Our research projects and some student's term projects have lead to several NLP resources that we are making available.
- The Potsdam Commentary Corpus (PCC): A corpus of multi-level annotated German newspaper commentaries
- arg-microtexts: A German English parallel corpus of 112 short argumentative texts annotated with argumentation structures
- The Potsdam Twitter Sentiment Corpus (PotTS): A collection of 8,000 German tweets manually annotated with fine-grained sentiment relations
