Hello, I have a question about the vector p of paper, how does a sentence get the dependency relationship of its parents? Is this arrow pointing artificially labeled? 图片

We use a parser (e.g. CoreNLP) to annotate each sentence with its dependency tree.

When the parent is split into multiple subwords, we use its middle position as described in the paper. Code to do this is here.
