A good knowledge representation enables fast and accurate access to knowledge and understand of the content.
A knowledge representation system should have following properties.
- Representational Adequacy: The ability to represent all kinds of knowledge that are needed in that domain.
- Inferential Adequacy: The ability to manipulate the representational structures to derive new structures corresponding to new knowledge inferred from old.
- Inferential Efficiency: The ability to incorporate additional information into the knowledge structure that can be used to focus the attention of the inference mechanisms in the most promising direction.
- Acquisitional Efficiency: The ability to acquire new knowledge using automatic methods wherever possible rather than reliance on human intervention.
