Keynote Speech 1: The tragedy of the (Data) Commons
Time: 9:00-10:20, September 18, 2020
Prof. James Hendler, Rensselaer Polytechnic Institute
Abstract: The tragedy of the commons, first proposed by William Lloyd in 1833, is an economic problem in which every individual has an incentive to consume a resource at the expense of every other individual with no way to exclude anyone from consuming. It results in overconsumption, under investment, and ultimately depletion of the resource. While the direct application of these principles to data seems like a bit of a reach, it becomes clear that data sharing risks much of the same problem - people wishing to protect their own data while having access to other people’s. Motivation for sharing is thus weak, until incentives and policies are in place. However, now that these incentives and policies are coming into practice, the implementation will have high impact on the benefits. Thus, as we work to make the world a FAIRer place, we must consider how the way data, and especially metadata, is represented and shared.

Keynote Speech 2: Towards efficient computation of network structural stability
Time: 10:40-12:00, September 18, 2020
Prof. Xuemin Lin, The University of New South Wales
Abstract: With the emergence of large-scale networks, the study of network structural stability has recently received a great deal of attention in different areas such as social networks, the world wide web, and biology. The stability of a network indicates the ability of the network to maintain an acceptable level of service and/or to defend the attacks from the competitors. In this talk, we first introduce the stability models in different domains, their applications, and unique challenges that need to be addressed. We focus on three fundamental problems: (a) efficiently computing the stability of a given network, (b) motivating critical nodes and edges to enhance the network stability, and (c) defending critical nodes and edges against the attacks to network stability. Due to the fast evolvement of real-life networks, we also discuss the stability problems and their computation on dynamic graphs. We will explore the nature and lay the scientific foundation of these problems. Subsequently, we introduce novel computing paradigms and algorithms, indexing techniques, batch processing techniques, and distributed solutions. Finally, we discuss the future research directions in this important and growing research area.

Keynote Speech 4: Entity Linking and Data Privacy Protection for Spatiotemporal Data
Time: 10:40-12:00, September 19, 2020
Prof. Xiaofang Zhou, The University of Queensland
Abstract: Spatial trajectory analytics involves a wide range of research topics including data management, query processing, data mining and recommendation systems. It can find many applications in intelligent transport systems, social media analysis, location-based systems, urban planning and smart city. New opportunities arise with massive and rapidly increasing volumes of high-quality spatiotemporal data from many sources such as GPS devices, mobile phones and social network applications. Integrating trajectory data is a fundamental step for making sense of spatiotemporal data. In this talk we will discuss our recent work on spatiotemporal entity linking and privacy protection for moving objects data.
