* Announcement [#wf729b28]

- We revised the course plan in P2 of [[this PDF:http://www.chokkan.org/lectures/2016nlp/p/01nlp.pdf]].
- No class on Nov 10.
- The next class will be held on Nov 17 at Room 205 (not at Computer Room as initially announced).

* Summary [#l832384b]

The most important means for communication are the languages that we use everyday, like Japanese and English.
In general, an application of computer to processing languages is called computational linguistics.
This course will focus on many of the core technologies and techniques used in computational linguistics, ranging from part-of-speech tagging, syntactic parsing to computational semantics and discourse.

* Instructors [#a23262ff]
- [[Kentaro Inui:http://www.cl.ecei.tohoku.ac.jp/~inui/]] (Parts II and III)
- [[Naoaki Okazaki:http://www.chokkan.org/]] (Parts I and II)
