Abstract

The disclosed embodiments relate to a computer system that facilitates identifying additional tax information. During operation, the computer system receives tax information. Next, the computer system determines relevance of the additional tax information to the tax information using a metric indicative of a statistical relationship between the tax information and the additional tax information in a tax-information data structure. This metric is based on co-existence of the tax information and the additional tax information at different hierarchical levels in income-tax documents. Moreover, the tax-information data structure includes tax information and associated context information from income-tax documents. Next, the computer system identifies the additional tax information based on the relevance and a threshold, and the computer system provides the additional tax information.

Claims

1. A computer-implemented method for identifying and providing additional tax information, comprising:

receiving tax information;

determining, by computer, relevance of the additional tax information to the tax information, by;

identifying a tax-information data structure in one-or-more documents,

identifying the tax information and the additional tax information within the tax-information data structure,

determining the hierarchical levels of the tax information and the additional tax information within the tax-information data structure, wherein the hierarchical levels are based upon the proximity of the tax information in relation to the additional tax information within the tax-information data structure,

calculating a statistical metric that describes the statistical relationship between the tax information and the additional tax information in a tax-information data structure, including the hierarchical levels, based on coexistence of the tax information and the additional tax information at different hierarchical levels in the tax-information data structure, wherein the tax information and the additional tax information are not directly linked, and

wherein determining the relevance involves determining a weighted sum of contributions associated with the co-existence of the tax information and the additional tax information at the different hierarchical levels in income-tax documents;

identifying the additional tax information based on the relevance and a threshold; and

providing the additional tax information.

2. The method of claim 1, wherein the hierarchical levels in a given income-tax document include sentence-level co-existence, paragraph-level co-existence, section-level co-existence, and co-existence in a worksheet.

3. The method of claim 1, wherein the additional tax information includes a tax concept that incorporates the tax information.

4. The method of claim 3, wherein the additional tax information includes an income-tax topic.

5. The method of claim 1, wherein the additional tax information provides a location with additional information associated with the tax information.

6. The method of claim 1, wherein the additional tax information provides help content associated with the tax information.

7. The method of claim 1, wherein the income-tax documents include income-tax forms and income-tax guides.

8. The method of claim 1, wherein the context information includes locations associated with the tax information in the income-tax documents.

9. The method of claim 8, wherein the locations include at least one of a page in an income-tax document, a worksheet associated with the income-tax document, and lines in the worksheet.

10. A non-transitory computer-program product for use in conjunction with a computer system, the computer-program product comprising a computer-readable storage medium and a computer-program mechanism embedded therein, to facilitate identifying and providing, the computer-program mechanism including:

instructions for receiving tax information;

instructions for determining relevance of the additional tax information to the tax information, by;

identifying a tax-information data structure in one-or-more documents,

identifying the tax information and the additional tax information within the tax-information data structure,

determining the hierarchical levels of the tax information and the additional tax information within the tax-information data structure, wherein the hierarchical levels are based upon the proximity of the tax information in relation to the additional tax information within the tax-information data structure,

calculating a statistical metric that describes the statistical relationship between the tax information and the additional tax information in a tax-information data structure, including the hierarchical levels, based on coexistence of the tax information and the additional tax information at different hierarchical levels in the tax-information data structure, wherein the tax information and the additional tax information are not directly linked, and

wherein determining the relevance involves determining a weighted sum of contributions associated with the co-existence of the tax information and the additional tax information at the different hierarchical levels in income-tax documents;

instructions for identifying the additional tax information based on the relevance and a threshold; and

instructions for providing the additional tax information.

11. The computer-program product of claim 10, wherein the hierarchical levels in a given income-tax document include sentence-level co-existence, paragraph-level co-existence, section-level co-existence, and co-existence in a worksheet.

12. The computer-program product of claim 10, wherein the additional tax information includes a tax concept that incorporates the tax information.

13. The computer-program product of claim 12, wherein the additional tax information includes an income-tax topic.

14. The computer-program product of claim 10, wherein the additional tax information provides a location with additional information associated with the tax information.

15. The computer-program product of claim 10, wherein the additional tax information provides help content associated with the tax information.

16. The computer-program product of claim 10, wherein the income-tax documents include income-tax forms and income-tax guides.

17. The computer-program product of claim 10, wherein the context information includes locations associated with the tax information in the income-tax documents.

18. The computer-program product of claim 17, wherein the locations include at least one of a page in an income-tax document, a worksheet associated with the income-tax document, and lines in the worksheet.

19. A computer system, comprising:

a processor;

memory; and

a program module, wherein the program module is stored in the memory and configurable to be executed by the processor to facilitate identifying and providing, the program module including;

instructions for receiving tax information;

instructions for determining relevance of the additional tax information to the tax information, by;

identifying a tax-information data structure in one-or-more documents,

identifying the tax information and the additional tax information within the tax-information data structure,

determining the hierarchical levels of the tax information and the additional tax information within the tax-information data structure, wherein the hierarchical levels are based upon the proximity of the tax information in relation to the additional tax information within the tax-information data structure,

calculating a statistical metric that describes the statistical relationship between the tax information and the additional tax information in a tax-information data structure, including the hierarchical levels, based on coexistence of the tax information and the additional tax information at different hierarchical levels in the tax-information data structure, wherein the tax information and the additional tax information are not directly linked, and

wherein determining the relevance involves determining a weighted sum of contributions associated with the co-existence of the tax information and the additional tax information at the different hierarchical levels in income-tax documents;

instructions for identifying the additional tax information based on the relevance and a threshold; and

instructions for providing the additional tax information.
