Semantic Web for E-Government

Sem-Web-EGov - Half-day tutorial at The 20th International Semantic Web Conference (ISWC 2021)

Monday, October 25th, 14:30-17:30 CET/CEST

05:30-08:30 PST

08:30-11:30 EST

20:30-23:30 CST

Public Sector Institutions have been strong advocates of Semantic Web technologies for achieving interoperability and integration among different organisational levels and provide meaningful services to citizens. On the other hand, Open data and related e-government initiatives have been motivating several research efforts in our community. This tutorial will provide attendees with a review of the cross-link between Semantic Web and this important application domain, introduce two current e-government initiatives and how they are making use of Semantic Web technologies, and provide hands-on experience on the knowledge graphs created by them, that have the potential to be valuable resources for the community.


Researchers and practitioners interested in knowing about the research opportunities provided by the E-Government use case. We also expect people interested in learning about the Linked Data resources provided by Public Sector Institution, how to use them and discuss how to imrprove them.

Participants from Public Sector organisations interested in learning about how Semantic Web technologies are used in two large scale Public Sector projects: and Ciudades Abiertas.

For hands-on sessions, we assume a basic knowledge of Semantic Web technologies (RDF, SPARQL, Linked Data stack).



Semantic Web and e-government historical account

A review of the research on Semantic Web for e-government, from publishing to querying.

14:50-15:10 A platform for integrating and assessing Europe's Linked Open Government Data

The portal (former European Data Portal) harvests the metadata of Public Sector Information available on public data portals across European countries. Information regarding the provision of data and the benefits of re-using data is also included. In this session we will introduce the manifold application of Semantic Web standards in, such as DCAT, SKOS, SHACL and DQV. A special focus will be put on the measurement and publication of quality information.


Introducing the knowledge graph (DEU-KG)

Hands-on session on querying the knowledge graph, including selecting datasets based on quality measures expressed in the DQV vocabulary.




Ciudades Abiertas: good practices for data harmonisation with local public administrations

Ciudades Abiertas ( is a collaborative project with four Spanish cities (Zaragoza, A Coruña, Madrid and Santiago de Compostela), where a suite of open resources, tools and services are being generated to support Open Government initiatives of these cities, and any other city that may want to make use of them. Particularly relevant for this tutorial is the work on Open Data, where a set of vocabularies ( are being developed to support an homogeneous provisioning of some key open datasets.


Hands-on session with selected Knowledge Graphs from Spanish cities

We will run a hands-on session where participants will be able to understand how to make use of the knowledge graphs that some of these cities are providing to reusers in different domains.


Open Government Data: beyond data and platform


Discussion session

Prof Oscar Corcho co-leads the Ontology Engineering Group (OEG) at UPM, and the Open Data Institute for the region of Madrid, in Spain. He led the Spanish thematic network on Open Data for Smart Cities, where joint guidelines and vocabularies were proposed for the harmonisation of datasets across open data portals in Spain. He has been also involved in the creation of the Spanish technical norm UNE178301:2015 on Open Data for Smart Cities, which proposes a maturity model to assess and improve the quality of open data implementations for cities, and on the ongoing initiative of the Spanish Federation of Municipalities and Provinces for the identification of the most relevant (high-value) open datasets that Spanish cities should publish in their open data portals. He has advised on the implementation of the open data API for Zaragoza, and works on the Open Cities (Ciudades Abiertas) project, with the cities of Madrid, Zaragoza, A Coruña and Santiago de Compostela.

Luis-Daniel Ibáñez is a Lecturer at the University of Southampton, UK. He has contributed to the Open Data Incubator for Europe (ODINE) H2020 innovation project, where he led the selection process of companies to enter the incubation programme, coordinating a team that evaluated more than 1000 applications over 8 rounds during a year and a half period, and granted 57 SMEs for the development of open-data centred business ideas. He was also a researcher in the European Data Portal, helping to assess the quality of metadata and RDF datasets harvested by the portal and study user logs to discover search patterns and measure usability. He has previously conducted tutorials for Quality and Scalability in Semantic Data Management (ESWC 2016) and on Data Quality for EU member state representatives as part of the European Data Portal project.

Fabian Kirstein is researcher and software developer at Fraunhofer FOKUS and a PhD candidate at the Technical University of Berlin. His work focuses on the area of Linked Open Data, Open Science, service-oriented architectures, scalable distributed systems, interactive web platforms, and dezentralised data management. In those domains he participated in several national and international research and industry projects. He contributed to the development of several Open Data platforms, such as the Open Data Portal of the city of Hamburg, GovData and OpenNRW. Since 2015 he is part of the core development team of the European Data Portal. In his Ph.D. project, he focuses on provenance, traceability and collaboration in decentralized Linked Open Data ecosystems.
