In this paper we propose a new framework for dynamic distributed query processing based on so-called HyperQueries which are essentially query evaluation sub-plans “sitting behin...
This paper considers a multi-query optimization issue for distributed similarity query processing, which attempts to exploit the dependencies in the derivation of a query evaluati...
