Abstract:

For the low matching accuracy caused by heterogeneous information in content-based publish/subscribe systems, by defining the relationship among the a ttributes 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.

Key words: event, subscription, semantic conversion
