Designing Virtual Knowledge Graphs with Ontop and Ontopic Studio
Diego Calvanese, Benjamin Cogrel, and Davide Lanti
In this tutorial, Diego Calvanese, Benjamin Cogrel, and Davide Lanti will teach participants how to design of virtual knowledge graphs (VKGs) using Ontop and Ontopic Studio*. This tutorial will cover:
- Introduction to Virtual Knowledge Graphs (VKGs), OWL2QL, mappings and IRI templates, mapping saturation, and query formulation with Diego Calvanese
- Introduction to Ontopic Studio with Benjamin Cogrel
- Virtual Knowledge Graph (VKG) design via Ontopic Studio (hands-on) with Benjamin Cogrel
- Setting up and accessing a SPARQL endpoint using Ontop (hands-on) with Davide Lanti
Bio: Diego Calvanese is a full professor at the Research Centre for Knowledge and Data (KRDB) of the Faculty of Computer Science, Free University of Bozen-Bolzano (Italy), where he leads the Intelligent Integration and Access to Data (In2Data) research group. He is also Wallenberg Guest Professor in Artificial Intelligence for Data Management at Umeå University (Sweden). His research interests concern foundational and applied aspects in Artificial Intelligence and Databases, notably formalisms for knowledge representation and reasoning, Virtual Knowledge Graphs for data management and integration, Description Logics, Semantic Web, and modeling and verification of data-aware processes. He is the author of more than 400 refereed publications, including ones in the most prestigious venues in Artificial Intelligence and Databases, with more than 35000 citations and an h-index of 74, according to Google Scholar. He is a Fellow of the European Association for Artificial Intelligence (EurAI), of the Asia-Pacific Artificial Intelligence Association (AAIA), and of the Association for Computing Machinery (ACM). He is the originator and a co-founder of Ontopic, the first spin-off of the Free University of Bozen-Bolzano, founded in 2019, and developing AI-based solutions and technologies for data management and integration.
Bio: Davide Lanti is an Assistant Professor at the Research Centre for Knowledge and Data (KRDB) of the Faculty of Computer Science, Free University of Bozen-Bolzano (Italy), where he carries out research on Virtual Knowledge Graphs, Semantic Web, Databases, and Description Logics. He received his MSc degree in Computational Logic jointly from the Technische Universität Dresden (Germany), and the Free University of Bozen-Bolzano (Italy). He received his PhD at the Faculty of Computer Science at the Free University of Bozen-Bolzano, Italy.
Bio: Benjamin Cogrel is CTO and co-founder of Ontopic, a spin-off from the Free University of Bozen-Bolzano specialized on Virtual Knowledge Graphs and Knowledge Graph Construction. He is also one of the main developers of Ontop, the most popular open-source Virtual Knowledge Graph engine. Prior to founding Ontopic, Benjamin was a Post-Doc from 2014 to 2019 in the Intelligent Integration and Access to Data (In2Data) research group at the KRDB research centre at the Free University of Bozen-Bolzano, where he worked on Virtual Knowledge Graphs and brought important contributions to Ontop. He received his PhD in Computer Science at the University of Paris-Est in 2013.
FAIR principles and semantic artifacts, what to do?
“Os princípios FAIR e os artefatos semânticos, o que fazer?”
Luiz Olavo Bonino
In this tutorial, Luiz Bonino will address the intersection between FAIR’s principles (Findable, Accessible, Interoperable, Reusable) and the ontology engineering process, helping the participant to understand how to turn their ontology into a FAIR artifact. Throughout the tutorial, the following points will be explored:
- FAIR principles – Findable, Accessible, Interoperable, Reusable.
- Implications of FAIR principles for ontologies
- How to evaluate the FAIRness of an ontology
- How to make an ontology more FAIR
Bio: Luiz Olavo Bonino is Associate Professor in the Services and Cybersecurity group at the University of Twente and in the BioSemantics group at the Leiden University Medical Centre. His background is in ontology-driven conceptual modelling, semantic interoperability, service-oriented computing, requirements engineering and context-aware computing. Since 2014 Luiz has focused on research, design and development activities related to supporting the making, publishing, indexing, searching, evaluating and annotating FAIR (meta)data and services.
