Our research topics are centered around large unstructered datasets, mostly textual data. We are working at the interface of the fields of information retrieval (IR) and natural language processing (NLP). We do research on topics like:

  • Supporting humans searching the web (query understanding, comparative questions, user simulation and abstractive snippets)
  • Analyzing large web crawls (near-duplicates and ad-hoc search)
  • Identifying good arguments (argument mining and argument search)
  • Analyzing and supporting human writing processes (authorship and paraphrasing)
  • Understanding how we will (soon) communicate with many tools (conversational interfaces)
