Until 2014, I had worked on the cloud & big data and was trying to enable the convergence service for Samsung smart devices using multiple smart devices such as smart TV, smart phone and various smart devices. Particularly I was in charge of the design and development of the convergence metadata where I was chairing the Media Annotation Working Group in W3C as to develop an Ontology and API designed to facilitate cross-community data integration of information related to media objects on the web from 2008.
