Abstract
Exception handling has received much attention in several areas recently. In this paper, we accomodate exceptions in a semantic network model using an object-oriented approach. First, the semantic model is adequately described to allow the introduction of exceptions. Then the categories of exceptions in the model are examined. An Object-Property diagram is introduced to model the exceptions. This paper attempts to provide an alternative and better approach in handling exceptions for semantic network models. Specifically, we describe previous work done on exception handling on semantic models and introduce our proposed approach. We show how our model addresses the limitations of the previous approach as well as providing more leverage to the system.
