Determining object geolocations based on heterogeneous data sources
An example method of determining geolocations of objects based on information retrieved from heterogeneous data sources comprises: receiving, from a first data source associated with an object by an ontology-defined relationship, a first dataset including a first data item specifying a first time identifier and a first geolocation associated with the object; receiving, from a second data source associated with an object by an ontology-defined relationship, a second dataset including a second data item specifying a second time identifier and a second geolocation associated with the object; and determining, by applying a rule set associated with the ontology to the first dataset and the second dataset, a geolocation of the object and a corresponding time identifier.
1. A method, comprising:
identifying, by a computer system, a secondary object associated, by a first relationship specified by a hierarchical ontology, with an object of interest, wherein the first relationship indicates at least a transient physical association of the secondary object with the object of interest;
identifying a first data source and a second data source that are associated, by the hierarchical ontology, with the secondary object;
receiving from the first data source associated with the secondary object by a second relationship specified by the hierarchical ontology, a first dataset including a first data item specifying a first time identifier and a first geolocation associated with the secondary object;
receiving, from the second data source associated with the secondary object by a third relationship specified by the hierarchical ontology, a second dataset including a second data item specifying a second time identifier and a second geolocation associated with the secondary object; and
determining a first priority associated with the first dataset and a second priority associated with the second dataset;
resolving, based on the first priority and the second priority, a conflict with respect to the first data item and the second data item;
determining, by applying a first rule set associated with the ontology to the first dataset and the second dataset, a geolocation of the object of interest and a corresponding time identifier; and
determining, based on an attribute of a fourth relationship between the data source and the object of interest, a confidence level associated with the geolocation of the object of interest.
2. The method of claim 1 , further comprising:
storing the geolocation of the object of interest and the corresponding time identifier in an object database implementing the ontology.
3. The method of claim 1 , further comprising:
receiving a geolocation data request specifying the object of interest; and
transmitting a response specifying the geolocation of the object of interest and the corresponding time identifier.
4. The method of claim 1 , wherein determining the geolocation of the object of interest further comprises:
interpolating the geolocation of the object of interest at a time frame between a first time identified by the first time identifier and a second time identified by the second time identifier.
5. A system, comprising:
memory; and
one or more processors coupled to the memory, the one or more processors configured to:
identify a secondary object associated, by a first relationship specified by a hierarchical ontology, with an object of interest, wherein the first relationship indicates at least a transient physical association of the secondary object with the object of interest;
identify a first data source and a second data source that are associated, by the hierarchical ontology, with the secondary object;
receive, from a first data source associated with the secondary object by a second relationship specified by the hierarchical ontology, a first dataset including a first data item specifying a first time identifier and a first geolocation associated with the secondary object;
receive, from a second data source associated with the secondary object by a third relationship specified by the hierarchical ontology, a second dataset including a second data item specifying a second time identifier and a second geolocation associated with the secondary object;
determine a first priority associated with the first dataset and a second priority associated with the second dataset;
resolve, based on the first priority and the second priority, a conflict with respect to the first data item and the second data item;
determine, by applying a rule set associated with the ontology to the first dataset and the second dataset, a geolocation of the object of interest and a corresponding time identifier; and
determine, based on an attribute of a fourth relationship between the data source and the object of interest, a confidence level associated with the geolocation of the object of interest.
6. The system of claim 5 , wherein the one or more processors are further configured to:
store the geolocation of the object of interest and the corresponding time identifier in an object database implementing the ontology.
7. The system of claim 5 , wherein the one or more processors are further configured to:
receive a geolocation data request specifying the object of interest; and
transmit a response specifying the geolocation of the object of interest and the corresponding time identifier.
8. The system of claim 5 , wherein determining the geolocation of the object of interest further comprises:
interpolating the geolocation of the object of interest at a time frame between a first time identified by the first time identifier and a second time identified by the second time identifier.
9. A non-transitory computer readable storage medium comprising executable instructions that, when executed by a computer system, cause the computer system to:
identify a secondary object associated, by a first relationship specified by a hierarchical ontology, with an object of interest, wherein the first relationship indicates at least a transient physical association of the secondary object with the object of interest;
identify a first data source and a second data source that are associated, by the hierarchical ontology, with the secondary object;
receive, from the first data source associated with the secondary object by a second relationship specified by the hierarchical ontology, a first dataset including a first data item specifying a first time identifier and a first geolocation associated with the secondary object;
receive, from the second data source associated with the secondary object by a third relationship specified by the hierarchical ontology, a second dataset including a second data item specifying a second time identifier and a second geolocation associated with the secondary object;
determine a first priority associated with the first dataset and a second priority associated with the second dataset;
resolve, based on the first priority and the second priority, a conflict with respect to the first data item and the second data item;
determine, by applying a rule set associated with the ontology to the first dataset and the second dataset, a geolocation of the object of interest and a corresponding time identifier; and
determine, based on an attribute of a fourth relationship between the data source and the object of interest, a confidence level associated with the geolocation of the object of interest.
10. The non-transitory computer readable storage medium of claim 9 , further comprising executable instructions that, when executed by the computer system, cause the computer system to:
store the geolocation of the object of interest and the corresponding time identifier in an object database implementing the ontology.
11. The non-transitory computer readable storage medium of claim 9 , further comprising executable instructions that, when executed by the computer system, cause the computer system to:
receive a geolocation data request specifying the object of interest; and
transmit a response specifying the geolocation of the object of interest and the corresponding time identifier.
