how the
OpenAIRE
Research
Graph is
materialized

6. An open metadata research
graph of interlinked scientific
products, with access rights
information, linked to funding
information and research
communities
Graph: model for the representation of information
OpenAIRE uses it to represent objects in the scholarly communication domain and the relationships
that exist among them.
Edges of the graph are annotated with a label that specifies the semantics of the relationships
between two objects, each represented as a node in the graph.

7. The OpenAIRE Research Graph in numbers
Data sources 17K
Publications 37M

10. Enrichment
10
Different records representing the
same entity (results or organization)
are merged in one
Mining full-texts and abstracts to
identify links (e.g. to projects, to
datasets, to software), affiliations,
subject classification, citations
Enrich records with information
about relevant research communities
and infrastructures based on the
provenance of the records and their
keywords.
Propagation
Enrich records based on information
available in the records that are
linked to them with a relationship
with “strong” semantics (e.g.
supplements/isSupplementTo)

11. Integration Scenarios
● Directly harvested (from repositories, journals)
● Indirectly harvested (via aggregators, publishers)
○ see “collected from a compatible aggregator” in the Explore portal
○ records are marked to be collected from the aggregator and hosted by the
specific repository/journal (if resolvable via OpenDOAR/re3data/ISSN).
○ when the hosting source cannot be resolved, the record appears as
hosted by the “Unknown repository”

15. OpenAIRE aggregation team: UNIBI
Activities:
• Activate the aggregation workflow
• Check supplied data
• Configure transformation step to
• assign the proper typologies to records (literature, dataset, software, or
other)
• address metadata quality imperfections
• Contact repository managers
• suggest improvements
• ask for permission to download Open Access full-texts

Community Call | 04 MAR 2020

17. • OpenAIRE collects them but do not re-distribute them
• OpenAIRE explore portal will send the user to your URL
• OpenAIRE as a way to get new users/more accesses to your platform
• OpenAIRE runs mining algorithms to enrich the available metadata
• You can get back this information via the Broker
• Let other repository know that you have an Open Access version of the paper
• OpenAIRE is directly connected to the EC participant portal:
• If an Open Access version of the paper is known to exist, the life of the project
coordinator will be easier...

18. How to monitor your
aggregation
workflow?
Community Call | 04 MAR 2020

20. Collection monitor
Each box is an aggregation stage: COLLECT or
TRANSFORM

21. Collection monitor
Collection mode:
- REFRESH: OpenAIRE collected
everything
- INCREMENTAL: OpenAIRE
collected only records that have
been updated since the previous
collection

22. Collection monitor
The number of records is different: some had to be
discarded by the aggregation team.
Suggestion:
validate your repository and check the report.

23. Collection monitor
The portal
shows the
metadata
collected in this
date...
...but only these number of records get into
the pipeline
Look for the OpenAIRE logo
This version of the metadata is still
not visible in the portal

Community Call | 04 MAR 2020

25. • Infer information with full-text and data mining
• Fostering PIDs
• Propagation of ORCID IDs
• Improve discovery
• Propagation of abstracts between articles, datasets, and
software
• Improve monitoring
• Propagation of organizations from institutional data sources to
relative products and from products to linked products with
same authors
Enrichment of the graph
OpenAIRE-Advance Kick off | Athens | 17-19 Jan 2018

26. • Under implementation - Introduce relevant links
between scientific products, for example:
• Rapid view of science: identify links between articles and
relative presentations
• Hidden research software: identify link to URLs targeting rar
and zip archives
