A Graphical Interactive Tool for KBS Maintenance
Although KBSs are now well established, very little work has been carried out concerning the maintenance of these systems. In this paper a KBS maintenance tool is described designed to assist maintenance engineers in the task of maintaining the Rule Bases (RBs) of KBSs. The tool is directed at KBSs built using an intermediate representation, between the source and the final Rule base, which is isomorphic with the source i.e. that reflects the structure of the source data. Essentially, the Datamap tool described allows the maintenance engineer to navigate round the intermediate representation to identify suspect Rules. This is achieved using two directed biparteid graphs which graphically display the connections between elements within individual Rules and the connections between the Rules themselves. In addition a number of facilities are provided to allow the user to interact with the graphical displays and obtain answers to questions concerning KB maintenance. These facilities support maintenance activities where judgements are required on behalf of the maintenance engineer.
