基于长尾关键词的领域新兴前沿探寻模型构建研究

Research on the Construction of Emerging Frontier Exploration Model Based on Long-Tail Keywords

[目的/意义]以目前领域前沿识别的研究为基础,从生命周期角度出发,尝试从被常规研究所忽略的长尾关键词中探寻领域新兴前沿,提升领域前沿识别的时效性。[方法/过程]该文以新颖性为筛选依据,以成长力和催化力两个指标为依托,构建领域新兴前沿探寻模型。以知识服务领域为例进行实证分析。[结果/结论]实验结果表明,新的探寻模型具有较高的准确率、可靠性以及前瞻性。

[Purpose/Significance] The identification of the frontier of the field has a direct role in scientific research, and it is an indispensable part of the process of technological innovation. Considering research status of the identification, the writer uses "Long-Tail key words" to explore and find new frontiers in the field, which are always ignored by conventional research.[Method/Process] Based on the novelty, growth and catalytic characteristics of the emerging frontiers of the field, the emerging frontier exploration model is constructed, and the empirical analysis is conducted by taking the knowledge service field as an example.[Result/Conclusion]The experimental results show that the emerging frontier exploration model can advance the detection time of the frontier of the field, and has high accuracy and reliability.
