First, we follow through the conventional procedure to extract a final embedding h s for a given sentence s using ASP-GCN.
we perform a subsequent run of ASP-GCN on the same sentence s to extract a final embedding, but in this instance we conceal a specific input word w. we conceal w by mapping it to the zero vector before applying ASP-GCN on s. a final embedding h (s\w) is generated for s. If h s = h (s\w) , the word w has no impact on the representation h s .
