On the Topological Landscape of Web Services Matchmaking

Despite the rapid development in web services technologies, there has been little study on the public web services from network analysis perspective. To address this, in this paper, we have performed a topological study on various web service networks using real-world data sets. We first propose a flexible framework by which we can study semantic web services network “matchmaking” in a unified manner. Under the matching framework, then, we have conducted extensive experiments to study the characteristics of various web services networks. By and large, publicly available web services networks exhibit the typical characteristics of small world networks well and power law like distributions to some extent.
