Science mapping, at its most basic, is a combination of classification and visualization.
This map represents the relationships among and between 22 million documents – 20 million scientific and technical articles, and 2 million patents from 1996-2011. It was created by clustering the documents using a combination of citation analysis and text mining.
This map portrays the structure and dynamics of science and technology at a highly detailed level, with over 200,000 clusters of documents, each of which may last anywhere from two to sixteen years.
