(main ent(T1-root)!=main ent(T2-root)) Output: a new tree T3 where the root node has two immediate children such that 1. pred(T3-root)←"Same" ∧ main ent(T3-root)← a unique element 2. left child(T3-root)←T1 ∧ right child(T3-root)←T2 In our work, we thus developed a method that would choose a text plan on principled reasoning concerning the resulting text.
we looked to balance sentence complexity and the number of sentences in the generated text.
