NLP group: Home

The Cornell NLP group's homepage — Welcome!

We work on a diverse set of projects in natural language processing, computational linguistics, machine learning, and information retrieval.

A small sampling of areas we are interested in are (in alphabetical order): information-extraction, lexicon and grammar induction, paraphrase acquisition, question-answering, sentiment analysis, similarity-based methods, and text summarization.

Want to learn more? Check out the links on the top navigation bar (note especially that information about research is maintained on individual's homepages), left sidebar, and below, or feel free to contact us!
