Abstract

A system for reliably retrieving information which may be in any one of several possible formats and for subsequent display of that information in any one of several possible formats. User-defined agents are used to retrieve target data based on a heuristic algorithm and to store the target data in a canonical form, ready for republication in whatever form best suits a particular application. The system is particularly well suited to obtaining information over the internet for display on a desktop system, but it is also well suited for applications having only limited display or computational capabilities.

Claims

1. Apparatus comprising:

retrieval means for retrieving a first set of data from a first predetermined data source, said first set of data including a second set of data;

6. Apparatus as claimed in claim 5 wherein said retrieval means, said analyzing means, and said storing means all reside and execute on a computer which communicates with said home gate way system over the Internet.

7. Apparatus as claimed in claim 3 wherein said display device is a screen on a web-enabled telephone and wherein said means for recalling is incorporated into said web-enabled telephone.

8. Apparatus as claimed in claim 7 wherein said retrieval means, said analyzing means, and said storing means all reside and execute on a central computer which exchanges data with said web-enabled telephone via a cellular telephone network.

9. Apparatus as claimed in claim 3 wherein said display device is a screen on a PDA.

10. Apparatus as claimed in claim 1 wherein said first predetermined data source includes status information for an external device, and wherein said first set of data includes said status information.

11. Apparatus as claimed in claim 1 wherein said selecting means selects one of said first, second, and third candidates as said second set of data based on a first weighting assigned to said first identifying means, a second weighting assigned to said second identifying means, and a third weighting assigned to said third identifying means.

12. Apparatus as claimed in claim 11 further comprising means, responsive to said selecting means, for altering said first weighting based on a degree of correspondence between said second set of data selected by said selecting means and said first candidate, for altering said second weighting based on a degree of correspondence between said second set of data selected by said selecting means and said second candidate, and for altering said third weighting based on a degree of correspondence between said second set of data selected by said selecting means and said third candidate.

13. Apparatus as claimed in claim 1 wherein said first predetermined data source is a web page.

14. The apparatus of claim 1 wherein said second set of data is similar to said fourth set of data.

15. Apparatus comprising:

retrieval means for retrieving a first set of data from a first predetermined data source and a second set of data from a second predetermined data source, said first set of data and said second set of data each being in any one of several possible formats;

analyzing means for analyzing said first set of data to select, using a first identifying strategy, a second identifying strategy, and a third identifying strategy, a first subset of data included in said first set of data based on a prior analysis of semantics, syntax, or position of said first subset of data included in a previous version of said first set of data, and for analyzing said second set of data to select, using the first identifying strategy, the second identifying strategy, and the third identifying strategy, a second subset of data included in said second set of data based on a prior analysis of semantics, syntax, or position of said second subset of data in a previous version of said second set of data; and

means for displaying said first subset of data and said second subset of data on a display device, said means for displaying including means for reformatting said first subset of data and said second subset of data if necessary for display on said display device.

16. Apparatus as claimed in claim 15, wherein said first predetermined data source is an internet resource.

17. Apparatus as claimed in claim 15 wherein said second predetermined data source is an enterprise intranet resource.

18. Apparatus as claimed in claim 15 wherein said display device is a computer monitor.

19. Apparatus as claimed in claim 15 wherein said display device is a television monitor and wherein said means for displaying is incorporated into a cable set-top box.

21. Apparatus as claimed in claim 15 wherein said display device is a screen on a PDA.

22. Apparatus as claimed in claim 15 further comprising storing means for storing said first subset of data and said second subset of data in a data store in a predefined storage format, said storing means including means for formatting said first subset of data and said second subset of data in said storage format if the format of the first subset of data and said second subset of data is different from said storage format.

23. Apparatus as claimed in claim 15 further comprising a scheduling application for activating said retrieval means at scheduled time intervals.

24. A method comprising the steps of:

retrieving a first set of data from a predetermined data source, said first set of data including a second set of data;

analyzing semantics, syntax, or position of said second set of data within said first set of data;

building an agent, said agent comprising instructions based on said step of analyzing semantics, syntax, or position of said second set of data, wherein said instructions are to be used to subsequently retrieve a third set of data from said first predetermined data source and select a fourth set of data included in said third set of data; and

assigning a first weighting factor to a first strategy for retrieving said third set of data;

assigning a second weighting factor to a second strategy for retrieving said third set of data;

assigning a third weighting factor to a third strategy for retrieving said third set of data;

determining a first candidate for said third set of data using said first strategy, a second candidate using said second strategy, and a third candidate for said third set of data using said third strategy; and

selecting one of said first, second, and third candidates as a result third set of data based on said first, second, and third weighting factors.

25. The method of claim 24, further comprising the step of:

adjusting said first weighting factor based on whether said first candidate matches said result third set of data, said second weighting factor based on whether said second candidate matches said result third set of data, and said third weighting factor based on whether said third candidate matches said result third set of data.
