Lecturer and Researcher

F1.81

Short bio

I’m a researcher at the University of Seville. My research so far has focused on techniques related to structured data integration and mining, lately in the field of knowledge graphs. This includes, for example, labelling elements in structured information with a class, finding equivalence between properties, or testing graph embedding techniques.
