Linked Data quality assessment and improvement - from academia to industry

Thursday, September 14, 2017 - 09:00 to 17:30
The Meervaart (Room 10)

Organized by Valentine Charles and Antoine Isaac (Europeana Foundation), Amrapali Zaveri (University of Maastricht), Wouter Beek (VU University Amsterdam), Péter Király (GWDG Göttingen)



There is an unprecedented amount of data on the Web today. However, this data is only as useful as its quality allows it to be. Data Quality is an important topic in companies and organizations that use and/or disseminate large and heterogeneous Linked Datasets. These issues do not only arise in Linked Open Data, but also in Linked Business Data. At the same time, researchers are coping with Linked Data Quality issues as well, and have defined, proposed and evaluated approaches and methodologies for assessing and improving Linked Data quality.

Currently there is not one fool-proof method for dealing with Linked Data Quality issues. This workshop brings together Linked Data experts from different domains, from academia as well as industry, allowing them to share their ideas, approaches, and lessons learnt with one another.

Intended audience

Everybody who has published and/or consumed Linked Data and has run into Linked Data Quality issues.
