There are two criteria for the selection of features for both representations: (Criterion 1) a clause should "talk" about important things, such as characters or locations (Criterion 2) a clause should contain background descriptions rather then events We hypothesize that sentences which satisfy both criteria are good candidates for inclusion in indicative summaries.
a summary that consists of such sentences would familiarize the reader with important elements of the setting of the story, but would not reveal the plot.
