A typical location extraction approach consists of two steps, location name detection and location entity disambiguation. Promising results have been obtained in the last decade based on natural language processing technologies. However, there are still two challenges which requires further investigation: 1)How to leverage the prior and contextual evidence(More)
An integrated strategy incorporating computational fluid dynamics (CFD) and GIS technologies is proposed to simulate the flow fields and associated concentration distributions from contaminant releases in complex urban settings. CFD is able to provide realistic simulations for geometrically complex scenarios, however, inadequate of geometry construction for(More)
