Abstract

The present application discloses methods and systems for configuring and managing class-based condensation. One aspect thereof includes an automated mechanism to receive a user request for a document, retrieve the document from a content server, and compare the document to a base file of a document class. If a delta-difference between the requested document and the base file is less than a predetermined threshold value, create a condensed document by abbreviating redundancy in the requested document relative to the base file of the associated document class, associate the document with the document class, and transmit the condensed document to the user. The documents within a document class possess similar layouts.

Claims

1. A system comprising:

at least one processor;

a receiving module to receive a user request for a requested document;

a condenser executed at least in part by the at least one processor to;

retrieve the requested document from a content server,

compare the requested document to a base file of a document class, wherein documents within the document class possess similar layouts, and

associate the requested document with the document class based on a delta-difference between the requested document and the base file of the document class, in an automated manner; and

a condensed document creator executed at least in part by the at least one processor to create a condensed document by abbreviating redundancy in the requested document relative to the base file of the document class.

2. The system of claim 1, further comprising a transmitting module to transmit the condensed document to a user computer system.

3. The system of claim 1, wherein the condenser is to:

determine that the requested document is not associated with any document class; and

associate the requested document with the document class.

4. The system of claim 1, wherein the condenser is to:

determine that the requested document is not associated with any document class;

generate the document class; and

associate the requested document with the document class.

5. The system of claim 1, wherein the delta-difference is a byte size of the condensed document.

6. The system of claim 1, wherein the base file of the document class is selected from a randomly chosen sample of requested documents within the document class.

7. The system of claim 1, wherein the base file of the document class is created based on aggregated popular components of requested documents within the document class.

8. The system of claim 1, wherein the requested document is a dynamic template-based electronic document.

9. The system of claim 1, wherein the condenser is located between a user computer system and the content server.

10. The system of claim 1, comprising a new document class creator to:

determine that the delta-difference between time requested document and the base file is greater than a determinable threshold value; and

create a new document class associated with the requested document.

11. The system of claim 1, wherein the condenser is to associate the requested document with the document class if the delta-difference between the requested document and the base file of the document class is less than a determinable threshold value.

12. The system of claim 1, wherein the condenser is to associate the requested document with the document classes if the base file of the document class has the lowest delta-difference with the requested document.

13. The system of claim 1, comprising creator module to create the base file of the document class, the creator module being to:

compare components of the base file components of a plurality of requested documents, the plurality of requested documents associated with requests originated from different users; and

determine a component associated with the base file indicative of private information, based on a result of the comparison; and

remove the component indicative of private information from the base file.

14. The system of claim 1, comprising a creator module to create the base file of the document class, the creator module being to:

compare delta-differences between a group of sample documents belonging to the document class;

summing the delta-difference for each of the sample documents of the group; and

selecting the base file from the sample documents, wherein the base file has the lowest sum of delta-differences.

15. The system of claim 14, wherein the creator module is to replace at least one of the sample documents to update the group of sample documents.

16. The system of claim 14, wherein the creator module is to replace at least one of the sample documents with a requested document specified by a user.

17. The system of claim 14, wherein the creator module is to update the group of sample documents periodically.

19. The machine-readable medium of claim 13, having instruction data to cause a machine to transmit the condensed document to a user computer system.

18. A machine-readable medium having instruction data to cause a machine to:

receive a user request for a requested document;

retrieve the requested document from a content server;

compare the requested document to a base file of a document class, wherein documents within the document class possess similar layouts;

associate the requested document with the document class based on a delta-difference between the requested document and the base file of the document class, in an automated manner; and

create a condensed document by abbreviating redundancy in the requested document relative to the base file of the document class.

20. A system comprising:

at least one processor;

means for receiving a user request for a requested document;

means for retrieving the requested document from a content server;

means for comparing the requested document to a base file of a document class, wherein documents within the document class possess similar layouts, the means for comparing being executed at least in part by the at least one processor;

means for associating the requested document with the document class based on a delta-difference between the requested documents and the base file of the documents class, in an automated manner; and

means for creating a condensed document by abbreviating redundancy in the requested document relative to the base file of the document class, the means for creating the condensed document being executed at least in part by the at least one processor.
