Abstract: Nobel laureates are representative of outstanding scientists, and their research mode, once revealed, can be helpful to promote the development of science. In the study, we take the Nobel laureates in physics from 1902 to 2016 as an example. A combination of BERT semantic model and AP (Affinity Propagation) clustering is used to detect the research topics of each laureate’s papers. Then the research characteristics of laureates are analyzed from two perspectives: concentration and diffusion. The empirical analysis of the Nobel laureates in physics shows that they share a similar pattern of research behavior, which is “concentration, continuation and extension”. Although laureates will conduct multiple research topics in different periods throughout their careers, they remain focused on the Prize-winning topics while being active in their research. And with the growth of age, they would gradually expand research into other topics beyond the Prize-winning topics.
