| 摘 要： | 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。

| Abstract: | Purpose/significance] This research tries to combine scientific papers with patent, and establish a reasonable research fronts identifying method model which integrates basic research and application research. Method/process] Based on the methods of identifying research fronts based on keywords co-occurrence, using cosine similarity method to combine scientific papers with patent,and using two indexs of research topic ages and authors number with the concern for identifying research topics to identify the research fronts.Result/conclusion] The results indicate that the method not only can identify the research fronts which can't be identified only based on scientific papers or patent but also track the generation,growth,decline, and disappearance of research fronts. |
