Social pixels: genesis and evaluation
Huge amounts of social multimedia is being created daily by a combination of globally distributed disparate sensors, including human-sensors (e.g. tweets) and video cameras. Taken together, this represents information about multiple aspects of the evolving world. Understanding the various events, patterns and situations emerging in such data has ions in multiple domains. We develop abstractions and tools to decipher various spatio-temporal phenomena which manifest themselves across such social media data. We describe an approach for aggregating social interest of users about any particular theme from any particular location into `social pixels'. Aggregating such pixels spatiotemporally allows creation of social versions of images and videos, which then become amenable to various media processing techniques (like segmentation, convolution) to derive semantic situation information. We define a declarative set of operators upon such data to allow for users to formulate queries to vi...
