This document provides an overview of using hyperlink network analysis to study political communication online. It discusses differences between hyperlinking practices in Web 1.0 (static websites) versus Web 2.0 (blogs) in South Korea. Analysis of South Korean politicians' websites from 2000-2001 and their blogs from 2005-2006 found that linking became more decentralized and dense over time. The document also summarizes a case study of the 2007 South Korean presidential primary which found cyber-balkanization between the two main candidates' sites based on a co-link analysis using Yahoo. It concludes by discussing the role of search engines in political communication research using large-scale hyperlink data.

2. Three topics for today
• Is a hyper-linking socio-political or
technical behavior?
• How different/similar are hyper-linking
practices between Web 1.0 and Web
2.0?
• What are advantages of massively-
collected hyper-link data using search
engines for political and electoral
communication research?

3. A comment from those who are
NOT doing a link analysis
• In a chapter of The Sage Handbook of
Online Research Methods edited by
Fielding et al. (2008), Horgan emphasizes
that „link analysis‟ has become an active
research domain in examining social
behavior online.

Years on from the “Internet Election”. Journal of Contemporary Eastern Asia. 7
(1), 1-4.
Lee, Y.-O., & Park, H. W. (2010 forthcoming). The Reconfiguration of E-
Campaign Practices in Korea: A Case Study of The Presidential Primaries of
2007. International Sociology.
Park, H. W. (2009, work-in-progress). How do social scientists use link data
from search engines to understand Internet-based political and electoral
communication.
32
33. Background & Data collection
• The Internet represents a massive
storehouse of social networking data,
enabling researchers to capture political
communications by individual officials,
politicians, and activists.
• This is particularly true in South Korea, where
political participants almost always have
online representation.
• Hyper-linking maps are indicative of the
relative level of public awareness and the
ideological orientation of candidates and
parties.
33
34. The 2007 presidential race within
the opposition Grand National Party
• Profiles of candidates
– Two major candidates:
Myung-Bak Lee and Geun-
Hye Park
• MB Lee is ex-mayor of Seoul
and ex-CEO of Hyundai
• GH Park is a daughter of ex-
president Jeong-Hee Park
– Two minor candidates but
the two major candidates
were selected for this
research
35. Difference between public opinion survey
and actual turnout in GNP primary
• Contrary to public opinion
survey, Park ran neck-and-
neck with Lee
– Lee defeated Park only by
1.5% point (2,452 votes)
– Furthermore, Park obtained
423 votes more than Lee
from delegates, party
members, and invited non-
partisan participants

36. Affiliation network diagram using pages
linked to Lee’s and Park’s sites
N = 901 (Lee: 215, Park: 692, Shared: 6)
37. Findings & Discussions
• Cyber-balkanization was observed.
– Only a few webpages/sites are shared between
the two campaign sites.
– The campaign sites tend to attract links from like-
minded sites.
• The case study can be taken as an ‘evidence’
to show the existence of the theoretical
correlation between the result of this
particular election and hyperlink network
analysis
38. Data collection for
the 2007 presidential election
• Co-(in)link analysis of the 20 websites of
the candidates/parties using the Yahoo
– Also web size, incoming links, visitor traffic
• Qualitative complements
• Particularly usefulness: Public opinion
surveys could not be published within six
days before the 2007 election

44. Discussions
Should hyperlink data collection be always
conducted using (commercial) search
engines?
How do we know the extent to which a
search engine influences/distorts
research results? Is search engine value-
free research tool?
44
45. My answer is
• Science organizes, structures, and evaluates
information to develop a systematic body of
knowledge.
• It is up to the researcher to draw the
appropriate conclusions, using his or her
expertise, about the information gathered
from the web using search engines.
• While search engines collect data from the
entire web, finding the truth from the
information is the business of academics
