Mission Statement

Spatial Information and Intelligence laboratory supports research activities that integrate computer vision, natural language understanding, human-computer conversation interactions /HCI, geographical information systems /visualization, collaborative systems, and geospatial decision-support technologies to address the grand challenge of large-scale, geocollabrative applications in digital government. Crisis management, and civic engagement.

Active Projects

Understanding Patterns of Analytical Reasoning with Big Data: Towards a Cognitive Foundation of Human-machine Cooperation in Visual Analytics, College of IST Research Seed Grant. 2018-2020, Cai, G. (PI), Zhang, L. (Co-PI)

Geodeliberation: Enabling Democratic Decision-Making in Local Communities Through Place-Based Deliberative Dialogues. National Science Foundation (IIS-1211059) 2012-2018, PI: Cai, G. (PI) and : Carroll, J.M. (Co-PI).

. GeoDeliberation involves the use of advanced information technologies to enhance and expand civic engagement in local communities and governments. The project partners with the State College Borough to understand human and information issues around large-scale public participation of urban planning activities. New understanding from the field research informs the development of GeoDeliberator tool.

Conversational support for Geospatial Analysis
