My research interests follow two diverse but related tracks:
- Computational Linguistics, in particular lexical semantics, where my doctoral studies originated, and where I was an instrumental part of two NSF research grants (1989-1994). In January of 1996, MIT Press published my (co-authored) definitive survey of the field, Electric Words: Dictionaries, Computers, and Meanings , and in the same month the Communications of the ACM published a survey article by the same authors; also in 1996, I co-edited a special theme issue of "IEEE Computer" devoted to Interactive Natural Language Processing which appeared in July; and
- Educational Multimedia, currently my primary interest, in particular:
- virtual role-playing environments where students are immersed in authentic game-play simulations that teach real-world strategies, and domain specific concepts and procedures; and
- integrated performance support systems where users are provided job-aid systems that support work through an analysis of process and expert help and advice for just-in-time training in the workplace.
