Implementations
- Frame Representation Language (FRL), 1977, Roberts/Goldstein.
- Two examples of frame- or frame based- languages are OIL and F-logic.
- An editor for frame-based ontologies is Protégé.
- The Knowledge Machine (KM) is a knowledge representation language and reasoning engine. The knowledge is represented as frames, but KM is also influenced by logic. This combination makes KM very expressive and provides it with a clear, formal semantics.
- KL-ONE is a well known knowledge representation system in the tradition of semantic networks and frames. The system is an attempt to overcome semantic indistinctness in semantic network representations and builds upon the idea of Structured inheritance networks.
