(September 21, 2015) The
Allen Institute for Artificial Intelligence (AI2) and University of Washington
researchers have created an artificial intelligence (AI) system that can solve
SAT geometry questions as well as the average American 11th-grade student, a
breakthrough in AI research.
This system, called GeoS, uses a combination of computer
vision to interpret diagrams, natural language processing to read and
understand text and a geometric solver to achieve 49 percent accuracy on
official SAT test questions. If these results were extrapolated to the entire
Math SAT test, the computer roughly achieved an SAT score of 500 (out of 800),
the average test score for 2015.

A paper outlining the research, “Solving Geometry Problems:
Combining Text and Diagram Interpretation,” was a joint effort between the UW
Computer Science & Engineering department and AI2.
These results, presented at the 2015 Conference on Empirical
Methods in Natural Language Processing (EMNLP) in Lisbon, Portugal, were
achieved by GeoS solving unaltered SAT questions that it had never seen before and
that required an understanding of:
