Winter Semester 2021/22: "Legal Data Science and Informatics" (IN2395)

Master's Level Elective Module

4 SWS / 6 credits

Instructor: Matthias Grabmair (matthias.grabmair@tum.de)

Session times:  Tuesday & Thursday at 14:00-16:00 (starting on time)

Media: Course will take place in presence if the public health situation allows with materials available on Moodle; course sessions will be recorded when possible and made available via Moodle

Content Outline

The way lawyers, Judges, corporate legal counsel, government agencies, and businesses engage with legal systems, requirements, and processes is increasingly influenced by technology. Prominent areas of practical interest are the intelligent search and analysis of legal documents, the role of machine learning in supporting legal decision making, and modeling legal processes using expertise encoded in formal rule systems. This module provides an overview, and practical introduction, to the research and state of the art in applying data science and artificial intelligence methods to tasks and problems arising in and around the public and private practice of law. 

Legal decision making, legal data, and legal documents in particular challenge many mainstream modeling and analysis techniques. Hence, the module is intended to be taken by (1) broadly interested students from technical majors interested in challenging interdisciplinary work, and (2) political science / business / law students seeking to enhance their understanding of how new technologies can shape their field.

The module consists of a mix of lecture and discussions sessions following a thematic progression:

  • Introduction to legal systems, legal reasoning, and the impact of AI on legal practice
  • Basics of machine learning and natural language processing (NLP) (intended as a primer/refresher for nontechnical students; largely tailored to specific legal applications contexts)
  • Case- and rule-based formalisms of legal reasoning
  • Legal data analytics, including case outcome prediction and empirical legal studies
  • Equal treatment imperatives and fair machine learning
  • Applications of NLP on legal text, including information retrieval and text-based outcome prediction

Module sessions will cover concepts in an example-driven way through a mix of lectures, guided programming workshops, and discussion of topical research publications that students are expected to read before class.

The course belongs to the "Fachgebiet MLA (Machine Learning & Analytics)"

Learning Outcomes

After completing this module, and depending on students’ focus in the final project, they will be able to:

  • explain knowledge representation and argumentation formalisms used in AI&Law
  • explain the application of techniques from statistics, applied machine learning, and natural language processing to legal data
  • examine and critique experimental work and systems in legal data science/informatics
  • plan, implement, and evaluate a basic legal data science/informatics project

Grading

This module focuses on the interdisciplinary application of modern data science / artificial intelligence methods to a predominantly unstructured domain, and hence requires frequent and diverse interaction with the subject matter. TUM political science students will be invited to take the module to facilitate cross-disciplinary discussion.

Grading will be based on an individual project that students are required to complete and which will take place incrementally (with step-wise deadlines) starting at around the middle of the semester. The project components will include (1) a text annotation task (15%)*, (2) a 2-3 page written literature survey (15%)*, (3) an experiment in data analysis and model evaluation (middle level programming in Python using common libraries) to be submitted as code (20%)*, and (4) an 8-10 page final written report explaining and discussing the data, analytical methods, and results (50%)*. By default, all students will conduct the same project by themselves without collaborating with course colleagues. If students want to conduct a special project of their own design, they can propose it to the instructor in writing using a template. The instructor may then approve it if he deems it educationally comparable to the default project. In any case, the collective annotation task is a mandatory part of all course projects.

(*) Component grade percentages of the final grade 

Students are encouraged to submit questions about weekly reading assignments (i.e. topical publications) ahead of the session, which will be picked up during in-class discussions. Submitting a minimum number of quality reading questions will lead to a grade bonus of 0.3 at the end of the semester.
