In this brief announcement, the author shares an intriguing discovery about using the cosine similarity approach from explore2.marginalia.nu as an alternative to the link graph in the PageRank algorithm. The PageRank algorithm simulates where a random visitor would end up if they clicked on links on websites, but its performance has been declining over time due to changes in website linking and manipulation techniques. However, this new approach appears to be highly resistant to existing manipulation techniques and stays focused on the relevant topic. The post also provides additional resources for further exploration.
