Words that tend to be used in the summaries, characterized by high KL(A ∥ G) scores, include locations (York, NJ, Iraq), people's names and titles (Bush, Sen, John), some abbreviations (pres, corp, dept) and verbs of conflict (contends, dies).
from KL(G ∥ A), we can see that it is unlikely for writers to include courtesy titles (Mr, Ms, Jr.) and relative time reference in summaries.
