The Impact of Boundary Spanning Scholarly Publications and Patents
Authors: Xiaolin Shi, me, Belle Tseng, Gavin Clarkson
Human knowledge and innovation are recorded in two media: scholarly publication and patents. These records not only document a new scientific insight or new method developed, but they also carefully cite prior work upon which the innovation is built.


We quantify the impact of information flow across fields using two large citation dataset: one spanning over a century of scholarly work in the natural sciences, social sciences and humanities, and second spanning a quarter century of United States patents.
We find that a publication’s citing across disciplines is tied to its subsequent impact. In the case of patents and natural science publications, those that are cited at least once are cited slightly more when they draw on research outside of their area. In contrast, in the social sciences, citing within one’s own field tends to be positively correlated with impact.
The paper came out last week. PLoS One has these neat features where readers can rate the article, leave comments in general, or comment on particular parts of the text. So far… nothing. I’m a bit bummed. Either no one has noticed our potentially controversial article, or it’s not as controversial as I had assumed.

Sorry, the comment form is closed at this time.
