• Constituents are Frequent Word Sequences among Sentences with Equivalent Predicate-Argument Structures: Unsupervised Constituency parsing by Span Matching

  Aug 2024

  Findings of ACL

  Does neural similarity capture substring-level semantic similarity? Not necessarily, substring-frequency among paraphrases might be a better choice.
