During a talk on science policy, Astrophysicist Neil deGrasse Tyson shows some scientometric charts with interesting visualizations.  Specifically he shows the volume of scientific articles as a function of country of publication, as well as the rate of publication growth.  On a map of the Earth, the geographical size of each country is increased or decreased in proportion to this amount. Here is the total publications map:  The USA, Europe and Japan dominate.   Here is the rate of growth map:  Europe and Japan are both growing strong, while China is rapidly on the rise, and the USA definitely growing much […]

Last month, we participated in a symposium on Technology Forecasting at the Library of Congress.  Here is the poster we displayed at our vendor booth showing our approach to Co-Affiliation Collaborative Mapping.

We’re experimenting with different databases and analytical approaches.  Below is a bipartite assignee-applicant network that shows how companies are linked together through shared inventors. Database:  This data comes from a single week of patents granted by US Patent and Trademark Office (USPTO) database.  This is a very small part — there are roughly 7000 patents granted per week by the USPTO alone.  Note that this does not necessarily mean these patents were filed in the same week since the review time does vary. Analytics:  The network map was created by linking every inventor (in blue) with the associated assignee (in […]
