12. A system, comprising; a processor; memory coupled to said processor, where the memory stores instructions to be executed by the processor to perform steps comprising: tagging a source-language sentence with non-lexical tags; parsing the tagged source-language sentence using a source language lexicalized parser to generate a parse tree for the sentence, where the source language lexicalized parser has been trained using gold standard source-language data; tagging a target-language sentence with non-lexical tags, where the target-language sentence is a translation of the source-language sentence; parsing the tagged target-language sentence with a delexicalized parser to generate a set of k-best parse trees for the target-language sentence; selecting the best target-language parse tree of the k-best parse trees that most closely aligns with the lexicalized parse tree of the source-language sentence; and updating a parameter vector of a target language lexicalized parser based upon the selected best target-language parse tree.
13. The system of claim 12 , wherein the non-lexical tags are parts of speech tags.
