The document describes a 4-step process for evaluating the accessibility of a web service: 1) The evaluator inputs the web service's WSDL file and the tool parses it to extract information. 2) The tool automatically evaluates some guidelines based on the WSDL. 3) The tool aligns the service's operations to "ideal operation" elements in an accessibility ontology to understand the service's functionality. 4) Additional guidelines are evaluated based on the service's declared functionality from step 3. The evaluator then manually evaluates any remaining guidelines.
