Abstract

The present disclosure provides a method comprising receiving, from a first data source, information for a flight object comprising a first set of fields and corresponding values that describe a first flight. The method further comprises retrieving global identifier record(s) from a database. Each global identifier record comprises a unique global identifier for a respective flight and a respective second set of fields and corresponding values of the database that describe the respective flight. The method further comprises calculating, based on a comparison of the first set with some or all of the respective second set(s), a respective confidence value for each pairing of the flight object with a respective one of the global identifier record(s). The method further comprises updating, when a calculated confidence value exceeds a threshold value, the global identifier record corresponding to the calculated confidence value using information from the first set.

First claim

What is claimed is:

1 . A method comprising:
receiving, from a first data source, information for a flight object comprising a first set of fields and corresponding values that describes a first flight; retrieving one or more global identifier records from a database, each global identifier record comprising a unique global identifier for a respective flight and a respective second set of fields and corresponding values of the database that describe the respective flight; calculating, based on a comparison of the first set with some or all of the one or more respective second sets, a respective confidence value for each pairing of the flight object with a respective one of the one or more global identifier records; and updating, when a calculated confidence value exceeds a threshold value, the global identifier record corresponding to the calculated confidence value using information from the first set.

2 . The method of claim 1 , further comprising:
determining whether the information for the flight object was previously recorded in a first table of the database corresponding to the first data source; and when the information for the flight object was not previously recorded, recording the information for the flight object in the first table.

3 . The method of claim 1 , further comprising:
receiving, from a second data source, information for a second flight object corresponding to the first flight; recording information for the second flight object in a second table of the database corresponding to the second data source; and updating the global identifier record corresponding to the first flight using the information for the second flight object.

4 . The method of claim 1 , wherein calculating the respective confidence value for each pairing comprises:
initializing the confidence value to an initial value; comparing, for each field of a predefined plurality of fields, the corresponding values of the first set and of the respective second set for the field; and updating the confidence value based on the comparisons.

5 . The method of claim 4 , further comprising:
determining, for at least one field of the predefined plurality of fields, one or both of the first set and the respective second set do not include a value for the field; and applying, for the at least one field, a predefined penalty factor to the confidence value.

6 . The method of claim 4 ,
wherein the predefined plurality of fields comprises one or more alphanumeric fields, and wherein comparing the corresponding values of the first set and of the respective second set comprises determining a normalized Levenshtein distance of the corresponding values.

7 . The method of claim 4 ,
wherein the predefined plurality of fields comprises one or more temporal fields, and wherein comparing the corresponding values of the first set and of the respective second set comprises applying a step-wise function to determine a likelihood of the corresponding values being associated with a same event.

8 . A computer program product comprising:
a computer-readable storage medium having computer-readable program code embodied therewith, the computer-readable program code executable by one or more computer processors to perform an operation comprising: receiving, from a first data source, information for a flight object comprising a first set of fields and corresponding values that describe a first flight; retrieving one or more global identifier records from a database, each global identifier record comprising a unique global identifier for a respective flight and a respective second set of fields and corresponding values of the database that describe the respective flight; calculating, based on a comparison of the first set with some or all of the one or more respective second sets, a respective confidence value for each pairing of the flight object with a respective one of the one or more global identifier records; and updating, when a calculated confidence value exceeds a threshold value, the global identifier record corresponding to the calculated confidence value using information from the first set.

9 . The computer program product of claim 8 , the operation further comprising:
determining whether the information for the flight object was previously recorded in a first table of the database corresponding to the first data source; and when the information for the flight object was not previously recorded, recording the information for the flight object in the first table.

10 . The computer program product of claim 8 , the operation, further comprising:
receiving, from a second data source, information for a second flight object corresponding to the first flight; recording information for the second flight object in a second table of the database corresponding to the second data source; and updating the global identifier record corresponding to the first flight using the information for the second flight object.

11 . The computer program product of claim 8 , wherein calculating the respective confidence value for each pairing comprises:
initializing the confidence value to an initial value; comparing, for each field of a predefined plurality of fields, the corresponding values of the first set and of the respective second set for the field; and updating the confidence value based on the comparisons.

12 . The computer program product of claim 11 , the operation further comprising:
determining, for at least one field of the predefined plurality of fields, one or both of the first set and the respective second set do not include a value for the field; and applying, for the at least one field, a predefined penalty factor to the confidence value.

13 . The computer program product of claim 11 ,
wherein the predefined plurality of fields comprises one or more alphanumeric fields, and wherein comparing the corresponding values of the first set and of the respective second set comprises determining a normalized Levenshtein distance of the corresponding values.

14 . The computer program product of claim 11 ,
wherein the predefined plurality of fields comprises one or more temporal fields, and wherein comparing the corresponding values of the first set and of the respective second set comprises applying a step-wise function to determine a likelihood of the corresponding values being associated with a same event.

15 . A system comprising:
one or more processors; and a memory storing instructions that when executed by the one or more processors enable performance of an operation comprising: receiving, from a first data source, information for a flight object comprising a first set of fields and corresponding values that describe a first flight; retrieving one or more global identifier records from a database, each global identifier record comprising a unique global identifier for a respective flight and a respective second set of fields and corresponding values of the database that describe the respective flight; calculating, based on a comparison of the first set with some or all of the one or more respective second sets, a respective confidence value for each pairing of the flight object with a respective one of the one or more global identifier records; and updating, when a calculated confidence value exceeds a threshold value, the global identifier record corresponding to the calculated confidence value using information from the first set.

16 . The system of claim 15 , the operation further comprising:
determining whether the information for the flight obj
