Zhida Chen, Gao Cong, Zhenjie Zhang, Tom Z.J. Fu, Lisi Chen
2017 arXiv   pre-print
In this paper, we propose our distributed publish/subscribe system, called PS2Stream, which digests a massive spatio-textual data stream and directs the stream to target users with registered interests  ...  Publish/subscribe systems enable efficient and effective information distribution by allowing users to register continuous queries with both spatial and textual constraints.  ...  This calls for a distributed solution to building a publish/subscribe system over the spatio-textual data stream.  ...

Predictive publish/subscribe matching

Vinod Muthusamy, Haifeng Liu, Hans-Arno Jacobsen
2010 Proceedings of the Fourth ACM International Conference on Distributed Event-Based Systems - DEBS '10  
A new publish/subscribe capability is presented: the ability to predict the likelihood that a subscription will be matched at some point in the future.  ...  Furthermore, a comparison with a hand-crafted Markov model using real data traces shows that the algorithm consumes much less memory and processing power, yet still delivers prediction precision that approaches  ...  Unlike conventional publish/subscribe approaches, the P-ToPSS model developed in this paper operates over event streams, where an event stream, E, is interpreted as an infinite sequence of events, and  ...
