Abstract

A system and method identifies structures within a presentation and detects undesired content in those structures. A decision is made whether to remove portions of the presentation containing the undesired content or the entire presentation, based on determining the domination of the undesired content within the structures of the presentation. The presentation can be reconstructed by being rendered without the undesired content or the structures containing the undesired content.

Claims

1. A method for on-line filtering a presentation comprising:

a) identifying a structure in the presentation;

b) detecting an undesired content in said structure;

c) determining a domination of said structure by said undesired content, and

d) disabling a portion of said structure according to a result of said determining.

2. The method of claim 1, wherein said identifying includes locating a beginning and an end of said structure.

3. The method of claim 1, wherein said structure is a list and said identifying includes recognizing repeated form.

4. The method of claim 1, wherein said structure includes at least one item selected from the group consisting of a list, a menu, a question with an answer, a graphic with associated text, a link with associated text, block of text.

5. The method of claim 1, further comprising:

e) distinguishing a substructure in said structure and wherein said undesirable content is within said substructure and wherein said determining includes accounting for a relationship between said substructure and said structure.

6. The method of claim 5, wherein said substructure includes at least one component selected from the group consisting of a question, an answer, a link, text associated to a link, a graphic, text associated with a graphic, a list item, a menu item, a target of a link, a sentence and a paragraph.

7. The method of claim 1, wherein said disabling is unobtrusive.

8. The method of claim 1, further comprising:

e) rebuilding a rebuilt presentation including an outcome of said disabling.

9. The method of claim 8, wherein said rebuilding retains a white space from said presentation in said rebuilt presentation.

10. The method of claim 8, wherein said identifying includes recognizing an improper form and said rebuilding retaining said improper form.

11. The method of claim 1, wherein the presentation includes a plurality of structures and said steps of determining and disabling are applied to each of at least two structures from said plurality of structures.

12. The method of claim 11, wherein said step of disabling is applied to all of said plurality of structures.

13. A system for removing an undesired content from a presentation stored on an electronically accessible memory comprising:

a) a memory configured for storing;

i) a first database of information on a structure of the presentation, and

ii) a second database configured for storing data on the undesired content, and

b) a processor configured for;

i) identifying said structure;

ii) detecting the undesired content in said structure;

iii) determining a domination of said structure by the undesired content, and

iv) disabling a portion of said structure according to a result of said determining.

14. The system of claim 13, wherein said processor is further configured for:

v) locating a beginning and an end of said structure.

15. The system of claim 13, wherein said processor is further configured for:

v) recognizing a repeated form in a list.

16. The system of claim 13, wherein said processor is further configured for:

v) distinguishing a substructure in said structure and wherein the undesired content is within said substructure and wherein said determining includes accounting for a relationship between said substructure and said structure.

17. The system of claim 13, wherein said processor is further configured for:

v) performing said disabling unobtrusively.

18. The system of claim 13, wherein said processor is further configured for:

v) rebuilding a rebuilt presentation including a result of said disabling.

19. The system of claim 18, wherein said processor of further configured for

vi) retaining a white space from the presentation in said rebuilt presentation.

20. The system of claim 18, wherein said processor is further configured for:

vi) retaining an improper form from the presentation in said rebuilt presentation.

21. The system of claim 13, further comprising:

c) an output device for displaying said rebuilt presentation to a viewer.
