The General Index provides words and phrases from millions of scientific research articles ― a massive resource for researchers ― at no cost.
What to know:
On October 7, Public Resource, a nonprofit organization, released the General Index, a repository of 355 billion words and phrases that are linked to scientific articles in which these words appear.
Although it includes articles that are behind paywalls, the index does not include more than five words per article, so it stays within publishers’ copyright restrictions.
Creator Carl Malamud aims to allow researchers to conduct large-scale analyses without being restricted to open-access articles or those they have access to.
The index is considered by some to be a major development in text mining. It allows scientists to build farther-reaching databases on specialized subjects in scientific literature.
A search engine was not created with the index, but Malamud hopes that if someone designs one, they will make it accessible to all.
This is a summary of the article “Giant, Free Index to World’s Research Papers Released Online,” published by Nature on October 26. The full article can be found on nature.com .
