Text Summarization Based on Sentence Clustering with Rhetorical Structure Information

摘要

We propose a text summarization approach that clusters text units before extracting summary sentences. Text units are formed by combining sentences based on rhetorical structure information. The rhetorical structure information we use is the one immediately recognizable at the surface level, making this approach language independent as much as possible. Experiments conducted with both Korean and English text collections show that the approach improves the quality of summarization.
