This document summarizes a presentation about using information visualization in scientometrics. It discusses how visualization can be used to analyze and understand scientometrics data at different levels, from individual to global. It provides examples of tools like Sci2 that can perform network analysis and visualization of scientometrics datasets. Sci2 allows input of various data formats and visualization of temporal, geospatial, topical and network patterns in scientometric data.

3. It looks like a swirl. There are smaller swirls at the edges. It
has different shades of red at the outside, and is mostly
green at the inside. The smaller swirls have purple highlights.
The green has also different shades. Each small swirl is
composed of even smaller ones. The swirls go clockwise.
Inside the object, there are also red highlights. Those have
different shades of red also. The green shades vary in a fan,
while the purple ones are more uni-color. The green shades
get darker towards the outside of the fan......

5. Visualisation
● Understanding and seeing.
● Defination of visualisation :
– The use of computer-supported, visual
representation of data to amplify cognition
● The purpose of visualisation is insight not the
picture.
6. Visualisation (continued...)
● Visualization is a generic concept in which two
specific domains are distinguished
– Scientific Visualisation = Visualistion applied to
physical data
● Human body, the earth, molecules or other.
– Information Visualisation = Visualisation applied to
abstract data
● For example computer file systems, databases,
documents, stocks etc.
10. Why Information Visualisation
● Visualisation
– Enhance cognition
– Answer questions
– Generate hypotheses
– Make decisions
– See data in context
– Expand memory
– Support computational analysis
– Find patterns
– Tell a story
19. Different Types of Analysis
(continued...)
● Network Analysis (With Whom)
20. Different Levels of Analysis
● Micro
Individual Level
● Meso/Local
Group Level
● Macro/Global
Population Level
21. Types of Visualisation
(Reference System)
1.Charts: No reference system—e.g., Wordle.com, pie charts
2. Tables: Categorical axes that can be selected, reordered; cells can be color coded and
might contain proportional symbols. Special kind of graph.
3. Graphs: Quantitative or qualitative (categorical) axes. Timelines, bar graphs, scatter
plots.
4. Geospatial maps: Use latitude and longitude reference system. World or city maps.
5. Network graphs: Node position might depends on node attributes or node similarity. Tree
graphs: hierarchies, taxonomies, genealogies. Networks: social networks, migration flows.
22. Graphic Variable Types
(Representation of Data Attributes)
●
Position
– X, Y and possibly Z Quantitative
●
Form
– Size Quantitative
– Shape Qualitative
●
Color
– Value (Brightness) Quantitative
– Hue Qualitative
– Saturation Quantitative
●
Texture
– Pattern, Rotation, Density Gradient Quantitative
●
Optics
– Crispness, Transparancy, Shading Qualitative

26. Scientometrics
● Scientometrics is the study of measuring and
analysing science, technology and innovation.
● Scientometrics involves studies in
– History of science
– Growth of science and scientific institutions
– Behaviour of science and scientists.
– Science policy and decision making
27. Purpose of Scientometrics
● Citation mapping .
● Visualization of the bibliographic coupling among authors .
● Identifying patterns and trends in scientific literature.
● Bibliographic analysis .
28. Information Visualisation of
Scientometrics Data
● Visualisation of scientometrics data helps us to
answer questions such as
– What are the major research areas, experts,
institutions, regions, nations, grants, publications?
– Which areas are most insular?
– What are the main connections for each area?
– What is the relative speed of areas?
– Which areas are the most dynamic/static?
– What new research areas are evolving?
– How does funding influence the number and quality of
publications?

41. Conclusion
● Information Visualisation can be used in many
different fields.
● There are a number of recently developed
visualization techniques.
● Different technique is used according to user
need and data types.
● Wrong visualistion representation can mislead
interpretation.
