Various studies have This demonstrates that the proposed framework is feasible and been done on extracting urban and social intelligence from the reasonable. Our preliminary findings reveal that, first, tobacco- related content grows exponentially. In particular, the growth of collected data from participatory media, such as social relation- the protobacco group follows the exponential law, whereas there ship mining, social recommendation, location recommendation, is linear growth for the tobacco control group. Second, the con- etc. In this paper, we address a different problem over intelligent nection between the tobacco control community and the tobacco IoT. We aim to automatically collect and analyze large-scale cessation community is tight, whereas the nodes in the protobacco tobacco-related data sets with the help of the unprecedented community are connected sparsely. Finally, the collective emotion in tobacco communities is negative. sensing capability of intelligent IoT.
