“The key to artificial intelligence has always been the representation.”

A chat bot also commonly known as the talk bot , IM Bot , Artificial Conversational Agent or the Interactive agent is referred to as the computer program or AI which directs and manages the chats via textual methods or the auditory methods.These programs are frequently designed to imitate that how the humans would acts as a conversational partner , thereby passing the turing test. Chat bots are more commonly used for the practical purposes in the dialog systems which includes the services of customers and the acquisition of the information.

Some of the chat bots uses the natural language processing , but many a times the simpler systems examine for the keywords within the inputs , then the reply is being pulled with the most matching keywords or the similar or same pattern of the words , fetched from the database.

The chat bots are created in the same pattern the mobile apps and web web applications are being created.To speed up the process of the chat bots , the designers can use the chat bot tools of design which are used for the immediate preview , collaboration of the team and the video export. The most principle aspect of the chat bot design is being focused around the testing of the user , and the user testing is performed following the same aspect of principle which guides the user testings of the graphical interfaces.

The procedure of building the chat bot is partitioned into the two main tasks : understanding the intent of the users and giving the correct and valuable answers.Understanding the input by the user in a free form of text , is involved in the first task and can use Natural Language Processing. Distinct approaches depending upon the type of response generated by the chat bot are involved into the second task.

The use of the chat bots are analyzed and monitors in order to pop-up the potential problems and the flaw, and is also used to improve the experience of the final users some useful insights have been provided.Chat-bots can be done on the platforms of the cloud based development and these cloud platforms provide the natural language processing , artificial intelligence and the back-end of the mobiles as an development for the chat bots.
