摘要 命名实体识别是文本信息处理的重要基础,已经逐步成为自然语言处理的一项关键技术。其基于规则、统计、机器学习的研究方法及成果,都推动了自然语言处理研究的发展,促进了自然语言研究与应用的紧密结合。本文回顾了命名实体识别技术的发展过程,分析了主要的方法和技术,并展望了未来的发展趋势。 Named Entity Recognition (NER), as the important foundation of Text Processing, has become a key technology of Natural Language Processing (NLP). It has made a great impetus to the research of NLP with its method and result. Moreover, NER has built a more effective connection between NLP theories and applications. This paper will review the history of the research, analyze the methods and technologies and give a view of the future of NER.
