Coreference Applications To Summarization

In this chapter we discuss the connection between anaphora/coreference resolution and summarization. The discussion follows the summarization framework based on Latent Semantic Analysis (LSA), however, the ideas can be applied to any sentence-scoring approach. After describing the ways of combining basic (lexical) features of the summarizer with those received from the coreference resolution system we try to answer the question whether coreference resolution helps to improve the quality of selected content even if coreference resolution systems are still far from perfect. Both single-document and multi-document summarization branches are discussed. Then we focus on post-processing techniques to improve the referential clarity and coherence of extracted summaries.
