In the Explore maps, each paper is given a relevance score between 0-100%, which indicates how closely the result matches the search. The relevance score is connected to Iris.ai’s document fingerprint matching that uses the WISDM similarity metric. 

The default maximum relevance threshold for Explore map results is set at 95% in order to avoid duplicates of papers. You can change the threshold with the filter tool to widen or narrow down the relevance range.
