Supervising the Centroid Baseline for Extractive Multi-Document Summarization
Simão Gonçalves, Gonçalo Correia, Diogo Pernes, Afonso Mendes
The centroid method is a simple approach for extractive multi-document summarization and many improvements to its pipeline have been proposed. We further refine it by adding a beam search process to the sentence selection and also a centroid estimation attention model that leads to improved results. We demonstrate this in several multi-document summarization datasets, including in a multilingual scenario.
