METADATA GENERATION APPARATUS, METADATA RESTRICTION DEFINITION PROCESSOR, AND ITS CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To use a metadata restriction definition of high reliability.;SOLUTION: The metadata restriction definition processor is provided with: a point addition part 4 for adding points to each cell in a table; a metadata generation part 5 which selects a row and a column having highest points, selects one of them, and generates metadata comprising (a) a subject equal to content of a cell which is included one and not included in the other; (b) a predicate equal to content of the cell which is included in the latter and not in the former; and (c) an object equal to content of the cell where either the row or column including the cell of the subject and being vertical to one intersects with either the row or column including the cell of the predicate and being vertical to the other; and a metadata restriction definition generation part 6 for generating the metadata restriction definition which comprises (A) subject notion granted to the table, (B) a predicate included in the generated metadata, and (C) object notion of an object included in the metadata. The metadata restriction definition generation part 6 stores a plurality of metadata restriction definitions including an identical subject notion and an identical predicate in a metadata restriction definition storage part 2.;COPYRIGHT: (C)2007,JPO&INPIT
