Research Interest:
-
Statistical approaches and computational models for Natural Language Processing (NLP) and Computational Linguistics.
Interdisciplinary research connecting Natural Language Processing with Computer Vision, Psychology, and Cognitive Science.
Below listed are a few themes that intertwine my research so far, and
click here for more detailed description.
- Natural Language Generation from Images
With Prof. Tamara Berg and Alex Berg, we are investigating how to compose natural language descriptions from images [KPDLCBB11, LKBBC11].
- Opinion & Sentiment Analysis
(1) Lexicon Induction and Adaptation for Sentiment Analysis [CC09, FBC11].
(2) Analysis in light of Compositional Semantics [CC08, CFGJMP10].
(3) Fine-Grained Opinion Analysis [CC10, BCC07, CBC06, CCRP05].
Some of above work been employed by Appinions (appinions.com), a start-up company co-founded by Prof. Claire Cardie.
- Stylometric Analysis
Language is a window into people's minds, and stylometric analysis can be used as a tool for understanding the intent of individual writers, as well as societal characteristics reflected in human language. So far we have looked at gender attribution [SGC11], deceptive opinion spam detection [OCCH11], and Wikipedia vandalism detection [HHSJC11]. - Opinion & Sentiment Analysis
