Visual Reasoning with Graphs.

摘要

Understanding diagrams is an important part of human cognition. Computer programs need to understand and reason using diagrams to communicate effectively with people. This paper explains how line graphs can be interpreted in a domain independent manner. We present a computer program called SKETCHY that reasons about physical phenomena visually by using line graphs. SKETCHY can interpret graphs to recover functional relationships, answer comparative analysis questions and generate qualitative descriptions using geometric models.
