• Search for papers with “Ebola” and “Liberia”

http://www.nytimes.com/2015/04/08/opinion/yes-we-were-warned-about-ebola.html

We were stunned recently when we stumbled across an article by European researchers in Annals of Virology [1982]: “The results seem to indicate that Liberia has to be included in the Ebola virus endemic zone.” In the future, the authors asserted, “medical personnel in Liberian health centers should be aware of the possibility that they may come across active cases and thus be

prepared to avoid nosocomial epidemics,” referring to hospital-acquired infection.

Adage in public health: “The road to inaction is paved with research papers.”

From Brazil, Life Sciences, works on project about evolution of oncology „I am extremely happy to join this first cohort of ContentMine Fellows. I participated in a

ContentMine workshop in 2014 and have been following the progress of the project ever since, looking for an opportunity to collaborate which now materializes.“

Problem: Get text and metadata out of old conference proceedings and measure the evolution of ideas and practice using entity analysis, especially trends.

Wants: extract facts from cancer research conference papers and global health papers. Extracting topics (innovations, developments) and comparing the two types of publications. Find out which facts from conferences get later on published in articles.

…and 10,000 more

ContentMine software can do this in a few minutes

Polly: “there were 10,000 abstracts and due to time pressures, we split this between 6 researchers. It took about 2-3 days of work (working only on this) to get through ~1,600 papers each. So, at a minimum this equates to 12 days of full-time work (and would normally be done over several weeks under normal time pressures).”

The Royal SocietyData miningWe support the stance that the right to read is the right to mine. We believe that the ability to use computers to extract information from scholarly material is one of many tools available to researchers, and we support this activity on our journals.

Members of subscribing institutions have our permission to mine journal content for either commercial or non-commercial purposes. We ask that you respect the copyright of the original papers, and where possible cite original works when you reuse them.

Text and data mining is an exception to the usual copyright restrictions which researchers can benefit from. The exception (s.29A of the Copyright, Designs and Patents Act 1988 (CDPA)) allows copies to be made of any copyright material for the purpose of computational analysis.

If a researcher wants to share TDM results that contain some copyright-protected element from the original

work, for example in a publication, then that is possible in certain circumstances. For example, the Quotation exception (s.30 of the Copyright, Designs and Patents Act 1988 (CDPA)) allows the copying and use of portions of someone else’s work to illustrate a point being made.

Please also bear in mind that our servers have finite capacity, and to help us manage the system load we ask that you let us know when you intend to carry out any mining activity. Our technology provider sets a limit on downloads from our sites, beyond which an automatic lock-out is triggered. By working together, we can help you to complete your project and achieve your research goals without being blocked by technical restrictions.

Elsevier stopped me doing my researchChris Hartgerink

I am a statistician interested in detecting potentially problematic research such as data fabrication, which results in unreliable findings and can harm policy-making, confound funding decisions, and hampers research progress.To this end, I am content mining results reported in the psychology literature. Content mining the literature is a valuable avenue of investigating research questions with innovative methods. For example, our research group has written an automated program to mine research papers for errors in the reported results and found that 1/8 papers (of 30,000) contains at least one result that could directly influence the substantive conclusion [1].In new research, I am trying to extract test results, figures, tables, and other information reported in papers throughout the majority of the psychology literature. As such, I need the research papers published in psychology that I can mine for these data. To this end, I started ‘bulk’ downloading research papers from, for instance, Sciencedirect. I was doing this for scholarly purposes and took into account potential server load by limiting the amount of papers I downloaded per minute to 9. I had no intention to redistribute the downloaded materials, had legal access to them because my university pays a subscription, and I only wanted to extract facts from these papers.Full disclosure, I downloaded approximately 30GB of data from Sciencedirect in approximately 10 days. This boils down to a server load of 0.0021GB/[min], 0.125GB/h, 3GB/day.Approximately two weeks after I started downloading psychology research papers, Elsevier notified my university that this was a violation of the access contract, that this could be considered stealing of content, and that they wanted it to stop. My librarian explicitly instructed me to stop downloading (which I did immediately), otherwise Elsevier would cut all access to Sciencedirect for my university.I am now not able to mine a substantial part of the literature, and because of this Elsevier is directly hampering me in my research.[1] Nuijten, M.

Chris Hartgerink’s blog post

http://onsnetwork.org/chartgerink/2016/02/23/wiley-also-stopped-my-doing-my-research/

Wiley also stopped me (Chris Hartgerink) doing my researchIn November, I wrote about how Elsevier wanted me to stop downloading scientific articles for my research. Today, Wiley also ordered me to stop downloading.

As a quick recapitulation: I am a statistician doing research into detecting potentially problematic research such as data fabrication and estimating how often it occurs. For this, I need to download many scientific articles, because my research applies content mining methods that extract facts from them (e.g., test statistics). These facts serve as my data to answer my research questions. If I cannot download these research articles, I cannot collect the data I need to do my research.I was downloading psychology research articles from the Wiley library, with a maximum of 5 per minute. I did this using the tool quickscrape, developed by the ContentMine organization. With this, I have downloaded approximately 18,680 research articles from the Wiley library, which I was downloading solely for research purposes.Wiley noticed my downloading and notified my university library that they detected a compromised proxy, which they

had immediately restricted. They called it “illegally downloading copyrighted content licensed by your institution”. However, at no point was there any investigation into whether my user credentials were actually compromised (they were not). Whether I had legitimate reasons to download these articles was never discussed. The original email from Wiley is available here.

As a result of Wiley denying me to download these research articles, I cannot collect data from another one of the big publishers, alongside Elsevier. Wiley is more strict than Elsevier by immediately condemning the downloading as illegal, whereas Elsevier offers an (inadequate) API with additional terms of use (while legitimate access has already been obtained). I am really confused about what the publisher’s stance on content mining is, because Sage and Springer seemingly allow it; I have downloaded 150,210 research articles from Springer and 12,971 from Sage and they never complained about it.
