Abstract

Systems and/or methods (“tools”) are described that enable a recognition system to recognize user-entered data conforming to a data rule. The tools may do so by providing data regions for a document. With these data regions, the recognition system may better determine what information on the document is user-entered and what is not. Each of these data regions has a data rule governing data for that region. With the data rule, the recognition system may better recognize data from each region. The tools may ascertain these data regions and rules from an electronic form having controls laid out similarly to data-entry areas of the document.

Claims

1. One or more computer-readable media having computer-readable instructions therein that, when executed by a computer, cause the computer to perform acts comprising:

providing a two-dimensional region to a recognition system, the recognition system capable of extracting information from a document at the two-dimensional region; and

providing a data rule to the recognition system, the data rule corresponding to the two-dimensional region and enabling the recognition system to recognize, from information extracted from the document at the two-dimensional region, user-entered data on the document that conforms to the data rule.

2. The media of claim 1, wherein the recognition system comprises an optical character recognition software application.

3. The media of claim 1, wherein the two-dimensional region comprises position information mappable to a printed version of the document.

4. The media of claim 1, wherein:

the act of providing the two-dimension region provides multiple two-dimension regions;

the recognition system is capable of correlating a portion of a body of information extracted from the document with one of the multiple two-dimensional regions resulting in a correlated two-dimensional region and a correlated portion of the body of information; and

the act of providing the data rule provides the data rule corresponding to the correlated two-dimensional region thereby enabling the recognition system to recognize, from the correlated portion of the body of information, user-entered data on the document that conforms to the data rule corresponding to the correlated two-dimensional region.

5. The media of claim 1, further comprising generating the two-dimensional region and the data rule using an electronic form having a layout of controls oriented in two-dimensions similarly to a layout of user-entry areas of the document.

6. The media of claim 1, wherein the data rule requires non-numerical text.

7. The media of claim 1, wherein the recognition system is capable of extracting information from documents having an arbitrary layout of user-entry areas.

8. The media of claim 1, further comprising receiving user-entered data conforming to the data rule and storing the user-entered data in an instance of an electronic form.

9. A method comprising:

ascertaining a two-dimensional region of an electronic form permitting entry of data;

ascertaining one or more data rules corresponding to the two-dimensional region; and

providing the two-dimensional region and the one or more data rules effective to enable a recognition system to recognize user-entered data on a document at the two-dimensional region and conforming to the one or more data rules.

10. The method of claim 9, wherein the act of ascertaining the two-dimensional region ascertains two-dimensional coordinates bounding a control of the electronic form.

11. The method of claim 9, wherein the act of ascertaining the two-dimensional region parses a HyperText Machine Language (HTML) rendering of the electronic form.

12. The method of claim 9, wherein the act of ascertaining data rules analyzes a portion of a schema for the electronic form, the portion governing a control associated with the two-dimensional region.

13. The method of claim 9, wherein the data rules limit a type or length of text permitted in the two-dimensional region.

14. The method of claim 9, wherein the electronic form is the source of the document.

15. The method of claim 9, wherein the two-dimensional region is designed for handwritten or type-written entry of data.

16. The method of claim 9, further comprising building the electronic form based on the document, the electronic form built to have:

controls with a two-dimensional layout similar to that of user-entry areas of the document; and

data rules associated with the controls and requiring user-entered data of a type that the document implicitly or explicitly requires.

17. A method comprising:

extracting information from a two-dimensional document to provide extracted information;

differentiating the extracted information based on a two-dimensional region of the document to provided differentiated extracted information from the two-dimensional region and other extracted information not from the two-dimensional region; and

recognizing, from the differentiated extracted information, user-entered data conforming to a data rule, the data rule corresponding to the two-dimensional region.

18. The method of claim 17, further comprising receiving the two-dimensional region and the data rule.

19. The method of claim 17, wherein the two-dimensional region and the data rule are ascertained from a control of an electronic form, the electronic form having a two-dimensional layout of controls mappable to user-entry areas of the document.

20. The method of claim 19, further comprising providing the user-entered data effective to enable the user-entered data to be stored in an instance of the electronic form.
