An EM algorithm for SCFG in formal syntax-based translation

In this paper, we investigate the use of bilingual parsing on parallel corpora to better estimate the rule parameters in a formal syntax-based machine translation system, which are normally estimated from the inaccurate heuristics. We use an expectation-maximization (EM) algorithm to re-estimate the...
