✦ Synopsis

The assimilation of information obtained from domain experts into an existing knowledge base is an important facet of the knowledge acquisition process. Knowledge assimilation requires an understanding of how the new information corresponds to that already contained in the knowledge base and how this existing information must be modified so as to reflect the expert's view of the domain. This paper describes a system, KnAc, that modifies an existing knowledge base through a discourse with a domain expert. Using heuristic knowledge about the knowledge acquisition process, KnA c anticipates modifications to existing entity descriptions.

These anticipated modifications, or expectations, provide a context in which to assimilate new domain information.
