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.

主权项

1. A crowdsourced search and locate platform, comprising:
an application server computer comprising at least a memory and a processor and coupled to a digital packet network; and a crowdrank server comprising at least a memory, a processor, and programmable instructions stored in the memory and operating in the processor and coupled to the application server, the instructions adapted to a crowdsourced search and locate platform; wherein the application server:
(a) receives, at the application server, a first list of geolocations corresponding to a plurality of crowdsourcing participants stored in a database;(b) receives, at the application server, a second list of geolocations corresponding to images stored in the database;(c) navigates a first crowdsourcing participant corresponding to the first list of geolocations to a specific geospatial location;(d) sends an image corresponding to the second list of geolocation where the geospatial location of the second list is substantially similar to the geolocation of the first list; and(e) 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; and wherein the crowdrank server determines a real geospatial location of an object of interest by:
(f) retrieving a plurality of tags corresponding to the object of interest, the tags made by participating users by repeated carrying out of steps (a) through (d);(g) computes 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;(h) automatically 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(i) provides resulting output values corresponding to the geolocations of the object of interest to an administrative user.
