The Authoring Assistant

In some domains, including those requiring natural language understanding, we cannot build a system that can complete the entire task. One way to deal with such cases is to encode the result of understanding the problem description along with traces of the process used to understand that description. This places the natural language understanding portion of the system in the authoring system, as opposed to the run-time system (the one used by the student). This solution, however, puts a burden on the author, who must now verify that the problem encoding reflects the desired understanding. We describe the Authoring Assistant, a component of the pSAT system  for authoring problems for the PAT Algebra tutor  which addresses these issues.
