The present paper describes the main characteristics and components of the tool developed for integrating the definition of profiles for semantic web services. This tool is based on the languages DAML-S and OWL-S and it includes the ontology visualization and consistency verification that specify the concepts a web service interacts with. Starting from a service description interpreted by a computer and by the means used for accessing the service, it is possible to find out which software agents use the service. The tool can generate information in different formats, such as the SVG format proposed by the W3C, for representing graphic information based on XML. The tool was developed in Java language and is being used for the visualization of ontologies and for the semantic description of services in traffic information systems that the LISITT group (Laboratorio Integrado de Sistemas Inteligentes y Tecnologías de la información de Tráfico) developed at the Robotics Institute at the University of Valencia.
