TL;DR

A keyword map of the labels used by the scientists registered in the Google Scholar Citations database from December 2011 is introduced and it is suggested that GSC would in the future be an accurate source to map Science because it is based on the labels that scientists themselves use to describe their own research activity.

Abstract

This paper introduces a keyword map of the labels used by the scientists registered in the G oogle S cholar C itations ( GSC ) database from D ecember 2011. In all, 15,000 random queries were formulated to GSC to obtain a list of 26,682 registered users. From this list a network graph of 6,660 labels was built and classified according to the Scopus Subject Area classes. Results display a detailed label map of the most used (>15 times) tags. The structural analysis shows that the core of the network is occupied by computer science–related disciplines that account for the most used and shared labels. This core is surrounded by clusters of disciplines related or close to computing such as I nformation S ciences, M athematics, or B ioinformatics. Classical areas such as C hemistry and P hysics are marginalized in the graph. It is suggested that GSC would in the future be an accurate source to map S cience because it is based on the labels that scientists themselves use to describe their own research activity.
