ALICE is a computer program designed to create conversational agents, often referred to as chatbots. It uses a set of predefined rules and patterns to generate responses based on user input. ALICE is known for its ability to simulate human-like conversations, making it a popular tool for developers interested in artificial intelligence and natural language processing. Developed by Richard Wallace in the late 1990s, ALICE stands for Artificial Linguistic Internet Computer Entity. The program won the Loebner Prize, an annual competition in artificial intelligence, multiple times. Its underlying technology has influenced other chatbot frameworks and contributed to advancements in the field of AI and machine learning.
