A major PETTT effort is a collaboration with a senior
researcher in the database group at Microsoft research, senior faculty in the
Information School, and UW graduate students to explore a knowledge
management system
in which (1) educational content is organized into a multimedia XML database by author-friendly
templates, (2) the learner accesses the information using natural language
questions which are processed into a resource description (RDF) framework and matched against
authoritative content, and (3) the efficacy of the program is rigorously
evaluated.
