Web Service Selection in Trustworthy Collaboration Network

摘要

Most of trustworthy web service selection simply focus on individual reputation and ignore the collaboration reputation between services. To enhance the collaboration trust during web service selection, a reputation model called collaboration reputation is proposed. The collaboration reputation model is built on web service collaboration network (WSCN), and it provides the elimination mechanism of false web service to guarantee the trustworthy web service selection. The collaboration reputation can be assessed by invoking reputation and invoked web service. Then web service selection based on collaboration reputation in WSCN is designed. Experimental results confirm that our model has a better ability to perform service combination. With the collaboration reputation guaranteed, the selection efficiency and the solution's trustworthiness are both increased.
