中文摘要 |
purpose: this study aims to answer the question to what extent different types of networks can be used to predict future co-authorship among authors. design/methodology/approach: we compare three types of networks: unweighted networks, in which a link represents a past collaboration; weighted networks, in which links are weighted by the number of joint publications; and bipartite author-publication networks. the analysis investigates their relation to positive stability, as well as their potential in predicting links in future versions of the co-authorship network. several hypotheses are tested. findings: among other results, we find that weighted networks do not automatically lead to better predictions. bipartite networks, however, outperform unweighted networks in almost all cases. research limitations: only two relatively small case studies are considered. practical implications: the study suggests that future link prediction studies on co-occurrence networks should consider using the bipartite network as a training network. originality/value: this is the first systematic comparison of unweighted, weighted, and bipartite training networks in link prediction. |
