Table2: BETA evaluation for the Ro-EN lexicon of nouns; both COGN and DIST filters used The analysis of the wrong translation pairs revealed that most of them were hapax pairs (pairs appearing only once) and they were selected because the DIST measure enabled them, so we considered that this filter is not discriminative enough for hapaxes.
for the non-hapax pairs the DIST condition was successful in more than 85% of the cases.
