More and more large data collections are gathered worldwide in various IT systems. Many of them possess a networked nature and need to be processed and analysed as graph structures. Due to their size they very often require the usage of a parallel paradigm for efficient computation. Three parallel techniques have been compared in the paper: MapReduce, its map-side join extension and Bulk Synchronous...
Network structures, especially social networks, grow rapidly and provide huge datasets intractable to analyse. In this paper, two parallel approaches to process large graph structures within the Hadoop environment were compared: Bulk Synchronous Parallel (BSP) and MapReduce (MR). The experimental studies were carried out for two different graph problems: collective classification by means of Relational...
