Hybrid-Context-Aware Web Service Selection Approach

Abstract

In ubiquitous network environment, Web service selection is still challenging since (1) network and resources change frequently, (2) the capabilities of devices and terminals are quite different, and (3) the data type of context information is hybrid. In this paper, we presents a context model which is described by hybrid data type such as real number, interval number, triangular fuzzy number, intuitionistic fuzzy number to describe the information of user and service with uncertainties. In order to solve the difficulties above for the first time, we also presents a Hybrid-Context-Aware Web Service Selection Approach (called HCA_WSSA) which includes context matching algorithm and optimal selection algorithm. A set of experiments demonstrate our approach is very effective.
