Crowdsourced search and locate platform

摘要

A crowdsourced search and locate platform, comprising an application server and a client interface application. 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 client interface application: displays elements enabling an administrative user to configure a crowdsourced search and locate campaign; displays other elements enabling an administrative user to configure and run a crowdrank algorithm; and upon the user's selecting a particular object type icon, displays tags of the type selected by placing visual indicators at each tagged location of objects of the selected type within the plurality of image strips.

1. A crowdsourced search and locate platform, comprising:
an application server computer comprising at least a memory and a processor coupled to a digital packet network and programmable instructions stored in the memory and operable in the processor to provide a client interface application wherein the instructions are adapted to a crowdsourced search and locate platform comprising:
a first list of geolocations corresponding to a plurality of crowdsourced participants stored in a database;a second list of geolocations corresponding to images stored in the database; wherein the client interface application:
sends images to crowdsourced participants wherein the corresponding geolocation of the second list is substantially the same as the geolocation of the first list;receives tagging data from the crowdsourced participants, the tagging data corresponding to a plurality of objects and locations identified by the crowdsourced participants;displays a first plurality of elements enabling an administrative user to configure a crowdsourced search and locate campaign;displays a second plurality of elements enabling an administrative user to configure and run a crowdrank algorithm, wherein the crowdrank algorithm takes as input a large number of object tags created by participating users in the crowdsourced search and locate campaign and determines a most likely distribution of actual locations of objects of interest;displays a plurality of image strips that were viewed by participating users in the crowdsourced search and locate campaign; andupon the user's selecting a particular object type icon, displays all or a substantial portion of tags of the type selected that were generated by participating users in the crowdsourced search and locate campaign, by placing visual indicators at each tagged location of objects of the selected type within the plurality of image strips; wherein the crowdrank algorithm performs the steps of:
computing a vector of agreement and disagreement values for each of the plurality of retrieved tags, wherein each agreement or disagreement value is determined by comparing a distance between a location associated with a first retrieved tag with which a first vector is associated and a location associated with a second retrieved tag; andautomatically 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.
