Vinicius Medeiros Graciolli is from Porto Alegre, Brazil and is a PhD student from UFRGS (Universidade Federal do Rio Grande do Sul), where he works with a research group which specializes in artificial intelligence applied to problems in the oil industry. Most of their work consists of machine learning and conceptual modelling. He is staying at the University of Oslo for a year to work on ontology modularization: ways to slice a large ontology spanning many knowledge domains into more digestible chunks which can be presented to users more specialized into certain aspects of that ontology.
