One can thus use mapping Φ all,1,⊕ in lieu of Φ all,1,⊕ : It should be clear that Φ all,1,⊕ provides a normalized version of Φ all,1,⊕ as this latter mapping amounts to weighted versions of the former: Through the comparative framework described in section 3, our objective is to assess the usefulness of different vectorial representations for pairs of discourse segments.
we want to establish whether dense representations are better than sparse ones, and whether certain word pairs are more relevant than others, which resource and which combination schemes are more adapted to the task, and, finally, whether standard features derived from external databases are still relevant in the presence of dense representations.
