Ontologies being shared formal specifications of a domain, are an important lever for developing meaningful internet systems. However, the problem is not in what ontologies are, but how they become operationally relevant and sustainable over longer periods of time. Fact-oriented and layered approaches such as DOGMA have been successful in facilitating… (More)
The " living " ontologies that will furnish the Semantic Web are lacking. The problem is that in ontology engineering practice, the underlying method-ological and organisational principles to involve the community are mostly ignored. Each of the involved activities in the community-based ontology evolution methodology require certain skills and tools which… (More)
The Flemish public administration aims to integrate and publish all research information on a portal. Information is currently stored according to the CERIF standard modeled in (E)ER and aimed at extensibility. Solutions exist to easily publish data from databases in RDF, but ontologies need to be constructed to render those meaningful. In order to publish… (More)
Ontologies for enabling semantic interoperability is one of the branches in which agreement between a heterogeneous group of stakeholders is of vital importance. As agreements are the result of interactions, appropriate methods should take into account the natural language used by the community during those interactions. In this article, we first extend a… (More)
In this paper, we present the GOSPL application that supports communities during the ontology engineering process by exploiting Social Web technologies and natural language. The resulting knowledge can then be transformed into RDF(S).
The Do-It-Yourself (DIY) culture has been continuously articulated since mid-1920s. The goal of DIY has been gradually shifted from the solution of the " time-rich and money-poor " situation into the confirmation of personal creativities and the needs of outsourcing and social contact. This paper addresses the design of a DIY environment for managing data… (More)
Semantic Web, Social Web, and new economic challenges are causing major shifts in the pervasive fabric that the internet has become, in particular for the business world. The internet's new role as participatory medium and its ubiquity lead to dense tri-sortal communities of humans and businesses mixed with computer systems, and semantically interoperating… (More)
