I am a postdoctoral researcher in natural language processing, working at the Language Bank at the University of Gothenburg. My research focuses on designing computer software that understands information in written text by analyzing the grammar of the text. Examples of such computer tools include:
Apart from the practical applications, there are also a number of theoretically interesting questions:
