Abstract

Claims (53)

1. A method comprising:

accessing, using a processing unit, a first source chain datafile including data entries identifying linkages between a service provider, a service receiver, and a component provider, of an enterprise, the first source chain datafile covering a first period of time;

forming, using the processing unit, initial knowledge graph tuples including subject, object, and predicate components based on the linkages;

generating, using the processing unit, a staging knowledge graph storing the initial knowledge graph tuples;

translating, using the processing unit, the initial knowledge graph tuples into production knowledge graph tuples according to a source chain knowledge graph schema;

storing, using the processing unit, the production knowledge graph tuples in a production knowledge graph;

ingesting a second source chain datafile covering a second period of time into the production knowledge graph, the second period of time occurring before the first period of time;

inferring, using the production knowledge graph, material entities in the first source chain datafile based on a centrality metric for entities in the first source chain datafile;

inferring, using the production knowledge graph, material entities in the second source chain datafile based on a centrality metric for entities in the second source chain datafile;

executing a first data quality review on tuples in production knowledge graph originating from the first source chain datafile to identify a number of mismatches between service receivers designated as critical and non-material service providers;

executing a second data quality review on tuples in production knowledge graph originating from the second source chain datafile to identify a number of mismatches between service receivers designated as critical and non-material service providers; and

presenting a user interface on a computing device, the user interface including a visualization of a change between a result of the first data quality review and the second data quality review.

2. The method of claim 1 , wherein the source chain knowledge graph schema inherits a second knowledge graph data schema.

3. The method of claim 1 , wherein the first source chain datafile is formatted as a spreadsheet document format having columns and rows.

4. The method of claim 3 , wherein forming the initial knowledge graph tuples including subject, object, and predicate components based on the linkages includes:

generating a plurality of initial knowledge graph tuples from a row in the source chain datafile.

5. The method of claim 1 , wherein mapping, using the processing unit, the initial knowledge graph tuples into production knowledge graph tuples according to a source chain knowledge graph schema includes using a resource description framework to resource description framework process.

6. A non-transitory computer-readable medium comprising instructions, which when executed by a processing unit, configure the processing unit to perform operations comprising:

accessing a first source chain datafile formatted in a first format, the source chain datafile including data entries identifying linkages between a service provider, a service receiver, and a component provider, of an enterprise, the first source chain datafile covering a first period of time;

forming initial knowledge graph tuples including subject, object, and predicate components based on the linkages;

generating a staging knowledge graph storing the initial knowledge graph tuples;

translating the initial knowledge graph tuples into production knowledge graph tuples according to a source chain knowledge graph schema;

storing the production knowledge graph tuples in a production knowledge graph;

ingesting a second source chain datafile covering a second period of time into the production knowledge graph, the second period of time occurring before the first period of time;

inferring, using the production knowledge graph, material entities in the first source chain datafile based on a centrality metric for entities in the first source chain datafile;

inferring, using the production knowledge graph, material entities in the second source chain datafile based on a centrality metric for entities in the second source chain datafile;

executing a first data quality review on tuples in production knowledge graph originating from the first source chain datafile to identify a number of mismatches between service receivers designated as critical and non-material service providers;

executing a second data quality review on tuples in production knowledge graph originating from the second source chain datafile to identify a number of mismatches between service receivers designated as critical and non-material service providers; and

presenting a user interface on a computing device, the user interface including a visualization of a change between a result of the first data quality review and the second data quality review.

7. The non-transitory computer-readable medium of claim 6 , wherein the source chain knowledge graph schema inherits a second knowledge graph data schema.

8. The non-transitory computer-readable medium of claim 6 , wherein the first source chain datafile is formatted as a spreadsheet document format having columns and rows.

9. The non-transitory computer-readable medium of claim 8 , wherein forming the initial knowledge graph tuples including subject, object, and predicate components based on the linkages includes:

generating a plurality of initial knowledge graph tuples from a row in the source chain datafile.

10. The non-transitory computer-readable medium of claim 6 , wherein mapping the initial knowledge graph tuples into production knowledge graph tuples according to a source chain knowledge graph schema includes using a resource description framework to resource description framework process.

11. A system comprising:

a processing unit; and

a storage device comprising instructions, which when executed by the processing unit, configure the processing unit to perform operations comprising:

accessing a first source chain datafile formatted in a first format, the source chain datafile including data entries identifying linkages between a service provider, a service receiver, and a component provider, of an enterprise, the first source chain datafile covering a first period of time;

forming initial knowledge graph tuples including subject, object, and predicate components based on the linkages;

generating a staging knowledge graph storing the initial knowledge graph tuples;

translating the initial knowledge graph tuples into production knowledge graph tuples according to a source chain knowledge graph schema;

storing the production knowledge graph tuples in a production knowledge graph;

ingesting a second source chain datafile covering a second period of time into the production knowledge graph, the second period of time occurring before the first period of time;

inferring, using the production knowledge graph, material entities in the first source chain datafile based on a centrality metric for entities in the first source chain datafile;

inferring, using the production knowledge graph, material entities in the second source chain datafile based on a centrality metric for entities in the second source chain datafile;

executing a first data quality review on tuples in production knowledge graph originating from the first source chain datafile to identify a number of mismatches between service receivers designated as critical and non-material service providers;

executing a second data quality review on tuples in production knowledge graph originating from the second source chain datafile to identify a number of mismatches between service receivers designated as critical and non-material service providers; and

presenting a user interface on a computing device the user interface including a visualization of a change between a result of the first data quality review and the second data quality review.

12. The system of claim 11 , wherein the source chain knowledge graph schema inherits a second knowledge graph data schema.
