Research Areas
Current Research
- Direct the InterVoice Research Center in the Human Language Technology Research Institute at UTD.
- Co-direct the development of a state-of-the-art Question Answering system that achieved the best performance at TREC-8 (1999), TREC-9 (2000), TREC-11 (2002), TREC-12 (2003) and TREC-13 (2004) QA competitions
- Develop a Knowledge Acquisition from Text (KAT) system that discovers concepts and relations for the purpose of extending WordNet interactively with domain-specific knowledge.
- Develop Word Sense Disambiguation (WSD) methods for open text.
- Develop a new technology for Semantic Indexing and Retrieval of texts that uses word semantics for the purpose of increasing the conciseness and the relevance of the information retrieved.
- Develop a tool for transforming WordNet into a knowledge base by disambiguating the glosses and transforming them in logical and semantic forms.
- Develop a Distributed Question Answering system using a Distributed Java Virtual Machine environment. Study the scalability of some Applied Natural Language Processing algorithms on parallel and distributed computers.
Previous Research
- Worked on Parallel Processing applied to Natural Language Processing including inferences, acquisition of linguistic patterns, and parsers.
- Studied marker-propagation as a new computational paradigm for Artificial Intelligence problems.
- Parallel processing of Rule Based Systems.
- Design of systolic arrays and other array processors.
- Mapping computational algorithms into parallel architectures.
- Microprocessor-based real-time systems.
