Unfold the City: Excavation and Analysis of Latent Spatial-temporal Urban Data
by Takuro Yonezawa (Keio University, Japan)
ABSTRACT
Smart city, though there exist several definitions for it, is defined as a complex ecosystem characterized by the intensive use of information and communication technologies, aiming at making the cities more efficiency, more attractive, more sustainable and a unique place for innovation and entrepreneurship. One promising way toward making city smarter is to understand city deeply and real-time based on large amount of heterogeneous city data. However, excepting several social network service data or some advanced cities filled with IoTs, acquiring valuable spatial-temporal city data is still the first obstacle to solve for most of the cities. In this talk, I will present our approach of how we leverage existing city resources which exist in any cities to excavate latent city data, and how we share and analyze the data for understand the city, with over-three years experiments in Fujisawa city, Japan. Furthermore, I will discuss further challenges and many opportunities that smart city, and smart society faces.
BIOGRAPHY
Takuro Yonezawa is a research assistant professor in Graduate School of Media and Governance, Keio University, Japan. He received Ph.D. degree in the Media and Governance from Keio University in 2010. His research interests are the intersection of the distributed systems, human-computer interaction and sensors/actuators technologies. He is also leading several smart city projects as a technical coordinator, such as FP7/NICT European-Japanese collaborative research project (ClouT project), NICT social big data project, MIC G-Space city project, and so on. He was awarded IBM Ph.D. Fellowship Award (2009) and IPSJ Yamashita SIG Research Award (2013).
