Artificial intelligent system is a system that is made to "learn" during its existence. In other words, it learns to respond to situations in order to reach its objective. Intelligent systems are designed to automate the decision-making process and to assist and enhance the human decision-making process. The business world has recognized the need for intelligent information systems in the effective functioning of business. Expert systems, neural networks and intelligent agents are regaining their importance in business applications. Fuzzy logic, pattern recognition and speech recognition have gained exemplary importance as business applications, where they not only need to deal with uncertainty but also to provide a highly secure system. Artificial intelligent systems are gaining momentum because they are designed to emulate human reasoning. They have now gradually branched out with nonlinear approaches to solve the problems that often arise in business. This is where these applications gain an edge over the conventional applications whose flow is linear. Some of the benefits of intelligent applications are lower costs, optimal decision-making, and increased productivity and efficiency. This paper discusses the applications of artificial intelligence in the marketing function of business. Business professionals need an understanding of artificial intelligence applications, especially the expert systems and neural networks that are being used extensively by large companies.

Artificial Intelligence (AI) is the study of creating machines that have the ability to simulate human intelligence. The aim of AI is to develop computers that can think, learn or understand from experience, use reasoning and apply knowledge to solve problems.

An interesting test for determining whether a computer exhibits intelligent behavior was proposed by Alan Turing, a British AI pioneer in 1950. According to the Turing test, a computer could be considered as intelligent only when a human interviewer, conversing with both an unseen human being and an unseen computer cannot differentiate one from the other.
