Most literature in conceptual modelling focuses on the development of models. However, models, once created, must be used, which requires that the model is as usable as possible. Often, usage scenarios for a model are only vaguely clear at model creation time, so model usability should be considered as a relevant problem, especially in relation to conformance (creating instance models that conform...
The goal of this work is to design and develop an Information System that integrates human genome variation data currently scattered in different repositories. The continuous and increasing interest generated around the variations knowledge, makes the study of this research topic from an Information System point of view extremely attractive. The system has been developed following a conceptual-model...
Semantic Web applications often rely on the reuse of underlying data from legacy information systems. The motivation for our research is how to make this data accessible for use in such applications. We propose the use of ontologies and conceptual modelling in an overall approach for data interoperability. The approach incorporates a process for ontology alignment using our tool for visual ontology...
