A Social Network Analysis of World Cities Network

Social network presents a variety of data in a network format. Networks may vary according to subjects. Social network analysis (SNA) can be done in different ways. There are various measures available to evaluate and make a conclusion. Some work has been done in the area of measure analysis, finding the critical nodes in the network, evaluation, and comparison of graph centralities. In this paper, an analysis related to the world cities network has been done. World city network presents a bipartite kind of graph. The parameters and methodologies for analysis are dependent on what type of data, a graph is representing. It also depends on the kind of a graph obtained from the network. World city network can be studied for analysis purpose. This analysis is carried out with several centrality measures. Cities connected with more service firms, cities connected to the firms having attachments to larger cities, which firm is closest to all other cities, etc. are some details that can be obtained from the analysis.
