Crowdsourced search and locate platform
View Patent ↗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.
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 geolocation 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 geolocation of the object of interest to an administrative user.
2. A method for conducting crowdsourced search and locate operations, the method 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 operation comprising the steps of;
(a) receiving, at the application server, a first list of geolocations, corresponding to a plurality of crowdsourcing participants;
(b) receiving, at the application server computer, a second list of geolocations from a plurality of images;
(b) navigating a first list of geolocations to a specific geospatial location;
(d) sending a first image to a first crowdsourced participant wherein the geolocation of the second list corresponding to the first crowdsourced participant, the geolocation of the second list being substantially the same to the geolocation of the first list corresponding to the first image;
(d) receiving tagging data from the first crowdsourcing participant, the tagging data corresponding to a plurality of objects and locations identified by the first crowdsourcing participant;
(e) retrieving, at a crowdrank server comprising at least a memory, a processor, and programmable instructions stored in the memory and operating in the processor thereof, 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);
(f) 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;
(g) performing 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
(h) providing resulting output values corresponding to the geolocation of the object of interest to an administrative user.
