The web of the future will require automated tagging of equivalent or similar services in support of service discovery and the selection of appropriate alternatives in case of failure. Code similarity detection tools, or clone detectors, provide a mature and scalable method of identifying these kinds of similarities and can be used to assist in this problem. However, they require a set of units to be compared; something to which the most popular description language, WSDL (Web Service Description Language), does not lend itself. First, each WSDL description can contain more than one operation description, which does not provide the granularity we need to compare services on the operation level. Secondly, these operation descriptions are mixed together throughout the file, often sharing some common elements. This thesis describes a technique for extracting the elements of each operation description and consolidating them into a self-contained unit using TXL, a source transformation language. These units, referred to as Web Service Cells or WSCells (pronounced “wizzles”), can then be used by similarity detectors to search for similarities. We describe a modified architecture to the NICAD clone detector to support the creation of WSCells, and the implementation of a special WSDL extractor we used to emulate this modification in its absence. / Thesis (Master, Computing) -- Queen's University, 2011-10-04 09:33:36.932
