Abstract
Over recent years, there has been an emerging interest in supporting social media analysis for marketing, opin- ion analysis and understanding community cohesion. Social media data conforms to many of the categorisations attributed to “big-data” – i.e. volume, velocity and variety. Generally analysis needs to be undertaken over large volumes of data in an efficient and timely manner. A variety of computational infrastructures have been reported to achieve this. We present the COSMOS platform supporting sentiment and tension analysis on Twitter data, and demonstrate how this platform can be scaled using the OpenNebula Cloud environment with Map/Reduce-based analysis using Hadoop. In particular, we describe the types of system configurations that would be most useful from a performance perspective – i.e. how virtual machines in the infrastructure should be distributed to reduce variability in the analysis performance. We demonstrate the approach using a data set consisting of several million Twitter messages, analysed over two types of Cloud infrastructure.
