3.3 Automatic summarization evaluation
Automatic evaluation of summary quality is impor-
tant for the research of document summarization as
it avoids the labor-intensive and potentially inconsis-
tent ... summarization
can be viewed as a problem of submodular function
maximization. We also in this section show that many
standard methods for summarization are, in fact, al-
ready performing submodular function ... constant-factor approximation
guarantee does not apply in this case.
When scoring a summary at the sub-sentence
level, submodularity naturally arises. Concept-based
summarization (Filatova and Hatzivassiloglou,...
