Knowledge Representation: A Survey of Its Mechanisms, a Sketch of Its Semantics

The paper surveys the field of knowledge representation, a sub-area of artificial intelligence research. It describes the syntactic mechanisms developed in this field for “representing knowledge” in computer systems. Special emphasis is put on highlighting their common properties and distinguishing characteristics. In addition, a clarification will be given of what “knowledge representation” actually means, Le., what it is for a syntactic system to “represent knowledge.”
