My research interests have included developing various knowledge representation frameworks and schemes and their associated reasoning mechanisms, and applying these processes together with machine learning to natural language, computer vision, animation, human-computer interaction, and information retrieval and information extraction.
My current research focus is argumentation in scholarly biomedical texts. Scientists and clinicians use argumentation to convince readers of their journal papers that the claims made in those papers should become part of the knowledge about biomedicine. Research in my lab is providing methods to have computers find these arguments in the natural language text of journal articles. Outcomes of this research will include indexing of scientific claims and evidence in the research literature, thus providing a method to navigate the scientific literature that adds a new dimension to the presently available keyword searching techniques.
