First some pearls on ideal characteristics of knowledge representation (KR) formats:
- Coverage, which means the KR covers a breath and depth of information.
- Understandable by humans. KR is viewed as a natural language, so the logic should flow freely. It should support modularity and hierarchies of classes (Polar bears are bears, which are animals). It should also have simple primitives that combine in complex forms.
- Consistency. If John closed the door, it can also be interpreted as the door was closed by John. By being consistent, the KR can eliminate redundant or conflicting knowledge.
- Efficient.
- Easy to modify and update.
- Supports the intelligent activity which uses the knowledge base.
Then I discover an entire page dedicated to ontology engineering. Stay posted ;-)
