Abstract

A system and method for automatically generating the most relevant thumbnail of a document. Every page of a multi-page document is analyzed for rich content. Based on this analysis, a score is assigned to every page of the document depending on certain parameters such as the amount of rich content and number of occurrences of rich content on each page. The page with the highest score is identified and this page is selected as the thumbnail of the document.

Claims

1. A computer-implemented method, comprising:

analyzing a plurality of pages of a multi-page document to identify quantity and type of rich content in each one of the plurality of pages;

assigning a score to each one of the plurality of pages in the multi-page document, wherein the score for a respective one of the plurality of pages is dependent on the quantity of rich content items on the respective one of the plurality of pages and the type of each rich content item on the respective one of the plurality of pages, wherein said assigning comprises scoring each page based on the quantity and type of rich content items within that page;

identifying a page of the plurality of pages with the highest score; and

designating the page with the highest score to be displayed as a thumbnail of the multi-page document, wherein the thumbnail is a single visual representation for the multi-page document.

2. The method of claim 1, further comprising:

generating the thumbnail of the multi-page document from the designated page;

storing the thumbnail of the multi-page document; and

in response to user input, retrieving the thumbnail of the multi-page document.

3. The method of claim 1, further comprising:

tagging the designated page;

sending the designated page to an asset management system to represent the multi-page document using the designated page.

4. The method of claim 1, further comprising displaying said thumbnail of the designated page of the multi-page document.

5. The method of claim 1, wherein said analyzing comprises determining an amount of rich content on each of the plurality of pages.

6. The method of claim 1, wherein said analyzing comprises counting a number of occurrences of rich content on each of the plurality of pages.

7. The method of claim 1, wherein said rich content comprises one or more of an image, a comment, a video, a graphic, audio, a table, or text with styling.

8. The method of claim 1, wherein said analyzing, said assigning, said identifying and said designating are performed in response to presentation of the multi-page document for viewing.

9. A computer-implemented method of selecting content for use as a thumbnail from a multi-page document, comprising:

analyzing a plurality of pages of the multi-page document to identify quantity and type of rich content in each one of the plurality of pages;

assigning each one of the plurality of pages a score, wherein the score for a respective one of the plurality of pages is dependent on the quantity of rich content items on the respective one of the plurality of pages and the type of each rich content item on the respective one of the plurality of pages, wherein said assigning comprises scoring each page based on the quantity and type of rich content items within that page;

identifying a subset of the plurality of pages of the multi-page document, wherein the identified subset is less than all of the plurality of pages of the multi-page document, and wherein each page in the identified subset has a highest score; and

designating the identified subset of the plurality of pages to be displayed as the thumbnail of the multi-page document, wherein the thumbnail is a single visual representation for the multi-page document.

10. The method of claim 9, wherein said analyzing comprises determining an amount of rich content on each one of the plurality of pages.

11. The method of claim 9, wherein said analyzing comprises counting a number of occurrences of rich content on each one of the plurality of pages.

12. The method of claim 9, wherein the thumbnail comprises a collage, and wherein the collage comprises the identified subset of the plurality of pages.

13. The method of claim 9, wherein said rich content comprises one or more of an image, a comment, video, a graphic, audio, a table, or text with styling.

14. A machine-readable storage device storing instructions executable by a processor to:

analyze a plurality of pages of a multi-page document to identify quantity and type of rich content in each one of the plurality of pages;

assign a score to each one of the plurality of pages in the multi-page document, wherein the score for a respective one of the plurality of pages is dependent on the quantity of rich content items on the respective one of the plurality of pages and the type of each rich content item on the respective one of the plurality of pages, wherein said assigning comprises scoring each page based on the quantity and type of rich content items within that page;

identify a page of the plurality of pages with the highest score; and

designate the page with the highest score to be displayed as a thumbnail of the multi-page document, wherein the thumbnail is a single visual representation.

15. The machine-readable storage device of claim 14, wherein said analyzing a plurality of pages comprises determining an amount of rich content on each one of the plurality of pages.

16. The machine-readable storage device of claim 14, wherein said analyzing comprises counting a number of occurrences of rich content on each one of the plurality of pages.

17. The machine-readable storage device of claim 14, wherein said rich content comprises one or more of an image, a comment, video, a graphic, audio, a table, or text with styling.

18. A machine-readable storage device storing instructions operable to cause a programmable processor to:

analyze a plurality of pages of a multi-page document to identify quantity and type of rich content in each one of the plurality of pages;

assign a score to each one of the plurality of pages in the multi-page document, wherein the score for a respective one of the plurality of pages is dependent on the quantity of rich content items on the respective one of the plurality of pages and the type of each rich content item on the respective one of the plurality of pages, wherein said assigning comprises scoring each page based on the quantity and type of rich content items within that page;

identify a subset of the plurality of pages of the multi-page document, wherein the identified subset is less than all of the plurality of pages of the multi-page document, and wherein each page in the identified subset has a highest score; and

designate the identified subset of the plurality of pages to be displayed as a thumbnail of the multi-page document, wherein the thumbnail is a single visual representation for the multi-page document.

19. The machine-readable storage device of claim 18, wherein the thumbnail comprises a collage, and wherein the collage comprises the subset of the plurality of pages.

20. A system, comprising:

a computer configured to implement;

an analyzer module operable to analyze a plurality of pages of a multi-page document to identify quantity and type of rich content in each one of the plurality of pages;

a scoring module operable to assign a score to each one of the plurality of pages in the multi-page document, wherein the score for a respective one of the plurality of pages is dependent on the quantity of rich content items on the respective one of the plurality of pages and the type of each rich content item on the respective one of the plurality of pages, wherein said assigning comprises scoring each page based on the quantity and type of rich content items within that page; and

a thumbnail determination module operable to identify a page of the plurality of pages with a highest score to be displayed as a thumbnail of the multi-page document, wherein the thumbnail is a single visual representation for the multi-page document.

21. The system of claim 20, wherein the computer is further configured to implement:

a database module operable to store page numbers, a list of rich content types and a respective count of a quantity of each rich content type identified on each of the plurality of pages.
