Chatterbot review 4

A chat bot is also well known as chatterbot. A computer program is design in such a way that the program can continue textual or auditory conversation with human. This technology is mainly use to fool the human and make him feel that he is having conversation with human. This is the so called chat bot. But the recent use of chat bot is different, it is more useful. Nowadays, this technology is use for technical help and support.

It is also use for customer service as conversational agents. You may have heard about processing natural language system. But there is difference between this system and chat bot. The algorithm used in chat bot is much simpler compared to the processing natural language system. Many chat bots show their intelligence while responding textual conversation and some of them have almost same response as if human is responding. Scientists are working for artificial intelligence for many years. Michael Mauldin first introduced the term chat bot in 1994. (His creation was called Verbot, Julia.) He created Verbot, Julia.

A famous article about artificial intelligence is “Computing Machinery and Intelligence” written by Alan Turing. He created a test criterion, named as Turing test. Turing Test is use to determine the level of intelligence of computer programs. He had shown that a human judge could not able to find out the computer program alone from a conversation between human and computer program.

You may have heard about ELIZA (capital letter is used to express but there is no elaboration). It was first developed by Joseph Weizenbaum in 1966. Weuzenbaum designed ELIZA to provide "parody of the responses of a non-directional psychotherapist in an initial psychiatric interview" in his words. ELIZA was based on a principle developed by the psychiatrist Carl Rogers’ client centered therapy. ELIZA was actually used as a role of real therapist.
ELIZA (1966) and PARRY (1972) were historical chatter box. A.L.I.C.E, D.U.D.E AND Jabberwacky are the recent popular chat bot. (Simulate type of conversations were in ELIZA and PARRY, where recent programs also have some features like web search, games and other things.)

ELIZA and PARRY were used to simulate conversations while recent chat bot now have features like web search, games and other things. Natural language processing system is mainly connected to artificial intelligence. A.L.I.C.E. was based on simple technique of pattern making. The same technique was used early in case of ELIZA. Logic approval, reasoning ability and sapience are required for strong AI (artificial intelligence). Jabberwacky is quite fast. It has learned context based instructions and new responses.

The latest chat bots was based on real time evolutionary algorithms. These were optimized with ability that can communicate with each of the conversation held. For example Kyle, the winner of leodis al award 2009. Nowadays the research on AI has no general purposes. But practical aspect was focused in software development organizations. Information retrieval is a reason.
There are different uses of chatter bot. As virtual assistant chatter bot is an effective and worthy solution. The bank services, mobile phone operator services also other call center services can be handled by chatter bot. Famous online portal services like PayPal and eBay used virtual agents on multiple purposes. AI chatter bots can provide restless, 100% correct services. Another type of chatter bot is malicious bot. These are used to fill frequently the chat rooms, spam and trash, advertising. Commonly used messenger services are places to find chat bot. You may have known about the chat bot competitions. The two popular chat bot competitions are The Chatter Box Challenge and Leobner prize.
