Center node: "neural machine translation for low resource languages using bilingual lexicon induced from comparable corpora"
  Abstract: Resources for the non-English languages are scarce and this paper addresses this problem in the context of machine translation, by automatically extracting parallel sentence pairs from the multilingual articles available on the Internet. In this paper, we have used an end-to-end Siamese bidirectional recurrent neural network to generate parallel sentences from comparable multilingual articles in Wikipedia. Subsequently, we have showed that using the harvested dataset improved BLEU scores on both NMT and phrase-based SMT systems for the low-resource language pairs: English--Hindi and English--Tamil, when compared to training exclusively on the limited bilingual corpora collected for these language pairs.

Connected through hyperedge HE-1 (induced by source paper "word2word a collection of bilingual lexicons for 3 564 language pairs"):
  with members:
    - "a survey of cross lingual word embedding models"
    - "bilingual lexicon induction through unsupervised machine translation"
    - "pointer based fusion of bilingual lexicons into neural machine translation"
    - "how to properly evaluate cross lingual word embeddings on strong baselines comparative analyses and some misconceptions"
    - "a robust self learning method for fully unsupervised cross lingual mappings of word embeddings"
    - "word translation without parallel data"
    - "a strong baseline for learning cross lingual word embeddings from sentence alignments"
    - "distributed representations of words and phrases and their compositionality"
