Abstract Many university rankings have been proposed in recent decades. The remarkable divergence among various rankings leads to confusion for decision-makers. In this paper, we propose to generate a comprehensive world university ranking by aggregating existing individual university rankings. We present a new graph-based rank aggregation method by defining a competition graph of universities, in which each node represents a university and each directed edge represents an outranking relation between two universities. We propose to measure the quality of a university by the out-in degree ratio based on which we rank all universities. Moreover, We evaluate the effectiveness of our comprehensive world university ranking from the perspectives of normality and impartiality, respectively. It is shown that the aggregated ranking will be applied as a blend integrating all the information from individual university rankings and can efficiently eliminate the outliers and regional partiality as a “smoother”. Keywords Partial ranking aggregation · Consensus ranking · Competition graph · Normality · Impartiality

1 Introduction In such a fully interconnected world, new and advanced knowledge and high technology, which are in most cases imparted and incubated in higher education system, are of paramount importance for economic and social growth. Therefore, a good education in university is one of the most powerful factors for the success of individuals, regions and even nations (Kerr 2001). The high value that individuals and society place on their education broadly increases the need for information in the quality of universities and higher education systems (Docampo 2013). Candidate students and their parents are the prominent readers of university rankings for the purpose of choosing an appropriate university and acquiring a successful career (Griffith and Rask 2007; Bowman and Bastedo 2009; Çakır et al 2015). Besides, a higher position can provide universities with opportunities to promote the popularity and competitiveness, gain financial resources and attract more outstanding students (Dill and Soo 2005; Bastedo and Bowman 2011). For companies, it is also one of the most important references for recruiti
