Hector Joseph Levesque (born 1951)[1] is a Canadian academic and researcher in artificial intelligence.
His research concerns incorporating commonsense reasoning in intelligent systems and he initiated the Winograd Schemas Challenge.
After graduation, he accepted a position at the Fairchild Laboratory for Artificial Intelligence Research in Palo Alto, and then joined the faculty at the University of Toronto where he has remained since 1984.
On the representation side, he has worked on the formalization of a number of concepts pertaining to artificial and natural agents including belief, goals, intentions, ability, and the interaction between knowledge, perception and action.
The idea was written in his article "The Winograd Schemas Challenge" along with collaborators Ernest Davis from New York University and Leora Morgenstern from SAIC.
