A team at Indiana University created Scholarometer to "facilitate citation analysis and help evaluate the impact of an author's publications." The crowdsourced data created through the Scholarometer platform is available through the Scholarometer API that allows developers to track certain authors through name, citation, disciplines, relevance, and other metrics.
Kippt, designed to make information workflow and archiving effortless, has launched a new API alongside a developer site and app gallery. The new, publicly available API simply opens up the existing Kippt API that continues to power the Kippt web service. Instead of pushing Kippt as a standalone product, the Kippt team hopes that the Kippt API will encourage developers to develop apps based on the Kippt platform.
