... solutions. Picky combines the standard chart parsing data structures with existing bottom-up and top-down parsing operations, and includes a probabilistic version of top-down filtering and over-the-top ... from the rest of the corpus during training. The training corpus consisted of 982 sentences which were parsed using the same grammar that Picky used. The training and t...
