The team is from the University of Illinois at Chicago and an AI research group in Hungary. The AI system which they used is ConceptNet, an open-source project run by the MIT Common Sense Computing Initiative. Results: It scored a WPPSI-III VIQ that is average for a four-year-old child, but below average for 5 to 7 year-olds.
"We found that the WPPSI-III VIQ psychometric test gives a WPPSI-III VIQ to ConceptNet 4 that is equivalent to that of an average four-year old. The performance of the system fell when compared to older children, and it compared poorly to seven year olds."
They wrote, "In the work reported here, we used the March 2012 joint release of ConceptNet 4 implemented as the Python module conceptnet and AnalogySpace implemented as the Python module divisi2.3. In this paper ‘ConceptNet’ refers to this combination of AnalogySpace and ConceptNet 4 unless explicitly stated otherwise."
The title of their paper is "Measuring an Artificial Intelligence System’s Performance on a Verbal IQ Test For Young Children," and the authors are Stellan Ohlsson, Robert Sloan, György Turán and Aaron Urasky. They represent academic disciplines of statistics, computer science and psychology.
