to Horizon Europe</span></a></em><span style="font-weight: 400;"> ». Described as a « <em>rich and structured public repository with all project information held by the European Commission such as project factsheets, participants, reports, deliverables and links to open-access publications</em> », the CORDIS catalog has also been made available in 6 European languages by Publications Office’s editorial team.</span></p> <p><span style="font-weight: 400;">Cherry on top 🍒 of a whole process, the CORDIS SPARQL endpoint release comes to crown a long-term linked open data project. The aim identifying, acquiring, preserving and providing access to knowledge in a common will to share with the widest public possible a trust-worthy, qualified and structured information (see </span><a href="https://op.europa.eu/webpub/op/annual-management-report-2021/en/"><span style="font-weight: 400;">Publications Office 2021 Annual Management Report</span></a><span style="font-weight: 400;">).</span></p> <p><span style="font-weight: 400;">In the context of the pandemic (and recent opening of <a href="https://data.europa.eu/en">data.europa.eu</a>, the official portal for European data, as defined in 2017–2025 European Open Data Space strategy), </span><a href="https://data.europa.eu/data/datasets/euroscivoc-the-european-science-vocabulary?locale=en"><span style="font-weight: 400;">the EuroSciVoc taxonomy of fields of science</span></a><span style="font-weight: 400;"> was released April 2020, followed December 2021 by the publishing of </span><a href="https://data.europa.eu/data/datasets/european-research-information-ontology?locale=en"><span style="font-weight: 400;">European research information ontology (EURIO)</span></a><span style="font-weight: 400;"> on the EU Vocabularies website 🌐.</span></p> <p><span style="font-weight: 400;">As presented at </span><a href="https://op.europa.eu/en/web/endorse-2021/conference"><span style="font-weight: 400;">ENDORSE conference March 2021</span></a><span style="font-weight: 400;">, the redesign of CORDIS data-model in accordance with Semantic Web standards contributed to bring the platform « <strong><em>from acting as a data repository to finally playing an active role as data provider</em></strong> », where EuroSciVoc taxonomy & EURIO ontology both played key roles in the creation of future CORDIS knowledge graph and SPARQL endpoint :</span></p> <p><span style="font-weight: 400;">🔸</span><em><span style="font-weight: 400;"> <a href="https://data.europa.eu/data/datasets/euroscivoc-the-european-science-vocabulary?locale=en">EuroSciVoc</a> […] is a multilingual, SKOS-XL based taxonomy that represents all the main fields of science that were discovered from the CORDIS content, e.g., project abstracts. It was built starting from the hierarchy of the OECD’s Fields of R&D classification (FoRD) as root and extended through a semi-automatic process based on NLP techniques. It contains almost 1 000 categories in 6 languages (English, French, German, Italian, Polish and Spanish) and each category is enriched with relevant keywords extracted from the textual description of CORDIS projects. It is constantly evolving and is available on EU Vocabularies website […].</span></em></p> <p><span style="font-weight: 400;">🔸</span><em><span style="font-weight: 400;"> In order to transform CORDIS data into Linked Open Data, thus aligning with Semantic Web standards, best practices and tools in industry and public organizations, the need for an ontology emerged. CORDIS created the <a href="https://data.europa.eu/data/datasets/european-research-information-ontology?locale=en">EURIO</a> (European Research Information Ontology) based on data about research projects funded by the EU’s framework programmes for research and innovation. EURIO is aligned with EU ontologies such as <a href="https://dcodings.github.io/DINGO/">DINGO</a> and <a href="https://github.com/SPAROntologies/frapo">FRAPO</a> and de facto standard ontologies such as schema.org and the Organization Ontology from W3C.
