Yu Lai Song, Yan Xiang Wu, Lingling Qiao · Journal of Communication and Computer · 2009
The use of violence matching algorithm in the Publish/Subscribe system impacts the system time. This paper establishes the constraint collections, the events constraint collections and the mapping list of subscription constraint through decomposing and treating the subscribed news. Furthermore, this paper makes use of the multi-dimensional index to match the event which is in accordance with the subscribed information quickly, and discusses the matching effect of different parameters as well. It is indicated that this method can shorten the matching time and improve the performance of the system effectively.
