Resumen
There is no set of general guidelines for evaluating Knowledge Sharing Technology (KST) and specific ideas for evaluating user-independent ontologies. Instead of starting from the beginning, this paper discusses similarities and differences between knowledge bases (KB) and ontologies. The idea is to learn from Knowledge Base Systems' evaluation and assessment by picking up some successful ideas and adapting them to the domain of the ontologies. We also learn from its mistakes by avoiding them. The paper also describes how different agents that use ontologies with different aims have different concerns in the evaluation and assessment processes. Definitions and criteria for the terms: "Evaluation", "Verification", "Validation" and "Assessment" in the knowledge sharing domain are also given.
