PROBLEM TO BE SOLVED: To provide a translation pair extraction device for automatically extracting translation pairs from a non-parallel corpus with high accuracy even when a dictionary is small scale.SOLUTION: A translation pair extraction device 160 comprises: a relevance graph preparation part 200 which extracts words to be extraction objects of paginal translation expression from each of a document set 170 of a first language and a document set 172 of a second language, respectively, and calculates direct relevance between the words based on co-occurrence frequencies of the words to prepare a relevance graph between the words; a seed information propagation part 204 which calculates overall relevance including indirect relevance between each of the words and each of a plurality of translation pairs by using the direct relevance between the words calculated by the relevance graph creation part 200 to generate context vectors; a relevance similarity calculation part 180 and a word pair extraction part 182 which select combination of which the similarity of corresponding context vectors becomes a reference value or more as paginal translation expression among combinations of the words of the first language and the words of the second language.
