Methodology and fundamentals: My methodological work includes the analysis and improvement of established methods, e.g. Delta measures for authorship attribution, as well as the development of novel methods such as the generalized cooccurrence model. I am also involved in the creation of fundamental linguistic resources such as a part-of-speech tagset for Albanian.
Actual implementation: My work has a strong practical component and I am (co-)developer of several tools and web interfaces, some of which represent the state-of-the art in their respective fields.
Evaluation: As part of my research, I assess the performance of methods and tools in realistic settings, both to find out which established methods and tools work best and to evaluate my own work.
I have a strong interest in natural language processing (NLP). So far, I have been active in the following areas: tokenization, part-of-speech tagging, unsupervised dependency parsing, sentiment analysis, and semantic similarity. I am (co-)developer of two state-of-the-art tools (tokenizer and part-of-speech tagger) for German web and social media texts.
