Focus Group: Web-based Systems (Prof. Bizer)
We explore technical and empirical questions concerning the development of global, decentralized information environments. Our current focus is the evolution of the World Wide Web from a medium for the publication of documents into a global dataspace. Our empirical work is accompanying this evolution by monitoring the deployment of Linked Data and Semantic Markup technologies on the Web. Our technical work focuses on integrating data from large numbers of Web data sources and includes topics such as identity resolution, schema matching, information extraction, and data fusion. We apply the developed methods for integrating and cleansing product data from e-shops as well as for creating large-scale knowledge bases.
