation experiment for this method is accomplished in the scope of a large European project in the area of industrial engineering. The method evaluation and its results are described.
