A method and device for translating Chinese-English institution names with the aid of network knowledge

The invention relates to a method and device for translating Chinese-English organization names. The Chinese organization names to be translated are divided into four language blocks using a word-based conditional random field model, and word segmentation is performed on the four language blocks. Select words with a certain amount of information and translation confidence for statistical translation, get the translation results of several words in the organization name, and form a bilingual query with the Chinese organization name to be translated. Retrieve the query with the help of a search engine, and obtain several fragments of bilingual webpages in both Chinese and English. Extract the English in the webpage fragments, and use the Chinese-English asymmetric alignment technology to screen the fragments in the English sentences that have the highest probability of being aligned with the Chinese organization name. By counting information such as the frequency of occurrence of each segment, an optimal segment is determined as the translation of the Chinese institution name. This method overcomes the structure, sequence and word selection errors that the statistical translation model tends to produce in the translation process of institution names, and the accuracy rate of institution name translation is increased by 35.26%.
