Overview
Blog network mappingvisualising connections between groups of sites
links, affiliations,friendships, clustersreferences, opposition
for large datasets, enables depictionof non-physical space, make sense of data,(although risk of focussing on 'sciencey'visualisations rather than analysis)
Previous examples
Adamic and Glance (2005)U.S. - 2004 Presidential election
RTGI/linkfluence (2007 - present)France – 2007 Presidential electionU.S. - 2008 Presidential electionEurope – 2009 EU elections
Kelly and Etling (2008)Persian-language
Etling et al. (2009)Arabic blogs
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
Research context
Study of French and Australian politicalblogs (and associated sites)
Data collection: January – August 2009
Data used: blog posts and links
Focus on comparing whole period activityand event- based, topical networks
New directions
1. Types of link
Blogrolls vs. in-text citations(vs. in-text in topical network)(vs. comments, other platforms)

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

3. Mixed methods
Hyperlink analysis + content analysis
locating networks using link data from postsdiscussing particular topic (+ visualisation)
analysing text of posts from individual blogsto identify prominent themes, different approaches to the same topic
4. Geographical representations
Distribution of sites within a link-based networkcompared with geographical distribution of blogs
clustering around major cities?
blogging demographics? (urban/rural?)
Combined with content analysis – different topics beingdiscussed around regions?
5. Beyond the network paradigm?
Hyperlink analysis invites the use of 'networks'...
Other mapping approaches available, depictingprominence of sites (traffic, in-links, rankings),thematic clusters,location, ideologies...
