We propose three tasks, one is from <cite>Ma, Jurczyk, and Choi [2018]</cite> , and another two tasks are new tasks designed by us. The single variable task from <cite>Ma, Jurczyk, and Choi [2018]</cite> consists a dialogue passage p, a query q which is from plot summary of the dialogue passage and an answer a. In this 1 https://github.com/emorynlp/character-mining task, a query q replaces only one character entity with an unknown variable x and the machine is asked to infer the replaced character entity (answer a) from all the possible entities appear in the dialogue passage p. This task is evaluated by computing the accuracy of predictions (see Section ).
