A fundamental problem in text generation is word ordering. Word ordering is a computationally difficult problem, which can be constrained to some extent for particular applications, for example by using synchronous grammars for statistical machine translation. There have been some recent attempts at the unconstrained problem of generating a sentence from a multi-set of input words, and also some efforts to linearize unordered trees. We show that word ordering can be done using a syntax-based approach and learning-guided-search. This method tackles the factorial search space and allows state-of-the-art accuracies to be achieved given flexible input conditions.
