ABSTRACT:

Social computing is transforming on-line spaces with popular applications such as social-networking (e.g. Facebook), collaborative authoring (e.g. Wikipedia), social bargain-hunting (e.g. Groupon), etc. Spatio-temporal constraints are becoming a critical issue in social computing with the emergence of location-based social-networking, Volunteered Geographic Information, Participative Planning, etc. Location-based social networks (e.g. foursquare.com and the .Places Check-in. feature on Facebook) facilitate socialization with nearby friends at restaurants, bars, museums, and concerts. Volunteered Geographic Information (e.g. Wikimapia, OpenStreetMap, Google MyMaps) allows Internet users to participate in generation of geographic information.

The slides address the following questions:
