Strengthen the quality of linkages and authority data

IdRef contribute to the quality of authority data

Forms are available from each record IdRef to allow Internet users to report any erroneous information, broken or missing links (...) or to propose bibliographical enrichment. 

In the logic of crowdsourcing, everyone can thus contribute to the quality of the ESR's authority data.

Please note: proposed changes are not processed byAbes. They are sent to the libraries that originally catalogued the authority records concerned and processed by them

Rights relating to personal data

Within the framework of its national mission of reporting ESR documentary resources, the ESRAbes has authority files that may contain personal data (e.g. date of birth, form of name, country). These files have been filed with the CNIL, which authorized them.

In accordance with the RGPD, the exercise of the rights of information, access, rectification and opposition to personal data is guaranteed. If a user wishes that certain personal data concerning him or her is no longer available, a Request for Rectification of Data form is available on each IdRef notice so that each user can exercise his or her right to rectification.

Please note: requests for data correction are not processed byAbes. They are forwarded to the libraries that originally catalogued the authority records concerned and are processed by them strengthening the quality of links between records

In service since 2019, is a professional interface dedicated to the quality of links between authority records IdRef "natural persons" and access points present in bibliographic records Sudoc.

Developed byAbes, according to the UX Design methodology (regular user tests and iterative processes), this application - user-friendly, even playful - is available to the network's catalogers Sudoc.

Logo Paprika Go to Paprika offers a working environment adapted to the task of identifying authority records (or "natural person" entities) with close or identical names in the event of a homonym, which leads to potential matching errors between records.

By using paprika.idref.frthe following features are available to library professionals:

  • adding or modifying links between records
  • bounce to the cataloguing module ofIdRef to create the missing authority records.
  • possibility of relying on the Qualinka artificial intelligence service which exploits all the wealth of data and links between these data (authority and bibliographic). As a decision support service, Qualinka diagnoses potential errors and suggests actions to the cataloguer.

A fruitful partnership between LIRMMAbes and LIRMM - GraphIK team

The application was developed byAbes by adapting an artificial intelligence service, developed in collaboration with the GraphIK team at LIRMM.

The heart of this service is an original and generic engine developed by the GraphIK team.

It is a linking engine between bibliographic Sudoc references and authority data. It can be parameterized (ontologies, attributes, filters, criteria, linking rules and differences, etc.) according to the problems specific to the type of linking between records.

The results provided are used by a diagnostic service (Brett report) providing quality control information on the links of Sudoc as well as suggestions for modification.

AlgoDoubles and AlgoLinks: detecting anomalies

Based on web services technology,Abes provides network members (Cataloguing Correspondent, Authorities Correspondent, Coordinator Sudoc ...) with two quality control tools synchronised in real time on the production environments Sudoc and IdRef.

These web services are called from a URL, to which different parameters can be added, for example to restrict the search to a particular batch (ILN, RCR, date ...). Once the data analysis process is completed, a report of anomalies is generated (.txt file downloadable). 


AlgoDoublons is a detector of potential duplicate authorities.

Based on a clustering process carried out by VIAF, AlgoDoublons makes it possible to identify whether several records fromIdRef are grouped together in the same VIAF "cluster": they may be genuine duplicates or records with incorrect bibliographic links.


AlgoLinks is a detector of missing links identified in the link fields of bibliographic records Sudoc.

Anomaly reports: support for curing yards

Anomaly reports are particularly useful in the context of data quality and curation projects. For cataloguers, they are real monitoring files that guide them through the various stages of a "data quality" work plan. The necessary corrections are made from the appropriate applications (WinIBW, IdRef, Paprika)
