Weighted Set-Theoretic Alignment of Comparable Sentences
Andoni Azpeitia, Thierry Etchegoyhen, Eva Martínez García · 2017
This article presents the STACC w system for the BUCC 2017 shared task on parallel sentence extraction from comparable corpora.The original STACC approach, based on set-theoretic operations over bags of words, had been previously shown to be efficient and portable across domains and alignment scenarios.We describe an extension of this approach with a new weighting scheme and show that it provides significant improvements on the datasets provided for the shared task.
