Processing
• Processing in Apache Zeppelin, a
Python-enabled platform for the
deployment of multi-purpose
research notebooks.
• Notebooks are hybrid interactive
environments, designed for
computational tasks, including
ingestion, analysis and visualization
of data.
• Three notebooks available on Zepl,
a platform for data exploration:
• Statistics, general statistics
overview
• Timelines, progress through time
• Networks, connections of authors,
sources and access types

part 2: timelines
timelines of publications, authors & sources / access type / funding and
document type . life cycles of authors per access type . expansion rates of
authors . time variations of authors & sources . rates of continuity or lapse for
authors & sources
zepl notebook https://bit.ly/31VON8I
timelines: publications, authors & sources
timelines: access type
lifecycles: authors
Excluding 2018, the majority of the authors in our sample publish only once
and then disappear (83%, 2017). First time authors have a highest at (27.6%,
2004), where as 2016 was a "draining" year (11.3%).
expansion rates: authors
The ratio of First Time Authors and the One-Off Authors in a year to all existing
authors in a year.
time variations: top authors
Access type of the publications of 22 authors with at least 10 publications each
one. Paywalled and Bronze are consistent, while Gold and Bronze are preferred
in the "burst year" of 2018.
time variations: top sources
Access type of publications in nine sources with at least 30 publications each
one. Deeper views on Document Type show that Editorials and News Item play
significant role.
part 3: networks
bipartite graph of authors-publications . co-authorship graph . bipartite graph
of authors-access type . access assortativity of the co-authorship graph
zepl notebook https://bit.ly/31VON8I
• The bipartite graph of publications and
authors has 8.505 nodes (5.659 authors
and 2.846 publications) and 7.248 edges
(authorships).
• The largest connected component has 590
nodes (447 authors and 143 publications)
and 732 edges (authorships).
networks: authors & publications
• The bipartite graph of authors and access
type has 5.663 nodes (5.659 authors and
four access types) and 6.666 edges.
• Both Paywalled and Bronze group into
large clusters of authors.
• A third cluster of authors is shared
between Green and Gold.
• Gold OA authors have the least ties with
other access types.
networks: authors & access types
Some conclusions
• "Open Access" is semantically ambiguous term / similar terms in medical
informatics, electrical engineering, rural planning and land management,
drug policies, fishery, etc. / manual cleaning is needed, but not perfect.
• We observed similar growth trends like in other fields / steady growth after
2004 > upscaling after 2012.
• We also observed that the field is expanding / there are many occasional
authors / few are the consistently publishing ones / fresh authors represent
approx. 10% each year.
• Bronze publications appear as an opportunity to work further on training.
thank you for your attention

  • 15. lifecycles: authors Excluding 2018, the majority of the authors in our sample publish only once and then disappear (83%, 2017). First time authors have a highest at (27.6%, 2004), where as 2016 was a "draining" year (11.3%).
  • 16. expansion rates: authors The ratio of First Time Authors and the One-Off Authors in a year to all existing authors in a year.
  • 17. time variations: top authors Access type of the publications of 22 authors with at least 10 publications each one. Paywalled and Bronze are consistent, while Gold and Bronze are preferred in the "burst year" of 2018.
  • 18. time variations: top sources Access type of publications in nine sources with at least 30 publications each one. Deeper views on Document Type show that Editorials and News Item play significant role.
  • 19. part 3: networks bipartite graph of authors-publications . co-authorship graph . bipartite graph of authors-access type . access assortativity of the co-authorship graph zepl notebook https://bit.ly/31VON8I
  • 20. • The bipartite graph of publications and authors has 8.505 nodes (5.659 authors and 2.846 publications) and 7.248 edges (authorships). • The largest connected component has 590 nodes (447 authors and 143 publications) and 732 edges (authorships). networks: authors & publications
  • 21. • The bipartite graph of authors and access type has 5.663 nodes (5.659 authors and four access types) and 6.666 edges. • Both Paywalled and Bronze group into large clusters of authors. • A third cluster of authors is shared between Green and Gold. • Gold OA authors have the least ties with other access types. networks: authors & access types
  • 22. Some conclusions • "Open Access" is semantically ambiguous term / similar terms in medical informatics, electrical engineering, rural planning and land management, drug policies, fishery, etc. / manual cleaning is needed, but not perfect. • We observed similar growth trends like in other fields / steady growth after 2004 > upscaling after 2012. • We also observed that the field is expanding / there are many occasional authors / few are the consistently publishing ones / fresh authors represent approx. 10% each year. • Bronze publications appear as an opportunity to work further on training.
  • 23. thank you for your attention addendum at DOI 10.17605/osf.io/u7azn
