We only have 30 annotated passages at our disposal, whereas Islam et al. [11] had around 300. But Islam et al.'s dataset is not annotated in as fine-grained a fashion as ours. Note also that our dataset is larger than both <cite>Sinha et al.'s</cite> 16document dataset <cite>[21]</cite> , and Das and Roychoudhury's seven document dataset [6] .
