What is this class about?

Natural language processing (NLP) is increasingly driven by statistical and neural methods. These techniques are leveraged in many everyday applications, including intelligent virtual assistants (e.g., Siri or Alexa), machine translation systems (e.g., Google Translate), and language models (such as those used for predictive text). This class will introduce advanced topics in statistical and neural NLP, and provide an overview of active research in those topic areas, through a combination of readings, paper presentations and critiques, a midterm exam, and a semester-long project. Topics covered will include logistic regression, vector semantics, neural networks, coreference resolution, discourse coherence, language modeling, language generation, figurative language processing, and multimodal NLP, among others.

Textbooks

Readings for the first part of the semester will be drawn from the following source:
- Daniel Jurafsky and James H Martin. Speech and Language Processing (3rd Edition). Draft, 2019.

Note that this resource is a draft of the upcoming third edition of Speech and Language Processing. Chapter order and content is subject to change throughout the semester (I'll try to update the course website whenever I notice this occurring, but feel free to ping me if you think something seems out of date). Readings for the second part of the semester will be drawn primarily from journals and conference proceedings. Some suggested papers for each topic in the second part of the semester are provided in the course syllabus. You are perfectly welcome to present a paper that is not in the list of suggestions, as long as I approve it.

Assignments and Exams

This course acts as a middle ground between UIC's introductory, lecture-based NLP course (CS 421) and the advanced, seminar-style NLP courses (CS 594) periodically offered by the department. Most of the coursework will be closer to what you would expect to find in a seminar-style course, but the general format of the class will contain elements of both. For the first portion of the semester, traditional lectures will be given about different statistical and neural techniques; this portion will conclude with a midterm exam. For the second portion of the semester, students will present and critique research from recent NLP papers. Some further details about the work you will be expected to complete for this course are provided below: Grading rubrics will be posted on Blackboard. Final course grades will be determined according to the following breakdown:
