ANTswers chatlogs are reviewed on an on going basis and updates are made to the code regularly. If ANTswers can't answer a question or answers it incorrectly the botmaster reviews the code, makes changes, and then uploads it to the system. ANTswers has been a work in progress for the past 7 years and as time goes on the chatbot get's better and better at answering the questions it is asked.
ANTswers works on pattern matching. You ask a question such as: I want information on Anteaters. Program-O then searches through all of the code and returns the answer with the highest % match. Sometimes this means that if there isn't code that matches really well, ANTswers will return a strange response. This is especially true if you ask a long complicated question.
Sometimes there isn't a pattern that matches your question in the chatbot code and you will sometimes get a response from ANTswers for you to rephrase your question. If you ask the same question over and over you will not get a different answer. Instead slightly change your question to see if you can get a response.
