Syntax Directed Translation with LR Parsing
Abstrac t . A simple extension of the usual LR parser construction is made in order to build a translator. The LR parsing algorithm is extended by a facility to do output operations within the action shift and reduce. A class of translation grammars, called R-translation grammars, is introduced as an extension of the class of postfix translation grammars. Transformations called shaking-down and...
متن کاملSyntax-Directed Attention for Neural Machine Translation
Attention mechanism, including global attention and local attention, plays a key role in neural machine translation (NMT). Global attention attends to all source words for word prediction. In comparison, local attention selectively looks at fixed-window source words. However, alignment weights for the current target word often decrease to the left and right by linear distance centering on the a...
متن کاملSyntax-Directed Phrase-based Statistical Machine Translation
The SDTS has been applied in the field of compiler and in transfer-based machine translation. After the parsing step, the syntactic structure of a sentence is identified. The parse tree will be analyzed, augmented, and transformed by later phases in the SMT system. Those phases are controlled by syntax. We use the stochastic SDTS to model such kind of translation process for phrase-based SMT. T...
متن کاملStatistical Syntax-Directed Translation with Extended Domain of Locality
In syntax-directed translation, the sourcelanguage input is first parsed into a parsetree, which is then recursively converted into a string in the target-language. We model this conversion by an extended treeto-string transducer that has multi-level trees on the source-side, which gives our system more expressive power and flexibility. We also define a direct probability model and use a linear...
