As a researcher, I am primarily interested in Artificial Intelligence and its applications. I have worked in many areas of AI: planning, knowledge representation and reasoning, image processing, natural language processing, document classification, artificial neural networks, and the use of massively parallel machines to solve AI problems.† I am also interested in the use of AI techniques to build better user interfaces and context-aware systems.
Currently, I am working on Scone, a practical Knowledge Base System (KBS) that can represent a large body of real-world knowledge and that can efficiently perform the kinds of search and inference that seem so effortless for us humans.† This work is based in part on the NETL system that I developed for my Ph.D. thesis in the late 1970s, but the Scone system is designed to run on standard workstations and servers rather than on special parallel hardware.
My research group has worked on a number of applications of Scone, with a special focus on using Scone to support knowledge-based natural language understanding and generation.† I believe that Scone-like knowledge base systems will be important tools in the future, perhaps used in even more ways than database systems are used today.†
I am also working on some ideas for new learning architectures for deep-learning networks, inspired in part by the Cascade Correlation architecture that I developed in 1990 with Chris Lebiere.
I am a Fellow of the Association for the Advancement of Artificial Intelligence (AAAI) and a Top Writer on the Quora website.
I was one of the core developers of the Common Lisp language, and my research group developed the CMU Common Lisp implementation which formed the basis for many commercial Common Lisp systems, and now is maintained as open-source software, along with a split-off version, Steel Bank Common Lisp.
In 1982, I proposed the use of†† :-)†† and† :-(†† in posts and Email messages.† These are generally regarded as the first internet emoticons, and the text-only ancestors of todayís graphical emojis.
