Research Interests
  • Metaphor detection
  • Sentiment analysis
  • Subjectivity detection
  • Hedge detection
  • Deception detection

My PhD topic concerns the detection of metaphors in political contexts. For this I have created a metaphor dataset of roughly 500 German online news-headlines, annotated by non-experts. Feel free to check out (or even participate in) the annotation process at http://nlp.h-its.org/annotation/index.php .

Previous research concerned deception detection - this work is part of the JUMAS project (http://www.jumasproject.eu/), a European project funded by the ICT programme within the 7th Framework Programme for Research and Development activities of the European Commisson; I also worked on hedge detection and was the first one to work on weasel-word detection, taking advantage of corresponding maintenance tags in Wikipedia (http://en.wikipedia.org/wiki/Template:Weasel).

Other topics I am interested in are sentiment analysis and subjectivity detection, as well as idiom detection, of course, as it is so close to my actual research topic.

About Me

Before coming to HITS (or "EML Research", as it was called back then), I completed my BA in Cognitive Science at the Universität Osnabrück. There I got to know the fascinating field of computational linguistics, which I then pursued to study at Universitet Stockholm (MA degree in CL) under supervision of Dr. Martin Volk.
I spent some time at Linköping's Universitet within the Erasmus program, and I studied one semester in Heidelberg as a "Swedish exchange student" (it's a long story).

Degrees

  • Master of Arts (Filosofi Magisterexamen)  in General Linguistics with Focus on Computational linguistics
    • Thesis 1 (C-Uppsats): "Cross-lingual Annotation of Semantic Frames in Treebanks"
    • Thesis 2(D-Uppsats): "A Bootstrapping Method for Learning German Subjective Nouns"
  • Bachelor of Science in Cognitive Science 
    • Thesis: "Object Properties and Telicity"

 

Personal Interests

  • During freetime, I am either buisy making any kind of noise or populating the world with little monsters. Seriously, they are an endangered species.
