Topic Model Based Hierarchical Service Recommendation
LU Yi-jin · Journal of Chinese Computer Systems · 2015
Service composition is the technique to compose and reuse existing web services,in order to create a newservice. Among them,Mashup is the most commonly used approach,and there're several websites providing supports to it. As the number of web service grows larger,it has been a serious problem on howto select appropriate services. Actually,we can recommend the next choice by provenance during composition creation. There're some step by step recommendation techniques for Mashup completion,but more or less restricted to historical information,and newservices can not be recommended. In this paper,we come up with a Topic based hierarchical service recommendation method to solve the problem. Experiments have shown its efficiency.
