Heterogeneous Crowdsourced Data Co-mining for Smart Cities (HCDCSC)

Advances in computing, communications, storage, and sensing technologies have enabled to digitalize and record citizens’ traces while interacting with cyber-physical spaces. We have entered an era where such data are becoming increasingly big and easily available. These data are heterogeneous, contributed by the crowd in the cities, coming from different sources and with diverse formats. Broadly, such data are generated mainly from three sources: Internet and Web applications, sensor networks, and mobile/wearable devices. The scale and richness of the multimodal, mixed data sources present us an opportunity to compile the data into a comprehensive picture of individual’s daily life facets, transform our understanding of our lives, organizations and societies, and enable completely innovative urban services for smart cities, including public transportation, public safety, city resource management, environment monitoring, and social interaction assistance. However, the raw data cannot be used directly, and the emerging analytical techniques, including big data analytics, text and image analytics, network and mobile analytics need to be studied and applied, according to the specific applications. In the big data era, novel architectures, methodologies, and techniques must be also developed, in order to bring citizens closer to the vision of a smart city (i.e. improving the living quality/safety of citizens, sustainable city development, and so on).
