This course will provide an introduction to various techniques in natural language processing with a focus on practical use. Topics will include bag-of-words, English syntactic structures, part-of-speech tagging, parsing algorithms, anaphora/coreference resolution, word representations, deep learning, and a brief introduction to current research.
The course will cover basic implementations in Python as well as APIs and tools for advanced text processing. There will be brief weekly assignments, a midterm exam, and a final project including a programming component, a written report, and a short presentation.

I will conduct lectures over Zoom from the classroom. Students have the option to come in person to lectures, but I will not take attendance. All other components of the course are online. Zoom links can be found on the NYU Classes site.
The weekly assignments will include written portions and Python programming portions.
Homework assignments are due on the NYU Classes site by the indicated due date. Late assignments will not be accepted. If you have extenuating circumstances, please speak to me before the assignment is due. Assignments without submissions will receive a grade of zero. Weekly assignments should take on average one hour per week.
It is allowed (and recommended) to use textbooks, online references, your class notes, and any other references for the assignments. You can also discuss the assignments with other students and the TA. However, the final submission must be your own work. Please cite any sources and collaborators in your submission.
The final project should address a problem by applying existing NLP techniques. Examples include predicting a culture trend using sentiment analysis on Twitter, or figuring out the meanings of emojis in Venmo payments.
The final project will be done in groups of 3 or 4 students. In the case of extreme imbalance in work distribution, grades for each student in the group will be adjusted based on participation. The final project grade will come from five components: statement of interest, proposal, paper draft, presentation, and final paper.
Each student will submit a statement of interest, which is up to a paragraph describing a topic on which you would be interested in doing a project. It is okay at this stage to be unsure or have half-formed ideas. I will then assign students into groups based on topics. Students who don’t submit this statement will be randomly assigned.
Each group will submit a project proposal. The goal for the project proposal is to get feedback on feasibility and check for any anticipated missing pieces. It should be a few paragraphs (up to a page) describing:
- Your idea
- The problem you are solving
- Where you will get data
- What NLP you will do
- How you will evaluate your methods
- Anything else needed to understand your project
Each group will submit a paper draft, which is essentially the first half of the final paper. There is no length guideline, and you will not be penalized for lack of results at this stage. It should:
- introduce and motivate your problem and solution
- explain how others have solved similar problems (if applicable)
- describe your dataset
- explain any results
Each group will give a 9-minute presentation on Zoom on December 7. It is recommended to have one person share a screen with slides. The presentation should have:
- motivation for the problem
- description of the dataset
- explanation of the NLP and other methods used
- preliminary results
Each group will submit a final paper. The paper should include:
- Introduction / motivation / description of the problem
- Brief description of how others have solved similar problems
- Description of the dataset and where you got it
- Explanation of NLP and other methods used
- Results / discussion of results (Did you solve the problem?)
- Works cited
We will follow NYU’s policy for acadmic integrity for students, which states the repercussions of academic dishonesty. However, exceptions will be made for students who demonstrate regret within 72 hours.
“If you commit some act that is not reasonable but bring it to the attention of the course’s heads within 72 hours, the course may impose local sanctions that may include an unsatisfactory or failing grade for work submitted, but the course will not refer the matter for further disciplinary action except in cases of repeated acts.”
