Interactive classification: a technique for building and maintaining knowledge bases
December 3, 1984
The practical application of knowledge-based systems, such as expert systems, often requires the maintenance of large amounts of declarative knowledge. As a knowledge base grows in size and complexity, it becomes more difficult to maintain and extend. Even someone who is familiar with the representation and the contents of the existing knowledge base may introduce inconsistencies and errors whenever an addition or modification is made. This paper describes an approach to this problem based on a tool called an interactive classifier. An interactive classifier uses the contents of the existing knowledge base and knowledge about its representation to help the maintainer describe new knowledge base objects. The interactive classifier will identify the appropriate taxonomic location for the newly described object and add it to the knowledge base. The new object is allowed to be a generalization of existing knowledge base objects, enabling the system to learn more about existing objects.
