Jason was until last year an Associate Professor of Computational Linguistics at the University of Texas at Austin. As a professor, Jason worked on probabilistic models for categorization and syntax, with a particular emphasis on low-resource languages. He also focused on methods and applications for connecting linguistic objects to geography and time. He has been active in the creation and promotion of open source software for natural language processing: he is one of the co-creators of the Apache OpenNLP Toolkit, and he has contributed many others, including ScalaNLP, Junto, TextGrounder and OpenCCG. Jason received his Ph.D. from the University of Edinburgh in 2002, where his doctoral dissertation was awarded the 2003 Beth Dissertation Prize from the European Association for Logic, Language and Information. His main academic research interests include categorial grammars, parsing, semi-supervised learning, co-reference resolution and text geolocation.
