<P>PROBLEM TO BE SOLVED: To provide a bilingual degree calculation device capable of calculating accurate bilingual degree using only pair data of a bilingual document. <P>SOLUTION: A bilingual degree calculation device 1 which calculates bilingual degree using pair data of a bilingual document comprises: a co-occurrence frequency in a language totalling part 15 totalling a co-occurrence frequency in a language; a co-occurrence frequency between languages totalling part 16 totalling a co-occurrence frequency between languages; a probability in a language calculation part 18 calculating a probability that all elements of a different word set W<SB POS="POST">1</SB>are included in a sentence, based on a co-occurrence frequency in a language; a probability between languages calculation part 19 calculating a probability that all elements of different word sets W<SB POS="POST">1</SB>and W<SB POS="POST">2</SB>are separately included in a sentence of each language based on a co-occurrence frequency between languages; and a bilingual degree calculation part 20 calculating a bilingual degree based on a calculation result of the probability between languages calculation part 19 and the probability in a language calculation part 18. <P>COPYRIGHT: (C)2012,JPO&INPIT |
