The task of determining the citation span for a citation c and a paragraph p, respectively ⟨p, c⟩ (or simply p c ), is subject to the citing paragraph and the citation content.
we refer with citation span to the textual fragments from p which are covered by c. The fragments correspond to the sequence of subsentences S(p) = ⟨δ 1 1 , δ 2 1 , .
