In a Smarter City, available resources are harnessed safely, sustainably and efficiently to achieve positive, measurable economic and societal outcomes. Data (and then information) from people, systems and things in cities is the single most scalable resource available to City stakeholders but difficult to publish, organize, discover, interpret, combine, analyze, reason and consume, especially in such an heterogeneous environment. Indeed data is big and exposed from heterogenous environments such as water, energy, traffic or building.
Most of the challenges of Big Data in Smart Cities are multi-dimensional and can be addressed from different multidisciplinary perspectives e.g., from Artificial Intelligence (Machine Learning, Semantic Web), Database, Data Mining to Distributed Systems communities.
Enabling City information as a utility, through a robust (expressive, dynamic, scalable) and (critically) a sustainable technology and socially synergistic ecosystem, could drive significant benefits and opportunities.
While research efforts in Big Data have mostly focused on the later stages of the process of making sense of the sea of data (e.g. data analytics, query answering, data visualization, etc), in the context of Smart Cities, where heterogeneous data originates from multiple municipal and state agencies with little to no coordination, major hurdles and issues continue to impede progress toward these later stages. These key unaddressed issues are often related to information exploration, access, and linking: e.g.,
1) How to efficiently figure out and access data sources relevant to a given task?
2) How to discover implicit relevant links between these information sources at the data level?
3) How to determine relevant data in the selected linked data sources?
Today, these challenges are tackled in mostly ad-hoc and labor intensive data integration efforts. It is becoming increasing clear that, without the advent of novel, scalable and semi-automated data integration techniques, this first data access and linking stage will soon represent a major bottleneck to the whole process of extracting valuable information from the increasing number data sources and volume of data available to decision makers.
