<P>PROBLEM TO BE SOLVED: To provide a method for objectively showing the nature of a target data set for a certain reference frame. <P>SOLUTION: The method for determining a quantization scale of a corpus T<SB>3</SB>(20) includes steps for: selecting two reference corpora T<SB>1</SB>(22), T<SB>2</SB>(24), calculating formulae (1), (2) using cross entropy H, and determining a quantization scale of a corpus T<SB>3</SB>(I(T<SB>3</SB>))relative to the corpora T<SB>1</SB>, T<SB>2</SB>as a function represented by formula (3). <P>COPYRIGHT: (C)2006,JPO&NCIPI |
