[目的/意义]将论文与专利相结合,建立一套整合基础研究与应用研究的研究前沿识别方法。[方法/过程]以基于关键词共现的研究前沿识别方法模型为基础,用余弦相似度算法将论文和专利相结合,并使用研究主题年龄和研究主题关注作者数量两个指标来识别研究前沿,最后在LED领域进行应用分析。[结果/结论]研究表明该方法可以识别出基于单独的论文数据或者专利数据不能识别的研究前沿,同时还可以有效地跟踪研究前沿的产生、成长、消退与消失。
[Purpose / Significance] Combining the dissertation and patents to establish a set of research frontier identification methods that integrate basic and applied research. [Method / Procedure] Based on the research frontier identification method model based on co-occurrence of keywords, the thesis is combined with patents by the cosine similarity algorithm, and two indicators are used to identify the frontier of research based on the research subject age and the research topic. , The final field of LED application analysis. [Results / Conclusions] The research shows that this method can identify the frontier of research based on the disparate essay data or patent data, and can effectively track the generation, growth, regression and disappearance of research frontier.
