Task: Question Answering
Input (English):  Plackett-Luce Model for SMT Reranking
After being de-duplicated, the N-best list has an average size of around 300, and with 7491 features. This experiment displays, in large-scale features, the Plackett-Luce model correlates with BLEU score very well, and alleviates overfitting in some degree. 
 Question: What experiments with large-scale features are performed?
Output (English): Plackett-Luce Model for SMT Reranking
