Instructions: 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.
Input: We define the STransE score function $\mathcal {R}$1 as follows:

$ f_r(h, t) & = & \Vert extbf {W}_{r,1} extbf {h} + extbf {r} - extbf {W}_{r,2} extbf {t}\Vert _{\ell _{1/2}} $

using either the $\ell _1$ or the $\ell _2$ -norm (the choice is made using validation data; in our experiments we found that the $\ell _1$ norm gave slightly better results).
Question: What scoring function does the model use to score triples?
Output:
$ f_r(h, t) & = & \Vert extbf {W}_{r,1} extbf {h} + extbf {r} - extbf {W}_{r,2} extbf {t}\Vert _{\ell _{1/2}} $
