<P>PROBLEM TO BE SOLVED: To provide an encoding technology which achieves decrease in data size and improvement in analysis processing speed, even to data including elements having complicated attribute values. <P>SOLUTION: An information processing device is provided with; a file input means which inputs files including elements having a data stream of prescribed format as the attribute values; a hierarchical information setting means which sets hierarchical information, which indicates hierarchical positions, for each of one or more delimiters included in the data stream; a structure information generating means which generates structure information which defines the interrelations of the hierarchical information; a designating means which designates the area of the data stream of prescribed format from the input files; and an encoding means which detects the delimiters from the designated area and encodes the data stream of the area, which are designated on the basis of the detected delimiters and the structure information, on the basis of a preliminarily set structurization description language. <P>COPYRIGHT: (C)2009,JPO&INPIT |
