Abstract

A computing device is configured to generate a graphical user interface (GUI) that allows an end-user to search for particular document or documents within a large collection of documents. The GUI provides a view of the overall document collection and affords the end-user the ability to reduce the number of visual document thumbnails by means of keyword search. When the end-user identifies a candidate among the reduced number of thumbnails, the end-user may select the page view of the candidate document and conduct further review. If the selected candidate is not the target document, the end-user may select adjacent documents to seamlessly transition between reading and searching. An advantage to this approach is that the visual qualities of the documents, such as images, graphical layout, and color, among others, may be incorporated into the search process. Searching for a particular target document is, thus, expedited.

Claims

1. A computer-implemented method for viewing documents stored in a database, the method comprising:

rendering a first composite image illustrating a graphical overview of the database that includes a plurality of first-sized images that correspond to a plurality of documents;

rendering a second composite image that includes a plurality of second-sized images that correspond to a subset of the plurality of documents;

rendering a third composite image that includes a plurality of variable-sized images that correspond to one or more pages of a first document included in the subset; and

causing a graphical user interface (GUI) to display the first composite image, the second composite image, and the third composite image on a display device.

2. The computer-implemented method of claim 1, wherein each image included in the plurality of first-sized images comprises a thumbnail image that is smaller than a corresponding image included in the plurality of second-sized images.

3. The computer-implemented method of claim 1, wherein each document included in the subset of documents is identified via keyword search term input by a user.

4. The computer-implemented method of claim 1, wherein the third composite image includes a first image having a first resolution that corresponds to a first page of the first document and a second image having a second resolution that corresponds to a second page of the first document, wherein the first resolution exceeds the second resolution.

5. The computer-implemented method of claim 1, wherein the third composite image further includes metadata indicating at least one of a title, an abstract, one or more authors, a venue, and a year, associated with the first document.

6. The computer-implemented method of claim 1, wherein rendering the third composite image comprises:

converting the first document to a set of one-page files;

combining the set of one-page files into a complement of single images; and

compressing the complement of single images to generate a first version of the third composite image.

7. The computer-implemented method of claim 6, further comprising generating a multi-resolution image pyramid that includes the third composite image by:

generating a second version of the third composite image with a second resolution; and

combining the first version of the third composite image and the second version of the third composite image, wherein the first resolution exceeds the second resolution.

8. The computer-implemented method of claim 7, further comprising:

identifying a second document in the second composite image that is adjacent to the first document in the subset of documents; and

rendering a fourth composite image that correspond to the second document.

9. The computer-implemented method of claim 8, further comprising displaying the previously-rendered fourth composite image in response to receiving a selection from the end-user of the second document in the second composite image.

10. A non-transitory computer-readable medium storing program instructions that, when executed by a processing unit, cause the processing unit to facilitate viewing documents stored in a database by performing the steps of:

rendering a first composite image illustrating a graphical overview of the database that includes a plurality of first-sized images that correspond to a plurality of documents;

rendering a second composite image that includes a plurality of second-sized images that correspond to a subset of the plurality of documents;

rendering a third composite image that includes a plurality of variable-sized images that correspond to one or more pages of a first document included in the subset; and

causing a graphical user interface (GUI) to display the first composite image, the second composite image, and the third composite image on a display device.

11. The non-transitory computer-readable medium of claim 10, wherein each image included in the plurality of first-sized images comprises a thumbnail image that is smaller than a corresponding image included in the plurality of second-sized images

12. The non-transitory computer-readable medium of claim 10, wherein each document included in the subset of documents is identified via keyword search term input by a user.

13. The non-transitory computer-readable medium of claim 10, wherein the third composite image includes a first image having a first resolution that corresponds to a first page of the first document and a second image having a second resolution that corresponds to a second page of the first document, wherein the first resolution exceeds the second resolution.

14. The non-transitory computer-readable medium of claim 10, wherein the third composite image further includes metadata indicating at least one of a title, an abstract, one or more authors, a venue, and a year, associated with the first document.

15. The non-transitory computer-readable medium of claim 10, further comprising the steps of:

converting the first document to a set of one-page files;

combining the set of one-page files into a complement of single images; and

compressing the complement of single images to generate a first version of the third composite image.

16. The non-transitory computer-readable medium of claim 15, further comprising the steps of:

generating a second version of the third composite image with a second resolution; and

combining the first version of the third composite image and the second version of the third composite image, wherein the first resolution exceeds the second resolution.

17. A system configured for viewing documents stored in a database, including:

a memory unit;

a processing unit coupled to the memory unit and configured to;

render a first composite image illustrating a graphical overview of the database that includes a plurality of first-sized images that correspond to a plurality of documents;

render a second composite image that includes a plurality of second-sized images that correspond to a subset of the plurality of documents;

render a third composite image that includes a plurality of variable-sized images that correspond to one or more pages of a first document included in the subset; and

cause a graphical user interface (GUI) to display the first composite image, the second composite image, and the third composite image on a display device.

18. The computing device of claim 17, wherein the memory unit stores program instructions that, when executed by the processing unit, cause the processing unit to:

render the first composite image;

render the second composite image;

render the third composite image; and

cause the GUI to display the first composite image, the second composite image, and the third composite image on the display device.

19. The system of claim 17, wherein the processing unit is further configured to:

convert the first document to a set of one-page files;

combine the set of one-page files into a complement of single images; and

compress the complement of single images to generate a first version of the third composite image.

20. The system of claim 19, wherein the processing unit is further configured to:

generate a second version of the third composite image with a second resolution; and

combine the first version of the third composite image and the second version of the third composite image, wherein the first resolution exceeds the second resolution.
