2014 Lecture Notes in Computer Science  
Our prototype of semantics-aware prediction, being used and experimented currently by traffic controllers in Dublin City Ireland, works efficiently with real, live and heterogeneous stream data.  ...  In particular we present a system which integrates numerous sensors (exposing heterogenous, exogenous and raw data streams such as weather information, road works, city events or incidents) to improve  ...  The DL EL ++ [14] is the logic underpinning OWL 2 EL and the basis of many more expressive DL. For the sake of readability we illustrate semantic representations using the DL formalism.  ...
