Next, we compute the semantic similarity of the current sentence with each context representation.
we consider the element-wise product b i , cosine similarity c i and pairwise distance u i as similarity metrics: The interaction representation of sentence cp i with its left context is the concatenation of cp i , f l i , and the above similarity values (i.e., b i , c i , u i ): The interaction representation f r i for the right context rc i is computed analogously.
