Abstract

A method of combining information from multiple heterogeneous workers comprises transmitting a first search request to a search worker to assist the search worker in searching a first database and returning a first results set. A second search request is directed to a peer worker to assist the peer worker in initiating a search of a second database across a network asynchronously from the search worker and returning a second results set. The first results set and second results set are then incorporated into a composite results set.

Claims

1. A method of combining information from multiple heterogeneous workers, comprising:

transmitting a first search request to a search worker to assist said search worker in searching a first database and returning a first results set;

directing a second search request to a peer worker to assist said peer worker in initiating a search of a second database across a network asynchronously from said search worker and returning a second results set; and

incorporating said first results set and said second results set into a composite results set.

2. The method of claim 1 wherein said transmitting further comprises transmitting said first search request to assist in the returning of a first results set within a data stream including data elements expressing the content of said first data set, and control elements containing instructions for manipulating said data elements.

3. The method of claim 2 further including the steps of retrieving information to supplement one or more of said data elements, and appending said information to said one or more data elements.

4. The method of claim 2 further including the step of replacing one or more of said control elements with one or more of said data elements.

5. The method of claim 2 further including the step of replacing one or more of said control elements with one or more supplementary control elements containing instructions for further manipulating said data elements.

6. The method of claim 1 further including the step of requesting authentication information from a security worker so as to facilitate access to at least one of said first database and said second database.

7. The method of claim 1 wherein said incorporating includes merging said first results set with said second results set.

8. The method of claim 7 wherein said merging includes retrieving supplementary information further detailing said first results set and said second results set, and combining said first results set and said second results set based on said supplementary information.

9. The method of claim 7 wherein said merging includes reordering information within said first results set and said second results set.

10. The method of claim 1 wherein said directing includes directing a second search request to said peer worker to assist said peer worker in initiating a search of a second database within a peer to peer network.

11. The method of claim 1 wherein said transmitting includes relaying said search request to a dispatch worker configured to distribute said search request to said search worker and said peer worker.

12. The method of claim 1 further including the steps of receiving a third results set from said search worker or said peer worker, and incrementally updating said composite results set by combining said third results set and said composite results set.

13. A computer based agent with multiple heterogeneous worker components, comprising:

a search worker configured to receive a search request, conduct a first search according to said search request, and generate a first data set detailing the results of said first search;

a peer worker configured to receive said search request, said communications worker further configured to operate asynchronously from said search worker while transmitting said search request across a network to initiate a second search, and receiving a second data set detailing the results of said second search; and

a module configured to incorporate said first data set and said second data set into a composite data set.

14. The computer based agent of claim 13 further including a security worker configured to retrieve authentication information for obtaining permission to perform at least one of said first search and said second search, and to deliver said authentication information to said search worker and said peer worker.

15. The computer based agent of claim 13 further including a dispatch worker configured to distribute said search request to said search worker and said peer worker.

16. The computer based agent of claim 13 further including a parametric worker configured to modify said first search and said second search according to a specified parameter.

17. The computer based agent of claim 13 wherein said search worker is further configured to communicate said first data set to said module within a data stream including data elements expressing the content of said first data set, and control elements instructing said parent worker to manipulate said data elements.

18. The computer based agent of claim 17 wherein said module is further configured to retrieve information to supplement one or more of said data elements.

19. The computer based agent of claim 17 wherein said module is further configured to replace one or more of said control elements with one or more of said data elements.

20. The computer based agent of claim 17 wherein said module is further configured to replace one or more of said control elements with one or more supplementary control elements containing instructions for further manipulating said data elements.

21. The computer based agent of claim 13 wherein said peer worker is further configured to communicate said second data set to said module within a data stream including data elements expressing the content of said second data set, and control elements instructing said parent worker to manipulate said data elements.

22. The computer based agent of claim 21 wherein said peer worker is further configured to retrieve information to supplement one or more of said data elements, and to append said information to said one or more data elements.

23. The computer based agent of claim 21 wherein said peer worker is further configured to replace one or more of said control elements with one or more of said data elements.

24. The computer based agent of claim 21 wherein said peer worker is further configured to replace one or more of said control elements with one or more supplementary control elements containing instructions for further manipulating said data elements.

25. The computer based agent of claim 13 wherein said peer worker is configured to initiate said second search within a peer to peer network.

26. The computer based agent of claim 13 wherein said module is further configured to combine said first data set and said second data set so as to create said composite data set.

27. The computer based agent of claim 26 wherein said module is further configured to reorder information included within said first data set and said second data set.

28. The computer based agent of claim 13 further including a content fetch module configured to retrieve supplementary information further detailing said first data set and said second data set.

29. The computer based agent of claim 13 further including an output module configured to incorporate said composite data set into instructions written in a computer readable language.

30. The computer based agent of claim 28 further including a personalization worker configured to retrieve format information describing the display of said composite data set, and to instruct said output module to incorporate said composite data set into instructions written according to said format information.

31. The computer based agent of claim 13 further including a cache module configured to store said first data set, said second data set, and said composite data set in a computer memory.
