So far, research evaluation has been very important as a means for deciding academic tenure, awarding research grants, tracking the evolution of scholarly institutions, and assessing doctoral students (King, 1987). However, this effort has been limited by the lack of findability and accessibility of bibliographic databases allowing such an assessment and the legal and financial burdens toward their reuse (Herther, 2009). By the Internet age, scholarly publications became issued online in an electronic format allowing the extraction of accurate bibliographic information from them (Borgman, 2008) as well as the tracking of their readership, download, sharing, and search patterns (Markscheffel, 2013). Online resources called bibliographic knowledge graphs have consequently appeared, providing free bibliographic data and usage statistics for scholarly publications (Markscheffel, 2013).
