Language Technology Lab

Welcome to the Language Technology Lab


The language technology lab carries out research in the field of Natural Language Processing. We mainly focus on two areas of specialization:

  • Educational NLP
    • Short answer scoring
    • Essay scoring
    • Vocabulary Acquisition
    • Spelling and grammar correction
  • Social Media Analysis
    • Robustness of tools
    • Domain adaption
    • Large-scale semantic processing

We are committed to reproducible and replicable research. Thus, we generally make all research software publicly available.




    GermEval 2017

    17.10.2017


    Together with the Language Technology Group (LT) from the University Hamburg, we have organized GermEval 2017 – Shared Task on Aspect-based Sentiment in Social Media Customer Feedback. In this shared task, we utilized one of the largest datasets among all so-far conducted shared tasks on Sentiment Analysis. The shared task was framed as aspect-based sentiment analysis with four sub tasks: Relevance, Document Sentiment, Aspect-based Sentiment and Opinion Target Extraction.

    The proceedings are available on the website. The task description can be found below:
