Aligning texts and their multi-document summaries is the task of determining the correspondences among textual segments in the texts and in their corresponding summaries. The study of alignments allows a better understanding of the multi-document summarization process, which may subsidize new summarization models for producing more informative summaries. In this paper, we investigate some approaches for text-summary sentence alignment, including superficial, deep and hybrid approaches. Our results show that superficial approaches may obtain very good results.
