    ABSTRACT: The fast growth and spread of Web 2.0 environments have demonstrated the great willingness of general Web users to contribute and share various type of content and information. Many very successful web sites currently exist which thrive on the wisdom of the crowd, where web users in general are the sole data providers and curators. The Semantic Web calls for knowledge to be semantically represented using ontologies to allow for better access and sharing of data. However, constructing ontologies collaboratively is not well supported by most existing ontology and knowledge-base editing tools. This has resulted in the recent emergence of a new range of collaborative ontology construction tools with the aim of integrating some Web 2.0 features into the process of structured knowledge construction. This paper provides a survey of the start of the art of these tools, and highlights their significant features and capabilities.

    ABSTRACT: The goal of the work presented here is to introduce community-driven ontology management as a new approach to ontology construction and demonstrate the added value to community portals of being community driven. The three main parts of the work are (i) the development of a framework allowing and motivating collaborative ontology construction and reuse for the end users (a person or a community), (ii) building a prototype on the basis of this specification, namely the People's portal, and (iii) the application of the developed infrastructure to scenarios in semantically-enhanced community portals with the involvement of real users. The development of the framework for community-driven ontology construction is aimed at enriching the established practices for ontology development and population with community-supporting features. The objective of community-driven ontology management is to provide the means and motivations for a large number of users to "weave" and adopt the Semantic Web. The People's portal infrastructure allows end users to define the content structure (i.e., develop ontologies), to populate on-tologies, and to define the ways in which the content is managed on various semantically-enhanced community portals where the infrastructure is applied. An analysis of the functionalities of existing (Semantic) Web community environments and the empirical results obtained in this work are indicative of its feasibility and of the advantages of community-driven ontology construction. In practice, the communities were capable of introducing on the community portals such ontology items as Classes, Subclasses, Properties, Instances, ontology mappings, and of reusing these items afterwards.

    ABSTRACT: The Semantic Web aims to create a web of data where contents can be easily discovered and integrated using metadata. Many ontologies have been proposed over the years in different domains, thus producing a semantic heterogeneity that is difficult to manage. Various automated ontology mapping techniques and tools have been developed to facilitate the bridging and integration of distributed data repositories. Nevertheless, such tools are still in need of human supervision to ensure accuracy. The spread of Web 2.0 approaches demonstrate the possibility and the added value of using collaborative techniques for improving data sharing and consensus reaching. In this paper, we describe our prototype for collaborative ontology mapping and data sharing. The possibility to exploit ontology alignments for querying data is a key capability for data sharing in a networked ontology environment.
