2. Overview
Blog network mapping
visualising connections between groups of sites
links, affiliations,
friendships, clusters
references, opposition
for large datasets, enables depiction
of non-physical space, make sense of data,
(although risk of focussing on 'sciencey'
visualisations rather than analysis)

3. Previous examples
Adamic and Glance (2005)
U.S. - 2004 Presidential election
RTGI/linkfluence (2007 - present)
France – 2007 Presidential election
U.S. - 2008 Presidential election
Europe – 2009 EU elections
Kelly and Etling (2008)
Persian-language
Etling et al. (2009)
Arabic blogs

4. Strengths
Overview of large/long-term datasets
Identification of clusters/groups, including around themes
or activities
Locate most active sites, popular sources
Weaknesses
Differentiation between types of link, link semantics,
link frequency
Temporal variations – event-oriented peaks or troughs,
context for blog activity

5. Research context
Study of French and Australian political
blogs (and associated sites)
Data collection: January – August 2009
Data used: blog posts and links
Focus on comparing whole period activity
and event- based, topical networks

6. New directions
1. Types of link
Blogrolls vs. in-text citations
(vs. in-text in topical network)
(vs. comments, other platforms)

7. Blogrolls
French political blogs
Jan-Aug 2009
Size:
in-degree
Colour:
out-degree

8. Out-links
French political blogs
Jan-Aug 2009
Size:
in-degree
Colour:
out-degree

9. 2. Dynamics / Snapshots
Isolating posts around particular topics/
people/events
Day-by-day variations,
changes in network over time
Topical references vs. most cited resources overall,
topical blog activity compared to total output during period

10. Out-links
Size:
in-degree
Colour:
out-degree
French political blogs
16-25 January 2009

11. Topical network: Obama inauguration
French political blogs
16-25 January 2009
Size:

Colour:
out-degree

12. 3. Mixed methods
Hyperlink analysis + content analysis
locating networks using link data from posts
discussing particular topic (+ visualisation)
analysing text of posts from individual blogs
to identify prominent themes,
different approaches to the same topic

14. 4. Geographical representations
Distribution of sites within a link-based network
compared with geographical distribution of blogs
clustering around major cities?
blogging demographics? (urban/rural?)
Combined with content analysis – different topics being
discussed around regions?

15. 5. Beyond the network paradigm?
Hyperlink analysis invites the use of 'networks'...
Other mapping approaches available, depicting
prominence of sites (traffic, in-links, rankings),
thematic clusters,
location, ideologies...
