摘要:

我们训练了一个多语种的依存句法分析模型,并使用它来分析几种语言的句子。解析模型使用(i)多语言词簇和嵌入;(ii)标记级语言信息;以及(iii)语言特定特征(细粒度POS标签)。这种输入表示使解析器不仅能够在多种语言中有效地解析,而且还能够基于语言共性和类型相似性来概括跨语言,从而使其更有效地从有限的注释中学习。我们的解析器的性能在一系列数据场景中优于强基线,包括当目标语言有一个大的树库,一个小的树库,或没有树库的训练。

英文摘要:

We train one multilingual model for dependency parsing and use it to parse sentences in several languages. The parsing model uses (i) multilingual word clusters and embeddings; (ii) token-level language information; and (iii) language-specific features (fine-grained POS tags). This input representation enables the parser not only to parse effectively in multiple languages, but also to generalize across languages based on linguistic universals and typological similarities, making it more effective to learn from limited annotations. Our parser's performance compares favorably to strong baselines in a range of data scenarios, including when the target language has a large treebank, a small treebank, or no treebank for training.
