The Evolution of Degree Distribution, Maximum Cliques and Maximum Independent Sets of Company Co-Mention Network over Time
Authors: , , , , , ,
Abstract: The main subject of our research is the characteristics and features of the economic and finance news flow. In this paper we construct company co-mentions network as a graph in which nodes serve as the world’s largest companies mentioned in financial and economic news flow. We link two nodes if two companies were mentioned in the same news item. We construct company co-mention networks for 72 consecutive monthly periods to analyze the dynamics of the structural properties of the company co-mentions network over time. These structural properties are examined based on different graph characteristics such as the distribution of the degrees of the vertices in this graph as well as maximum clique and maximum independent sets sizes. Some conclusions are derived with respect to the dynamics of the evolution of the company co-mentions network over time.
