Dominik Schlechtweg
I did my PhD at the IMS (University of Stuttgart) working together with Sabine Schulte im Walde on automatic detection of lexical semantic change. I held a PhD scholarship from Konrad Adenauer Foundation. After my PhD I did a research internship with Katrin Erk at the University of Texas, Austin. Since February 2022, I am an independent research group leader at the IMS (University of Stuttgart) working in the 6-year research program Change is Key!. I am also the leader of the PhiTag and DURel projects where we develop open source text annotation platforms.

Interests
- optimization of human text data annotation processes (see PhiTag and DURel)
- automation of lexicographic processes
- application of lexical semantic computational models
- statistical modeling of word meaning
Projects
- PhiTag: An open-source text annotation platform.

- DURel Tool: An annotation tool for semantic proximity between use pairs.
[slides] [poster] [blog] [link]
- Word Usage Graphs represent usages of a word as nodes in a graph which are connected by weighted edges representing (human-annotated) semantic proximity.

- Logic in Linguistics: I am developing ILIAS-based interactive learning materials for logic in linguistics including learning modules, pools of questions and corresponding paper handouts. Topics include Arguments and argument schemata, Sets, relations and functions, Propositional logic, Predicate logic and Theory of types with lambda operator. Feel free to approach me if you want to use them outside of ILIAS-Stuttgart. All materials are in German.
