Bleu score in Python is a metric that measures the goodness of Machine Translation models. Though originally it was designed for only translation models, now it is used for othernatural language processing applicationsas well. The BLEU score compares a sentence against one or more reference sentence...
Cumulative scores refer to the calculation of individual n-gram scores at all orders from 1 to n and weighting them by calculating the weighted geometric mean. By default, thesentence_bleu()andcorpus_bleu()scores calculate the cumulative 4-gram BLEU score, also calledBLEU-4. The weights for ...

Generally speaking, the scale of GEO-BLEU scores for the tasks can be quite small, possibly on the order of 10^-3 or 10^-4, due to the calculation involving exponential terms taking negative input values. If that is the case for the majority of submissions, we organizers will be presenti...
