The invention provides a method and a device for processing bilingual alignment corpora and relates to the technical field of machine translation, aiming at solving the problem that the efficiency of the bilingual alignment corpora processing method in the prior art is low. The method comprises the steps of acquiring a publishing date of an article in a first language; extracting the features of the article in the first language; screening out articles in a second language published on dates which are different from the publishing date of the article in the first language within a preset time threshold; extracting the features of the articles in the second language; computing a normalization editing distance between the article in the first language and each article in the second language according to the features of the article in the first language and the features of the articles in the second language; when the normalization editing distance between the article in the first language and the article in the second language is smaller than a preset distance threshold, using the article in the first language and the article in the second language as a pair of alignment corpora, adding the pair of alignment corpora into bilingual alignment corpora. The method and the device for processing bilingual alignment corpora are applicable to automatic processing of the bilingual alignment corpora.
