Research

Interests:

• AI and computational linguistics:
  • Discourse and dialogue planning, shallow (but not superficial) text generation, mixed-initiative and multi-modal systems.
  • Knowledge representation for tutoring and causal reasoning.
  • All kinds of declarative formalisms (logic programming, constraint-based programming, etc.).
  • Dialogue annotation and analysis.
    
    
• Linguistics:
  • Romance linguistics.
  • Semitic linguistics.

Current research projects:

URAP information (undergraduate research projects)

Previous research projects:

• Circle

  Tutorial planning and text generation for the Atlas system. Atlas is an integrated planning and execution system that will allow natural language dialogues to become an integral part of an intelligent tutoring system. Atlas is a product of Circle, the Center for Interdisciplinary Research on Constructive Learning Environments. Circle is a National Science Foundation-funded resarch center drawing personnel from the University of Pittsburgh and from Carnegie-Mellon University. Its goal is to develop a new generation of intelligent tutoring systems which foster the same kind of learning as one-on-one human tutoring. Tutoring systems involved with Circle include Andes and the Advanced Computer Tutoring Project at CMU.

• Circsim-Tutor

  CIRCSIM-Tutor is an intelligent tutoring system that helps medical students understand blood pressure regulation. The latest version (v. 3) generates dialogues with sophisticated strategies for tutoring and dialogue control based on an empirical analysis of transcripts of human tutoring sessions. This reseach was supported by the Office of Naval Research.

Other miscellaneous projects:

Getting Microsoft out of my life.
