Báo cáo khoa học: "Revisiting Pivot Language Approach for Machine Translation" doc

... This approach introduces a third language, named the pivot language, for which there exist large source -pivot and pivot- target bilingual cor- pora. A pivot task was also designed for spoken language ... method first translates from the source language to the pivot language using a source -pivot model, and then from the pivot lan- guage to the target language using...
