In this task, you will be presented with a context from an academic paper and a question separated with a 
. You have to answer the question based on the context.

An extrinsic evaluation was carried out on the task of Open IE BIBREF7. 
 Question: Is the semantic hierarchy representation used for any task?
Yes, Open IE

We evaluate our model in a simulated binning task in which the robot is tasked to place a cube into a bowl as outlined by the verbal command. Each environment contains between three and five objects differentiated by their size (small, large), shape (round, square) and color (red, green, blue, yellow, pink), totalling in 20 different objects. Depending on the generated scenario, combinations of these three features are necessary to distinguish the targets from each other, allowing for tasks of varying complexity. 
 Question: What simulations are performed by the authors to validate their approach?
a simulated binning task in which the robot is tasked to place a cube into a bowl as outlined by the verbal command

To report the result for answer selection, MAP and MRR are used; however, the answer triggering task is evaluated by F1-score. The result for MULT Method is reported in Table. 1. 
 Question: Is accuracy the only metric they used to compare systems?

No
