The W3C Recommendation for Semantic Annotations in WSDL and XML Schema (SAWSDL) defines an extension that can help to disambiguate the description of Web Services during automatic discovery and composition. In this way, SAWSDL is useful to facilitate the grounding stage when annotating Web Services. Despite SAWSDL does not specify a language to represent the semantic models for annotations, most of the times, ontologies are used to do it. In this work we propose a mechanism to automatically enrich SAWSDL annotations using concepts from different ontologies. As result, we provide a method for helping experts to annotate web services according to the SAWSDL recommendation.
