Project Description:
This work demonstrates an approach to map the dynamics of scientific knowledge via analysis of the complete set of papers published in the Proceedings of the National Academy of Science (PNAS) in the years 1982-2001. Data analysis techniques are applied to citation data within this corpus to analyze and visualize highly frequent words as well as sudden increases in the usage patterns of words, called 'bursts'.
