BIB-VERSION:: CS-TR-v2.0 ID:: STAN//CS-TR-82-909 ENTRY:: June 01, 1995 ORGANIZATION:: Stanford University, Department of Computer Science TITLE:: Plan recognition strategies in student modeling: prediction and description TYPE:: Technical Report AUTHOR:: London, Bob AUTHOR:: Clancey, William J. DATE:: May 1982 PAGES:: 12 ABSTRACT:: This paper describes the student modeler of the GUIDON2 tutor, which understands plans by a dual search strategy. It first produces multiple predictions of student behavior by a model-driven simulation of the expert. Focused, data-driven searches then explain incongruities. By supplementing each other, these methods lead to an efficient and robust plan understander for a complex domain. NOTES:: [Adminitrivia V1/Prg/19950601] END:: STAN//CS-TR-82-909
