Carl Gutwin

Carl Gutwin is a Canadian computer scientist, professor and the director of the Human–computer interaction (HCI) Lab at the University of Saskatchewan. He is also a co-theme leader in the SurfNet research network and was a past holder of a Canada Research Chair in Next-Generation Groupware. Gutwin is known for his contributions in HCI ranging from the technical aspects of systems architectures, to the design and implementation of interaction techniques, and to social theory as applied to design. Gutwin was papers co-chair at CHI 2011 and was a conference co-chair of Computer Supported Cooperative Work 2010.

Education Gutwin has undergraduate degrees in computer science and in English literature. He received his PhD in 1997 from the University of Calgary, where he worked and developed the idea of workspace awareness as a design factor for distributed groupware systems. Gutwin developed a key phrase extraction algorithm along with Ian Witten, Gordon Paynter, Eibe Frank, and Craig Nevill-Manning called KEA. Key phrases are important to a document as they provide a brief summary of a document's content and as document collections such as digital libraries become larger, the value of such summary information increases. The goal of the algorithm is to help alleviate the tedious process of assigning key phrases manually. The algorithm uses machine learning, lexical methods, and calculates feature values for each candidate to predict which candidates are good key phrases.
