CSCI 5832: Natural Language Processing
Instructor Fall 2019: James Martin
Natural Language Processing
NLP is about getting computers to perform useful and interesting tasks involving spoken and written human language. NLP is sometimes referred to as Computational Linguistics to emphasize the fact that involves the combination of CS methods with research insights from Linguistics (the study of human language). Practical applications of NLP include question answering, machine translation, information extraction, and interactive dialog systems (both written and spoken). Modern NLP systems rely heavily on methods involving probability, linear algebra and calculus often in combination with machine learning methods.

Readings
We’ll be using draft chapters from the 3rd Edition of Speech and Language Processing by Dan Jurafsky and James H. Martin. You should not need to buy the current edition, draft pdfs of the new chapters will be available from the textbook website. The week-to-week readings are on Moodle
Grading
Grades will be based on a cumulative score as follows:
● Assignments (40%)
● Quizzes (30%; equally weighted)
● Final (30%)
