Description: Information consumption in large-scale distributed systems is currently inadequate. Information consumers are limited to either polling information producers repeatedly in the hope that their query will eventually be satisfied (Internet searching), or giving a coarse-grained description of the information they desire, and then filtering out the many unwanted pieces of information (newsgroups). Publish/subscribe offers a flexible means of specifying interests, such that the burden of information discovery is lifted from the information consumer.This thesis shows that rule-based algorithms, particularly the Rete algorithm, are well-suited to performing the task of disseminating information from publishers to subscribers. A framework for mapping from the language of rule-based systems to publish/subscribe systems is detailed, and experimental data is presented to confirm that Jess, a rule-based Java implementation of Rete, performs well as the core of an information broker in the distributed publish/subscribe application, PADRES.
