In this paper, we present an ontology-based approach to compose applications
while preserving their former look. Our composition process relies on the
manipulation of User Interfaces (UI) and on several ontologies describing
relationships between tasks, UI and Functionalities. Our tool, called
OntoCompo, supports compositions realized by the developer thanks to the
selection, extraction and positioning of UI elements to constitute the
newapplication.Comment: d\'emonstration \`a la conf\'erence IHM 201
