How many scientific papers are mentioned in policy-related documents? An empirical investigation using Web of Science and Altmetric data (1612.01822v1)

Abstract: In this short communication, we provide an overview of a relatively newly provided source of altmetrics data which could possibly be used for societal impact measurements in scientometrics. Recently, Altmetric - a start-up providing publication level metrics - started to make data for publications available which have been mentioned in policy-related documents. Using data from Altmetric, we study how many papers indexed in the Web of Science (WoS) are mentioned in policy-related documents. We find that less than 0.5% of the papers published in different subject categories are mentioned at least once in policy-related documents. Based on our results, we recommend that the analysis of (WoS) publications with at least one policy-related mention is repeated regularly (annually). Mentions in policy-related documents should not be used for impact measurement until new policy-related sites are tracked.
