Abstract

A method for providing contextual support for a publish-subscribe system includes the steps of receiving a user-defined objective of subscription relating to a topic provided from a subscriber to the publish-subscribe system, and determining one or more topics related to the subscriber provided objective of subscription. The method also includes the steps of filtering through a plurality of feeds related to the subscriber provided objective of subscription fed to the publish-subscribe system from one or more feed sources to provide a filtered list of feeds, aggregating through the filtered list of feeds to provide an aggregated list of feeds, and inferencing through the aggregated list of feeds to determine one or more of the plurality feeds that are relevant to the subscriber provided objective of subscription.

Claims

1. A method for providing contextual support for a publish-subscribe system, the method comprising the steps of:

receiving a user-defined objective of subscription relating to a topic provided from a subscriber to the publish-subscribe system;

determining one or more topics related to the subscriber provided objective of subscription;

filtering through a plurality of feeds related to the subscriber provided objective of subscription fed to the publish-subscribe system from one or more feed sources to provide a filtered list of feeds;

aggregating through the filtered list of feeds to provide an aggregated list of feeds; and

inferencing through the aggregated list of feeds to determine one or more of the plurality feeds that are relevant to the subscriber provided objective of subscription.

2. The method of claim 1, wherein the publish-subscribe system comprises a Really Simple syndication system.

3. The method of claim 1, wherein the step of determining one or more topics related to the subscriber provided objective of subscription includes having an ontology engine determine the one or more topics related to the subscriber provided objective of subscription.

4. The method of claim 3, wherein the step of having the ontology engine determine the one or more topics related to the subscriber provided objective of subscription includes identifying semantics of the subscriber provided objective of subscription and determining the one or more topics related to the subscriber provided objective of subscription based on the identified semantics of the subscriber provided objective of subscription.

5. The method of claim 1, further comprising the step of providing a report that includes recommendations based on a result of the step of inferencing through the aggregated list of feeds to determine one or more of the plurality of feeds that are relevant to the subscriber provided objective of subscription.

6. The method of claim 1, further comprising the step of providing each of the plurality of feeds with one or more domain-specific tags related to information associated with each of the plurality of feeds.

7. The method of claim 1, wherein the step of receiving a user-defined objective of subscription relating to a topic provided from a subscriber to the publish-subscribe system includes the step of receiving a user-defined query related to the subscriber provided objective of subscription.

8. A computer program product for providing contextual support for a publish-subscribe system, the computer program product comprising:

a computer readable storage medium having computer readable program code embodied therewith, the computer readable program code comprising;

computer readable program code configured to implement a method for providing contextual support for a publish-subscribe system, the method further including the steps of

receiving a user-defined objective of subscription relating to a topic provided from a subscriber to the publish-subscribe system;

determining one or more topics related to the subscriber provided objective of subscription;

filtering through a plurality of feeds related to the subscriber provided objective of subscription fed to the publish-subscribe system from one or more feed sources to provide a filtered list of feeds;

aggregating through the filtered list of feeds to provide an aggregated list of feeds; and

inferencing through the aggregated list of feeds to determine one or more of the plurality feeds that are relevant to the subscriber provided objective of subscription.

9. The computer program product of claim 8, wherein the publish-subscribe system comprises a Really Simple syndication system.

10. The computer program product of claim 8, wherein the step of determining one or more topics related to the subscriber provided objective of subscription includes having an ontology engine determine the one or more topics related to the subscriber provided objective of subscription.

11. The computer program product of claim 10, wherein the step of having the ontology engine determine the one or more topics related to the subscriber provided objective of subscription includes identifying semantics of the subscriber provided objective of subscription and determining the one or more topics related to the subscriber provided objective of subscription based on the identified semantics of the subscriber provided objective of subscription.

12. The computer program product of claim 8, further comprising the step of providing a report that includes recommendations based on a result of the step of inferencing through the aggregated list of feeds to determine one or more of the plurality of feeds that are relevant to the subscriber provided objective of subscription.

13. The computer program product of claim 8, further comprising the step of providing each of the plurality of feeds with one or more domain-specific tags related to information associated with each of the plurality of feeds.

14. The computer program product of claim 8, wherein the step of receiving a user-defined objective of subscription relating to a topic provided from a subscriber to the publish-subscribe system includes the step of receiving a user-defined query related to the subscriber provided objective of subscription.

15. A system, comprising:

a computing network including a processing device in communication with one or more computer memory storage devices; and

the computing network further configured to implement a method for providing contextual support for a publish-subscribe system, the method further including the steps of

receiving a user-defined objective of subscription relating to a topic provided from a subscriber to the publish-subscribe system;

determining one or more topics related to the subscriber provided objective of subscription;

filtering through a plurality of feeds related to the subscriber provided objective of subscription fed to the publish-subscribe system from one or more feed sources to provide a filtered list of feeds;

aggregating through the filtered list of feeds to provide an aggregated list of feeds; and

inferencing through the aggregated list of feeds to determine one or more of the plurality feeds that are relevant to the subscriber provided objective of subscription.

16. The system of claim 15, wherein the publish-subscribe system comprises a Really Simple syndication system.

17. The system of claim 15, wherein the step of determining one or more topics related to the subscriber provided objective of subscription includes having an ontology engine determine the one or more topics related to the subscriber provided objective of subscription.

18. The system of claim 17, wherein the step of having the ontology engine determine the one or more topics related to the subscriber provided objective of subscription includes identifying semantics of the subscriber provided objective of subscription and determining the one or more topics related to the subscriber provided objective of subscription based on the identified semantics of the subscriber provided objective of subscription.

19. The system of claim 15, further comprising the step of providing a report that includes recommendations based on a result of the step of inferencing through the aggregated list of feeds to determine one or more of the plurality of feeds that are relevant to the subscriber provided objective of subscription.

20. The system of claim 15, further comprising the step of providing each of the plurality of feeds with one or more domain-specific tags related to information associated with each of the plurality of feeds.
