In our proposed method, the bilingual sentences are extracted using the translation matrix and the similarity between two language sentences based on the word embeddings. In that case, the Earth Mover's Distance is used to calculate the similarity. Moreover, the weight based on the difference of lengths between two language sentences is applied to the similarity in EMD. The evaluational experiments using the news article's comparable corpus indicate that the average of F-measure of our proposed method was 0.49, those of our proposed method without the weight based on the sentence length and the method based only on EMD were respectively 0.42, and that of the method using sentence length which is the baseline was 0.13.
