Szukana fraza: [Abstract = "These models are used as the source for a model\-driven method that applies several transformations to conceptual models generating the rule\-based Web application code in an automatic process. As a result, the rule\-based Web application embeds a rule engine suitable for deducing information by applying an inference process. The structure of the information managed by the Web application is based on ontology classes, whereas the logical expressions applied in reasoning are obtained from production rules of the model. A rule\-based Web application has been developed and evaluated using a supporting tool that implements the ideas presented in this paper."]
