2021 ACSW – Keynote Presentation: Civil Computing: Making Geospatial Data Usable for Social and Urban Good

Abstract

In this talk I will introduce Civil Computing, our attempt to use geospatial data to improve people’s life quality and cities’ liveability. We focus on four typical beneficial domains (i.e., House Seeking, Site Selection, Transport Optimization, and Trip Planning) and three typical forms of geospatial objects (i.e., points of interest, areas of interest, and trajectories), with the mission of delivering real value, both as insights to non-technical decision-makers and as benefits to society. For each domain and data type above, I will first give an overview of our efforts in the field of data management and data mining respectively, followed by a zoom-in to elaborate typical research questions inspired from our system building. These research questions include but not limit to spatial object selection for interactive visualization on maps, spatial object recommendation with hints, incremental user preference adjustment, rank aggregation query over streaming spatial objects, trajectory-driven site selection, travel time estimation, traffic pattern identification, bus route design and trip planning. Throughout this talk, I will also share the lessons learned in complementing our research with system prototypes development, from which we incrementally identify (new) practical pain points, formulate research questions, analyze their hardness, and develop algorithms that can bridge the gap between theory and practice.

Biography

Associate Professor Bao has made groundbreaking contributions in the area of large-scale spatial data management, mining and retrieval. In these different areas, he developed novel query models, robust algorithms, visual analytic processes and systems that deliver insights to non-technical decision makers and benefits to society. His research applies directly to transportation optimization, advertisement placement, and search query answering about road networks
