科学技术新兴技术主题识别研究

Identification of topics on emerging technology

目的:挖掘科技文献中的新兴技术主题。方法:构建新兴技术主题识别研究框架。采用隐含狄利克雷分布(LDA主题模型结合熵权法对新兴技术主题进行识别。结果:识别出了新型比色检测技术、新型荧光检测技术和生物检测技术3个新兴技术主题。结论:新兴技术主题识别研究框架可有效识别科技文献中的新兴技术主题。

Objective To mine the topics on emerging technology from scientific and technological literature.Methods The study architecture for identifying the topics on emerging technology was established.The topics on emerging technology were identified according to the LDA topic model.Results The colorimetric detection technique,new fluorescence detection technique and biological detection technique were identified as three topics on emerging technology.Conclusion The study architecture for identifying the topics on emerging technology can effectively identify the topics on emerging technology from scientific and technological literature.
