KDViz of a Subject Domain: Document Co-citation Analysis of Vulnerability 1993-2012

This shows the development of the Document Co-citation Network of the top 65 results derived from WoS dataset.  This network is based upon source articles receiving 5 or more citations.

Image 1. This shows the development of the Document Co-citation Network of the top 65 results derived from WoS dataset. This network is based upon source articles receiving 5 or more citations (click on image to show animation sequence of 4-year intervals starting with the 1993-2012 Merged Network, then going back to 1993-1996, 1997-2000, etc.).

I am currently working on a 1430 article dataset pulled from WoS with a search for  “vulnerability” and “disaster” in the topic, published 1993-2012.

In these visualizations I am using some of the different features of CiteSpace II, including specifying a citation criteria for the source articles, pruning algorithms, and adding source article keywords and text to  the network visualizations.  Here are some of the KDViz images:

Derived from source articles receiving 5 or more citations (n=424) with time frame into six four- year slices.  Size of nodes and labels proportional to total citations received.

Image 2. Derived from source articles receiving 5 or more citations (n=420) with time frame into six four- year slices. Size of nodes and labels proportional to total citations received. Color of co-citation links: Dark blue =1993-1996; Turquoise= 1997-2000; Green=2001-2004; Yellow=2005-2008; Orange=2009-2012.

This is the same DCA as above, but this time the Multiple Spanning Tree (MST) algorithm has been applied to reduce the links to the most essential.

Image 3. This is the same DCA as above, but this time the Minimum Spanning Tree (MST) algorithm has been applied to reduce the links to the most essential. The upper part of the network relates primarily to work in psychology and psychiatry to vulnerability to psychological illness following disasters.

Here is the network of both the most frequently cited articles AND most frequent index terms appearing in the source articles.  Thus, this shows both the knowledge base (cited articles) and the areas of research (index terms) that made up the research fronts at different points during 1993-2012.

Thus, this shows both the knowledge base (cited articles) and the areas of research (index terms) that made up the research fronts at different points during 1993-2012.

From this preliminary analysis, here are the top 25 cited references in articles on Vulnerability (based on total citations):

Here is a view of the works with network centrality values of 0.10 or above, indicating potentially important works.  In CiteSpace II, these nodes are indicated by a pink ring, with the thickness of the ring based on the centrality value.  These centrality values have been calculated from  the network of the Top 65 without the application of a pruning algorithm (shown in Image 2).  Two works (the DSM-III and DSM-IV used for psychiatric diagnoses) have been removed from the list.  Their appearance should be expected in the disaster mental health side, but they do not necessarily add to the analysis.

As I complete additional visualizations and results, including the ACA and JCA, I will add pages to this section.
