We present an approach to text simplifi- cation based on synchronous dependency grammars. The higher level of abstraction afforded by dependency representations allows for a linguistically sound treatment of complex constructs requiring reorder- ing and morphological change, such as conversion of passive voice to active. We present a synchronous grammar formalism in which it is easy to write rules by hand and also acquire them automatically from dependency parses of aligned English and Simple English sentences. The grammar formalism is optimised for monolingual translation in that it reuses ordering infor- mation from the source sentence where ap- propriate. We demonstrate the superiority of our approach over a leading contempo- rary system based on quasi-synchronous tree substitution gram...
