Abstract

Systems and methods for information capture from articles are described. In one embodiment, a plurality of keystrokes associated with an application is received, each keystroke is processed to determine an associated action forming a plurality of associated actions, and an event is determined based at least in part on the plurality of associated actions.

Claims

1. A computer-implemented method for a capture processor executing on a computer to determine an event associated with an application, comprising:

receiving, with the capture processor, a plurality of keystrokes associated with a first application with focus monitored by the capture processor, the first application with focus comprising an application being used by a user of the computer to enter text;

determining, with the capture processor, that focus has changed from the first application monitored by the capture processor to a second application monitored by the capture processor, wherein focus changes when the user switches from using the first application to using the second application to enter text;

resetting, with the capture processor, the keystrokes received from the first application by clearing the received keystrokes responsive to determining that the focus has changed;

receiving, with the capture processor, a plurality of new keystrokes associated with the second application;

processing, with the capture processor, each new keystroke to determine an associated action in the second application, the plurality of new keystrokes forming a plurality of associated actions;

analyzing, with the capture processor, the plurality of associated actions to determine whether a complete event has occurred in the second application; and

selectively indexing the complete event responsive to determining that the complete event occurred.

2. The method of claim 1, wherein the analyzing determines that a complete event has occurred responsive to the plurality of associated actions indicating that a complete word has been entered into the application.

3. The method of claim 2, wherein the analysis determines that a complete word has been entered responsive to the plurality of associated actions indicating that a space or a punctuation symbol has been entered.

4. The method of claim 1, wherein the analyzing determines that a complete event has occurred responsive to the plurality of associated actions indicating that a predetermined number of characters have been typed into the application.

5. The method of claim 1, further comprising updating, with the capture processor, a capture state after each keystroke is processed.

6. The method of claim 1, further comprising updating, with the capture processor, a current user state based at least in part on the event.

7. The method of claim 1, wherein an associated action comprises one of adding a character to a word, deleting a character from a word, inserting a character, overwriting a character, deleting a word, deleting a paragraph, selecting an item, and repositioning the cursor.

8. The method of claim 1, wherein the associated action is determined based at least in part by matching a keystroke to a keystroke table and wherein the keystroke table is associated with the application and wherein different applications are associated with different keystroke tables.

9. The method of claim 1, wherein the associated action is determined based at least in part by matching a keystroke to a generic keystroke table common to a plurality of applications.

19. The method of claim 1, wherein the analyzing determines that a complete event has occurred responsive to the plurality of associated actions indicating that a predetermined number of words have been typed into the application.

20. The method of claim 1, wherein the resetting the keystrokes captured from the first application comprises saving the keystrokes before clearing the keystrokes.

10. A computer-implemented method for a capture processor executing on a computer to determine and selectively index an event associated with an application, comprising:

receiving, with the capture processor, a plurality of display calls associated with a first application with focus monitored by the capture processor, the first application with focus comprising an application being used by a user of the computer to enter text;

determining, with the capture processor, that focus has changed from the first application monitored by the capture processor to a second application monitored by the capture processor, wherein focus changes when the user switches from using the first application to using the second application to enter text;

resetting, with the capture processor, the display calls received from the first application by clearing the received display calls responsive to determining that the focus has changed;

receiving, with the capture processor, a plurality of new display calls associated with the second application;

processing, with the capture processor, the plurality of new display calls to determine a display produced by the second application;

analyzing, with the capture processor, the display produced by the second application to determine whether a complete event has occurred in the second application;

determining, with the capture processor, an importance of the complete event; and

selectively indexing, with the capture processor, the complete event responsive to the importance of the complete event.

11. The method of claim 10, wherein the analyzing determines that a complete event has occurred responsive to the display indicating that a complete word has been entered into the application.

12. The method of claim 10, further comprising updating, with the capture processor, a capture state after each display call is processed.

13. The method of claim 10, further comprising updating, with the capture processor, a current user state based at least in part on the event.

14. The method of claim 10, wherein the display is determined at least in part by using an array of a current state of the display and updating the array with the display call, and wherein the analyzing comprises analyzing the array to determine whether a complete event has occurred.

15. The method of claim 10, wherein the display is determined at least in part by constructing display items based at least in part on display positions of the display calls.

16. The method of claim 10, wherein processing the plurality of display calls to determine a display comprises analyzing one or more of the x,y coordinates, lengths, and relative positions of a plurality of items written to the display using display calls.

17. A computer-readable storage medium for causing a capture processor to determine and selectively index an event associated with an application, the computer-readable storage medium containing executable program code comprising:

program code configured to receive a plurality of keystrokes associated with a first application with focus monitored by the capture processor, the first application with focus comprising an application being used by a user of the computer to enter text;
