Abstract：Situation awareness (SA) is the perception of environmental elements and events, the comprehension of their meaning, and the projection of their future status. Conventional SA system is based on physical sensors. In this talk, a recently developed situation awareness system based on social sensing will be introduced. Causal relation extraction, which is one of the main components of the SA system, will then be elaborated. The causal relation extraction is based on a new framework of knowledge and data integration, implemented through knowledge and data driven convolutional neural networks (CNN). The knowledge-driven CNN ensures good generalization of the system, while the data-driven CNN ensure details of samples are taken care of. Experiment results will be presented to show the performance of the new framework.
