Sparse language vectors from linguistic typology databases and learned embeddings from tasks like multilingual machine translation have been investigated in isolation, without analysing how they could benefit from each other's language characterisation. We propose to fuse both views using singular vector canonical correlation analysis and study what kind of information is induced from each source. By inferring typological features and language phylogenies, we observe that our representations embed typology and strengthen correlations with language relationships. We then take advantage of our multi-view language vector space for multilingual machine translation, where we achieve competitive overall translation accuracy in tasks that require information about language similarities, such as language clustering and ranking candidates for multilingual transfer. With our method, we can easily project and assess new languages without expensive retraining of massive multilingual or ranking models, which are major disadvantages of related approaches.

将来自语言数据库和多语言机器翻译等任务的稀疏语言向量相结合，使用奇异向量典型相关分析方法进行研究，发现这两种方法的关联性可嵌入语言类型学和语言谱系学，实现了对多语种机器翻译的优化，而且无需大规模的多语种编排，便于新语种的测量。
