Johann Petrak

I am a research fellow at the University of Sheffield and a member of the Natural Language Processing Group of the Computer Science Department. I am working on large-scale multilingual entity recognition and disambiguation and I am part of the team that develops the GATE NLP framework and have also developed and contributed to a number of GATE plugins and other GATE related software. I am generally interested in machine learning, natural language processing and knowledge representation / ontologies.

Prior to joining the University of Sheffield, I was a researcher at the Austrian Research Institute for Artificial Intelligence (OFAI).

For a list of publication see Google Scholar or my Sheffield University Page.

Software

I am an enthusiastic developer and supporter of open source software and have contributed to the development of the GATE NLP framework and a number of other projects.
