A '''knowledge-based system''' ('''KBS''') is a [[computer program]] that [[automated reasoning|reasons]] and uses a [[knowledge base]] to [[problem solving|solve]] [[complex systems|complex problems]]. Knowledge-based systems were the focus of early [[artificial intelligence]] researchers in the 1980s. The term can refer to a broad range of systems. However, all knowledge-based systems have two defining components: an attempt to represent knowledge explicitly, called a [[knowledge base]], and a [[reasoning system]] that allows them to derive new knowledge, known as an [[inference engine]].
