Jack Mostow Gives Invited Keynote Address in Barcelona
On July 22, Jack
Mostow gave an invited keynote address in Barcelona, Spain, at the 42nd
meeting of the Association for Computational Linguistics (http://www.acl2004.org/Invited%20talk-Mostow.htm).
The title was "If I Have a Hammer: Computational Linguistics in a Reading Tutor that Listens."
Abstract:
Project LISTENs Reading Tutor uses speech recognition to listen to children
read aloud, and helps them learn to read, as evidenced by rigorous
evaluations of pre- to posttest gains compared to various controls. In the
2003-2004 school year, children ages 5-14 used the Reading Tutor daily at
school on over 200 computers, logging over 50,000 sessions, 1.5 million
tutorial responses, and 10 million words.
This talk uses the Reading Tutor to illustrate the diverse roles that
computational linguistics can play in an intelligent tutor: ? A domain
model describes a skill to learn, such as mapping from spelling to
pronunciation. ? A production model predicts student behavior, such as
likely oral reading mistakes. ? A language model predicts likely word
sequences for a given task, such as oral reading. ? A student model
estimates a students skills, such as mastery of grapheme-to-phoneme
mappings. ? A pedagogical model guides tutorial decisions, such as
choosing words a student is ready to try. A recurring theme is the use of
big data to train such models automatically.
