Direct memory access parsing in the Creanimate biology tutor

Computer tutors that engage in dialog with students require effective parsing technology to understand the intentions of the students. A report is given on an implementation of a direct memory access parser (DMAP) for a computer based biology tutor (Creanimate). The author begins by describing the Creanimate system and giving an overview of direct memory access parser. He then describes the parser developed for Creanimate, DMAP-C, and the extensions and enhancements compared to previous DMAP parsers. Finally, he gives a qualitative evaluation of the effectiveness of the DMAP-C parser.<>
