The EC FP7 Post-Grant Open Access Pilot: An Attempt to Implement Fair Gold Open Access

Guest post by Pablo de Castro, Open Access Project Officer, LIBER

A new Gold OA funding initiative has been launched earlier this year by the European Commission: the FP7 Post-Grant Open Access Pilot. This initiative, which is being implemented under the OpenAIRE2020 project, will use its EUR 4m budget to fund OA publishing fees for publications arising from over 8,000 completed FP7 projects covering the whole European Union and neighbouring countries – a large subset of which feature British institutions among its partners.

This post-grant Pilot aims to test the need for additional funding once the FP7 projects finish and their grants are over. Publications will very often arise after the project end-date, so this is an instrument for supporting the Open Access publishing of research articles and monographs for which the projects and their researchers may no longer have any available budget.

The biggest challenges the project team have identified thus far lie in the sheer geographic coverage of the initiative and in the radically different approaches towards Gold Open Access that co-exist across Europe. The scale issues will be addressed by relying on the comprehensive network of professionals, institutions and their best practices in Open Access implementation and dissemination that OpenAIRE provides. The
Pilot partner network – which includes the Jisc in the UK, SURF in The Netherlands, the University of Göttingen in Germany and the University of Athens in Greece under the coordination of LIBER in The Hague – will also contribute to meet the need to reach out to eligible researchers and projects across the whole Continent.

The second big challenge involves the need for this Pilot to operate under the three main different scenarios for Gold OA implementation identified by the network of institutions taking part in the project kick-off stage, as described in the slide below which was presented and discussed last June at the Gold Open Access Pilot workshop at the LIBER Annual Conference in London.

Gold OA funding landscape

In order to deal with this fragmented funding landscape, the Pilot will try to promote a specific brand of fair Gold OA that aligns with the highest possible number of funders’ policies across the Continent. There is a well-acknowledged divide in the way Gold OA is being presently implemented in Europe: while UK funders like RCUK or the Wellcome Trust/COAF will fund APCs in both fully Open Access and hybrid journals applying no funding cap to their eligibility criteria, European funders like the German DFG, the Norwegian Research Council, the Austrian FWF and the Dutch NWO will all either rule out or restrict funding for hybrid journals and often establish funding caps.

The eligibility criteria for this FP7 Post-Grant OA Pilot will then exclude funding for hybrid journals and set a €2,000 funding cap for research articles and a €6,000 one for monographs and edited volumes. Besides this, the policy requires a CC-BY licence, a text-minable file version besides the standard PDF one and their deposit into an OpenAIRE-compliant repository. This policy for funding APCs is then coupled to an alternative APC-equivalent funding mechanism which aims to also fund APC-free OA journals as a means to address the wider scope of Gold Open Access, which does not just involve the APC-based business model.

Thorough discussions held on such policy both within the project partner group and with an extensive selection of external reviewers highlighted the severe risk of underspending that ruling out funding for hybrid titles would pose, and in fact the results of the first two months of Pilot operation show this as a looming threat on the initiative. However, the project has only just started and the summertime season means there’s less activity: data on the next report due end-of-Sep will surely look more encouraging. But there is a clear need anyway for institutions to support the dissemination of the initiative towards their eligible researchers and projects and to help them navigate the potentially obscure policy requirements (despite the strong recommendation included in the policy guidelines that authors should check with their institutional Library or Research Office before submitting a funding request, plenty of funding applications are arriving for articles accepted at hybrid journals, which are systematically turned down much to the author’s occasional dismay). The Pilot coordination – which may be reached here (email) – is keen to support the outreach work at institutions by delivering eligible FP7 project lists where useful or by providing any additional assistance – a support service that the Jisc will also be able to provide as OpenAIRE National Access Desk (NOAD) for the UK.

Should this initiative manage to safely clear the perilous strait between the Scyllean Green Open Access that OpenAIRE is understandably very keen on and the Charybdian threat of the often ill-informed dismissal of any kind of Gold OA as commercial publisher-friendly and prone to double-dipping, this would be very good news for the Open Access community. The success of this initiative would mean a way to implement a reasonably well-aligned policy that will eventually drive down APC costs by promoting a cultural change in the publishing habits. The opportunity UKCoRR have kindly offered to further disseminate this funding initiative to institutions where the mechanisms are often already in place to provide researchers the support they require is greatly appreciated.

Results of the Sherpa FACT accuracy testing – 95% accurate

UKCoRR welcomes the results of a  recent exercise – undertaken by UK librarians, repository managers and Sherpa Services – that has shown that the results produced by SHERPA/FACT (Funders & Authors Compliance Tool) have an accuracy rate of over 95%

The FACT service was developed to help researchers get a simple answer to the question “does this journal have an open access publishing policy compliant with my funder’s open access mandate?”. The FACT service – which draws its information from the SHERPA/ROMEO and SHERPA/JULIET databases – seeks to provide a yes/no answer to this question, as well as providing information about how an author can comply with a funder policy.

There had been some discussion at the SHERPA/FACT Advisory Board, raised by UKCoRR members and their institutions – as to whether the information provided by FACT was accurate.

To address this issue an exercise was undertaken – by members of UKCoRR – to manually check a statistically significant number of journal/funder combinations and then compare the information this group had found with the information provided by FACT. Where the independent reviewers arrived at a different conclusion to that provided by FACT, then that journal/publisher combination was subjected to detailed and exhaustive investigation to arrive at an evidenced answer.

At the end of this exercise, it was found that the FACT service provides correct information in over 95% of cases.

The study clearly highlighted the difficulties that even highly experienced repository staff have at deciphering publisher OA policies. Indeed, the initial testing undertaken by UKCoRR members suggested that FACT was only accurate on 57% of occasions. When these journal/funder combinations were investigated further, however, close examination of the often complex conditions and the interactions between different statements and policies showed that FACT was correct in almost all of the cases.

The SHERPA/FACT team as well as the SHERPA/FACT Advisory Group would like to extend their thanks to the UKCoRR Members who took part in this checking process for their time commitment as well as their extensive knowledge of this area of work. This exercise has proved that the SHERPA/FACT service can be relied upon as a source of advice for UK researchers. UKCoRR also encourages it’s members to continue to communicate with SHERPA/FACT where discrepancies are found to continue to improve the quality of the information SHERPA/FACT relies upon.

Issues of interpretation and the interaction between the various policies have been seen to be the key to the discrepancy between our manually checked results and Sherpa’s findings. There is further work to be done here and UKCoRR looks forward to continuing to work with the SHERPA/FACT Advisory Group to develop increased clarity in this area.

The study was commissioned by the SHERPA/FACT Advisory Board – which includes representatives from UKCoRR, Jisc, Wellcome Trust, Research Councils UK (RCUK), CRC Nottingham, Association of Learned & Professional Society Publishers (ALPSP), Higher Education Funding Council for England (HEFCE), Publishers Association and SCONUL.

Ranking altmetrics: DIY

In the previous post Network effects: on alternative metrics I presented the top 10 articles by altmetric for repository downloads in April 2015 as recorded by IRUS-UK. This is a quick post on how to do it for any set of DOIs.

IRUS-UK provides a rich data set currently comprising 84 UK repositories with a total of more than 36 million unique item downloads recorded, and if you are an IRUS participant you can easily derive data for your own repository.

Log-in to the portal at http://www.irus.mimas.ac.uk/ via UK Access Management Federation and navigate to Statistics Reports, Article Report 4, limit the date range you are interested in, select your repository – I’m actually using White Rose Research Online here as a consortium of 3 major research institutions (Leeds, Sheffield, York)- and output as CSV:

Use MS Excel to filter blanks and other gubbins from the DOI column and cut and paste the resulting list into a Google sheet.

Now you need the script below, kindly provided by the founder of altmetric.com Euan Adie, Tools -> Script editor -> Blank project, just cut and paste and save the project:

function ALTMETRIC_SCORE(input) {
var response = UrlFetchApp.fetch(“http://api.altmetric.com/v1/doi/” + input, {muteHttpExceptions: true});
var data = response.getContentText(“UTF-8″);
if (data.length <= 10) {return 0;}
var json = JSON.parse(data);
Utilities.sleep(1000);
return Math.floor(json.score);
}

GoogleScript

Now return to your Google Sheet and simply type the formula into the first cell of column B referencing the equivalent cell in column A:

1. Type the formula into the first cell as =ALTMETRIC_SOURCE(A2)
1. Type the formula into the first cell as =ALTMETRIC_SCORE(A2)

Now you just need to drag the formula into every cell in column B – using the handle in the bottom right corner – to run against the corresponding cell with a DOI in column A.

HOWEVER, unfortunately you can’t just do thousands or even hundreds at a time as it will upset Google’s rate limiter and you will get increasing numbers of cells screaming ERROR! so you need to do them in batches of about 100 at a time:

Drag formula into all cells in column B
2. Drag formula into all cells in column B
3. Script will run for each cell in column A
3. Script will run for each cell in column A
4. Don't drag to the next batch of cells until data is loaded
4. Don’t drag to the next batch of cells until data is loaded

Once this is done, which can be painstaking with several thousand records, you can use Sort sheet Z-A to rank highest to lowest.

WARNING – if you do this with the column containing the live formula it will run again for all cells at once and throw hundreds of errors which is what the painstaking process was meant to avoid…so copy and paste values only into the next column and sort on that! It is likely that there will be some ERRORS and you can run the formula again in another column though some of them may just be dud DOIs.

And there they are, all records downloaded from WRRO (with DOIs*) since that repository joined IRUS in October 2013 ranked highest to lowest by altmetric *some of the records excluded by the initial filter on DOI may in fact have a DOI of course that isn’t available from IRUS (or presumably the originating repository) so to be really thorough you might try to track them down!

Network effects: on alternative metrics

“No one can read everything. We rely on filters to make sense of the scholarly literature, but the narrow, traditional filters are being swamped. However, the growth of new, online scholarly tools allows us to make new filters; these altmetrics reflect the broad, rapid impact of scholarship in this burgeoning ecosystem. We call for more tools and research based on altmetrics.”

altmetrics: a manifesto

Research metrics are nothing if not controversial, none more so than the “alternative” variety currently in vogue from Plum Analytics, ImpactStory and the donut people themselves altmetric.com. For the most part, the twitterati are buying into them in a big way, not to mention Big Publishers and Open Access advocates, though some influential voices are dismissive. At best. See this title from David Colquhoun and Andrew Plested “Why you should ignore altmetrics and other bibliometric nightmares“. Or even read it – it’s hard to deny that most folk who retweet the monster-altmetric articles probably don’t (personally I eschew the RT without having read an article, whether academic or pop-cultural trivia. Maybe that’s just me*)

* I’ll admit occasionally to having retweeted *before* reading but only if I trust the source.

Though a mere bibliometric tinkerer myself, I rather take umbrage on behalf of professional bibliometricians everywhere who are somewhat maligned in this article: “The mistake made by all bibliometricians is that they fail to consider the content of papers, because they have no desire to understand research.” This arguably needs a citation and at least one cohort of bibliometricians to take an IQ test to establish if bibliometrics really are “for people who aren’t prepared to take the time (or lack the mental capacity) to evaluate research by reading about it.” I can’t necessarily back up with a citeable source myself but I’m willing to bet that the very first thing one learns as a bibliometrician is the strengths and, often profound, weaknesses of the various metrics, whether JIF, h-index or alternative. To dismiss their value entirely seems to rather throw the baby out with the bathwater.

Not that I don’t have reservations – the colour coded donut of altmetric.com surrounding a number arguably lacks clarity and I’m not entirely certain what the number actually refers to, though it seems to correlate vaguely with tweets (coloured blue in the donut) which is invariably the highest “metric” – and arguably the least valuable – there is presumably some weighting towards potentially more valuable, less ephemeral activity on blogs (yellow) and in mainstream news outlets (dark red). I’m not convinced Mendeley and CiteULike necessarily reflect representative networks across all disciplines (dark red and light blue respectively) or Facebook for that matter (dark blue)…however, this is surely the point, the network, and while altmetrics do perhaps pander to a human propensity to quantify with raw numbers – though no more than traditional citations – their main strength is undoubtedly to visualise and leverage the network; to connect with peers online, or with interested laypersons, to foster community and promote research activity and impact beyond the walls of the ivory tower.

N.B. I’ve just picked up this article from Twitter – Numbers behind Numbers: The Altmetric Score and Sources Explained…but haven’t read it yet!

Donuts can be embedded easily using code provided at http://api.altmetric.com/embeds.html and the API can be accessed free of charge, with various paid options for more sophisticated functionality, though with a little knowhow you can derive useful data without a subscription to the premium service. There is also a plugin available from the EPrints Bazaar

IRUS_april

Below are the top 10 articles by altmetric for repository downloads in April 2015 as recorded by IRUS-UK and derived from 84 UK repositories and a total of more than 87,000 unique items. Data is presented with a link to the primary repository and highlights numbers of total downloads* from this, and any other repositories where the paper is archived (*i.e. all downloads from each repository, not just April). There is a DOI lookup link and a note whether the article is available to download from the publisher’s site (N.B. only 3 of these 10 are restricted access with 5 under CC-By and 2 freely accessible albeit © All Rights Reserved).

No further analysis is offered other than to say that there does not appear to be any obvious correlation between altmetrics and repository downloads – number 1 is obviously related to a major story in the media about a certain King found in a Leicester carpark – but, it bears reiterating, that is not necessarily the point; rather repositories are an embedded, institutionally managed element of researchers’ online network with tools like IRUS and altmetrics enabling data to be visualised and leveraged across an increasingly coherent infrastructure.

N.B. Information on how this data was derived using the export function from IRUS-UK and a Google Sheet will follow in a subsequent post.
