Research Interest

My research interests are in Natural Language Processing, Multimodal Processing, and Information Retrieval using Machine Learning. Research topics that I have planned to work on in the future include:

• Computational socio-linguistics (cross-cultural value learning, text-based geo location, language-based modeling of worldview, multi-modal personality detection, deception detection)

• Multimodal sensing and tracking of human behavior (deception, affect, stress, alertness)

• Joint modeling of language and vision (text-video question answering, text-image similarity, image annotation)

• Lexical semantics (semantic similarity, word sense disambiguation, lexical substitution)

• Graph-based algorithms for natural language processing (text summarization, word sense disambiguation, keyphrase extraction, category assignment)

• Multilingual natural language processing.

• Multilingual subjectivity, sentiment, and emotion analysis computational humor.
