摘　　要：[目的 /意义]基于AToT模型的多维动态演化分析,不仅可以全面地了解技术主题的动态变化,把握不同时期不同企业的技术布局变化,还可以掌握产业链各环节的技术发展状态,为企业创新提供强有力的决策支持。[方法 /过程]首先提取专利文献摘要中的名词或者名词短语,然后利用AToT模型揭示专利文献中隐含的主题演化及专利权人的技术关注点,最后结合产业链信息把握产业各个环节的发展状况。[结果/结论]实验结果证明,该方法能够高效地分析专利的内容,揭示企业技术主题的动态演化过程。[Purpose/significance ] Multi-dimension evolution analysis based on the AToT model could not only pro- vide thorough insights into the evolution process of technology topics, mastering technological composition trends among in- dustries in different periods, but have advantages in analyzing the technological development process in each tache of the industry chain, laying solid foundation for industrial innovation. [ Method/process] This paper revealed the latent tech- nology topics and technological attention of patent-owners through keywords and phrases which were extracted from ab- stracts in each patent document, and showed deep insight into the technological development status with industry chain in- formation. [ Result/conclusion] The experiment turns out that the method provided in this paper could not only analyze the content of patents effectively, but reveal the dynamic evolution process of enterprise technological topics.
