Abstract

A system for separating documents is disclosed. The system includes a multidimensional index creating module and a document separation criterion calculating module. The multidimensional index creating module calculates a multidimensional index for each documental material by calculating a plurality of document characteristic indexes from content information about individual documental materials contained in a primary document search result obtained in response to a search query received from a user device. The document separation criterion calculating module calculates a document separation criterion on the basis of both user preference information regarding at least one specific documental material selected from the documental materials contained in the primary document search result and the multidimensional index for the selected specific documental material. A secondary document search result is selected and provided according to the calculated document separation criterion among the documental materials contained in the primary document search result.

Claims

1. A system for separating documents, the system comprising:

a multidimensional index creating module configured to calculate a multidimensional index for each documental material by calculating a plurality of document characteristic indexes from content information about individual documental materials contained in a primary document search result obtained in response to a search query received from a user device; and

a document separation criterion calculating module configured to calculate a document separation criterion on the basis of both user preference information regarding at least one specific documental material selected from the documental materials contained in the primary document search result and the multidimensional index for the selected specific documental material,

wherein a secondary document search result is selected and provided according to the calculated document separation criterion among the documental materials contained in the primary document search result.

2. The system of claim 1, further comprising:

an evaluation module configured to verify the document separation criterion calculated by the document separation criterion calculating module, based on the probability that the selected specific documental material having the user preference is contained in the secondary document search result.

3. The system of claim 1, wherein the document separation criterion calculating module is further configured to calculate the document separation criterion through a regression analysis algorithm or a conditional analysis algorithm.

4. A search server comprising the document separation system recited in claim 1.

11. A search server comprising the document separation system recited in claim 2.

12. A search server comprising the document separation system recited in claim 3.

5. A method for separating documents, the method comprising:

creating a multidimensional index for each documental material by calculating a plurality of document characteristic indexes from content information about individual documental materials contained in a primary document search result obtained in response to a search query received from a user device;

calculating a document separation criterion on the basis of both user preference information regarding at least one specific documental material selected from the documental materials contained in the primary document search result and the multidimensional index for the selected specific documental material; and

providing a secondary document search result selected according to the calculated document separation criterion among the documental materials contained in the primary document search result.

6. The method of claim 5, further comprising:

after calculating the document separation criterion, verifying the document separation criterion calculated by the document separation criterion calculating module, based on the probability that the selected specific documental material having the user preference is contained in the secondary document search result.

7. The method of claim 5, wherein said calculating the document separation criterion includes calculating the document separation criterion through a regression analysis algorithm or a conditional analysis algorithm.

8. A computer-readable recording medium having thereon a program for executing the document separation method recited in claim 5.

9. A computer-readable recording medium having thereon a program for executing the document separation method recited in claim 6.

10. A computer-readable recording medium having thereon a program for executing the document separation method recited in claim 7.
