Figure 4:

An example of a human-preferred densification step (left) and one which is not preferred. For the left, the bottom summary is preferred because the addition of “Liverpool” and the goal-scorers is relevant. The second summary makes room with sensible compressions, such as synthesizing “a potential route back into the game” into “a comeback”. For the right, the addition of more details on “TVMonde” does not make up for the presence of an awkward fusion of entities (“cyberattack”, and “Yves Bigot”), which was a direct result of having to tighten the previous summary.
