Determining Most Relevant Data Measurement from Among Competing Data Points
Disclosed herein are techniques for determining a most relevant data measurement from among competing data points. Particular embodiments call for an evaluation engine to receive as input from an underlying database, a plurality of competing data points together with meta-data reflecting a provenance of those data points. The evaluation engine is configured to apply a precedence rule set to the input, and produce an output comprising a most relevant data measurement. Via application of the precedence rule set, the evaluation engine may consider expected reliability of the source of the data measurement. The precedence rule set may also reflect other factors, such as a number of alternative sources for the measurement, a freshness of the measurement, and/or a possibility of combining (e.g. averaging) a plurality of otherwise equally situated measurements. An example evaluates the statistics of pro football prospects (e.g. foot speed) available from different sources (e.g. scouting reports).
1 . A computer-implemented method comprising:
providing an evaluation engine in communication with a database comprising a first data measurement, a first meta-data indicating a first source of the first data measurement, a second data measurement, and a second meta-data indicating a second source of the second data measurement;
causing the evaluation engine to calculate from the first meta-data, a first precedence value for the first data measurement;
causing the evaluation engine to calculate from the second meta-data, a second precedence value for the second data measurement; and
causing the evaluation engine to reference a precedence rule set to determine a relevance of the first data measurement over the second data measurement.
2 . A method as in claim 1 wherein:
the first precedence value is different from the second precedence value; and
the first precedence value indicates a provenance of the first source is greater than a provenance of the second source.
3 . A method as in claim 1 wherein:
the first precedence value is the same as the second precedence value; and
the precedence rule set relies upon a secondary criterion to determine the relevance of the first data measurement over the second data measurement.
4 . A method as in claim 3 wherein the secondary criterion comprises a relative magnitude of the first data measurement versus the second data measurement.
5 . A method as in claim 3 wherein the secondary criterion comprises a freshness of the first data measurement versus the second data measurement.
6 . A method as in claim 1 further comprising causing the evaluation engine to display the first data measurement to a user.
7 . A non-transitory computer readable storage medium embodying a computer program for performing a method, said method comprising:
providing an evaluation engine in communication with a database comprising a first data measurement, a first meta-data indicating a first source of the first data measurement, a second data measurement, and a second meta-data indicating a second source of the second data measurement;
causing the evaluation engine to calculate from the first meta-data, a first precedence value for the first data measurement;
causing the evaluation engine to calculate from the second met-data, a second precedence value for the second data measurement; and
causing the evaluation engine to reference a precedence rule set to determine a relevance of the first data measurement over the second data measurement.
8 . A non-transitory computer readable storage medium as in claim 7 wherein:
the first precedence value is different from the second precedence value; and
the first precedence value indicates a provenance of the first source is greater than a provenance of the second source.
9 . A non-transitory computer readable storage medium as in claim 7 wherein:
the first precedence value is the same as the second precedence value; and
the precedence rule set relies upon a secondary criterion to determine the relevance of the first data measurement over the second data measurement.
10 . A non-transitory computer readable storage medium as in claim 9 wherein the secondary criterion comprises a relative magnitude of the first data measurement versus the second data measurement.
11 . A non-transitory computer readable storage medium as in claim 9 wherein the secondary criterion comprises a freshness of the first data measurement versus the second data measurement.
12 . A non-transitory computer readable storage medium as in claim 7 wherein the method further comprises causing the evaluation engine to display the first data measurement to a user.
13 . A computer system comprising:
one or more processors;
a software program, executable on said computer system, the software program configured to:
provide an evaluation engine in communication with a database comprising a first data measurement, a first meta-data indicating a first source of the first data measurement, a second data measurement, and a second meta-data indicating a second source of the second data measurement;
cause the evaluation engine to calculate from the first meta-data, a first precedence value for the first data measurement;
cause the evaluation engine to calculate from the second meta-data, a second precedence value for the second data measurement; and
cause the evaluation engine to reference a precedence rule set to determine a relevance of the first data measurement over the second data measurement.
14 . A computer system as in claim 13 wherein:
the first precedence value is different from the second precedence value; and
the first precedence value indicates a provenance of the first source is greater than a provenance of the second source.
15 . A computer system as in claim 13 wherein:
the first precedence value is the same as the second precedence value; and
the precedence rule set relies upon a secondary criterion to determine the relevance of the first data measurement over the second data measurement
16 . A computer system as in claim 15 wherein the secondary criterion comprises a relative magnitude of the first data measurement versus the second data measurement.
17 . A computer system as in claim 15 wherein the secondary criterion comprises a freshness of the first data measurement versus the second data measurement.
18 . A computer system as in claim 13 wherein the software program is further configured to causing the evaluation engine to display the first data measurement to a user.
