Short-Term Semantic Consensus: Towards Agile Ontology Specification for Collaborative Networks

Authors
Pereira, C; Sousa, C; Soares, AL;

Publication
LEVERAGING KNOWLEDGE FOR INNOVATION IN COLLABORATIVE NETWORKS

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.

2007

Understanding users' response to ontology based systems in the context of an enterprise sponsored virtual community

Authors
Pereira, C; Silva, M; Fernandes, J; Soares, AL;

Publication
Establishing the Foundation of Collaborative Networks

Abstract
This paper aims at presenting the preliminary results of a research work that seeks to understand the users' response to semantic based technologies, in the context of enterprise sponsored virtual communities. The research follows a qualitative methodology based on an action research approach. It particularly focuses on the socio-cognitive processes that underlie users' learning and acquisition methods when training and interacting with a new knowledge management approach bayed on semantically enabled technologies in a collaborative, and sometimes virtual, learning/working environment. The outcomes of this research are expected to provide an assessment framework for a deeper level understanding of the cognition process in what concerns the evolution of individuals knowledge, opinions, beliefs, and thoughts about ontology based systems.

Supporting Collaborative Conceptualization Tasks through a Semantic Wiki Based Platform

Authors
Sa, C; Pereira, C; Soares, AL;

Publication
ON THE MOVE TO MEANINGFUL INTERNET SYSTEMS: OTM 2010 WORKSHOPS

Abstract
The process of collective development of conceptual models has not been satisfactorily addressed in the knowledge representation research literature. Nevertheless, a shared conceptualization of a given reality is the cornerstone to build semantic artifacts such as ontologies. This paper presents a new platform that implements the Col Blend method, designed to support a collaborative conceptualization process. The platform is based on semantic technologies and proposes a set of functionalities for importing, creating, manipulating, discussing and documenting conceptual models that can act e.g., as the specification of a formal ontology. The platform is being tested and used in two research projects(1).

A method for the collaborative development of shared domain conceptualizations in inter-organizational contexts

Authors

Publication
TKE 2010: Presenting Terminology and Knowledge Engineering Resources Online: Models and Challenges

Abstract
The early phases of setting up information and knowledge management architectures for inter-organizational teams are complex and problematic mainly due to the actor's heterogeneous professional and cultural backgrounds. The big challenge stands on the proper definition, in short-term, of the concepts and relations, which are the basis of the information and knowledge architecture to be common to the collaborative network. Like this, considering a common conceptualization of a given reality as the cornerstone for information and knowledge sharing among a network of social actors, the core problem is how to create suitable socio-technical tools to support the collaborative process of creating semantic artifacts to be operationalized in some short-term business opportunity.

2012

A pragmatic approach to conceptual negotiation support

Authors
Sousa, C; Pereira, C; Soares, AL;

Publication
ICEIS 2012 - Proceedings of the 14th International Conference on Enterprise Information Systems

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.

2009

A socio-semantic approach to the conceptualisation of domains, processes and tasks in large projects

Authors
Pereira, C; Sousa, C; Soares, AL;

Publication
ICEIS 2009 - 11th International Conference on Enterprise Information Systems, Proceedings

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.
