摘要
[目的/意义]通过对国内外近10年新兴主题属性量化的研究成果进行梳理,为新兴主题探测方法的改进提供参考与借鉴。[方法/过程]在梳理新兴主题相关概念的基础上,通过文本内容分析归纳新兴主题的主要属性,从单一属性量化、多属性融合量化2个方面综述目前的研究进展。[结果/结论]目前的研究主要基于文献外部特征对新兴主题的新颖性、增长性、关注度、影响力、连贯性和持续性等属性进行量化,多属性融合的量化方法包括赋权法、交点法、复杂融合法和回归法等。但现有的量化方法仍存在不足,未来需要基于多元数据来提高属性量化的全面性和准确性、探索新兴主题其他属性的量化方法、提高属性量化结果阈值设置的科学性、加强对新兴主题属性的重要性和各属性之间相关性的研究并进一步拓宽新兴主题属性量化方法所选用的领域范围。
[Purpose/Significance]By combing the research results of attribute quantification of emerging topics in recent ten years at home and abroad,it will provide reference for the improvement of the detection methods of emerging topics.[Method/Process]On the basis of combing the related concepts of emerging topics,the main attributes of emerging topics were summarized by using text content analysis,and the current research progress was summarized from two aspects:single attribute quantification and multi-attribute quantification.[Result/Conclusion]The current studies mainly quantify the novelty,growth,attentiveness,impact,coherence and persistence of emerging topics based on the external characteristics of literature,and multi-attribute quantization methods include weighting method,intersection method,complex fusion method and regression method.However,the existing quantification methods still have some shortcomings.In the future,it is necessary to improve the comprehensiveness and accuracy of attribute quantification based on multivariate data,explore the quantification methods of other attributes of emerging topics,verify the scientificity of threshold setting of attribute quantification results,strengthen the research on the importance of attributes of emerging topics and the correlation between attributes,and further broaden the research fields selected by attribute quantification methods of emerging topics.
