This paper presents the first Datalog evaluation engine for executing graph analytics over BSP-style graph processing engines. Building on recent advances in Datalog that support efficient evaluation of aggregates functions, it is now easy for data scientists to author many important graph algorithms succinctly. Without the burden of low-level parallelization and optimization, data scientists can...
There is a growing need for methods that can represent and query uncertain graphs. These uncertain graphs are often the result of an information extraction and integration system that attempts to extract an entity graph or a knowledge graph from multiple unstructured sources [25], [7]. Such an integration typically leads to identity uncertainty, as different data sources may use different references...
There is increasing interest in analyzing networks of all types including social, biological, sensor, computer, and transportation networks. Broadly speaking, we may be interested in global network-wide analysis (e.g., centrality analysis, community detection) where the properties of the entire network are of interest, or local ego-centric analysis where the focus is on studying the properties of...
Graphical user interfaces (GUIs) for today's applications are extremely large. Moreover, they provide many degrees of freedom to the end-user, thus allowing the user to perform a very large number of event sequences on the GUI. The large sizes and degrees of freedom create severe problems for GUI quality assurance, including GUI testing. In this paper, we leverage methods and measures from network...
