Symmetric probabilistic alignment
Ralf D. Brown, Jae Dong Kim, Peter Jansen, Jaime Carbonell · 2005
We recently decided to develop a new alignment algorithm for the purpose of improving our Example-Based Machine Translation (EBMT) system's performance, since subsentential alignment is critical in locating the correct translation for a matched fragment of the input. Unlike most algorithms in the literature, this new Symmetric Probabilistic Alignment (SPA) algorithm treats the source and target languages in a symmetric fashion.
