Abstract
A crowdsourced search and locate platform, comprising an application server and a crowdrank server. The application server: receives connections from crowdsourcing participants; navigates a first crowdsourcing participant to a specific geospatial location; sends an image corresponding to the geospatial location to the first crowdsourcing participant; receives tagging data from the first crowdsourcing participant, the tagging data corresponding to a plurality of objects and locations identified by the first crowdsourcing participant. The crowdrank server: retrieves a plurality of tags made by participating users computes agreement and disagreement values for each of the plurality of retrieved tags; performs an expectation-maximization or expectation-minimization process iteratively until a configured maximum number of iterations is performed or until an indicia of rate of change between iterations falls below a configured threshold; and provides resulting output values corresponding to geolocations of objects of a plurality of types to an administrative user.
