    abstract = {Generative and evaluative approaches are two different ways 
of diagnosing students' input that have been realized in a number of 
intelligent tutoring systems. We describe how ActiveMath's exercise 
subsystem realizes both types of diagnosis and how it can combine them. 
A framework for distribution of diagnostic services is extending the ex- 
isting web-service approach to mathematical services with the notion of 
context. In addition to an appropriate diagnosis, a goal is the interop- 
erability of diagnosis services.},
