The Natural Language Processing Lab (NLP-Lab) is focused on theoretical work and implementations of Natural Language Processing (NLP) and Artificial Intelligence (AI) solutions using hybrid approaches, empiricist, neural, probabilistic, and knowledge-driven, with a particular interest in neuro-symbolic modeling. We are also interested in Quantum NLP and AI and NLP combined with Machine Learning (ML) solutions for computer vision and multi-modal information processing. Ultimately, we believe we are getting closer to what Steve Jobs had as a vision in 1985. Watch the video on YouTube.
The NLP-Lab is located at Indiana University at Bloomington. While it is mainly a local group of students and researchers with a strong interest in NLP and AI here in Indiana, it has ties to colleagues all across the country.
During the Fall of 2025, we meet in person every week in Luddy Hall (BLIF) 0002, every Wednesday from 5:30 to 7:00 PM. (See Teams and email announcements for more details.)
The Quantum AI and NLP Study Group meetings are in Luddy Hall (BLIF) 0002 every Thursday from 5:30 to 7:00 PM.
Please contact Damir Cavar if you are interested in joining the NLP-Lab meetings.
