In this paper we explore the benefits from and shortcomings of entity-driven noun phrase rewriting for multi-document sum- marization of news. The approach leads to 20% to 50% different content in the sum- mary in comparison to an extractive sum- mary produced using the same underlying approach, showing the promise the tech- nique has to offer. In addition, summaries produced using entity-driven rewrite have higher linguistic quality than a comparison non-extractive system. Some improvement is also seen in content selection over extrac- tive summarization as measured by pyramid method evaluation.
