Title: "Service clustering with heterogeneous networks"
We construct two different networks: a network representing the collaboration relationships between services, and a network representing the usage relationships between services and users. We use graph embedding to achieve service embedding. To validate the effectiveness of our proposed method, we apply it to real data from web services and conduct clustering experiments. As a result, we achieve a 6.6% improvement in accuracy compared to existing methods.
