Introduction:
Please say your name and add three hashtags that
describe you:
#1: Your occupation (student, researcher, activist…)
#2: Your current field of interest (biology, open peer
review…)
#3: Of your own choosing
If you can, please also add this to:

Static visualization of all of science
[Bollen et al. 2009]
14
What‘s needed for a knowledge domain
visualization?
14 Know-Center GmbH • Research Center for Data-Driven Business and Big Data Analytics
Bibliographic data of the works in a domain
Bibliometric data/full text of items to find interesting/important
works
Relational data to compute the
similarity between items
Domain experts and classification specialists to evaluate and
adapt the visualizations
15
Challenge 1: Availability of open data – Bibliographic
data
Danowski et al. (2013)
16
Challenge 2: Availability of open data –
Bibliometric data & full text
17
Challenge 3: Usability and usefulness
Most static visualizations are useful to understand the
structure of science, but not in researchers‘ daily work
A lot of the existing tools are made for experts and they
are based on closed data (Web of Science, PubMed)
18
Challenge 4: Systematic bias and algorithmic errors
Characteristics of the underlying dataset influence the
visualizations (Bollen et al. 2008, Kraker et al. 2014)
Algorithmic errors cannot be avoided in automated
systems
Dedicated community of domain experts,
classification specialists, programmers … (think
Wikipedia)
19
Vision: Collaborative visualizations of all of science
based on open data
