RESEARCH INTERESTS

In my research work, I mainly focus on information retrieval, recommender systems, and natural language processing. In particular, techniques for the information extraction from unstructured data such as text and making information more accessible are of great interest for me. In my recent work I apply these techniques on content from the legal domain, e.g. laws, patents, case files. Moreover, I explore how recommender systems can assist users in finding relevant information to cope with today’s information overload. Due to the large amounts of available data, all my work requires the use of scalable and distributed computing. Generally speaking, all topics that are somehow related to the following fields can be considered as my research interest:

• Recommender Systems
• Natural Language Processing
• Large Language Models
• Text Mining
• Applied Machine Learning
• Scalable Data Processing (“Big Data”)
• Legal Tech

I am also affiliated with the German Research Center for Artificial Intelligence (DFKI). Aside from my research activities, I founded the non-profit initiative Open Legal Data that provides free access to legal documents such as law text and court decisions.
