  • Explorator - a tool for exploring RDF data by direct manipulation. Explorator’s web interface allows users to explore a semi-structured RDF database to both gain knowledge and answer specific questions about a domain, through browsing, search, and exploration mechanisms.
  • Rexplorator - a tool for exploring RDF data by direct manipulation, as an extension of Explorator. RExplorator’s web interface follows Explorator's interface which allows users to explore a semi-structured RDF database to both gain knowledge and answer specific questions about a domain, through browsing, search, and exploration mechanisms. In addition, RExplorator allows users to define operands in queries to be parameters; connect results of queries to parameters in other queries; save inter-related sets of queries as a "use-case" called workbench - like a tab in Excel; define customized browsing interfaces to sets of queries; import previously defined workbenches for reuse; save workbenches for reuse later.

Web-based Collaborative Virtual Environments G1. Investigate the Web as a means for eScience and eLearning through CVEs

G2. Interactive storytelling for Web-based collaborative virtual worlds

G3. Interactive storytelling for cultural content production and e-learning in the Web

  • Fluid Web and Componere - The challenge in this research project is to conceive an authoring approach designed for the Web 2.0, including an authoring tool. It takes advantage of multimedia content and software routines, which are increasingly becoming available on-line, and are delivered on demand by embeddable and mashup-enabled modules -- e.g. video streaming, slide show of photos, interactive maps. This demo application shows our approach to encapsulate these resources behind homogeneous interfaces of components, which act as composable building blocks apt to be smoothly mixed with Web documents.

Research on the Web of Data at the INCT for Web Science (Talk presented at the Workshop of the InWeb - INCT for the Web on Dec. 6th, 2011).

The Web of Data consists of interlinked data, published in a standard format and using uniform identifiers. It provides a simple strategy to describe and publish data openly, circumventing some of the typical problems faced by database federations or by databases available on the Web. However, publishing and accessing large datasets on the Web of Data poses interesting challenges. Furthermore, the relationship between the technology that supports the Web of Data and the current technology to publish databases on the Web is still poorly resolved. In this presentation, we will first give a brief overview of research at the INCT of Web Science. Then, we survey the key concepts and technologies that support the Web of Data. Finally, we concentrate on some of the recent research on this topic carried out at the INCT of Web Science and outline future work.

  • New features implemented in Tangram-II tool:
    • The general topic of Random Walks on graphs have been extensively used to obtain measures of interest on social networks such as centrality, etc. The "random surfing model" is, in fact, a discrete time markov chain. The new features implemented in Tangram-II tool allows the modeler to analyze an important property of a markov chain: ergodicity. This feature can be used, for instance, in models of the web and p2p systems.
