How far we can go with extractive text summarization? Heuristic methods to obtain near upper bounds

作者：

Highlights：

• We propose 9 heuristics to construct near upper bounds for extractive summarization.

• The proposed methods are faster and have close results to the exhaustive search.

• We construct the sentence-based and word-based near upper bounds for 5 different corpora.

• We evaluate 6 general extractive summarization methods across the 5 corpora.
