Umsuka English - isiZulu Parallel Corpus

We’ve developed an open-source, high quality isiZulu parallel corpus that comes from a<br> mixture of domains, taking into account both Southern African context and international<br> English context, by using professional translators. We sourced 5000 English sentences,<br> sampled from News Crawl datasets that were translated into isiZulu. Additionally, we<br> translated 5000 isiZulu sentences, sampled from both the NCHLT monolingual corpus and<br> the open-source documents of the UKZN isiZulu National monolingual corpus, into English.<br> From each set, we separated out 1000 patterns as the evaluation dataset. Since isiZulu is<br> highly morphologically complex, we believe that the English-to-isiZulu evaluation set should<br> be translated at least twice, by different translators which will allow us to calculate<br> human-level BLEU score for the dataset.

本团队开发了一款开源、高质量的祖鲁语（isiZulu）平行语料库，该语料库涵盖多领域文本，兼顾南非本土语境与国际英语语境，全部译制工作均由专业译员完成。
我们从News Crawl数据集中采样得到5000条英语句子，并将其翻译为祖鲁语。此外，我们从NCHLT单语语料库以及UKZN祖鲁语国家单语语料库的开源文档中采样得到5000条祖鲁语句子，并将其翻译为英语。
我们从每个子集中各划分出1000条语料对作为评估数据集。
鉴于祖鲁语具有极强的形态复杂性，我们认为英语到祖鲁语的评估集应由不同译员至少完成两次翻译，借此我们可计算该数据集的人类基准BLEU评分。
