Negative instances are paragraphs that are not likely to be narratives and do not present a plot or protagonist character, but are similar to seed narratives in others aspects.
similar to seed narratives, we require a non-narrative paragraph to contain at least four sentences with no more than 20% of sentences being interrogative, exclamatory or dialogue; but in contrast to seed narratives, a non-narrative paragraph should contain 30% of or fewer sentences that have the actantial sentence structure, where the longest character entity chain should not span over 20% of sentences.
