LING-2040/4400 | Computational Language Processing (a.k.a. Introduction to Natural Language Processing)

Amir Zeldes Undergraduate & Graduate

This course will introduce students to the basics of Natural Language Processing (NLP), a field that combines linguistics and computer science to produce applications, such as generative AI, that are profoundly impacting our society. We will cover a range of topics that form the basis of these exciting technological advances and will provide students with a platform for future study and research in this area. We will learn to implement simple representations such as finite-state techniques, n-gram models, and topic models in the Python programming language. Previous knowledge of Python is not required, but students should be prepared to invest the necessary time and effort to become proficient over the semester. Students who take this course will gain a thorough understanding of the fundamental methods used in natural language understanding, along with an ability to assess the strengths and weaknesses of natural language technologies based on these methods.

LING-4401/DSAN-5400 | Computational Linguistics with Advanced Python

Trevor Adriaanse Upperclass Undergraduate & Graduate

This course presents topics in Natural Language Processing (NLP) and Python programming for both text processing and analysis. The goal of this class is to explore both classical and modern techniques in NLP, with emphasis on hands-on application. We will examine topics such as text classification, model evaluation, nearest neighbors, and distributed representations. Applications include authorship identification, structured prediction, and semantic textual similarity, to name a few.

Programming topics include Python best practices, scientific computing libraries (e.g., NumPy, sklearn, etc.), exception handling, object-oriented programming, and more. By the end of this course, students will be able to program proficiently in Python, with enough comfort to reference software documentation and pseudocode to write sophisticated programs from scratch.

Requirements: Basic Python programming skills are required (for example satisfied by LING-4400, Computational Language Processing/Intro to NLP)

LING-4424 | All About Prepositions

Nathan Schneider Upperclass Undergraduate & Graduate

This course will take on the grammatical category of prepositions, which are hands-down some of the most intriguing and beguiling words once you get to know them. (How many prepositions are there in the previous sentence? The answer may surprise you!) We will look at their syntactic and semantic versatility in English and how they vary across languages. We will explore how they denote relations in space and time, as well as many other kinds of meanings. We will see why they are so hard to learn in a second language, and why they are difficult to define in dictionaries and teach to computers. The course will be project-based, including a significant project on a language other than English.

Prerequisites: Some background in syntactic description, e.g. satisfied by LING-2020, LING-4427, or LING-5127

LING-4427 | Computational Corpus Linguistics

Amir Zeldes Upperclass Undergraduate & Graduate

Digital linguistic corpora, i.e. electronic collections of written, spoken or multimodal language data, have become an increasingly important source of empirical information for theoretical and applied linguistics in recent years. This course is meant as a theoretically founded, practical introduction to corpus work with a broad selection of data, including non-standardized varieties such as language on the Internet, learner corpora and historical corpora. We will discuss issues of corpus design, annotation and evaluation using quantitative methods and both manual and automatic annotation tools for different levels of linguistic analysis, from parts-of-speech, through syntax to discourse annotation. Students in this course participate in building the corpus described here: https://corpling.uis.georgetown.edu/gum/

LING-4480 | Computational Linguistics Research Methods

Ethan Wilcox Upperclass Undergraduate & Graduate

Computational Linguistics is a fast-growing and fast-moving field. This course is intended to give advanced undergraduate and graduate students practice conducting original research in computational linguistics and to enhance their research and communication skills. It will serve as a platform for students to pursue an independent research project with guidance and oversight from faculty and peers. Students will be expected to bring their own pre-existing research topics/questions to the class. Over the course of the semester, they will select and present key research papers pertinent to their topic, and develop the project with the goal of writing an ACL-style conference proceedings paper. In addition to hands-on research, this class will provide a venue for students to learn CL-related skills that often fall through the cracks of other, content-focused courses. Possible workshop topics include data annotation, LaTeX, and working with pretrained language models, as well as communication skills such as poster and slide design. As a hands-on course whose content changes based on the instructor and students, this course can be repeated for credit.

DSAN-5800 | Advanced NLP

Chris Larson Graduate

This course provides a formalism for understanding the statistical machine learning methods that have come to dominate natural language processing. Divided into three core modules, the course explores (i) how language understanding is framed as a tractable statistical inference problem, (ii) a formal yet practical treatment of the DNN architectures and learning algorithms used in NLP, and (iii) how these components are leveraged in modern AI systems such as information retrieval, recommender systems, and conversational agents. In exploring these topics, the course exposes students to the foundational math, practical applications, current research directions, and software design that is critical to gaining proficiency as an NLP/ML practitioner. The course culminates in a capstone project, conducted over its final six weeks, in which students apply NLP to an interesting problem of their choosing. In past semesters students have built chatbots, code completion tools, stock trading algorithms, just to name a few. This course assumes a basic understanding of linear algebra, probability theory, first order optimization methods, and proficiency in Python.

This is an advanced course. Suggested prerequisites are DSAN 5000, DSAN 5100 and DSAN 5400. However, first-year students with the necessary math, statistics, and deep learning background will be considered.

COSC/LING-5402 | Empirical Methods in Natural Language Processing

Nathan Schneider Graduate

Systems of communication that come naturally to humans are thoroughly unnatural for computers. For truly robust information technologies, we need to teach computers to unpack our language. Natural language processing (NLP) technologies facilitate semi-intelligent artificial processing of human language text. In particular, techniques for analyzing the grammar and meaning of words and sentences can be used as components within applications such as web search, question answering, and machine translation.

This course introduces fundamental NLP concepts and algorithms, emphasizing the marriage of linguistic corpus resources with statistical and machine learning methods. As such, the course combines elements of linguistics, computer science, and data science. Coursework will consist of lectures, programming assignments (in Python), and a final team project. The course is intended for students who are already comfortable with programming and have some familiarity with probability theory.

ICOS-7712 | Cognitive Science Seminar

Abigail Marsh & Elissa Newport Graduate

A seminar in which graduate students and faculty interested in the cognitive sciences will read and discuss prominent articles across our fields. Can be repeated for credit.
