Information for students, faculty and staff regarding COVID-19. (Updated: 26 May 2020)
I have long worked at the boundary between AI and relational databases, in particular within cooperative query answering, explanation, information integration and natural language interfaces. I also coordinated the EU project spacebook that involved both spatial databases and speech-based interfaces.
Relational databases have always impressed me because they have proven their usefulness in the real world and, at the same time, are rooted in logic. And if one takes full database query languages (e.g. those performing counts and other aggregation operations), then it is not merely first-order logic, but higher-order logic. My current research focusses on using logical properties of query languages to facilitate the construction and learning of natural language interfaces to databases.
