Abstract

Provided are a document management system and method. The document management system including a database storing documents and a document classification unit for automatically classifying the documents stored in the database, wherein the document classification unit comprises a feature extraction module extracting features based on a keyword included in the documents and vectorizing the extracted features, a similarity judgment module judging similarity among the documents using vectors formed by the feature extraction module, and a classification system module classifying the documents stored in the database according to a preset classification system, the document classification unit performing document classification according to the classification system with respect to documents provided to the database.

Claims

1. A document management system, comprising:

a database storing documents; and

a document classification unit for automatically classifying the documents stored in the database,

wherein the document classification unit comprises a feature extraction module extracting features based on a keyword included in the documents and vectorizing the extracted features, a similarity judgment module judging similarity among the documents using vectors formed by the feature extraction module, and a classification system module classifying the documents stored in the database according to a preset classification system,

the document classification unit performing document classification according to the classification system with respect to documents provided to the database.

2. The document management system according to claim 1, wherein the document classification by the document classification unit is performed at each period set by a user.

3. The document management system according to claim 1, wherein the classification system is classified using classification code classified and formed by features according to technology fields.

4. The document management system according to claim 1, further comprising a newly received information service unit for informing a user of information about new documents.

5. The document management system according to claim 4, wherein the newly received information service unit provides the information about the new documents to the user in case that the new documents has similarity within a predetermined range according to a judgment result of the similarity judgment module.

6. The document management system according to claim 4, wherein the newly received information service unit sends an alarm mail to the user in case that the new documents are provided to the database.

7. The document management system according to claim 6, wherein a user setting receiving the alarm mail is modifiable through a predetermined input module provided to the user.

8. The document management system according to claim 1, wherein the similarity of the documents judged by the similarity judgment module is settable by the user through an input module of a client.

9. The document management system according to claim 1, wherein the documents are publication patent documents or registration patent documents, and

the system further comprising a document management unit extracting a representative value corresponding to a legal status of the documents and judging a change of the legal status of other document from the extracted representative value.

10. The document management system according to claim 9, further comprising a newly received information service unit for providing changed contents to a user when the legal status of the documents is changed according to a judgment result of the document management unit.

11. A document management method, comprising:

extracting features from documents stored in a database and judging similarity among the documents using the extracted features;

classifying the documents stored in the database according to a predetermined classification system based on the similarity among the documents; and

supervising whether or not new documents are provided to the database, and automatically performing the extracting of the features and the classifying of the documents with regard to the new documents in case that the new documents are provided.

12. The method according to claim 11, wherein the classifying of the documents is performed according to a classification code formed by classifying features for each technology field.

13. The method according to claim 11, wherein the supervising of whether or not the new documents are provided is performed at each period set by a user.

14. The method according to claim 11, further comprising providing information about the new documents to a user in case that the new document has similarity within a predetermined range.

15. The method according to claim 14, wherein a similarity condition is modifiable through a predetermined input module inputting a keyword by the user, in the judging of similarity with regard to the new documents is capable of changing.

16. The method according to claim 11, wherein the documents stored in the database are publication patent documents or registration patent documents, and

the method further comprising confirming a legal status of the documents from bibliographic information included in the documents and judging a change of the legal status of the documents using the confirmed legal status of the documents.

17. The method according to claim 16, further comprising providing information about the legal status of the documents to a user in case that the legal status of the documents are changed.
