Abstract: Disclosed is a system and a method for automatically classifying search results. The system includes a search engine server for obtaining and providing search results with regard to a search word entered by the user, grouping the obtained search results according to meanings of the search word, and providing the grouped search results; a related word database for storing related words classified into groups according to meanings of the search word; and a group determination system for receiving search results from the search engine server, comparing the contents of the search results with the related words stored in the related word database to determine which group of the related word database the search results belong to, and storing search results at a predetermined place when the search results are not grouped.

Abstract: The present invention is related to a ferroelectric storage medium for ultrahigh density data storage device and a method for fabricating the same. A supercell having high anisotropy is formed by controlling crystal structure and symmetry of unit structure (supercell) of artificial lattice by using an ordered alignment of predetermined ions having orientation of (perpendicular) deposition direction. Unit atomic layers of oxides having different polarization characteristic are deposited so that the supercell itself shows electric polarization having only two, upward and downward directions as one block of supercell having single-directional polarization. Oxide artificial lattices can be formed so as to have solely 180 degree domain structure, thus a single electric domain having improved anisotropic characteristic can be formed, thereby allowing capability of ultrahigh density data storage and long term data retention.
