MITRE Chinese-English Biology Abstract Parallel Text This is a dataset of parallel sentences of Mandarin and English from a collection of chemistry and biology-related scientific articles published in Mandarin and translated into English by translators with particular expertise in the technical area. Translators were instructed to err on the side of literal translation if required, but to maintain the technical writing style of the source and make the resulting English as natural as possible. The translators were given specific guidelines for translation, and those are included in this distribution. All translations were subject to a three-step quality control process. There are 2239 lines of parallel Mandarin and English, with a total of 156445 characters of Mandarin and 75515 words of English, presented in a separate plain text file for each language. The sentences were translated in sequential order and are presented here in a scrambled order, such that parallel sentences at identical line numbers are translations. For example, the 31st line of the English file is a translation of the 31st line of the Mandarin file. The original ordering of the lines will not be provided. ©2012-The MITRE Corporation.
