Abduction 讲究的是根据 “结果” 与 “部分原因” 推导不全另一部分原因。如:我看到 a 和 b 走在一起,根据他们本来不是很熟且今天是 5.20,我合理推断这是因为 a 对 b 表白成功导致的。Biabduction 则是连 “结果” 也不知道全貌: 首先根据 abduction 得出 anti-frame,然后再根据 A 与 anti-frame 推导 frame。 |

在完成对上述 logic rules 的解释后,文中给出了 Bi-Abduction 的算法,其实很简单: Frame 可以理解成正常的推导,根据 Abduction 就是上面提到的那样。因此,Bi-Abduction 是: |
