How to create a WSMO-based semantic service without knowing WSML

In order to make accessible new Semantic Web Services technologies to the end users, the level of tools supporting these technologies should be significantly raised. The paper presents such a tool - an INFRAWEBS Designer a graphical ontology-driven development environment for creating semantic descriptions of Web services and goals according to WSMO Framework. The tool is oriented to the end users - providers of Web services and semantic Web services applications, who would like to convert their services into WSMO based semantic Web services. The most character features of the tool intensive use of ontologies, automatic generation of logical description of a semantic service from graphical models and the use of similarity-based reasoning for finding similar service descriptions to be reused as initial templates for designing new services are discussed.
