Unsupervised Sentence Summarization

Unsupervised sentence summarization is a significant subtask in the field of natural language processing, aiming to automatically extract or generate the core information of a given sentence without relying on annotated data, to express its main meaning in a concise form. The goal of this task is to identify key components within sentences through algorithmic models, achieving efficient information compression and transmission. Unsupervised sentence summarization has broad application value in scenarios such as news summarization, document reviews, and information retrieval, significantly enhancing the efficiency of information processing and user experience.
