Abstract

A method, system, and computer program product for using a federated ontology as an index to enterprise knowledge are provided. The method includes receiving a request for the enterprise knowledge, mapping the request to a concept within the federated ontology, and searching the federated ontology for the concept to identify one or more data sources holding the enterprise knowledge. The method further includes retrieving the enterprise knowledge from the identified one or more data sources as search result data, and returning the search result data.

Claims

1. A method for using a federated ontology as an index to business enterprise knowledge, comprising:

receiving a request for the business enterprise knowledge;

mapping the request to a concept within the federated ontology, wherein the federated ontology comprises a plurality of localized ontologies that are linked through one or more concepts;

searching the federated ontology for the concept to identify one or more data sources holding the business enterprise knowledge;

retrieving the business enterprise knowledge from the identified one or more data sources as search result data; and

returning the search result data.

2. The method of claim 1, wherein the request for the business enterprise knowledge is formatted as a question inquiring about the business enterprise knowledge, and further comprising formatting the search result data as an answer to the question.

3. The method of claim 1, wherein the federated ontology is comprised of a first localized ontology linked with a second localized ontology through a common concept contained within each of the first and second localized ontologies.

4. The method of claim 3, wherein access to the business enterprise knowledge contained within the first and second localized ontologies is controlled based upon permissions or security clearance of each user requesting the business enterprise knowledge.

5. The method of claim 3, wherein the first localized ontology models concepts linked by at least one relationship for a product as assembled and the second localized ontology models concepts linked by at least one relationship for the product as marketed.

6. The method of claim 5, wherein the product is a vehicle.

7. The method of claim 3, wherein at least one of the first and second localized ontologies includes information related to warranty claims.

8. The method of claim 7 further comprising:

tracing the warranty claims for a part;

calculating a cost of the warranty claims for the part; and

reporting the calculated cost of the warranty claims on a per supplier basis.

9. The method of claim 1 further comprising:

semantically tagging data within the one or more data sources holding the business enterprise knowledge; and

linking the semantic data tags to the federated ontology.

10. The method of claim 1 further comprising:

reporting an information path to the business enterprise knowledge from the identified one or more data sources.

11. The method of claim 1, wherein the federated ontology includes information related to a vehicle, parts incorporated in the vehicle, warranty claims for the vehicle, suppliers of the parts, and an assembly plant that assembled the parts into the vehicle.

12. A method for using a federated ontology as an index to enterprise knowledge, comprising:

receiving a request for the enterprise knowledge;

mapping the request to a concept within the federated ontology;

searching the federated ontology for the concept to identify one or more data sources holding the enterprise knowledge;

retrieving the enterprise knowledge from the identified one or more data sources as search result data; and

returning the search result data;

establishing a notification threshold value for the search result data;

initiating the request;

notifying a user when a value in the search result data exceeds the notification threshold value; and

periodically reinitiating the request at a specified interval.

13. A system for using a federated ontology as an index to business enterprise knowledge, comprising:

a host system;

one or more storage devices in communication with the host system, the one or more storage devices holding data sources of the business enterprise knowledge;

a federated ontology accessible via a host system, wherein the federated ontology comprises a plurality of localized ontologies that are linked through one or more concepts; and

a semantic router application executing on the host system, the semantic router application including computer instructions for performing;

receiving a request for the business enterprise knowledge;

mapping the request to a concept within the federated ontology;

searching the federated ontology for the concept to identify the one or more data sources holding the business enterprise knowledge;

retrieving the business enterprise knowledge from the identified one or more data sources as search result data; and

returning the search result data.

14. The system of claim 13, wherein the request for the business enterprise knowledge is formatted as a question inquiring about the enterprise knowledge, and the semantic router application further performs:

formatting the search result data as an answer to the question.

15. The system of claim 13, wherein the federated ontology is comprised of a first localized ontology linked with a second localized ontology through a common concept contained within each of the first and second localized ontologies.

16. The system of claim 15, wherein at least one of the first and second localized ontologies includes information related to vehicle warranty claims.

17. The system of claim 16, wherein the semantic router application further includes computer instructions for performing:

tracing the vehicle warranty claims for a vehicle part;

calculating a cost of the vehicle warranty claims for the vehicle part; and

reporting the calculated cost of the vehicle warranty claims on a per supplier basis.

19. The system of claim 13, wherein the semantic router application further includes computer instructions for performing:

reporting an information path to the business enterprise knowledge from the identified one or more data sources.

18. A system for using a federated ontology as an index to enterprise knowledge, comprising:

a host system;

one or more storage devices in communication with the host system, the one or more storage devices holding data sources of the enterprise knowledge;

a federated ontology accessible via a host system; and

a semantic router application executing on the host system, the semantic router application including computer instructions for performing;

receiving a request for the enterprise knowledge;

mapping the request to a concept within the federated ontology;

searching the federated ontology for the concept to identify the one or more data sources holding the enterprise knowledge;

retrieving the enterprise knowledge from the identified one or more data sources as search result data; and

returning the search result data; and

an agent application executing on the host system, the agent application including computer instructions for performing;

establishing a notification threshold value for the search result data;

initiating the request to the semantic router application;

notifying a user when a value in the search result data exceeds the notification threshold value; and

periodically reinitiating the request to the semantic router application at a specified interval.

20. A computer program product for using a federated ontology as an index to business enterprise knowledge, the computer program product comprising:

a storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for implementing a method, the method comprising;

receiving a request for the enterprise knowledge, wherein the request for the enterprise knowledge is formatted as a question inquiring about the business enterprise knowledge;

mapping the request to a concept within the federated ontology, wherein the federated ontology is comprised of a first localized ontology linked with a second localized ontology through a common concept contained within each of the first and second localized ontologies;

searching the federated ontology for the concept to identify one or more data sources holding the business enterprise knowledge;

retrieving the business enterprise knowledge from the identified one or more data sources as search result data;

formatting the search result data as an answer to the question; and

returning the search result data formatted as the answer to the question.
