Welcome to NLPFin Group!

The Natural Language Processing in Finance Group (NLPFin) is led by Dr. Chung-Chi Chen. Our main research lies on the intersection of Natural Language Processing and Finance. We aim to improve the unstructured data understanding and generation in the financial field and further adopt the results in FinTech applications.


NLPFin Group is now recruiting interns, research assistants, and postdocs who are interested in applying NLP in financial and legal documents. Below are some of the topics we are recently interested in, and the research is included but is not limited to these directions. Our members can work in the office of either NLP Lab, National Taiwan University, Taiwan, or Artificial Intelligence Research Center (AIRC), AIST, Japan. Remote work from abroad is also acceptable. Please contact Chung-Chi Chen by emailing c.c.chen@acm.org if you are interested in.
