I just completed my second 4-year term as department chair, and I'm returning now to the best job in the world – university professor – with its largely uninterrupted focus on research and teaching.

Research

In setting a new research direction, I have decided to focus on machine reading. This technology holds tremendous potential for capturing knowledge for automated inference, question answering, explanation generation, and other AI capabilities that interest me.
Most machine reading projects have focused on macro-reading, i.e. skimming many documents to extract repeated facts or commonly expressed sentiments. I would like to focus primarily on micro-reading, which aims to extract considerable content from each individual document. I will assume that methods for natural-language processing will continue to improve, which will make micro-reading increasingly effective, and I will focus on issues like these:
  • goal-directed navigation of a corpus of documents
  • methods for (dis-)confirming information derived from text
  • extracting information from diagrams and tables
  • integrating extracted information into a knowledge base
  • ways that macro-reading might inform micro-reading, and vice-versa

Teaching

I will not be teaching Fall 2017. In Spring 2018, I will teach CS 302: Computer Fluency.

News

I am co-organizing a workshop on Machine Reading, with long-time friends and colleagues, Peter Clark and Ken Barker. It will be co-located with the 2017 K-Cap conference, which will be held in Austin on December 4-6.
