| 把握学科研究前沿是科研人员和科研管理者十分关注的问题，本文提出从学科研究热点中识别研究前沿的方法，帮助研判学科未来发展方向，以期为学科发展决策提供参考。首先基于高被引论文，采用共被引聚类算法来识别研究主题，从中遴选出研究热点；再获取与研究热点相关联的施引文献，采用突变词检测算法结合专家研判来识别学科研究前沿；运用此方法，以光学学科为例，从遴选出的9个光学研究热点中识别出若干学科研究前沿，并借助资料验证法对识别结果的可靠性进行评估。结果表明：本文提出的方法具有一定的可行性、前瞻性和可靠性，识别结果能够为决策者提供参考。 |
| 英文摘要: |
| Grasping discipline research fronts is a matter of great concern to researchers and scientific research managers. In this paper, research fronts come from research hotspots. This study aims to help judge development direction of discipline and provide a reference for decision-making of discipline development. Based on highly cited papers, the co-citation analysis method is used to identify research topics and hotspots. In addition, citing papers related to the research hotspots are obtained. This study proposes a burst detection algorithm and expert judgment based on citing papers for identifying research fronts. Several research fronts are identified from nine optical research hotspots. This study evaluates the reliability of the recognition results with data verification method. The results show that the method proposed in this study is feasible, forward-looking and reliable, which means the identification results can provide a reference for decision makers. |
