Abstract

A method for classifying electronic content is discussed. The method includes obtaining an electronic document from a computing system, identifying one or more document features of the electronic document, analyzing the identified document features to determine a format of electronic content contained in the electronic document (the determined format being implied by one or more indicators provided by the identified document features), and specifying whether the electronic content contained in the electronic document may be displayed on an identified type of computing device, based on the determined format.

Claims

1. A method for classifying electronic content, the method comprising:

obtaining an electronic document from a computing system;

identifying one or more document features of the electronic document;

analyzing the identified document features to determine a format of electronic content contained in the electronic document, the determined format being implied by one or more indicators provided by the identified document features; and

specifying whether the electronic content contained in the electronic document may be displayed on an identified type of computing device, based on the determined format.

2. The method of claim 1, wherein specifying whether the electronic content contained in the electronic document may be displayed on an identified type of computing device comprises analyzing content-based document features.

3. The method of claim 1, wherein the identified document features are analyzed by a machine learning system.

4. The method of claim 1, further comprising:

determining whether to insert an indexed entry associated with the electronic document into a searchable index based upon a level of confidence that the electronic content contained in the electronic document is displayable on the predetermined type of computing device.

5. The method of claim 4, wherein the indexed entry indicates the determined format of the electronic document.

6. The method of claim 1, wherein the electronic content contained in the electronic document comprises displayable web content.

7. The method of claim 1, wherein at least one document feature of the electronic document comprises a tagged feature that may be interpreted for display of electronic content on a computing device.

8. The method of claim 1, wherein analyzing the identified document features comprises applying a predetermined ruleset to the identified document features.

9. The method of claim 8, wherein the predetermined ruleset applies one or more decisions to a plurality of document features.

10. The method of claim 1, wherein specifying whether the electronic content contained in the electronic document may be displayed on an identified type of computing device comprises applying one or more heuristic rules to the determined format and the identified document features.

11. The method of claim 1, wherein specifying whether the electronic content contained in the electronic document may be displayed on an identified type of computing device comprises calculating a confidence rating that is based on a determined level of confidence that the electronic content contained in the electronic document is displayable on the identified type of computing device.

12. The method of claim 11, further comprising:

creating an indexed entry associated with the electronic document, the indexed entry indicating whether the electronic content contained in the electronic document may be displayed on the identified type of computing device; and

inserting the indexed entry into a searchable index, the indexed entry being ranked within the searchable index.

13. The method of claim 1, wherein the identified type of computing device comprises a computing device that is capable of displaying electronic content having one or more predetermined formats.

14. The method of claim 13, wherein the computing device comprises a wireless device.

15. The method of claim 1, wherein the identified type of computing device comprises a predetermined brand or model of computing device.

16. The method of claim 1, wherein the determined format is selected from a group consisting of an XHTML (Extensible Hypertext Markup Language) format, an HTML (Hypertext Markup Language) format, a WML (Wireless Markup Language) format, and a cHTML (compact HTML) format.

17. A computer program product tangibly embodied in an information carrier, the computer program product including instructions that, when executed, perform a method for classifying electronic content, the method comprising:

obtaining an electronic document that is stored in a computing system, the electronic document having electronic content;

parsing the electronic document and identifying one or more document features of the electronic document;

analyzing the identified document features to determine a format of the electronic content contained in the electronic document, the determined format being based upon one or more indicators provided by the identified document features; and

based upon the determined format and the identified document features, specifying whether the electronic content contained in the electronic document may be displayed on a predetermined type of computing device.

18. A system for classifying electronic content, the system comprising:

means for receiving an electronic document;

means for determining a format of electronic content contained in the electronic document; and

means for specifying whether the electronic content contained in the electronic document may be displayed on a predetermined type of computing device based upon the determined format.

19. A method for classifying electronic content, the method comprising:

obtaining an electronic document from a computing system;

identifying a document type for the document using an explicit document type identifier associated with the document;

analyzing one or more document features and the identified document type to determine a format of electronic content contained in the electronic document, the determined format being implied by one or more indicators provided by the identified document features; and

based upon the determined format, specifying whether the electronic content contained in the electronic document may be displayed on an identified type of computing device.

20. A method for classifying electronic content, the method comprising:

obtaining from a computing system an electronic document having electronic content;

identifying a plurality of document features of the electronic document;

calculating a document score based on the plurality of document features; and

specifying whether the electronic content contained in the electronic document may be displayed on an identified type of computing device, based on the document score.

21. The method of claim 20, wherein the document features comprise implied document features.

22. The method of claim 21, wherein the document features comprise content-based document features.
