Sub-topic Segmentation in Multi-document
Xiaoyan Yun, Wei Teng · 2012
The similar sentences in multi-document set are combined into one class, and each class is one sub-topic.Describing the sub-topics from the perspective of understanding makes the multi-document summarization become the one with greater coverage and less redundancy.This paper presents a sub-topic segmentation method based on maximum tree algorithm.And based on sentences similarity matrix, maximum tree is calculated, as well as the sub-topic segmentation is realized through the analysis of the different communities for the sub-topic.The experiment shows that the method achieves the desired result.
