Abstract The detection of emerging topics is a research area that has been increasingly attracting numerous scholars' attention. An extensive knowledge of the dynamics of emerging topics in science and technology not only provides our government with support to make decisions on policies regarding guidelines for scientific research in order to improve profits from financial investments on scientific research and to accelerate the development of science, but can also offer scientific professionals directions for promising research areas that can help them dedicate themselves to scientific discovery. Although we used summaries of relevant literature on this topic that were published in international core journals, we found no clear definition for “emerging topic” or its related terms. The resulting methodology, therefore, has some limitations to conquer. Indicators for identifying emerging topics vary across the literature. Based on our investigation on the studies in this area, we proposed a definition for “emerging topic” and identified its attributes. Moreover, we also compared “emerging topic” with its related terms and identified some areas worth noting when detecting emerging topics in scientific research. Finally, we presented four aspects of this topic that require further study in the future.
