Aging in citation networks
In many growing networks, the age of the nodes plays an important role in deciding the attachment probability of the incoming nodes. For example, in a citation network, very old papers are seldom cited while recent papers are usually cited with high frequency. We study actual citation networks to find out the distribution T (t) of t, the time interval between the published and the cited paper. ...
متن کاملModelling Aging Characteristics in Citation Networks
Growing network models with preferential attachment dependent on both age and degree are proposed to simulate certain features of citation network noted in [1]. In this directed network, a new node gets attached to an older node with the probability ∼ K(k)f(t) where the degree and age of the older node are k and t respectively. Several functional forms of K(k) and f(t) have been considered. The...
متن کاملValuing Indirect Citations in Citation Networks using Data Fusion
Any scientific activity requires awareness of previous related activities. Citation networks are the networks in which each document is compared as a link of a chain with its previous and next documents, and the documents with the highest number of citations are considered as the most effective ones in a domain. Most of the introduced methods use direct citations for valuing the documents. One ...
متن کاملDrawing Co-Citation Networks of Corona Virus Studies
Background and Aim: The purpose of the present study is to map the coronavirus domain citation network to better understand this domain based on all other citation networks. Materials and Methods: The present study is applied in terms of purpose, and is descriptive scientometrics in terms of type, which has been done with the all-citation method. In this study, all scientific publications on ...
متن کاملLink prediction in citation networks
In this article, we build models to predict the existence of citations among papers by formulating link prediction for 5 large-scale datasets of citation networks. The supervised machine-learning model is applied with 11 features. As a result, our learner performs very well, with the F1 values of between 0.74 and 0.82. Three features in particular, link-based Jaccard coefficient , difference in...
