This course will be based on the artificial intelligence, machine learning, and linguistics field of natural language processing (NLP, or computational linguistics), to allow building automatic models that can analyze, understand, and generate text. We will cover important traditional topics of NLP such as tagging, parsing, coreference resolution, sentiment analysis, summarization, question-answering, and translation. We will also cover more recent topics of multimodal, grounded, and embodied semantics (i.e., language with vision and speech, for robotics), language generation and dialogue, and interpretable deep learning, etc.

Topics (tentative)


Students not meeting these requirements must receive the explicit permission of the instructor to remain in this course.
