QoS-Aware Parameterized Semantic Matchmaking Framework for Web Service Composition

The paper presents a parameterized and highly customizable semantic matchmaking framework. The matchmaking approach on which this framework is based distinguishes three types of matching: functional attributelevel matching, functional service-level matching, and non-functional matching. The functional matching permits to eliminate web services that fail to meet the user functional requirements. The non-functional matching permits to categorize web services instances into different ordered QoS classes. A series of algorithms are advertised for the different types of matching. These algorithms are designed to support a customizable matching process that permits the user to control the matched attributes, the order in which attributes are compared, as well as the way the sufficiency is computed for all matching types.
