Fig. 2From: Discovering themes in biomedical literature using a projection-based algorithmFrequency of top 5, 10, and 20 topic terms. The size of m is varied from 2 to 40 and for every value of m we compute the average frequency of the top 5, 10 and 20 subject terms. We observe that as the size of m increases, the frequency of the top terms also increases, suggesting that the algorithm converges to a more general themeBack to article page
