Chatterbot

A chatterbot is a computer program designed to simulate an intelligent conversation with one or more human users via auditory or textual methods. Though many appear to be intelligently interpreting the human input prior to providing a response, most chatterbots simply scan for keywords within the input and pull a reply with the most matching keywords or the most similar wording pattern from a local database. Like any person, chatterbots seem to have a sort of personality which is expressed by their answers. The top chatterbots are Elbot, Talk-bot, Yabberwacky, Eugene, Alice, and Alan. A chatterbot is a conversation simulator done as a computer program which gives the appearance of conversing with a user in natural language.
