research group
My research group is the Language and Information Technologies group (LIT@UNT).
research interests
My research interests are in Natural Language Processing, Machine Learning, and Information Retrieval. I am currently working on:
Lexical Semantics (including: semantic similarity, word sense disambiguation, semantic parsing)
Graph-based Algorithms for Natural Language Processing (with applications to text summarization, word sense disambiguation, keyphrase extraction)
Building and Exploiting Parallel Texts, Multilingual NLP
Sentiment and Subjectivity Analysis, Computational Humour
Building Annotated Corpora with Volunteer Contributions over the Web
My research projects are funded by the National Science Foundation, Google, the Texas Advanced Research Program, and ARDA-AQUAINT.
