Deep semantics inspection over big network data at wire speed

Deep semantics inspection (DSI), proposed in this article, reveals the semantics behind big network data on the fly. The key idea of DSI is to obtain a sketch of user behavior at wire speed, with a size several orders of magnitude smaller than that of raw data. Then semantics analysis is applied to the obtained sketch. To demonstrate the use of DSI, this article also presents several practical user scenarios leveraging on the DSI system designed.
