WiSe 2023/24

This course introduces several different theories of semantic annotation, including UD, semantic roles, frame semantics, AMR, and parallel meaning bank. The students will learn the theoretical backgrounds and the detailed annotation schemas, and gain some experience in annotating the real-life data, both manually and automatically.

To get BN, one should finish at least 60% of the homework successfully. To get AP, one should also pass a written exam.

Summary

In this seminar, we look into a variety of approaches to parsing that extend standard constituency parsers in different ways:
1. We will discuss approaches that are based on grammar formalisms that are able to generate structures that are beyond context-free grammars. Examples are LCFRS and TAG.
2. Related to this, we will discuss approaches that are able to describe discontinous constituents. These can be grammar-based (LCFRS) or transition based parsers with appropriate transitions such as gap or swap.
3. The course will also cover aspects of incremental, cognitively plausible approaches to constituency parsing.
4. Finally, if there is time, we will also have a look at unsupervised approaches to parsing, i.e., approaches that do not assume labeled training data (in contrast to 1.-3. above).

The course is based on material from the “Parsing beyond CFG” course in 2021/22 and has an extensive overlap with it. This means that student who took that course cannot take the present one in addition.
