Integrating Explicit Knowledge into Neural Network Approaches
The main topic of my current research. The underlying motivation is to integrate acquired knowledge about a specific task into state-of-the-art neural classification approaches. I mainly experimented on the task of hate speech detection, some of my publications point out early results.
Terminology Extraction
In the project "Textanalyse und Ontologieaufbau" (2014-2017) at the University of Stuttgart in cooperation with the Robert Bosch GmbH we investigated statistical methods to automatically extract domain-specific terminological expressions from text corpora. In the context of this research I wrote my Bachelor's and Master's thesis.
In cooperation with Tim van Niekerk from the Dictionary Unit for South African English (DSAE) we developed at the University of Hildesheim methods to extract uses of language-specific terms from South African English corpora (2017-2018). [Website]
