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.
