The many faces of GESIS
Vita
Dimitar Dimitrov is post-doctoral researcher at GESIS and team leader for the team "Information Extraction and Linking" in the Knowledge Technologies for the Social Sciences Department. He studied Computer Science and Software Engineering at HTWG Konstanz, Germany, and obtained his Ph.D. from the University of Koblenz-Landau, Koblenz, Germany. He was a visiting researcher at the Graz University of Technology, Graz, Austria, and at the eXascale Infolab at the University of Fribourg, Fribourg, Switzerland.Service
From an infrastructure and application perspective, Dimitar's work is concerned with applying state-of-the-art research methods to extract information to create innovative research data infrastructures that support social scientists in answering interdisciplinary research questions. Dimitar is also responsible for coordinating data collection activities.Research
Dimitar's research interests involve developing methods for information extraction from social media discourse and scholarly literature data. He serves on programme committees for international conferences, including CIKM, SIGIR, HYPERTEXT, ICWSM, ISWC.Publications
