On Visualization of Journals Reference Network Based on Force-Directed Layout Algorithms
Abstract:
Visualization of a journal network is to show the topology of journals reference in a graphic way so as to observe their interaction and importance. A reference network was drawn from the force-directed algorithm, and then compared to the degree centrality and betweenness centrality of the network, and analyzed with their compound influencing factor and core index by Pearson correlation coefficients at last. The results show that the force-directed layout algorithm can effectively reflect the referential status and relations of the library and information (LI) journals, and the importance of a journal can be determined from the layout in a visual and direct way.
