  I have also begun a project (with Dan Huttenlocher) in developing corporate memory through <A HREF="http://dri.cornell.edu/pub/davis/annotation.html">shared annotation</A> of structured documents.  This project investigates how people can share information by reading and writing annotations in electronic documents shared by the group.  An initial prototype implementation is being used by Cornell class CS212.  Here, the shared documents are problem sets and course notes, and a nnotations might be requests for clarifications by students, technical questions, or corrections made by staff.  The question is whether this will be a useful means for students to obtain answers, whether students will find each other's questions a useful source for learning, whether students will often be able to answer each other's questions (correctly), and whether the course staff will find this a useful means for feedback in improving the course.  So far, the evidence is that they do.  <P>
