A review of Fuzzy Based QoS Web Service Discovery

Recently, web service has become an important issue for developers. Selecting a specific service is a crucial task. Some approaches develop extensive description and publication mechanisms while others use syntactic, semantic, and structural reviews of Web service specifications. It is very crucial for finding the most suitable web service from a large collection of web services for successful execution of applications. In many cases, the value of a QoS property may not be precisely defined. Recently, fuzzy is considered as the dominant approaches in Web services which can deal with fuzzy constraints have been proposed. Therefore fuzzy logic can be applied to support for representing such imprecise QoS constraints. In this paper, we will present an overview which focus on developing fuzzy-based approach for Web service discovery. This paper also describes the web service challenges on fuzzy mechanism that summarized and analyzed in order to assess their benefits and limitations.
