[Objective] This study tries to detect funding topics and their evolution based on data from NASA’s Small Business Innovation Research Program.[Methods] First, we created funding maps with two-time windows for topics of funding applications. Then, we identified areas with higher number of topics in the map. Finally, we determined the trends by comparing the changes of hotspots from the two maps.[Results] The proposed method identified the disappeared, continuous and emerging funding topics from the maps.[Limitations] The algorithm parameters and results need to be adjusted and evaluated manually.[Conclusions] The proposed method could effectively detect funding toipics and their evolution, which helps scientific management and policy decision making.
