Enhanced and Deep Universal Dependencies for Many Languages

Many linguistic theories and annotation frameworks contain a deep-syntactic and/or semantic layer. While many of these frameworks have been applied to more than one language, none of them is anywhere near the number of languages that are covered in Universal Dependencies (UD). In my talk, I will first discuss Enhanced Universal Dependencies (EUD), a set of semantically-oriented enhancements that have been proposed within the framework of Universal Dependencies (but which are still available only for a small number of languages). I will also present some preliminary observations from the current shared task on parsing into EUD (https://universaldependencies.org/iwpt20/). In the second part, I will present some additional enhancements, called Deep UD, which extend beyond the official UD guidelines. I will focus on two aspects: how can these enhancements be useful for natural language understanding, and to what extent can they be obtained semi-automatically from the surface annotation for many typologically different languages.

Due to the COVID-19 crisis, the talk will not take place physically at ÚFAL. Instead, it will be broadcast remotely as a Zoom meeting at https://matfyz.zoom.us/j/320747092. The meeting will be recorded and made available online.
