摘要：Emergency alert and messaging systems are commonly employed to serve users when emergency situation occurs. Emergency situations require utmost importance in terms of nearness, speed and accuracy of response. However, most of the researches in literature are incapable of deriving accurate and efficient response to a user query leaving most of solutions to be location based. We see that utilization of user's context information and social network relations can further improve emergency alert systems. With this opportunity, we proposed an approach that utilizes important context information to provide accurate and fast response to an occurring emergency. This proposed framework is applicable for both low (e.g. flat tire and vehicle repair) and high domain danger types (e.g. fire and natural calamities) emergency situation. Within its architecture, we identify several key factors such as participatory scheme, context management, and service management with decision support rules that enable the development of an efficient and practical framework for emergency situations
