Abstract: An aspect includes identifying, by a processor, a plurality of data sources associated with a defined geographic area. A plurality of scheduling data associated with a plurality of users is gathered from the data sources across a communication network. One or more shared activities and interests are identified based at least in part on the scheduling data and/or overlapping and similar proximity of user locations. One or more community networks that link two or more of the data sources are created based at least in part on the one or more shared activities and interests. One or more notifications associated with the one or more shared activities and interests are distributed across the one or more community networks.
