Mémoire présenté en vu d'obtenir l' Habilitation à Diriger des Recherches, spécialité " Informatique " par Nathalie Pernelle. Over the last fifteen years, I have focused on issues related to the general problem of enriching unstructured documents or structured RDF data with semantic information. This has been done following three main researchaxes. A first research axis has been dedicated to the definition of approaches that automatically construct class hierarchies over XML data when there is no domain ontology available. Since this work is rather old now, I will only describe it briefly in this chapter but I will not detail it in this thesis. In a second research axis, I have investigated different approaches that can be used to annotate unstructured data using available ontologies. A third research axis has been devoted to the enrichment of RDF datasets with identity links when RDF datasets conform to OWL ontologies.
