Looking at Slideshare, I cam across two new interesting presentations.
The first one by Ramesh Jain, entitled: "multimedia & big data". Ramesh used the analog of the "blind men trying to understand what is an elephant" that I also used before in another context, and says that we create silos by the different senses (and media), and discusses the integration of all events grasped by the different senses (and media) to create storytelling. He discusses some of the challenges of situation modelling and detection in that environment. The challenges and directions are certainly where I believe the world, and the value of big data are taking us.
The second presentation is by WS02, a Sri-Lanka based company, introducing their complex event processor AKA Siddhi. This is presented in the context of big data and describes the architecture and the language.
