The abundance of online media content requires highly scalable architectures to allow cross-media monitoring targeted to specific needs of marketers. We will present an innovative big data-as-a-service platform for analysing large complex networks in order to enhance cross-media monitoring.

In contrast to existing systems, our platform provides marketers with several distinctive features: First, while most of the systems perform quantitative exploratory analysis of social media, our platform applies graph analytics in order to reveal social interaction types, hidden patterns in the cross-media network and the information diffusion over time. The graph animation gives marketers a better understanding about the formation of communities, propagation of the content, etc.

Second, the creation of cross-media graphs is triggered by user-defined queries that can be easily specified by marketers. Thus, end-users can build and analyse different graphs according to specific goals of the analysis.
Third, the platform allows reducing Hadoop cluster usage costs due to executing big data analytics operations on demand triggered by user-defined queries. Instead of running costly streaming processes that continuously listen for new queries, we implemented Spark-as-a-service via Apache Livy REST interface. It allows running batch Spark jobs on demand.

Finally our platform integrates distributed versions of graph analytics algorithms (Louvain, HITS and other algorithms) that can scale to a large volume of data.
During our presentation we will showcase how you can harness all these features of the platform in order to dig into details of complex cross-media networks.
