Networks of Belief Structures: An Entailment Analysis of the ISSP 2003 National Identity Survey.
See 27th annual INSNA Conference, Abstracts p 156. This paper presents an examination of the ISSP 2003 National
Identity Survey using the network entailment analysis.
The questions in the survey are similar to those in many
other multinational surveys. Examples include questions
about the individual's pride in different aspects of the country,
attachment to institutions, and international relations.
The entailment process uses thresholds of logical implication
to extract cognitive structures in the relationships between
the questions asked. For example, when a majority of respondents
who answer positively to question A also answer
positively to question B, such an entailment relationship is
observed. The pooled results, of 48 different questions, form
signed networks of dyadic relations between the 48 nodes
indicating patterns of positive and negative responses. These
cognitive network graphs are compared over each of the 33
countries included in the ISSP study, and the countries are
clustered by similarities in the entailment networks extracted.
Finally, the entailment structure permits an examination
of the common relationships among responses within
the clusters through extracting the central graphs. This
process compares not only the dominant response patterns
within countries, but between countries as well. Thus, this
method produces a new way of looking at multinational
survey data that incorporates micro level differences in
cognitive structure into a macro level comparison.
