Commonsense knowledge (also called common sense) is something that people know, or can understand easily. It's the knowledge most of us use to make decisions in our day-to-day lives. For example, common sense might tell you that if you walk outside during a thunderstorm, you will get wet. Artificial intelligence (AI) is a type of computer technology that can "learn" to understand and use common sense knowledge. AI can be taught to recognize patterns, use logic, and make decisions based on what it has learned. AI can be used to automate tasks, answer questions, and even analyze large amounts of data to provide insights. By using AI to understand common sense knowledge, computers can become smarter and more useful in our daily lives.
