Abstract :
This paper presents a carefully described method for answering restricted natural language questions about elementary drawings. The algorithm produces as output a flow chart for a computer program which could then be used to infer the answer from a list structure representing the picture. The work described was performed while the author worked with Saul Amarel at the RCA Laboratories in Princeton, N.J. during the summer of 1965. The paper is well written, and its only major deficiency is that, in this rapidly moving field, a period of three and one-half years elapsed before it was published in the open literature.1
