A Common Semantic Space for Monolingual and Cross-Lingual Meta-Embeddings
Table 6: Multilingual and Cross-lingual word similarity results using cross-lingual meta-embeddings.
['Embedding', 'EN-EN', 'ES-ES', 'EN-ES']
We include the results of some state-of-the-art monolingual embeddings, and the cross-lingual embeddings such as JOINTChyb (J), Numberbatch (N) and the ones from Doval et al. Compared to all these embeddings, our cross-lingual meta-embeddings obtain the best results for English, slightly better for Spanish and slightly lower than Numberbatch on the cross-lingual datasets. Surprisingly, our cross-lingual results are slightly lower than Numberbatch due to an increase in coverage (less OOV). Providing answers for the same word-pairs as Numberbatch, our meta-embedding MVM3enes obtains in the cross-lingual English-Spanish a result of 80.4 which indicates a small improvement of the cross-lingual meta-embedding.
