There have been several reference recommendation systems (Huang et al., 2015;Caragea et al., 2013;Huang et al., 2014;Tang et al., 2014;Ren et al., 2014;Meng et al., 2013;Huang et al., 2012) for scientific articles but all of them either use the the text of the cited paper or the underlying citation network which makes these systems inappropriate to be used as baselines to compare with WikiRef.
we propose some standard baselines to ascertain the importance of each step in our approach.
