Steffen Eger

About me:

I am a Heisenberg grant recipient of the DFG, leading the Natural Language Learning Group (NLLG) at Bielefeld University, which is additionally funded by the BMBF through an interdisciplinary AI research group "Metrics4NLG". Previously, I was Substitute Professor at Bielefeld University, substituting Philipp Cimiano in the Semantic Computing Group and Independent Research Group Leader (IRGL) at TU Darmstadt. I obtained my PhD in economics on the topic of Social Learning/Opinion Dynamics.

My research interests include Natural Language Processing (NLP), Machine Learning, and applications in the Digital Humanities and Social Sciences. I am particularly interested in

evaluation metrics (for text generation) and text generation
applications in the Social Sciences and Digital Humanities, e.g., change of social biases over time, detection of social solidarity, poetry (generation/evaluation), cross-temporal approaches (language change), cross-linguality, argumentation

Earlier research interests included alignments, opinion dynamics (in a social science/economic context) as well as applications in math (such as integer compositions and limits of powers of matrices).

Teaching

I am currently teaching Deep Learning for NLP at Uni Bielefeld as well as Statistical Natural Language Processing and Ethical, Social, and Legal Aspects of Data Science.
I taught the course Deep Learning for Natural Language Processing (DL4NLP) at TU Darmstadt from 2016 to 2020. I taught Foundations of Language Technology (FOLT) from 2020 to 2021. I also held the seminars Deep Learning and Digital Humanities as well as Meta-Science and Evaluation. More information at my TU page.
