. 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. On the reasoning side, his research mainly concerns how automated reasoning can be kept computationally tractable, including the use of greedy local search methods.

In 2004, one of the 1984 papers was awarded the Classic Paper award of the AAAI, and the other was given an honourable mention. In 2006, a paper written in 1990 was given the inaugural Influential Paper Award by the International Foundation of Autonomous Agents and Multi-Agent Systems.
In 2011, Hector Levesque proposed a new way to test artificial intelligence called
Winograd Schemas Challenge as a possible alternative of the
Turing test
The Turing test, originally called the imitation game by Alan Turing in 1950, is a test of a machine's ability to exhibit intelligent behaviour equivalent to, or indistinguishable from, that of a human. Turing proposed that a human evaluato ...
