Abstract  This paper firstly creates Medical Subject Headings (MeSH) feature vector for medical literature, then searches for the latest cited times of each paper after published two years, which serves as the indicator for hot papers. Using a genetic program, a group of MeSH terms representing the content of hot papers are extracted. The method is tested on the topic of neoplastic stem cells,and the results from term frequency analysis are served as a baseline. The outputs of two methods are evaluated by domain experts,and the results show that genetic algorithm based method has a better performance than term frequency based method.
