With the rapid increase and wide application of Web APIs and Mashup services,the relationship among Web APIs,Mashup services and their function tags become very complex and constantly evolve,result in forming a large network of services.And the characteristics research on this network by using complex network has an important significance,which will greatly promote service discovery and composition.In this paper,we conduct the empirical study to the large-scale Mashup service network.Firstly,Web APIs,Mashup services and tags are crawled from ProgrammableWeb website and Mashup service network prototype system is developed,and Mashup service homogeneous networks and heterogeneous networks are built.Then,we use degree and degree distribution,average shortest path length and clustering coefficient of complex network,to measure and analysis the Mashup service homogeneous networks and heterogeneous networks.The experimental results show that the Mashup service network has the characteristics of “small world” and “scale-free”,which will provide some guidance to service discovery and composition in Web API or Mashup.
