Research project: "Semantics on top of data (Ontop)"

 Previous element Next element 


The overall goal of this project is to extend and enrich techniques and tools for intelligent access to information to cope with the size and complexity of big data, and with novel types of data and rich ontology languages.


  1. To optimize query processing techniques in ontology-based data access
  2. To develop techniques for dealing with temporal data and non-relational data (noSQL)


  • Ontology-based data access and integration
  • Knowledge representation and reasoning

Key technologies

  • OWL
  • RDF
  • OBDA technology


  • Big Data
  • Data integration


Diego Calvanese ( ,   web site)

Diego Calvanese is a full professor at the Faculty of Computer Science of the Free University of Bozen-Bolzano. He teaches graduate and undergraduate courses on knowledge bases and databases, ontologies, theory of computing, and formal languages. He received a PhD from Sapienza University of Rome in 1996. His research interests include formalisms for knowledge representation and reasoning, ontology-based data access and integration, description logics, Semantic Web, graph data management, data-aware process verification, and service modeling and synthesis. He has been actively involved in several national and international research projects in the above areas (including FP6-7603 TONES, FP7-257593 ACSI, FP7-318338 Optique). He is the author of more than 300 refereed publications, including ones in the most prestigious international journals and conferences in Databases and Artificial Intelligence, with almost 25000 citations and an h-index of 65, according to Google Scholar. He is one of the editors of the Description Logic Handbook. He has been nominated Fellow of the European Association for Artificial Intelligence (EurAI, formerly ECCAI) in 2015.
