In this paper we compare and contrast two approaches to Machine Translation (MT): the CMU-UKA Syntax Augmented Machine Translation system (SAMT) and UPC-TALP N-gram-based Statistical Machine Translation (SMT). SAMT is a hierarchical syntax-driven translation system underlain by a phrase-based model and a target part parse tree. In N-gram-based SMT, the translation process is based on bilingual units related to word-to-word alignment and statistical modeling of the bilingual context following a maximumentropy framework. . | N-gram-based Statistical Machine Translation versus Syntax Augmented Machine Translation comparison and system combination Maxim Khalilov and José . Fonollosa Universitat Politècnica de Catalunya Campus Nord UPC 08034 Barcelona Spain khalilov adrian @ Abstract In this paper we compare and contrast two approaches to Machine Translation MT the CMU-UKA Syntax Augmented Machine Translation system SAMT and UPC-TALP N-gram-based Statistical Machine Translation SMT . SAMT is a hierarchical syntax-driven translation system underlain by a phrase-based model and a target part parse tree. In N-gram-based SMT the translation process is based on bilingual units related to word-to-word alignment and statistical modeling of the bilingual context following a maximumentropy framework. We provide a step-by-step comparison of the systems and report results in terms of automatic evaluation metrics and required computational resources for a smaller Arabic-to-English translation task tokens in the training corpus . Human error analysis clarifies advantages and disadvantages of the systems under consideration. Finally we combine the output of both systems to yield significant improvements in translation quality. 1 Introduction There is an ongoing controversy regarding whether or not information about the syntax of language can benefit MT or contribute to a hybrid system. Classical IBM word-based models were recently augmented with a phrase translation capability as shown in Koehn et al. 2003 or in more recent implementation the MOSES MT sys-tem1 Koehn et al. 2007 . In parallel to the phrasebased approach the N-gram-based approach appeared Marino et al. 2006 . It stemms from 1 moses the Finite-State Transducers paradigm and is extended to the log-linear modeling framework as shown in Marino et al. 2006 . A system following this approach deals with bilingual units called tuples which are composed of one or more words from the source language and zero or .
