mapping of the social sciences (SoSCI 2001)

 <http://www.leydesdorff.net/sosci01/art> Top-down decomposition of the
Journal Citation Report of the Social Science Citation Index:
Graph- and  <http://www.leydesdorff.net/sosci01/art> factor-analytical
approaches

The aggregated journal-journal citation matrix of the Journal Citation
Report 2001 of the Social Science Citation Index is analyzed as a single
domain in terms of both its eigenvectors and the bi-connected components
contained in it. The traditional disciplines (e.g., economics,
psychology, or political science) can be retrieved using both methods.
These main disciplines do interact marginally. The space between them is
occupied by a large number of small clusters of journals indicating
specialties that gravitate among the major disciplines. These
specialties operate in a mode different from that of the disciplines.
For example, the impact factors are low on average and the developments
remain volatile. Factor analysis enables us to study how the smaller
bi-connected components are related to the larger ones.
