Dan Moldovan

Dan Moldovan is a Professor in the Department of Computer Science at The University of Texas at Dallas, within the Erik Jonsson School of Engineering and Computer Science. He leads the InterVoice Research Center in the Human Language Technology Research Institute and has played a pivotal role in advancing question answering technologies, achieving top performance in multiple TREC evaluations (TREC-8 to TREC-13).

Education:

• Ph.D. in Electrical Engineering and Computer Science, Columbia University (1978)
• M.S. in Electrical Engineering and Computer Science, Columbia University (1974)
• Diploma Engineer in Electrical Engineering, Polytechnic Institute of Bucharest (1969)

His research centers on Natural Language Processing and Artificial Intelligence, with major contributions in Question Answering Systems, Knowledge Acquisition from Text (KAT), Word Sense Disambiguation, and Semantic Indexing and Retrieval. He has developed systems to enrich WordNet with domain knowledge and transform it into a logical knowledge base. His work also explores distributed and parallel processing for scalable NLP algorithms.

The recent publications (2005–2007) highlight his focus on semantic reasoning, multilingual QA, validation of answers using logic provers like COGEX, and the semantics of noun compounds. These works reflect a strong trend toward deep semantic understanding, contextual reasoning, and integration of logic in NLP systems.

Scientific Awards:

• Best performance in TREC-8 (1999), TREC-9 (2000), TREC-11 (2002), TREC-12 (2003), and TREC-13 (2004) QA competitions

Dan Moldovan has advised numerous research projects and led major initiatives such as Extended WordNet and the development of PowerAnswer. He has secured significant research support through appointments and leadership roles across institutions. His work in distributed NLP and parallel processing of rule-based systems reflects a long-standing interest in scalable AI architectures.

He has directed several key research labs:

• InterVoice Research Center, UTD
• Parallel and Distributed Computer Systems Laboratory, University of Southern California
• Parallel Knowledge Processing Laboratory, University of Southern California
