Center node: "improving a strong neural parser with conjunction specific features"
  Abstract: While dependency parsers reach very high overall accuracy, some dependency relations are much harder than others. In particular, dependency parsers perform poorly in coordination construction (i.e., correctly attaching the "conj" relation). We extend a state-of-the-art dependency parser with conjunction-specific features, focusing on the similarity between the conjuncts head words. Training the extended parser yields an improvement in "conj" attachment as well as in overall dependency parsing accuracy on the Stanford dependency conversion of the Penn TreeBank.

Connected through hyperedge HE-1 (induced by source paper "non projective dependency parsing via latent heads representation lhr"):

    - "encoder decoder shift reduce syntactic parsing"
