AIML (Artificial Intelligence Markup Language) is an XML-based language to store segments of knowledge inside XML tags. AIML files help us store knowledge in a structured way so that we can easily access it whenever required.

AIML was developed by Richard Wallace and the free software community worldwide between 1995 and 2002. You may have heard about chatter bots such as Artificial Linguistic Internet Computer Entity (A.L.I.C.E.) and ELIZA. AIML is the base of these chatter bots. The dataset of the A.L.I.C.E. chatter bot is available under the GNU GPL license, and there are open source AIML interpreters available in C++, Python, Java, and Ruby. We can use these interpreters to feed our input to the knowledge base and retrieve the best possible reply from it.
