Using Ontologies to Improve Performance in a Web System - A Web Caching System Case of Study

This paper gives the details of a web system architecture which uses ontologies to improve the behavior of the system from a performance point of view. The architecture presented is implemented in a cache level. As web system performance depends on states and parameters fixed in runtime period, the configuration of our system will be changed during that period. We need to monitor the system and store those gathered information. A knowledge base is used to store those information and measures. We propose the use of reasoners that use that gather information in the K.B. to change the configuration and setup of the system during runtime period. That configuration also is modelled by a knowledge base which use ontological languages.
