Institute for Web Science and Technologies · Universität Koblenz
Institute WeST


Work performed by WeST mainly targets research related to Web Science and Web technologies, Semantic Web and Big Data, Artificial Intelligence and Machine Learning, Network Analysis, Information Retrieval, and User Interfaces. Most research conducted is funded through projects by national or international funding agencies as well as by industry. Third-party projects allow us to bridge the gap between foundational research and applications and to bring cutting-edge technologies into everyday life.

Current Projects


Democracy is constituted by democratic processes that follow rules. For a working democracy it is crucial that citizens have trust in the effectiveness and efficiency of these processes. Here, effectiveness means that democracy reaches its goal by representing the peoples' will, while efficiency means that this is achieved promptly and with little cost. Both effectiveness and efficiency can be increased by digitising democratic processes. [read more...]
