About Catherine

I am a philosopher trained in the analytic tradition who also identifies as a classical American pragmatist, with a particular passion for the thought of Charles Peirce. Peirce's elegant observation, "Symbols grow", sums up for me a lot of what is original and exciting in his work.

I also have strong research interests in IT. In 2012 I was awarded a grant from the New Zealand Marsden Fund with Professor Ian Witten, Department of Computer Science, University of Waikato. The project is running for 3 years and is titled, “A Self-correcting Knowledge base for Large-scale Knowledge Engineering.” With the help of Samuel Sarjant, our postdoc, we are building a giant ontology, with question-and answer functionality, entirely automatically from concepts mined from Wikipedia and other sources freely available on the Web.
