Linguistics 615
Corpus Linguistics
Spring 2013

Course goals Advances in computer technology have revolutionized the ways linguists can approach their data. By using computers, we can access large bodies of text (corpora) and search for the phenomena in which we are interested. In this way, we can uncover complexities in naturally-occurring data and explore issues related to frequency of usage.

In this course, we will investigate some of the following questions, among others: What is a corpus, and what corpora exist? How are corpora developed? How does one search for specific phenomena in corpora? What is a concordancer? Do we need syntactic annotation? Are there programs that do the annotation automatically? Are there tools that help search linguistically annotated corpora?

Meeting time: MW, 4:00-5:15pm

Classroom: Sycamore Hall (SY) 212
(We will likely move some sessions to the lab in Memorial Hall (MM) 401.)

Assignments: There will be approximately one assignment every two weeks. These assignments give you the opportunity to practically explore the topics discussed in class.

Readings: There is a main required textbook we will use. Additionally, there will sometimes be readings available online.

Grading: Grades will be based on:

Final projects Final projects will allow you to explore a research topic of your own interest and how corpus linguistic methods can enhance the research. More details will be given soon, as part of your assignments.

Perl programming Approximately every week, we will have a short lesson (20-30 minutes) on the Perl programming language. This language is useful for writing quick programs to process text, change data formats, access web data, as a front-end for language technology, etc. I assume no previous programming background.

500 Billion Words Workshop It just so happens that there is a Workshop happening April 18–20 here at IU which is relevant to this course, the What Can We Do With 500 Billion Words? workshop (http://mypage.iu.edu/~meldye/workshop/). This is a great chance to hear various speakers talk on working with large data sets. Many talks are on Friday, April 19, so you should book part of that day to attend at least some of the workshop.

Academic Misconduct: Academic misconduct is not allowed in this course. The Indiana University Code of Student Rights, Responsibilities, and Conduct (http://dsa.indiana.edu/Code/) defines academic misconduct as “any activity that tends to undermine the academic integrity of the institution . . . Academic misconduct may involve human, hard-copy, or electronic resources . . . Academic misconduct includes, but is not limited to . . . cheating, fabrication, plagiarism, interference, violation of course rules, and facilitating academic misconduct” (II. G.1-6).

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/).

Schedule We will mix practical sessions with more lecture-based sessions.
