我们研究了Sparky Restaurant语料库中对比连接词的平均频率，以及人类评委对实现的评级。我们实现了辨别性n元语法排序器来对这些评级进行建模，并分析所得到的n元语法权重以确定我们的排序器是否学习了该分布。令人惊讶的是，我们的排名者学会了避免对比连接词。我们研究了这种分布的可能解释，并建议改进句子计划/实现的生成器和排序器。
We look at the average frequency of contrastive connectives in the SPaRKy Restaurant Corpus with respect to realization ratings by human judges. We implement a discriminative n-gram ranker to model these ratings and analyze the resulting n-gram weights to determine if our ranker learns this distribution. Surprisingly, our ranker learns to avoid contrastive connectives. We look at possible explanations for this distribution, and recommend improvements to both the generator and ranker of the sentence plans/realizations.
