摘要:

并行语料库是提取多语言命名实体(MNE)资源的理想选择,即,翻译成多种语言的姓名数据集。先前从并行语料库中提取MNE数据集的工作需要资源,例如大型单语语料库或单词对齐器,这些资源对于资源不足的语言来说不可用或表现不佳。我们提出了CLC-BN,一种新的方法,用于创建MNE资源,并将其应用于并行圣经语料库,语料库的1000多种语言。CLC-BN从并行语料库统计中学习神经音译模型,而不需要任何其他双语资源,单词对齐器或种子数据。实验结果表明,CLC-BN明显优于以前的工作。我们发布了1340种语言的MNE资源,并在两个下游任务中证明了其有效性:知识图谱增强和双语词典归纳。

英文摘要:

Parallel corpora are ideal for extracting a multilingual named entity (MNE) resource, i.e., a dataset of names translated into multiple languages. Prior work on extracting MNE datasets from parallel corpora required resources such as large monolingual corpora or word aligners that are unavailable or perform poorly for underresourced languages. We present CLC-BN, a new method for creating an MNE resource, and apply it to the Parallel Bible Corpus, a corpus of more than 1000 languages. CLC-BN learns a neural transliteration model from parallel-corpus statistics, without requiring any other bilingual resources, word aligners, or seed data. Experimental results show that CLC-BN clearly outperforms prior work. We release an MNE resource for 1340 languages and demonstrate its effectiveness in two downstream tasks: knowledge graph augmentation and bilingual lexicon induction.
