University of Illinois at Chicago (UIC) researchers have IQ-tested the ConceptNet4, considered one of the best available artificial intelligence systems, and found that it is about as smart as the average four-year-old.

The researchers tested the ConceptNet4 system on verbal portions of the Wechsler Preschool and Primary Scale of Intelligence Test, a standard IQ assessment for young children. They found that ConceptNet4 has the average IQ of a young child, although its scores were very uneven across different portions of the test, which is unlike most children.

"If a child had scores that varied this much, it might be a symptom that something was wrong," says UIC professor Robert Sloan.

The researchers found that ConceptNet4 did very well on the vocabulary and similarities portions of the test, but very poorly on the comprehension portion. Sloan says one of the hardest problems in building an artificial intelligence is devising a computer program that can make sound and prudent judgments based on a simple perception of the situation or facts, which he notes is the dictionary definition of common sense.
