Soar: Uniform Representation of Knowledge

Description

• All knowledge in Soar is represented as productions
  • Each production represents a retrieval of a piece of knowledge from long-term memory
  • The right side of the production represents the knowledge; the left side represents the conditions under which it is appropriate to retrieve that knowledge into working memory
• Productions represent both knowledge about the world and control knowledge
• Working memory holds Soar's short-term context, consisting of a collection of interrelated objects. All objects are described by attribute-value pairs, where some object identifiers are used as attributes and values of other objects
