What is Breadth-Oriented Exploration?
Exploring more = Breadth?

Like Talking about A Large Apple…
How large is large?

Why Breadth in Data Exploration?
It is the purpose of exploratory data analysis!
“Exploratory data analysis is detective work.”John W. Tukey

What Causes the Lack of Breadth?
My subconscious mind
These cities look familiar to me and they get high scores.
Let me choose them.

Use of heuristics is a potential causeof lack of breadth in data exploration

Exploring more = Breadth?
A strategy to overcome lack of breadth in exploration due to information overload
How do you design a system to overcome the lack of breadth?
Three Design Considerations:
Unit of ExplorationUser-driven vs System-driven ExplorationRelated vs Systematic Exploration
19
First Consideration: Unit of Exploration
What things to which the system should exposeusers more?
Data case or dimension?
20
21
We may want to look at different combinations of dimensions during exploratory data analysis
Terrorism
Censorship
Education
Exploring the unexplored

Use of Dimensionas a Unit of Exploration
22
1. Showing dimension coverage information

23
2. Showing new dimensions as you explore

How does it apply to a system for exploring the city dataset?
24
Data case as a unit
Users explore cities System recommends cities
LondonParisRome
OsloDusseldorfReykjavik
Second Consideration: User-driven vs System-driven Exploration
25
Information about exploration
Awareness of exploration
Less-biased exploration
Users are responsible for ensuring breadth
Second Consideration: User-driven vs System-driven Exploration
26
Select information to show
Less-biased exploration
System is responsible for ensuring breadth
User-driven vs System-driven Exploration
27
How does it apply to a system for exploring the city dataset? System-driven exploration
Users explore cities

Third Consideration:Related vs Systematic Exploration
Only applies to system-driven exploration…

Some steps you should go through in data analysis

Exploring more = Breadth?
Strategy to overcome lack of breadth in exploration due to information overload
by overloading users with more information???
Paradoxical? Or… is it?Unit of Exploration
What to show
User-driven vs System-driven ExplorationWho is responsible to select
Related vs Systematic ExplorationBased on what to select

Exploring more = Breadth?
Strategy to overcome lack of breadth in exploration due to information overload
by selecting potentially useful information to show
by overloading users with more information???
Sounds Challenging…
How to select to ensure relevance of information and prevent information overload?
