A Semantics-Supported Publish/Subscribe System

For the low matching accuracy caused by heterogeneous information in content-based publish/subscribe systems,by defining the relationship among the attributes of events and subscription,a design method of semantics-supported publish/subscribe is proposed using the semantic conversion module.And it is applied to the publish/subscribe system of SINEA.The experimental results show that the method supports different semantics to a certain extent,and improves the accuracy of matching.
