The Initiative for Open Citations (I4OC.org)

Aim of I40C
To promote the availability of data on citations that are structured,
separable, and open.
Structured - the data representing each publication and each citation instance
are expressed in common, machine-readable formats.
Separable - citations can be accessed and analyzed without the need to access
the source bibliographic products (such as journal articles and books).
Open - the data are freely accessible and reusable.

Why?
Establish a global public web of linked scholarly citation data to enhance
the discoverability of published content, both subscription access and open
access.
This will particularly benefit individuals who are not members of academic institutions
with subscriptions to commercial citation databases.
Build new services for the benefit of publishers, researchers, funding
agencies, academic institutions and the general public
And enhance existing services.
Create a public citation graph to explore connections between knowledge
fields, and to follow the evolution of ideas and scholarly disciplines.

How it came
together
The starting point
Most publishers already deposit
their citation data with Crossref
The default state for the data is not
open
The challenge
Could we persuade a group of
influential publishers to release
their data all at once?

Making the case
It’s easy and doesn’t cost anything
All you need to do is to send an email to support@crossref.org
Publishers also benefit
Better discovery tools mean that content will be found and
used more
The goal cannot be achieved alone
A comprehensive network of all scholarship can only be
achieved if data is pooled

Making it happen
Agree a deadline
Everyone has time to prepare their comms and to be part of a
big splash
Focus on publishers depositing the most data
Contacted the top-20 publishers asking for agreement in
principle and permission to share their decision
Leverage the early adopters
As soon as we had a few publishers on board, others quickly
followed

Why are publishers joining I4OC?
“If you’re not looking to
monetize references in some
way, why wouldn’t you?”
“We believe there is great benefit
in supporting sustainable and
standardized infrastructure.
Opening up our reference
metadata cost us no more than
the time required to write one
simple email.” Liz Ferguson,
Wiley
“At Taylor & Francis we are
working to make it as easy as
possible for the communities we
serve to achieve their open aims.
I4OC sits well with this, and was a
very quick and easy process to
implement.”
“Although we charge for metadata
feeds, those are service- rather
than content-based charges. We
didn’t identify any commercial
downside of supporting I4OC as
we are highly unlikely to develop
significant revenue streams from
just our own references.”

“References have long been a path to
serendipitous discovery. Making citation
data open and machine readable will
only accelerate that discovery
process for researchers.”
Why are publishers joining I4OC?
“One of the key purposes of a
publisher is to assist in the
development of networks of
scholarship to aid the cross
fertilization of research. Freeing
up the reference data is an
extremely powerful way of doing
that.”
“One of the most exciting
benefits is the potential to
expose networks of research
that might otherwise take
years to discover.”
“It will make our customers’ lives
easier by helping data scientists to
mine a large body of references in
one go. Currently we see little threat
to our business as this aligns perfectly
with our aims to go beyond open
access to research, by using open
approaches and utilizing our own data
to advance discovery.” Steven
Inchcoombe, Springer Nature

The Initiative for Open
Citations
We built a coalition of major funders,
technology platforms, open data
organizations and publishers supporting
the unrestricted availability of scholarly
citation data.

One year on…
The fraction of open citation data has surpassed 50%
The number of participating publishers has risen to 490.
There are over 500 million references now openly available.
There are almost 50 stakeholder organisations who have joined
I4OC to help advocate and promote reuse of open citations.
The initiative has attracted commentary and media coverage
across the world.

Of the top-20 biggest
publishers with citation
data, all but five now
make these data open via
Crossref.
Three represent Scholarly
Societies…

Crossref was founded to enable a
shared reciprocal linking and
metadata exchange, removing the
need for bilateral agreements
between publishers and other
service providers.

Why do we need open citations?
The ability to undertake large-scale and generalizable
bibliometric research … is limited to a few well-funded centers
that can afford to pay for full access to the raw data of Web of
Science or Scopus.
…scientometricians need a data source that is freely available
and comprehensive. This is a matter of scientific integrity,
scientific progress, and equity
Scientometrics is widely used to support science policy and
research evaluation, with consequences for the entire scientific
community. There is a need for specialized organizations, both
commercial and non-commercial, that offer scientometric
services.
...to guarantee full transparency and reproducibility of
scientometric analyses, these analyses need to be based on open
data sources.
advocating for open references is critical to ensure replicable and
equitable research practices.
We should use our relationships with journals—as authors,
reviewers, and editorial board members—to advocate for
openness and should expect scientometric journals to be leaders
in this respect.
“References are a product of scholarly work and represent the
backbone of science—demonstrating the origin and advancement
of knowledge—and provide essential information for studying
science and making decisions about the future of research.
References are generated by the academic community and should
be freely available to this community.”

Fig 1. Citation distributions of 11 different science journals.
Citations are to ‘citable documents’ as classified by Thomson
Reuters, which include standard research articles and reviews. The
distributions contain citations accumulated in 2015 to citable
documents published in 2013 and 2014 in order to be comparable
to the 2015 JIFs published by Thomson Reuters. To facilitate direct
comparison, distributions are plotted with the same range of
citations (0-100) in each plot; articles with more than 100 citations
are shown as a single bar at the right of each plot.

Can Scientists Assess Merit or Predict
Impact?
Analysed subjective rankings of papers from two different data
sets over five years
• Faculty of 1000
• Welcome Trust (data from Allen et al. of 2 assessor
rankings within 6 months of publication)
• In relation to citations and impact factor
Eyre-Walker A, Stoletzki N (2013) The Assessment of Science:
The Relative Merits of Post-Publication Review, the Impact
Factor, and the Number of Citations. PLoS Biol 11(10):
e1001675. doi:10.1371/journal.pbio.1001675
http://www.plosbiology.org/article/info:doi/10.1371/journal.pb
io.1001675

Subjective assessments of science are poor:
Very weak correlation between assessors
Strongly biased by the journal in which the paper was published
Number of citations or the impact factor exaggerates differences between papers
Scientists are also poor at predicting the future impact:
Because they are not good at assessing merit
Similar articles accumulate citations essentially by chance.
“What this paper shows is that whatever merit might be, scientists can't be
doing a good job of evaluating it when they rank the importance or quality of
papers. From the (lack of) correlation among assessor scores, most of the
variation in ranking has to be due to ‘error’ rather than actual quality
differences.”

Institutional (rankings…)
National and International
Cannot be distilled into a single number or proxy

What is Open Science? It is endeavoring to preserve the rights of others to
reach independent conclusions about your data and work.
8:47 PM - 5 Dec 2017
Why

most of the data needed to support Open Science is
controlled by commercial companies, both big and
small. This growing reliance on a handful of companies
to provide proprietary analytics and decision tools for
research funders and universities poses serious risks for
the future
Open Source
• prevents monopolistic control
• requires an active community of users and service
providers to develop and maintain infrastructure
Open Data
• metadata about the research process itself, such as
funding data, publication and citation data, and
“altmetrics” data
Open Integrations
• standard metadata formats and open APIs
Open Contracts
• completely open (public) and no lock-in (e.g. Non-
Disclosure Agreements, multi-year contract terms, and
privately negotiated prices)

I am a scholarly publisher already depositing
references to Crossref. How do I publicly release
them?
If you are already submitting article metadata to Crossref as a
participant in their Cited-by service:
1. Contact Crossref support directly by e-mail, asking them to turn on
reference distribution for all of the relevant DOI prefixes
OR
2. Set the <reference_distribution_opt> metadata element to "any" for
each DOI deposit for which they want to make references openly
available.

How you can help (1)
• Publishers who aren't making their references public yet - send an email to
Crossref before the end of the month requesting them to make your references
open. It's that simple!
• Publishers who don't yet deposit references with Crossref - contact Crossref to
find out how to do this.
• Editors and editorial board members – if references in your journal are not yet
made public - contact your publisher and request this. Use this list to see whether
your publisher is already making references open.
• Funders, institutions, companies, researchers, and all other users of open
citation data - write a short piece about your work and the benefits of open
citation data for the I4OC website. Please contact info@i4oc.org.

How you can help (2)
• If you have a story about open citation data and why they matter to
your organization and community, share a link, tag it as
#OpenCitationsMonth. We’ll retweet it to our followers.
• Please keep an eye on the #OpenCitationsMonth tag, and help us to
amplify the message.
