EntailmentBank Dataset

EntailmentBank is a dataset that contains multistep entailment trees. At each node in the tree (typically) two or more facts compose together to produce a new conclusion. Given a hypothesis (question + answer), three increasingly difficult explanation tasks are defined: generate a valid entailment tree given (a) all relevant sentences (the leaves of the gold entailment tree) (b) all relevant and some irrelevant sentences (c) a corpus.

EntailmentBank 是一个包含多步蕴涵树的语料库。在树中的每个节点（通常）由两个或更多事实组合在一起，以生成一个新的结论。针对一个假设（问题加答案），定义了三个难度递增的解释任务：给定（a）所有相关句子（金牌蕴涵树的叶子节点）、（b）所有相关句子和部分无关句子、（c）一个语料库，生成一个有效的蕴涵树。
