 There are 4 subdirectories in MAC-Dev:
 
-The [zh](./data/mac/dev/zh) and [en](./data/mac/dev/en) directories contain the sentence-split and tokenized source texts, target texts and the machine translations of source texts. Hunalign requires tokenized source and target sentences for dictionary search of similar words. Bleualign uses MT translations of source texts to compute the Bleu similarity score between source and target sentences.

 We use [Moses sentence splitter](https://github.com/moses-smt/mosesdecoder/blob/master/scripts/ems/support/split-sentences.perl) and [Stanford CoreNLP](https://stanfordnlp.github.io/CoreNLP/usage.html) to split and tokenize English sentences, while [pyltp](https://github.com/HIT-SCIR/pyltp) and [jieba](https://github.com/fxsjy/jieba) are used to split and tokenize Chinese sentences. The MT of source texts are generated by [Google Translate](https://translate.google.cn/).
