We trained Arabic-English cross-language word embeddings from the concatenation of these bitexts using bivec (Luong et al., 2015), a bilingual extension of word2vec, which has achieved excellent results on semantic tasks close to ours (Upadhyay et al., 2016).
we trained 200dimensional vectors using the parameters described in (Upadhyay et al., 2016), with a context window of size 5 and iterating for 5 epochs.
