The Natural Language Processing (NLP) Group at Warwick is comprised of PhD and postdoctoral students, professors and others who are interested in solving computational problems related to the understanding of human language. This encompasses a wide range of topics including sentiment analysis, topic/event extraction, question answering, cross-modal retrieval, text illustration, social media analysis and many more, typically approached with machine learning.
