Knowledge Engineering is the process of designing, building, and managing systems that enable computers to mimic human expertise in specific domains. It involves gathering, organizing, and structuring knowledge from human experts or existing sources, transforming it into a form that can be used by computer systems. This includes creating knowledge bases, designing inference mechanisms, and ensuring that the system can solve real-world problems effectively. Knowledge engineers work closely with domain experts to ensure that the knowledge captured is accurate and relevant. The field plays a crucial role in developing knowledge-based systems (KBS), artificial intelligence applications, and decision support tools that can replicate or augment human decision-making.
