Hi there, I'm Thiemo.

Picture of Thiemo

I'm a PhD student at the Institute of Information Systems at the University of St.Gallen (CH). Currently, I am a research collaborator at the Human-Computer Interaction Institute at Carnegie Mellon University.

I strive to conduct interdisciplinary research in the fields of Information Systems, Computer Linguistics, and Human-Computer-Interaction to increase learning success and education across all domains. To do so, I use techniques from Artificial Intelligence such as Natural Language Processing, Transfer and Deep Learning to build AI-powered education tools such as Intelligent-Tutoring-Systems, Conversational Agents, and intelligent writing support systems. You can find information on my work on AI for Education

As part of a research team, we have developed an adaptive argumentation writing support system which helps individuals to develop better writing and reasoning skills (Link to CHI 2020 paper). Also, we have built an intelligent conversational agent that provides students with adaptive and individual argumentation tutoring while writing persuasive essays independent of an instructor, time or location (Link to CHI 2021 paper). Recently, we design an empathy writitng support tool by modeling the cogntive and emotional empahty structures in student-written texts (Link to ACL 2021 paper).

I believe in the power of collaboration for building better AI-based systems. If you are interested in my work, please contact me via LinkedIn

Corpora and Data Sets

In order to build HCI innovations, I collected, annotated and scientifically evaluated different corpora and data sets to train novel machine learning or deep learning models. Here is an overview of my work:

  • German User-Generated Repair Instruction Corpus: 3,157 user-generated posts, with 682 tagged “Instruction” and 2,475 tagged “NoInstruction”, representing different characteristics of the platform motor-talk. Access
  • Argumentation Annotated Student Peer Reviews Corpus: 1000 persuasive student peer reviews about business model feedbacks annotated for their argumentative components and argumentative relations. Access
  • Argumentation Annotated Student Business Model Pitch Corpus: 200 persuasive business model pitches annotated for argumentative components, argumentative quality score and argumentative relations.
  • Cognitive and Emotional Empathy Annotated Student Peer Reviews Corpus: : 500 student peer revies about business model feedbacks annotated for their cognitive and emotional empathy level according to key constructs. Access
