摘要:

跨语言词嵌入在同一向量空间中表示来自不同语言的词汇项,从而实现NLP工具的传输。然而,以前的尝试有昂贵的资源需求,难以纳入单语数据或无法处理一词多义。我们解决这些缺点,在我们的方法中,利用高覆盖率的字典在EM风格的训练算法在两种语言的单语语料库。我们的模型实现了最先进的性能双语词汇归纳任务超过模型使用大型双语语料库,单语词相似性和跨语言文档分类任务的竞争结果。

英文摘要:

Crosslingual word embeddings represent lexical items from different languages in the same vector space, enabling transfer of NLP tools. However, previous attempts had expensive resource requirements, difficulty incorporating monolingual data or were unable to handle polysemy. We address these drawbacks in our method which takes advantage of a high coverage dictionary in an EM style training algorithm over monolingual corpora in two languages. Our model achieves state-of-the-art performance on bilingual lexicon induction task exceeding models using large bilingual corpora, and competitive results on the monolingual word similarity and cross-lingual document classification task.
