This paper proposes a new method for managing the use of ontologies in the context of a Virtual Breeding Environment. This research work focus is on the dissolution phase of a Virtual Enterprise or Collaborative Network, where ontology segmentation techniques are user to enrich the VBE's ontology library. Firstly, an overview of the process of ontology composition and decomposition is given and...

In recent days, social networks are creating huge amounts of data that need to be managed in intelligent ways. Ontologies always play important roles in these contexts: users and social objects may refer to concepts and this can provide efficient methods to store, retrieve and recommend contents. Everything, however, relies on the concept of interaction.

Communities on the Web capture, represent, and evolve their knowledge using ontologies, either explicitly or implicitly. The Gene Ontology project is a typical and advanced case study of a community-driven ontology creation and evolution. We use this case study to derive and illustrate factors that limit dynamic knowledge sharing in community environments. Specifically, we analyze ontology evol...

The problem of merging several ontologies has important applications in the Semantic Web, medical ontology engineering, and other domains where information from several distinct sources needs to be integrated in a coherent manner. We propose to view ontology merging as a problem of social choice, i.e., as a problem of aggregating the input of a set of individuals into an adequate collective dec...

Social Semantic Web aims at combining approaches and technologies from both Social and Semantic Web. While Social Web sites provide a rich source of unstructured information, what makes its automatic processing very limited, Semantic Web aims at giving a welldefined meaning to the Web information, facilitating its sharing and processing. Multilinguality is an emergent aspect to be considered in...

The gap between advanced statistical approaches and epistemological discussion is certainly one of the most important problems in psychometrics to really improve psychological measures. An important issue in measurement models in social science is the debate about formative measurement models. For some years, the debate has been essentially focused on methodological issues. We aim in this short...

Increasingly media are asserting themselves as live. In television, this has been an important strategy and recently it has been employed by new media platforms such as Facebook, Periscope and Snapchat. This commentary explains the revival of live media by exploring the meaning and operations of the concept and argues the continued relevance of the concept for the study of social media. Traditi...

Critical Realism (CR) states that knowledge (epistemology) is different from being or existence (ontology). There is a reality (unobservable structures) which exists independent of human thought. Critical realists believe that these unobservable structures cause observable events. Therefore, the social world can be understood only if people understand the structures that generate events. This i...
