Traditional Research/Publication Process

•  Doing research, describe final results in paper •  Paper submitting to Conference / Journal / Book

•  Established publishers: IEEE, ACM, Elsevier, Springer •  Top Journals: Nature, Science, .. •  Top Conferences: WWW, SIGIR, WSDM, CIKM,...

•  Paper gets reviewed – peer review (single blinded, double blinded) à accepted or rejected

•  If accepted and paper will be published •  Often, copyright is transfered to publisher •  Authors/universities need to pay to access paper

8

www.tugraz.at n

Open Research/Publication Process

•  Doing research, documenting interim results online •  Collaboration with others, raising questions, etc.

•  E.g. Source code in Open Source repository •  E.g. bitbucket, github,..

•  E.g. publish data in data repository (e.g. figshare) •  Publish pre-final version in preprint archive: e.g.

arxiv.org •  Ideally - publish final paper in Open Access journal

Importance of Open Data •  Big and open data estimated to add 1.9% of EU-28

GDP by 2020 (EC, 2014) •  New knowledge from combined data sources and

patterns in large data volumes •  In general: limited access to scientific information

strong impact on competitiveness of SMEs!

•  User enabled to make informed decisions •  Users enabled to get insights into governmental and

global public data à transparency and democratic control

Open Data in Science

•  Focus on publishing observations and results of scientific activities available for anyone to analyse and reuse.

•  Idea exists since 1950s à Internet has boosted this: low cost and time required to publish or obtain data.

“Openly accessible research data can typically be

accessed, mined, exploited, reproduced and disseminated, free of charge for the user.”

Guidelines on Open Access to Scientific Publications and Research Data in Horizon 2020, p3

Another point for Open Data

“There is evidence that studies that make their data

available do indeed receive more citations than similar studies that do not.”

Piwowar H. and Vision T.J 2013 "Data reuse and the open data citation advantage“

Characteristics of Open Data

•  Availability and Access: data must be available at reasonable reproduction cost (basically, only downloading). Data must also be available in a convenient and modifiable form.

•  Reuse and Redistribution: data must be provided under terms that permit reuse and redistribution including combination with other datasets.

•  Universal Participation: everyone must be able to use, reuse and redistribute. For example, ‘non-commercial’ restrictions that would prevent ‘commercial’ use, or restrictions of use for certain purposes (e.g. only in education), are not allowed.

Interoperability – Key for Open Data

29

Structured: machine-readable

logical format

Addressable: URIs

shareable

Licensed/Traceable full provenance

Continuous: maintained accessible

5 Star Deployment Scheme for Open Data by Tim Berners-Lee

30 http://www.w3.org/DesignIssues/LinkedData.html

Available on the web (whatever format) but with an open licence, to be Open Data

Available as machine-readable structured data

as (2) plus non-proprietary format

All plus: Use open standards from W3C (RDF and SPARQL) to identify things

All, plus: Link your data to other people’s data to provide context

Linked Data

www.tugraz.at n

Linked Data •  Enables to create typed links between data from

different sources (Bizer et al., 2009)

31

"Linking Open Data cloud diagram 2014, by Max Schmachtenberg, Christian Bizer, Anja Jentzsch and Richard Cyganiak. http://lod-cloud.net/"

www.tugraz.at n

Principles of Linked Data 1.  Use URIs as names for things

(Uniform Resource Identifier): string of characters to identify a name or a resource on the Internet.

2.  Use HTTP URIs so people can look up these names 3.  When someone looks up a URI, provide useful

(RDF) information 4.  Include RDF statements that link to other URIs so

that they can discover related things Tim Berners-Lee 2007 http://www.w3.org/DesignIssues/LinkedData.html

à  Linked Data allows sharing and use of data, ontologies and various metadata standards

32

www.tugraz.at n

Excurse: Resource Description Framework (RDF) •  Data model to describe “things” and their interrelations

•  subject-predicate-object expressions (triples) •  Data items identified by URIs

•  Can be queried by SPARQL

For example: <Edith> <was born in> <Graz> <Graz> <is part of> <Austria>

<Michael> <likes> <Iron Maiden>

www.tugraz.at n

Example: Linked Open Science

•  LinkedScience.org: scientific data as Linked Data •  Showcase: Deforestation and its related phenomena

•  Linked Brazilian Amazon Rainforest Data, enables to explore spatial and temporal data

Peer Review vs. Open Peer Review

•  Traditional review: editor (researcher, journal staff member in the case of journals like Nature) sends paper to experts in the field, who provide comments for the paper

•  Single blind: reviewers can see who the authors are

•  Double blind: reviewers don‘t see who authors are, only editor knows everyone’s identity

35

http://blog.f1000research.com/2014/05/21/what-is-open-peer-review/

www.tugraz.at n

Peer Review vs. Open Peer Review

•  Open peer review: everybody sees everybody‘s names

•  Sometimes: involves publicly naming reviewers and/or editors.

•  Some journals publish some or all reviewer comments

36

www.tugraz.at n

Benefits of Open Peer Review

•  Benefits for authors and readers •  Author can see who reviewed their work •  Reduces bias among reviewers •  More constructive reviews •  Published reports can serve as peer review examples

for young researchers. •  Benefits for reviewers

•  Shows the reviewer’s informed opinion of the work •  Demonstrates experience as a reviewer •  Can take credit for the work involved in conducting the

review

Challenges

•  Current system of scientific publishing works against maximum dissemination of scientific data underlying publications

•  inability to access data, •  restrictions on usage applied by publishers or data

providers, •  publication of data that is difficult to reuse •  cultural reluctance to publish data openly, for multiple

reasons

Open Access

40

“Open Access stands for unrestricted access and

unrestricted reuse.”

Definition by Public Library of Science (PLoS) https://www.plos.org/about/open-access/

www.tugraz.at n

Open Access (OA): Motivations

•  Idea: Research funded by the public should be available to the public (ethical)

•  OA for a variety of research outputs: e.g. Journals, books, papers, datasets

•  OA publications will have more accesses (readers), citations and therefore impact (Research Impact)

•  Concern over the hindrance to research caused by the cost of journal subscriptions (cost)

Source: Jeffery, K. Open Access: An Introduction, 2006. http://www.ercim.eu/publication/Ercim_News/enw64/jeffery.html

www.tugraz.at n

Open access

•  Began with the community •  Driven by organizations (PLOS, F1000, Mendeley etc.)

and policies and funders, first not by academic institutions •  Development of OA licences:

•  E.g. Creative Commons Attribution (CC BY) license: developed to facilitate open access: à free immediate access to, and unrestricted reuse of, original works of all types. Under this license, authors agree to make articles legally available for reuse, without permission or fees, for virtually any purpose. Anyone may copy, distribute or reuse these articles, as long as the author and original source are properly cited.

Open Access in Science: Open Access Journals ●  Green („self-archiving): author can self-archive at the time of

submission of the publication whether the publication is grey literature (usually internal non-peer-reviewed), a peer-reviewed journal publication, a peer-reviewed conference proceedings paper or a monograph

●  Gold („author pays“): the author or author institution can pay a fee to the publisher at publication time, the publisher then makes the publication available 'free' at the point of access .

●  further little-used “road” hybrid forms: for example platinum open access (does not charge author fees)...

●  Both green and gold are compatible and can co-exist

Example: arXiv.org (1/2) •  Open Access electronic archive and

distribution server for research articles, founded in 1991

•  Maintained by Cornell University Library •  Areas: physics, mathematics, computer

science, nonlinear sciences, quantitative biology, statistics à 127 categories

•  Users can retrieve papers from arXiv via web

•  Registered users can submit their papers to arXiv

•  Can be updated, previous versions remain available

•  Highly popular: number of scientific papers posted to Arxiv.org steadily grows, number of readers as well

www.tugraz.at n

Example: arXiv.org (2/2)

•  approx. 1 Mio publications

•  No peer-review •  Submission:

validated either through endorsement by established author or if from trusted IP

www.tugraz.at n

Example: Analyzing arXiv with rOpenSci

•  rOpenSci: has an interface to the arXiv API, package aRxiv (install via CRAN) https://github.com/ropensci/aRxiv, http://ropensci.org/tutorials/arxiv_tutorial.html

•  E.g. “How many articles for a discipline in arXiv?” kcmac-elex:~ elex$ r!> library(aRxiv)!> arxiv_cats!> arxiv_count('cat:"cs.CY"') # count papers in category ![1] 1764!> arxiv_count('cat:"quant-ph"')![1] 63257!

Benefits of Open Access

•  Accelerated discovery: researchers can read and build on the findings of others without restriction

•  Public enrichment: Scientific research often paid for

with public funding. Taxpayers enabled to see results •  Improved education: Teachers and students have

access to the latest research findings

Summary

•  Open Science •  Ideas, Concepts, Benefits and Pitfalls

•  E.g. Enhancing collaboration and community-building, increasing efficiency of research vs no reward system yet

•  Open Data •  Sharing your data influences how often you get

cited (Piwowar, et al., 2007 and Pinowar, et a., 2013)

•  Different models for Open Access •  Green vs. Gold vs. Hybrid
