In order to assess the sensitivity of unsupervised <cite>BDI</cite> to the comparability and domain similarity of the monolingual corpora, we replicate the experiments in <cite>Conneau et al. (2018)</cite> using combinations of word embeddings extracted from three different domains: 1) parliamentary proceedings from EuroParl.v7 (Koehn, 2005) , 2) Wikipedia (Al- Rfou et al., 2013) , and 3) the EMEA corpus in the medical domain (Tiedemann, 2009) .
