TASK DEFINITION: In this task, you will be presented with a context from an academic paper and you have to write an answerable question based on the context. Your questions can be extractive, abstractive, or yes-no questions.
PROBLEM: We map each relation type $R(x,y)$ to at least one parametrized natural-language question $q_x$ whose answer is $y$ .

SOLUTION: How is the input triple translated to a slot-filling task?

PROBLEM: The ensembles were formed by simply averaging the predictions from the constituent single models.

SOLUTION: How does their ensemble method work?

PROBLEM: Baselines. As none of the existing KBC methods can solve the OKBC problem, we choose various versions of LiLi as baselines.

Single: Version of LiLi where we train a single prediction model INLINEFORM0 for all test relations.

Sep: We do not transfer (past learned) weights for initializing INLINEFORM0 , i.e., we disable LL.

F-th): Here, we use a fixed prediction threshold 0.5 instead of relation-specific threshold INLINEFORM0 .

BG: The missing or connecting links (when the user does not respond) are filled with “@-RelatedTo-@" blindly, no guessing mechanism.

w/o PTS: LiLi does not ask for additional clues via past task selection for skillset improvement.

SOLUTION:
What baseline is used in the experiments?
