Some methods do not have publicly available code (Coulmance et al., 2015;Zou et al., 2013); for others, like BilBOWA , we identified problems in the available code, which caused it to consistently produced results that are inferior even to mono-lingually trained vectors.
11 the models that we included for comparison in our survey are representative of other cross-lingual models in terms of the form of crosslingual supervision required by them.
