Five reasons why 2021 has been a great year for OpenCitations

2021 is just behind us. Since January is “the Monday of the months”, as F. Scott Fitzgerald once wrote[1], it’s a good time to take stock of what happened at OpenCitations during the past year.

Among the numerous events, achievements and challenges that 2021 brought with it, we want to highlight five milestones which make us proud to look back:

1. We extended our coverage to well over one billion citations

During 2021, OpenCitations’ largest index COCI (the OpenCitations Index of Crossref open DOI-to-DOI citations) was able to include for the first time the citation links involving references that had been opened at Crossref by Elsevier and the American Chemical Society, thereby greatly expanding its coverage. The last release of COCI (November 2021) is based on open references to works with DOIs within the Crossref dump dated October 2021, and, as a result, COCI now contains information on more than 1.23 billion citations involving almost 70 million publications.
A recent analysis by Alberto Martìn-Martìn (Facultad de Comunicación y Documentación, Universidad de Granada, Spain), published on the OpenCitations Blog in October, shows that the citation coverage provided by OpenCitations is approaching parity with that of the leading commercial citation indexes, Web of Science and Scopus, offering a viable alternative upon which to base open and reproducible metrics of academic performance.

2. OpenCitations team grew

Last summer, we appointed Claudio Fabbri as our Administrator and Research Manager to take responsibility for the day-to-day administrative and financial activities of OpenCitations; Chiara Di Giambattista as Communications Director and Community Development Manager to take care of all communications and community interactions made on behalf of OpenCitations; and Giuseppe Grieco as our new Software and Systems Developer to take charge of technical development related to the OpenCitations services.

Thanks to the support from the OpenAIRE Nexus project, the team has also recently welcomed Arcangelo Massari as our new Software Developer to take care of the development of the new database OpenCitations Meta. We anticipate further appointments during 2022!

Our International Advisory Board met in November, and we thank its members for the valuable advice they provided. The Board will meet again later this month.

3. We participated in many international meetings

During the past year, OpenCitations’ directors Silvio Peroni and David Shotton took part in numerous international conferences, webinars and workshops, including the LIBER Annual Conference 2021, the OS Fair 2021, OASPA 2021 and FORCE2021. These provided excellent opportunities to describe and promote OpenCitations, to reach out to new potential stakeholders, and to discuss with other experts the main themes of our activities and plans as they relate to Open Science.

The year ended with a bang, with the announcement during the closing session of FORCE2021 that the 2021 Open Publishing Award for Open Data had been awarded to OpenCitations.

4. We received a world of support

In 2021, thanks to our involvement in the SCOSS funding campaign and to our commitment to reaching out to the libraries and universities potentially interested in OpenCitations, we gathered a wide international community of stakeholders and supporters around us. We are deeply thankful to the 6 consortia and 56 institutions across the globe which are now supporting us financially, thus making it possible for us to enhance our services and expand our team. You can find the full list of our supporters on the OpenCitations website and in this recent Thank You video:

Additionally, in January 2021, we started our involvement in the EC-funded OpenAIRE Nexus project, bringing us into closer collaboration with our European colleagues and infrastructures, including OpenAIRE. The main aim of the project is to create a framework of services for assisting in publishing research, monitoring its impact, helping promote its discovery, and integrating it into the European Open Science Cloud (EOSC) “for the benefit of the open science community worldwide”. In OpenCitations, we’re thrilled to be part of this collaborative project by providing open bibliographic citations as part of the open data components of OpenAIRE and the EOSC.

5. We set the stage for future developments

Thanks to the research grants and the support and endorsement we have received from the international scholarly community, we are now working on a variety of new services, thus setting our goals for the coming years. In particular, we want to enhance OpenCitations partnerships and dialogue with the scholarly community; to collaborate with colleagues to develop new services that will expand our citation coverage, including new OpenCitations indexes of NIH-OCC, of DataCite and of other sources of open references, that will all be searchable through a single API; and to create OpenCitations Meta, our new database that will hold comprehensive bibliographic metadata of the publications involved in our indexes citations, thereby enabling faster query responses and the ability to host citations involving publications lacking DOIs[2].

OpenCitations receives the Open Publishing Award in Open Data

What role does ‘open’ play in making this project special?”

This apparently easy, but not banal, question was asked in the Open Publishing Awards nomination form, and at OpenCitations we prefaced our answer to it by stating “For OpenCitations, ‘open’ is the crucial value and the final purpose.” We consider the free availability of bibliographic citation data to be a necessary condition for the establishment of an open knowledge graph, and believe that having citations open helps achieve a more transparent, accessible and comprehensive research practice.

Since 2019, the Open Publishing Awards, founded and organized by the Coko Foundation and sponsored by OASPA, Crossref and Cloud68.Co, “celebrate software and content in publishing that use open licenses but also, importantly, provide a chance to reflect on the strategic value of openness”. The award judges considered open access projects divided into five categories: Open Publishing Lifetime Contribution, Open Content, Open Publishing Models, Open Source Software and Open Data.

It is in this final Open Data category of the Open Publishing Awardsthat OpenCitations was selected, as an infrastructure that perfectly represents the open principles, from among the few semantic web and linked open data initiatives currently available in the scholarly communication landscape. The award was announced in the Open Publishing Awards Ceremony, during the closing session of the FORCE2021 conference “Joining Forces to Advance the Future of Research Communication” (7-9 December). You can learn more about the Awards and the other projects selected here: https://openpublishingawards.org/results/2021/index.html

The greatest honour for OpenCitations was receiving the following comment given on behalf of the jury panel, which included open source and scholarly communication experts:

“At the time of writing this review, the largest database provided by OpenCitations contains more than 1.23 billion citations. Compiling this database in a license-friendly way is a feat on its own, but combine that with OpenCitations’ persistence (established 11 years ago), their active and consistent involvement with the community, and the number of works that were made possible by their effort (Google Scholar lists 1440 results), it is clear that OpenCitations is one of the fundamental projects in open publishing, specifically in open scientific publishing”.

We are proud and humbled to count the Open Publishing Award in Open Data among the acknowledgements so far received by OpenCitations. Despite the term “award”, the Open Publishing Awards, in fact, don’t aim to proclaim winners, but rather to “shake the hands” of some projects which seem to be following (and tracing) a right path towards a more open knowledge. All the projects awarded help by defining more concretely what “open”means, and at the same time their example encourages awareness on the variety of the open publishing projects, and a reflection about the common values and goals that gather so many different people, institutions and organizations.

Recognizing the commitment to the openness of knowledge and research of the not-for-profit and collaborative projects like OpenCitations is about community, not competition.

As Silvio recently stated:

OpenCitations is a plural. Together, we are OpenCitations.”

2011 retrospective: meetings on the future of research communications

What a year it has been!  Four key meetings were held during 2011, bringing together academics, computer scientists and scholarly publishers to discuss the future of scholarly communication.  The first of these, a workshop entitled Beyond the PDF, organized and hosted in January 2011 by Philip Bourne at the University of California, San Diego, itself built on an earlier HyPER workshop organized in May 2010 in Amsterdam by Anita de Waard of Elsevier Labs (de Waard et al. 2009, [1]).  It was followed by a meeting entitled Beyond Impact, organized by Cameron Neylon of STFC at the Wellcome Trust headquarters in London in May 2011, that considered alternative metrics to the journal impact factor for the evaluation of research – and particularly researcher – merit.  In August 2011, a further meeting on The Future of Research Communication, organized by Phil Bourne of UCSD, Tim Clark of Harvard University, Robert Dale of Macquarie University, Anita de Waard of Elsevier Labs, Ivan Herman of the W3C, Eduard Hovy of the University of Southern California and myself, was held in Germany as a Schloss Dagstuhl Perspectives Workshop.  This led to the formation of the Force11 Community dedicated to the improvement of research communication and e-scholarship, and to the publication in October 2011 of the Force11 White Paper (Bourne et al., 2011), that was submitted as evidence both to the Royal Society’s Science as a Public Enterprise project and to the UK Cabinet Office’s public consultation Making Open Data Real.  Finally, in October 2011, Microsoft Research and Harvard University jointly hosted a meeting in Cambridge, Massachusetts, entitled Transforming Scholarly Communication, that took these ideas forward.

Additionally, the benefits of Semantic Web technologies for libraries were recently discussed at the 2011 annual Semantic Web in Libraries meeting entitled Scholarly Communication in the Web of Data, held in Hamburg, Germany, in November 2011.

The thinking undertaken at these meetings contributed significantly to the formulation of my paper entitled The Five Stars of Online Journal Articles described in a previous post, and significantly advanced the community’s thinking as a whole both on semantic publishing of journal articles and on the issues surrounding research data publication.

I’m looking forward to what 2012 brings!
