Group exploration:

Get together in groups of three (similar field of interest

preferred)

Go to http://openknowledgemaps.org/mozfest

and visualize a PLOS search!

Discuss the results that you got

Static visualization of all of science

[Bollen et al. 2009]

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

Page 15: The Student's and Researcher's Guide to Discovery: Exploring Scientific Fields with Open Data and Tools

15

Challenge 1: Availability of open data – Bibliographic

data

Danowski et al. (2013)

Page 16: The Student's and Researcher's Guide to Discovery: Exploring Scientific Fields with Open Data and Tools

16

Challenge 2: Availability of open data –

Bibliometric data & full text

Page 17: The Student's and Researcher's Guide to Discovery: Exploring Scientific Fields with Open Data and Tools

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)

Page 18: The Student's and Researcher's Guide to Discovery: Exploring Scientific Fields with Open Data and Tools

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)

Vision: Collaborative visualizations of all of science

based on open data
