Abstract

This paper discusses the construction of a Global Semantic Graph (GSG) [1] to support future information- and collaboration-centric applications and services.TheGSGis a publish/subscribe (pub/sub) based architecture that supports publication of tuples and subscriptions with standing graph queries. We believe that an implementation of an efficient pattern matching algorithm such as Rete [2] on top of a distributed environment might serve as a possible substrate for GSG's pub/sub facility. Rete operates on loosely coupled alpha, beta and join nodes and therefore has been chosen by us for implementation in a distributed setting. In this paper, we propose a way to perform Rete's pattern matching over a DHT-based Structured P2P network to provide a scalable contentbased publish/subscribe service.
