ON THE REPRESENTATION OF LIMITED INFORMATION BY MEANS OF r,•CTURES, TREES, AND ENGLISH-LIKE SENTENCES

Most of the work described here was done in the sunmmer of 1965 as part of our conLinuing research in the general area of machine problem solving. In the fall of 1965, a (limited distribution) report covering this work was issued at RCA Laboratories and at the Mental Health Research Institute of the University of Michigan. Plans to revise this report and to combine it with subsequent results of our work on representations in question-answering systems have delayed its wider distribution. However, since the work described in the report is relevant to much current research on granhic languages and question-answering, we have decided to extend its availability to the technical community in its present form, and to issue it as a technical report
