Abstract

The present invention provides a document processing device including: a specifying unit that specifies character strings which have a common property across documents, from among character strings included in plural documents which are represented by plural corresponding document data; and a rewriting unit that rewrites, among the character strings specified by the specifying unit, character strings expressed in formats different from a defined format to character strings expressed in the defined format.

Claims

1. A document processing device comprising:

a specifying unit that specifies character strings which have a common property across documents, from among character strings included in a plurality of documents which are represented by a plurality of corresponding document data; and

a rewriting unit that rewrites, among the character strings specified by the specifying unit, character strings expressed in formats different from a defined format to character strings expressed in the defined format.

2. The document processing device according to claim 1, further comprising:

a classifying unit that classifies formats of character strings specified by the specifying unit; and

a defining unit that defines a reference format based on a classification result provided by the classifying unit,

wherein the rewriting unit rewrites, among the character strings specified by the specifying unit, character strings expressed in formats different from a reference format defined by the defining unit to character strings expressed in the reference format.

3. The document processing device according to claim 2, wherein the defining unit defines as the reference format a format with a highest appearance frequency from among formats classified by the classifying unit.

4. The document processing device according to claim 2, further comprising:

a display that displays a list of a plurality of formats which are a classification result of the classifying unit; and

a selecting unit that selects a format from a list of a plurality of formats displayed by the display according to an operation of the operator,

wherein the rewriting unit rewrites, among the character strings specified by the specifying unit, character strings expressed in formats different from a format selected by the selecting unit to character strings expressed in the selected format.

5. The document processing device according to claim 1, further comprising:

a filename rewriting unit that rewrites a filename of document data whose character string has been rewritten by the rewriting unit to a filename including at least a portion of the rewritten character string.

6. The document processing device according to claim 1, further comprising:

a filename rewriting unit that rewrites a filename of document data whose character string has been rewritten by the rewriting unit to a filename including at least a portion of a name indicating a property of the rewritten character string.

7. The document processing device according to claim 5, further comprising:

a rewriting selection unit that allows an operator to select whether to rewrite a filename,

wherein the filename rewriting unit rewrites a filename of document data whose character string has been rewritten by the rewriting unit when the rewriting selection unit has received an instruction from an operator to rewrite the filename.

8. The document processing device according to claim 6, further comprising:

a rewriting selection unit that allows an operator to select whether to rewrite a filename,

wherein the filename rewriting unit rewrites a filename of document data whose character string has been rewritten by the rewriting unit when the rewriting selection unit has received an instruction from an operator to rewrite the filename.

9. The document processing device according to claim 1, wherein the document data is obtained by applying an OCR (Optical Character Recognition) process to an optically-read document.

10. A document processing method performed by a document processing device, comprising:

specifying character strings which have a common property across documents, from among character strings included in a plurality of documents which are represented by a plurality of corresponding document data; and

rewriting, among character strings specified in the specifying step, character strings expressed in formats different from a defined format to character strings expressed in the defined format.

11. The document processing method according to claim 10, further comprising:

classifying formats of character strings specified in the specifying step; and

defining a reference format based on a result of a classification in the classifying step,

wherein the character string rewriting step includes rewriting, among character strings specified in the specifying step, character strings expressed in formats different from a reference format defined in the defining step to character strings expressed in the reference format.

12. The document processing method according to claim 11, wherein the defining step includes defining as the reference format a format with a highest appearance frequency from among formats classified in the classifying step.

13. The document processing method according to claim 11, further comprising:

displaying a list of a plurality of formats which are a result of a classification in the classifying step; and

selecting a format from a list of a plurality of formats displayed in the displaying step according to an operation of the operator,

wherein the character string rewriting step includes rewriting, among character strings specified in the specifying step, character strings expressed in formats different from a format selected in the format selecting step to character strings expressed in the selected format.

14. The document processing method according to claim 10, further comprising:

rewriting a filename of document data whose character string has been rewritten in the character string rewriting step to a filename including at least a portion of the rewritten character string.

15. The document processing method according to claim 10, further comprising:

rewriting a filename of document data whose character string has been rewritten in the character string rewriting step to a filename including at least a portion of a name indicating a property of the rewritten character string.

16. The document processing method according to claim 14, further comprising:

allowing an operator to select whether to rewrite a filename,

wherein the filename rewriting step includes rewriting a filename of document data whose character string has been rewritten in the character string rewriting step when an instruction from an operator to rewrite the filename is received in the rewriting selection step.

17. The document processing method according to claim 15, further comprising:

allowing an operator to select whether to rewrite a filename,

wherein the filename rewriting step includes rewriting a filename of document data whose character string has been rewritten in the character string rewriting step when an instruction from an operator to rewrite the filename is received in the rewriting selection step.

18. The document processing method according to claim 10, wherein the document data is obtained by applying an OCR (Optical Character Recognition) process to an optically-read document.

19. A computer-readable storage medium recording a program for causing a computer to execute:

specifying character strings which have a common property across documents, from among character strings included in a plurality of documents which are represented by a plurality of corresponding document data; and

rewriting, among character strings specified by the specifying process, character strings expressed in formats different from a defined format to character strings expressed in the defined format.
