For this, we focus on the non-restrictive appositives and relative clauses, which often carry noncritical information (Conroy et al., 2006;Wang et al., 2013) and can be automatically detected based on comma usage patterns.
a sentence contains a non-restrictive appositive if i) it contains two commas, and ii) the word after first comma is a possessive pronoun or a determinant (Geva et al., 2019).
