摘要
自动关键短语抽取是知识抽取和信息检索等信息技术的关键步骤,当前已经被广泛研究多年,但是和许多自然语言处理任务的性能相比,现有抽取算法的性能依然很低下。对自动关键短语抽取方法进行综述,并对其未来研究发展进行展望,为进一步自动抽取高质量的关键短语提供良好借鉴。
Automatic keyphrase extraction is a key step knowledge extraction and information retrieval of information technology, the current has been extensively studied for many years, but many properties as compared to natural language processing tasks, the performance of exist-ing extraction algorithm remains low down. Reviews phrase for automatic extraction methods, and prospects for its future research and de-velopment, to provide a good reference for further automatically extract keyphrases of high quality.
