The Web-based Systems Group at the University of Mannheim explores technical and economic questions concerning the development of global, decentralized information environments. The current main topics of our research are:

  • The evolution of the World Wide Web from a medium for the publication of textual documents into a medium for sharing structured data, as well as the role of Linked Data technologies within this transition.
  • The shift from classic data integration architectures to Enterprise Data Spaces which provide for the flexible, pay-as-you-go integration of large numbers of internal and external data sources.

We contribute to various open data publishing and open source software projects including the W3C Linking Open Data (LOD)  project which coordinates the extension of the Web with a global data space by publishing open-license datasets as RDF on the Web and by setting data links between items within different data sources; the DBpedia project which  extracts a large multilingual knowledge base from Wikipedia; and the Web Data Commons project which extracts structured information from over 1.5 billion web pages. Our open source software projects include the LDIF – Linked Data Integration Framework , the Silk – Link Discovery Framework, as well as the D2RQ Platform.

We participate in the following third-party funded research projects: LOD2 - Creating Knowledge out of Interlinked Data, a EU-FP7-IP project which develops tools and methodologies for exposing and managing large amounts of structured data on the Web; the DM2E –Digitized Manuscripts to Europeana project which develops an interoperability infrastructure for converting library metadata from a diverse range of source formats into the Europeana Data Model (EDM), and the PlanetData Network of Excellence which establishes a European community of researchers around the topic of large-scale data management.
