Indirect crowdsourcing by associating data from multiple data sources

A computer program product for supplementing direct crowdsourcing data, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a computing device to cause the computing device to:

• monitor user device activity from a plurality of user devices;
• store indirect crowdsourcing data records that identify the user device activity;
• detect that the level of user device activity within an area exceeds a threshold;
• determine the presence of a crowdsourcing event based on the detecting that the level of user device activity within the area exceeds the threshold;
• and
• output information indicating the presence of the crowdsourcing event.

A system comprising:

• a CPU, a computer readable memory and a computer readable storage medium associated with a computing device;
• program instructions to receive direct crowdsourcing data;
• program instructions to identify a crowdsourcing event from the direct crowdsourcing data;
• program instructions to establish a geofence based on the identified crowdsourcing event;
• program instructions to monitor indirect crowdsourcing activity within the geofence;
• program instructions to generate and store indirect crowdsourcing data records with analytics data associated with the crowdsourcing event;
• program instructions to determine attributes of publically posted content associated with the indirect crowdsourcing data;
• program instructions to update the indirect crowdsourcing data records with the determined attributes;
• program instructions to receive a crowdsourcing event query;
• and
• program instructions to generate and provide a response to the crowdsourcing event query,
• wherein the program instructions are stored on the computer readable storage medium for execution by the CPU via the computer readable memory.
