Query-focused multi-document summarization using hypergraph-based ranking

作者:

Highlights:

• We propose a novel hybrid method to capture group relation of sentences.

• We cluster sentences with a KL-divergence based on word-topic distribution.

• We proposed a vertex reinforcement random walk process in a hypergraph model.

• The process simultaneously consider the query similarity, the centrality and the diversity of sentences.

• We implement our framework and verify improvement over appropriate baselines.
