Impactstory for researchers

Researchgate metricsMetric DefinitionRG Score It‘s a metric that measures scientific reputation based on how an author‘s

researchis received by his/her peers. The exact method to calculate this metric has notbeen made public, but it takes into account how many times the contributions(papers, data, etc.) an author uploads to ResearchGate are visited anddownloaded, and also by whom (reputation)

Reads A read is counted each time someone reads the summary or full-text, or downloads a publication from ResearchGate. Readers who are logged into the network and those who aren’t will be counted.

Citations Total number of citations to the documents uploaded to the profile. ResearchGategenerates its own citation database, and they warn this number might not beexhaustive

Profile views Total number of times your profile has been looked atImpact points Sum of the JCR impact factors of the journals where the author has published

Articles

Publications Total number of publications an author has added to his/her profile inResearchGate (full-text or no)
