An Analysis of Current State of Research Data Publication at Japanese Universities

Abstract

　In the era of Open Science, a lot of researchers committed to research data publication. This article analyzes the current state of research data publication at Japanese universities, using records of DataCite. We identify 39,128 records, in which one or more authors are affiliated with a Japanese university. More than half of the records are available on HEPData, a repository of high energy physics. We observe that the number of research data publications differ greatly depending on counting methods. In addition, the result shows that the number of research data publications has been increased in recent years.
