Scientists are increasingly using the Web to exchange, share, and accumulate/identify knowledge. The use of the Web by scientists is a field of growing interest. Thus it made us question, who is using these Web platforms? All scientists, specific groups/ages/disciplines of science. With a group of computer scientists within the Network Institute we developed a method and tool to identify a set of known scientists to able to reflect on the representativeness of Web studies of scientists online. This work was recently presented at the Sixth Chinese Semantic Web Symposium (CSWS2012) and the First Chinese Web Science Conference (CWSC2012) in Shenzhen, China. And will be published shortly in the conference proceedings, for now you can find the publication here.
