Head of the department MIND ("Multimedia INformation retrieval Dialogue techniques"), which is a research group within the "Cognitive User Interface" (CUI) Division of IPSI;
Lecturer at Technische Hochschule Darmstadt
Current Research Base:
Dr Thiel's primary research and development interests are in information retrieval, intelligent interfaces, hypertext, multimedia, discourse modeling, user modeling, knowledge representation, text analysis and generation. Current projects in MIND focus on cognitive information presentation, integration of speech generation into graphical interaction, intelligent retrieval based on abductive reasoning, cooperative dialogue management based on speech act theory and case based reasoning.
Experience in Research and Development:
Dr Thiel received his M.S. (Diploma) in Computer Science and his Ph.D. degree in Information Science at Department of Computer Science, University of Dortmund, and the Department of Information Science, University of Konstanz, in 1983 and 1990, respectively.
From 1983 to 1988 he was a researcher and lecturer at the Department of Information Science, University of Konstanz. He was a member of the TOPIC/TOPOGRAPHIC project, which resulted in an operational prototype for semantic information retrieval for full texts.
Since 1990, he is Department Manager in GMD-IPSI.
