Artificial intelligence AI. Artificial intelligence is a software or system that imitates the intellectual work that the human brain is doing with a computer. Specifically, it refers to a computer program that understands natural languages used by human beings, performs logical reasoning, learns from experience, and the like. Examples of applications of artificial intelligence include expert systems that imitate experts’ problem solving techniques, machine translation systems that automatically translate, image understanding systems that understand the meaning of images and sounds, and speech understanding systems. Lisp and Prolog are known as programming languages suitable for describing artificial intelligence.
