论文摘要
最近，无监督的双语词典诱导（BLI）没有任何平行的语料库吸引了很多研究兴趣。 BLI任务方法中的关键部分之一是匹配过程。以前的作品对匹配施加了太大的限制，并导致许多违反直觉的翻译配对。因此，我们提出了一个轻松的匹配程序，以在两种语言之间找到更精确的匹配。我们还发现，在双向上对齐源和目标语言嵌入空间将带来重大改进。我们遵循以前的迭代框架进行实验。标准基准的结果证明了我们提出的方法的有效性，该方法显着优于先前无监督的方法。
Recently unsupervised Bilingual Lexicon Induction (BLI) without any parallel corpus has attracted much research interest. One of the crucial parts in methods for the BLI task is the matching procedure. Previous works impose a too strong constraint on the matching and lead to many counterintuitive translation pairings. Thus, We propose a relaxed matching procedure to find a more precise matching between two languages. We also find that aligning source and target language embedding space bidirectionally will bring significant improvement. We follow the previous iterative framework to conduct experiments. Results on standard benchmark demonstrate the effectiveness of our proposed method, which substantially outperforms previous unsupervised methods.
