Abstract

Methods and apparatus, including computer program products, implementing and using techniques for providing a web service agent application. The web service agent application has a communication module and a processing module. The communication module receives requests from one or more web service applications or one or more adaptive agent applications; and transmits responses to one or more web service applications or one or more adaptive agent applications. The processing module receives a request for information from the communication module; identifies a resource that can fulfill the request for information; obtains a response to the request from the identified resource; and delivers the response to the request to the communication module.

Claims

1. A web service agent application tangibly embodied in a machine readable storage medium, comprising:

a communication module coupled with a plurality of applications including one or more adaptive agent applications and one or more web service applications, the communication module being operable to;

receive a request for information from a requesting application, wherein the requesting application may be any one of the plurality of applications; and

transmit a response to the requesting application; and

a processing module operable to;

receive a request for information from the communication module;

compare one of the plurality of applications to attempt to match the request based on a preference profile and automatically search for an external application to service the request in response to a match not being made among one of the plurality of applications based on the preference profile;

select an application to provide a resource that can fulfill the request;

obtain a response to the request from the resource; and

deliver the response to the request to the communication module.

2. The web service agent application of claim 1, wherein at least one of the plurality of applications is internal to a local area network.

3. The web service agent application of claim 1, wherein at least one of the plurality of applications is external to a local area network.

4. The web service agent application of claim 1, wherein at least one of the plurality of applications is internal to a local area network;

and at least one of the plurality of applications is external to the local area network.

5. The web service agent application of claim 1, wherein the communication module is further operable to:

automatically interpret a semantic of a web service application; and

publish a service offered by the web service application in a directory that is accessible to one or more web service agent application.

6. The web service agent application of claim 5, wherein the communication module is operable to automatically interpret the semantic by translating terms in a request for web service into terms used by the web service application providing the requested web service to describe its services.

7. The web service agent application of claim 5, wherein the communication module is operable to automatically interpret the semantic of the web service application by interpreting a meaning of terms used by the web service application to describe its services.

8. The web service agent application of claim 1, wherein the processing module is further operable to:

make only selected information available in response to the request for information.

9. The web service agent application of claim 8, wherein the selected information is made available based on a predefined information policy for a web service application or an adaptive agent application requesting information.

10. The web service agent application of claim 8, wherein the processing module further is operable to:

negotiate a set of terms for a fulfillment of the request for information between the requesting application and a resource, based on a predefined negotiation protocol.

11. The web service agent application of claim 10, wherein the set of terms for the fulfillment include a monetary compensation to be paid by a host of the requesting application to a host of the resource.

12. The web service agent application of claim 1, wherein the processing module further is operable to:

evaluate a performance of the one or more web service applications; and

select the responding application based on the evaluation.

13. The web service agent application of claim 1, wherein the processing module further is operable to:

save information regarding a performance of the web service application; and

use the saved in formation to select a responding application.

14. A system, comprising:

one or more servers located in one or more local area networks comprising one or more web service applications;

one or more adaptive agent applications that reside on the one or more servers located in the one or more local area networks; and

one or more web service agents that reside on the one or more servers located in the one or more local area networks, the one or more web service agents coupled with a plurality of applications including the one or more adaptive agent applications and the one or more web service applications, the one or more web service agents being operable to;

receive a request from a requesting application, wherein the requesting application may be any one of the plurality of applications that resides on the one or more local area networks;

compare one of the plurality of applications to attempt to determine a match for the request with one of the plurality of applications based on a preference profile and automatically search to determine the match based on an external application to service the request in response to the match not being determined among one of the plurality of applications based on the preference profile;

select an application based on the match to provide a resource that can fulfill the request, wherein the application resides externally to the one or more local area networks; and

negotiate a set of terms for a response between the requesting application and the application that was selected.

15. A computer-implemented method, comprising:

receiving a request for information from a requesting application, wherein the requesting application is either a web service application or an adaptive agent application;

identifying a resource that can fulfill the request by attempting to match the request with one of a plurality of resources based on a preference profile and automatically searching for an external resource to service the request in response to a match not being made based on the preference profile;

obtaining a response to the request from an identified resource; and

transmitting the response to the requesting application.

16. The method of claim 15, wherein receiving a request comprises:

receiving a request from the requesting application internal to the local area network.

17. The method of claim 15, wherein receiving a request from the requesting application external to a local area network.

18. The method of claim 15, further comprising:

automatically interpreting a semantic of the web service application; and

publishing a service offered by the web service application in a directory that is accessible to one or more web service agent applications.

19. The method of claim 18, wherein automatically interpreting comprises:

translating terms in a request for web service into terms used by the web service application providing the requested service to describe its services.

20. The method of claim 18, wherein automatically interpreting comprises:

interpreting a meaning of terms used by the web service application to describe its services.

21. The method of claim 15, further comprising:

making only selected information available in response to the request for information.

22. The method of claim 21, wherein making selected information available comprises:

making selected information available based on a predefined information policy for the requesting application.

23. The method of claim 22, further comprising:

negotiating a set of terms for a fulfillment of the request for information between the requesting application and the resource, based on a predefined negotiation protocol.

24. The method of claim 23, wherein negotiating comprises:

negotiating a monetary compensation to be paid by a host of the requesting application to a host of the resource.

25. The method of claim 15, further comprising:

evaluating a performance of one or more web service applications;

selecting a responding web service application based on the evaluation.

26. The method of claim 15, further comprising:

saving information regarding a performance of one or more web service applications; and

using the saved information to select a responding web service application.
