This course provides an introduction to the field of natural language processing (NLP) - the creation of computer programs that can understand, generate, and learn natural language. We will use natural language understanding as a vehicle to introduce the three major subfields of NLP: syntax (which concerns itself with determining the structure of a sentence), semantics (which concerns itself with determining the explicit meaning of a single sentence), and pragmatics (which concerns itself with deriving the implicit meaning of a sentence when it is used in a specific discourse context). The course will introduce both knowledge-based and statistical methods for NLP, and will illustate the use of such methods in a variety of application areas.
Speech and Language Processing by Jurafsky and Martin. It should be available from the Campus bookstore, as well as from Amazon and other online providers.
Errata for the text
Be sure to get the linguistic background handouts from the first two books.
Concepts taught in class will be reinforced with assignments (both problem sets and programming), and exams.
Grades are now available. You were a great class and I enjoyed the semester! I hope you did too.
I will be teaching a seminar next semester which is a natural follow-up to this course. The class will involve the presentation and discussion of papers in discourse and dialogue. It will meet in LRDC 814 (a conference room), MW 2:00 PM - 03:20 PM. Details can be found here.

I understand that some people are having trouble getting the ngram software to work... If you have a cs account, use the machines bert or ernie. Otherwise, Stefanie Bruninghaus has provided her fixes (thanks Steffi!), which seems to work for some other machines (README, Stats, count-unigrams.pl).
