Linguistics 445/ 545 / CSCI B659
Computation and Linguistic Analysis
Spring 2016

Course goals This course will introduce students to computational linguistics (CL) and natural language processing (NLP), a field combining insights from linguistics and computer science. The course is concerned with concepts, models, and algorithms to interpret, generate, and learn natural languages, as well as applications of NLP.

We will look at these different levels of linguistic analysis: morphology, morpho-syntax, syntax, lexical semantics, and to some extent compositional semantics. In so doing, we will move from simple representations of language, such as finite-state techniques and n-gram analysis, to more advanced representations, such as those found in context-free and unification-based parsing. Some emphasis will be placed on parsing techniques in this course.

Course requirements:

Academic Integrity: (from the Dean for Academic Standards and Opportunities)

Academic Integrity: As a student at IU, you are expected to adhere to the standards and policies detailed in the Code of Student Rights, Responsibilities, and Conduct (http://www.iu.edu/~code/). When you submit an assignment with your name on it, you are signifying that the work contained therein is all yours, unless otherwise cited or referenced. Any ideas or materials taken from another source for either written or oral use must be fully acknowledged. If you are unsure about the expectations for completing an assignment or taking a test or exam, be sure to seek clarification beforehand. All suspected violations of the Code will be handled according to University policies. Sanctions for academic misconduct may include a failing grade on the assignment, reduction in your final course grade, a failing grade in the course, among other possibilities, and must include a report to the Dean of Students who may impose additional disciplinary sanctions.

Students with Disabilities: Students who need an accommodation based on the impact of a disability should contact me to arrange an appointment as soon as possible to discuss the course format, to anticipate needs, and to explore potential accommodations.

I rely on Disability Services for Students for assistance in verifying the need for accommodations and developing accommodation strategies. Students who have not previously contacted Disability Services are encouraged to do so (812-855-7578; http://www.indiana.edu/~iubdss/).
