Research Topics

I'm a computational linguist with a research focus on natural language processing methods for web marketing and social media monitoring. More precisely, I am working on sentiment analysis and opinion mining. Lately I did fine-grained classification of product reviews, now heading towards getting positions from political texts. A good reason why it is important to understand the content of product reviews while analyzing them can be found here (btw, this guy has a strong opinion on computational linguistics ;) ).
However, I am also interested in applications of stylometry, like predicting age, gender or personality of an author from his texts.
Besides NLP, I like the CCC, lock picking and Club Mate!
