A.L.I.C.E. (Artificial Linguistic Internet Computer Entity) is a natural language processing chatbot created by Richard Wallace in the mid-1990s. It uses a set of rules and patterns to understand and respond to user inputs, making it one of the earliest examples of conversational AI. A.L.I.C.E. won the Loebner Prize multiple times, showcasing its ability to engage in human-like conversations. The chatbot operates on a framework called AIML (Artificial Intelligence Markup Language), which allows developers to create conversational agents. A.L.I.C.E. has influenced many other chatbots and AI systems, including Siri, Alexa, and Google Assistant, by demonstrating the potential of AI in human-computer interaction.
