Simone Paolo Ponzetto

I joined the Data and Web Science Group in February 2013 as Juniorprofessor and hold since February 2016 the Chair of Information Systems III (Enterprise Data Analysis) as full professor (W3) at the University of Mannheim, where I lead the Natural Language Processing and Information Retrieval group.

Main research interests:
  • Knowledge acquisition: unsupervised and weakly-supervised information extraction; multilingual ontology learning and relation discovery from large text collections and collaboratively constructed resources; temporal information extraction; matching and fusion of heterogeneous knowledge bases (e.g., structured vs. unstructured).

  • Natural Language Processing: lexical semantics (entity linking and ranking, word sense disambiguation and induction); knowledge-based and distributional approaches to semantic similarity; discourse semantics and pragmatics (coreference resolution, discourse coherence, automatic document summarization).

  • Text mining applications: semantic document modeling and search; content-based recommender systems; automatic analysis of political and government data; sentiment analysis and opinion mining; integration of natural language and vision processing; Natural Language Processing for historical texts.

joint JOIN-T team wins SemEval TExEval-2

A system developed as part of a collaboration between the NLP group of DWS and the Language Technology group of TU Darmstadt has been ranked first in an upcoming SemEval challenge on Taxonomy Extraction Evaluation (TExEval-2).

The results of the challenge can be found here. SemEval is the premier evaluation forum the computational semantics community. This work is part of an ongoing DFG-project (JOIN-T) collaboration between the two groups.
