Research and Implementation of Ontology Modularization for Logistics
Wang Jia-fan · Journal of Tianjin University Science and Technology · 2009
Modularization was introduced to logistic ontology to solve the problem of the maintainability and usability of large logistic ontology.The definition of ontology module and the division principles for the logistic problem domain were proposeda,nd assertions were defined to link the ontology modules to represent knowledge in different contexts.Considering that inconsistency may occur during linking the modulesc,onstraints were used to guarantee the accuracy of links between modules.As the cargo module was still large after modularizationc,argo module was decomposed into multi-modules accord-ing to the characteristic of cargo field.Therefore the relationship between the modules was restricted to be simple trees and modules were linked by procedures.With the method proposed in this papert,he logistic system based on ontology and rule was optimized.The experiments show that the logistic ontology modularization restricts the reasoning in an acceptable scope and simplifies the complexity of reasoning.The resource usage and the response time of the system are reduced.Meanwhile,the logistic ontology modularization enhances the maintenance and reusability of ontology modules.
