14. The classification of a WS in a given domain which is undertaken on the first layer implies that all operations that are included in the WSDL document belong to the same domain as well In the second classification layer any WSDL document that represents a WS is analysed into its operations The purpose of automatic classification of operations is to allow automated annotation of operations apart from WS classification and thus facilitate more automated ways of service invocation Architecture Positioning with respect to the other components The CAAT has been implemented as a standalone application in Java However it communicates with the OR through the CCM that operates as a middleware Also CAAT communicates to the service registry that has been implemented as a rational database system which is part of the CCM The communication between the CAAT and the CCM is performed via software interfaces that are shared between the middleware and the tool 1 2 Alignment of devices CAAT provides the capability to align ontological descriptions of devices against semantically corresponding concepts in the hyperontology in a way similar to the one applied for the alignment of web services The alignment process is undertaken by the same algorithms used for web service alignment In order to enable alignment of devices each device to be aligned should be linked to a web service interface that is used in order to control the device Typical operation

32. anual 1 Introduction The purpose of Concept Anchoring and Alignment Tool CAAT is to align the functionality of the provided services and or devices with the ontologies stored in the ontology repository i e ORATE The concepts of the same or different application areas after being aligned with other ontological concepts are able to anchor in the hyper ontology thus being ready to be used seamlessly through the tool Modifications to the aligned concepts are feasible using a user friendly functionality that hides the complexity of the conceptualised connections from the user 1 1 Alignment of Web services The tool provides a fast and easy way to classify SOAP web services based on their WSDL description files As opposed to the most common available service classification techniques which deal with the classification of WSDL documents into different application domains the technique developed for CAAT s purposes focuses on the classification of all structural elements of a WS 1 e it structures operations and their input and output parameters into different classes that describe operations of the same application domain and their parameters respectively A typical view of a WSDL file is illustrated in Figure 1 Appropriate XML structures are used to annotate the various WSDL structural elements Amongst these a WSDL file uses the operation XML element in order to annotate WS operations while the input output elements are used for
