English to Persian Translation Using Synchronous Tree Adjoining Grammars

Abstract: Increasing the domain of locality by using tree-adjoining-grammars (TAG) caused some applications, such as machine translation, to employ it for disambiguation process [2]. Successful experiments of applying TAG grammar to French-English and Korean-English machine translation encouraged us to use it for another language pairs with very divergent properties, Persian and English [2, 10]. Using Synchronous TAG (S-TAG) for this pair of languages can benefit from syntactic and semantic features for transferring the source language to a target language. S-TAG, is a pair of TAGs for source-target languages with some correspondence between the nodes of elementary trees of TAGs. Here, we report our experiments in the translation from English into Persian. We discuss problems that are specific to Persian and propose appropriate solutions
