Lidia Sam Chao, Derek F. Wong, Chi Hong Ao, Ana Leal · 2018
This paper describes the creation of a high quality parallel corpus for Portuguese and Chinese that extracted from parallel and comparable documents. The corpus is constructed using an on-line alignment platform, UM-pAligner. The UM-pAligner consists of two main alignment components, parallel sentence identification and classification model, for acquiring the parallel sentences from either the parallel or comparable texts in a semi-automatic manner. The extracted parallel sentences are manually verified. The resulting corpus is composed of the parallel sentences covering the texts of the newswire, legal, subtitle, technical and general on-line publications, around 6 million parallel sentences. About 1 million parallel sentences are compiled and made available for download at the NLP2CT website.
