摘　　要：[目的/意义]结合外部学科属性及内部主题演化开展学科交叉发展态势分析,有助于捕获领域发展前沿,推进交叉创新发展。[方法/过程]本文基于目标领域的全景与突破性研究,通过构建学科交叉共现网络开展外部学科属性演化分析,依托BERTopic模型挖掘学科交叉内部主题并开展内部主题演化分析,进而开展全景与突破性研究的对比分析。[结果/结论]本文以生物医学工程研究为例,在外部学科属性层面,学科交叉程度日益加强,且突破性研究的关键子网络是全景研究的子集,前者更关注医学而后者更关注工学;在内部主题演化层面,学科交叉演化速度日趋加快,前者演化速度较快而后者演化速度相对稳定,且二者各有不相交的5个和3个前沿主题。基于外部学科属性与内部主题演化揭示全景与突破性研究的学科交叉发展态势有助于促进交叉创新。[Purpose/Significance]This paper aims to analyze the development trend of interdisciplinary by combining the external discipline attributes and internal topic evolution.It is helpful to capture the development frontier of the field and promote the development of interdisciplinary innovation.[Method/Process]Based on the overall research and breakthrough research of a target field,this paper firstly constructed the interdisciplinary co-occurrence network to analyze the evolution of external discipline attributes.Secondly,this paper employed the BERTopic model to extract the interdisciplinary internal topics and analyzed the evolution of internal topics.Finally,this paper conducted a comparative analysis of overall research and breakthrough research.[Result/Conclusion]This paper takes biomedical engineering research as an example,in terms of external discipline attributes,the degree of interdisciplinary is increasing,the key interdisciplinary sub-network of breakthrough research is a subset of overall research.The former pays more attention to“Medicine”while the latter pays more attention to“Engineering”.In terms of internal topic evolution,the speed of interdisciplinary evolution is accelerating,the former is faster and the latter is relatively stable.The two have 5 and 3 promising topics that do not intersect.Based on the external discipline attributes and internal topic evolution,revealing the interdisciplinary development trend of overall and breakthrough research is helpful to promote interdisciplinary innovation.
