Semantic Theory is a core course of the Master of Science programme in Language Science and Technology (LST), taught at the department of Language Science and Technology at Saarland University.

Content

This course focuses on the theoretical study of natural language meaning, with explicit links to practical applications. The first part of the course introduces sentence-level (Montague) semantics: starting out from first-order predicate logic and moving to (typed) lambda calculus. In the second part of the course, we zoom in to the level of lexical semantics, in particular focusing on verbs (event semantics) and quantified noun phrases (generalized quantifiers). We then move to discourse-level semantics: based on the framework of Discourse Representation Theory, we study discourse-level phenomena such as anaphora and presupposition. The final part of the courses is dedicated to recent advances in semantic theory: we discuss Distributional Formal Semantics, a formalism that extends formal semantics with a distributional component, providing compositional and probabilistic meaning representations that are also suitable for use in contemporary deep learning approaches.

Time: Tuesdays and Wednesdays, 10:15-11:45
Place:: Room -1.05 (C7.2, basement)
Start date: 13.04.2022 (Note: the first lecture will take place online, through MS Teams)

Format and Requirements:

  • The course will be taught in person (not hybrid), with digital support through MS Teams.
  • Exercise sheets will be made available after each lecture, and are due before the next lecture slot. During the exercise sessions, we will discuss questions about open exercises, and solutions to completed exercises in a Q&A style manner;
  • There will be an exam at the end of the semester (20.07.2022). Your grade for this exam will be your grade for the course;
  • To be admitted to the final exam, you may skip or fail at most one weekly exercise;
  • We strongly encourage active participation during all lectures and exercise sessions.

Prerequisites: Familiarity with first-order predicate logic. Specifically, we expect you to be familiar with the content described in the first two sections of this chapter: Logic in Action, Chapter 4 (Sections 4.1 & 4.2).

Registration: To register for this course, please send us an email and we will invite you to the MS Teams.

Literature

We will provide weekly additional reading material for each topic, which will be updated throughout the semester. Some important online resources:

Schedule

Note that this is a preliminary schedule, which may change during the course of the semester. Tuesday and Wednesday sessions will be flexibly organized as lecture and/or exercise sessions, so we encourage participants to attend all sessions. All course materials (slides, reading material, exercises) will be made available through MS Teams.
