This paper introduces a link prediction method based on the strength and prominence of seed node pairs, referred to as the strength prominence index. In this method, we get a consistent score for any pair of nodes, regardless of whether they share a common neighbour. Several key characteristics have been identified. In our experiments, we used three well-known estimators to evaluate the accuracy of link prediction algorithms: precision, area under the precision-recall curve, and area under the receiver operating characteristic curve. A comparative study with existing methods is also presented, supported by relevant graphs and tables. Validation using Facebook data sets demonstrates the effectiveness of the proposed method.Springer20252025-06-12 04:06:00Neznano22641UDK: 519.876:316.7ISSN pri članku: 2198-6053DOI: 10.1007/s40747-025-01925-6COBISS_ID: 239073539sl© The Author(s)
