Example GIZA Lex file

[shamilcm]

The third column of the example GIZA provided (lang_resources/giza/lex.e2s) has probabilities of English word given the aligned Spanish word ( i.e. p(en|es) ). Am I correct? Is this the right Giza file to be used with Quest++ for quality estimation of an en-es MT system?

Hi Shamil, that is correct.

Regards,

Thanks. Just an additional clarification:

In the list of features given here (as well as previous shared tasks on QE): https://www.quest.dcs.shef.ac.uk/quest_files/features_blackbox_baseline_17

for features 7 and 8 which uses the GIZA++ probabilities, shouldn't the probability thresholds be p(s|t) and not p(t|s)? Since the target language is Spanish and source language is English, GIZA++ Lex file only has probability (en|es) and not porbability (es|en).

If I'm not totally misremembering it (sorry, long time not using GIZA++), the probabilities in GIZA files are p(t|s) already :)
