Purpose/Significance To identify research frontiers in the field, so as to assist scientific researchers to effectively select and track key research topics, and help research management decision-makers to dynamically adjust policy orientation. Method/Process Taking 37 927 pieces of high-impact journal document references and highly cited document references from the WOS database which published in the period of 2012—2022 as the data samples, BERTopic is used to extract topics,a multi-dimensional indicator research frontier recognition model is constructed, and different types of research frontiers in the field are identified from multiple dimensions. Result/Conclusion The proposed model identifies 9 hot research frontier topics, 14 emerging research frontier topics, 13 potential research frontier topics and 1 declining research topic in the field of oncology, which is effective.
