Attention decay in science
作者：
Highlights：
• Attention devoted to individual papers, can be measured by their citation counts.
• The attention decreases rapidly within a few years of the paper's publication.
• Nowadays, this decay is becoming faster, signaling that papers are forgotten quickly.
• This is a consequence of the exponential growth in the number of scientific papers.
• Researchers find it increasingly difficult to track all the relevant publications.
