The Taub Faculty of Computer Science Events and Talks

This research is concerned with novel Web-related data management scenarios. In particular, we consider database problems which arise from social networks. In the talk, we will overview the main results of this research. In the first part, we introduce the Query Network model, a basic model for social network automation using queries, with its evaluation algorithms and related experiments. We also discuss extensions for the model, and present a few theoretical results. In the second part, we discuss social networks automation using Protocols for Social Networks, which coordinate consistency-preserving decisions in the network. Methods for the concurrent execution of multiple protocol instances, which relax the traditional concurrency control isolation requirement, are presented. In the third part, we describe XPath^L language and system, which combines XPath, an XML query language, and Datalog, by introducing an XPath predicate to the Datalog logic-based formalism. We overview algorithms and related theoretical results.
