Abstract

A computer-implemented method, system and computer program product is provided for optimizing a document change or provenance scoring system by weighting sections of a document, scoring the changes for each section, and then combining the change scores for each section to generate an overall change score. An associated report may also be generated that catalogs all of the various scoring elements. The weighted score is stored in a document management system and provides a human document reviewer a level of detail to evaluate document changes. Accordingly, the weighted score reveals whether a document'"'"'s changes require a brief or detailed review before the document'"'"'s changes are approved for a next document version.

Claims

1. A computer-implemented method of indicating a degree of changes within a document comprising:

partitioning the document into a plurality of sections and assigning each section a corresponding weight value;

determining a quantity of changes within each section and applying the corresponding weight values to the quantity of changes to produce a section value for each section; and

determining a change value for the document indicating the degree of changes based on the section values.

2. The computer-implemented method of claim 1, further comprising:

identifying the document based on a comparison of the change value with a threshold.

3. The computer-implemented method of claim 1, further comprising:

determining the change value for a plurality of versions of the document; and

comparing the change values for the plurality of versions to identify a particular version.

4. The computer-implemented method of claim 1, wherein partitioning includes partitioning the document based on one or more of defined section labels and content of the document.

5. The computer-implemented method of claim 1, wherein assigning includes one or more of manually generating the corresponding weight for at least one section and automatically generating the corresponding weight for at least one section based on document content.

6. The computer-implemented method of claim 1, wherein determining a change value includes calculating the change value as one of:

a summation of the quantity of changes within each section multiplied by the corresponding weight values; and

a summation of the quantity of changes within each section multiplied by the corresponding weight values and divided by a quantity of the plurality of sections.

7. The computer-implemented method of claim 1, wherein each section is associated with a provenance value, and the method further comprising:

combining the section values of the document with provenance values of a previous version of the document to produce a new provenance value for each section; and

determining a current provenance value for the document based on the new provenance values for each section.

8. A system for indicating a degree of changes within a document comprising:

a computer system including at least one processor configured to;

partition the document into a plurality of sections and assign each section a corresponding weight value;

determine a quantity of changes within each section and apply the corresponding weight values to the quantity of changes to produce a section value for each section; and

determine a change value for the document indicating the degree of changes based on the section values.

9. The system of claim 8, wherein the at least one processor is further configured to:

identify the document based on a comparison of the change value with a threshold.

10. The system of claim 8, wherein the at least one processor is further configured to:

determine the change value for a plurality of versions of the document; and

compare the change values for the plurality of versions to identify a particular version

11. The system of claim 8, wherein the document is partitioned based on one or more of defined section labels and content of the document.

12. The system of claim 8, wherein assigning includes one or more of manually generating the corresponding weight for at least one section and automatically generating the corresponding weight for at least one section based on document content.

13. The system of claim 8, wherein determining a change value includes calculating the change value as one of:

a summation of the quantity of changes within each section multiplied by the corresponding weight values; and

a summation of the quantity of changes within each section multiplied by the corresponding weight values and divided by a quantity of the plurality of sections.

14. The system of claim 13, wherein each section is associated with a provenance value, and the at least one processor is further configured to:

combine the section values of the document with provenance values of a previous version of the document to produce a new provenance value for each section; and

determine a current provenance value for the document based on the new provenance values for each section.

15. A computer program product for indicating a degree of changes within a document comprising:

a computer readable storage medium having computer readable program code embodied therewith, the computer readable program code comprising computer readable program code configured to;

partition the document into a plurality of sections and assign each section a corresponding weight value;

determine a quantity of changes within each section and apply the corresponding weight values to the quantity of changes to produce a section value for each section; and

determine a change value for the document indicating the degree of changes based on the section values.

16. The computer program product of claim 15, wherein the computer readable program code further comprises computer readable program code configured to:

identify the document based on a comparison of the change value with a threshold.

17. The computer program product of claim 15, wherein the computer readable program code further comprises computer readable program code configured to:

determine the change value for a plurality of versions of the document; and

compare the change values for the plurality of versions to identify a particular version

18. The computer program product of claim 15, wherein the document is partitioned based on one or more of defined section labels and content of the document.

19. The computer program product of claim 15, wherein assigning includes one or more of manually generating the corresponding weight for at least one section and automatically generating the corresponding weight for at least one section based on document content.

20. The computer program product of claim 15, wherein determining a change value includes calculating the change value as one of:

a summation of the quantity of changes within each section multiplied by the corresponding weight values; and

a summation of the quantity of changes within each section multiplied by the corresponding weight values and divided by a quantity of the plurality of sections.

21. The computer program product of claim 20, wherein each section is associated with a provenance value, and the computer readable program code further comprises computer readable program code configured to:

combine the section values of the document with provenance values of a previous version of the document to produce a new provenance value for each section; and

determine a current provenance value for the document based on the new provenance values for each section.
