MathGroup Emails Network

Network of emails sent to the MathGroup list in November 2011

Network of emails sent to the MathGroup list in November 2011. An edge from user A to user B means that an email from A was sent in reply to B. For each email, the author is stored in the "Author" annotation, the date in "Date", and the message subject in "Subject".

Examples

Basic Examples

Retrieve the graph:

In[1]:=
ResourceData["MathGroup Emails Network"]
Out[1]=

Summary properties:

In[2]:=
ResourceData["MathGroup Emails Network", All]["Summary"]
Out[2]=

Basic Applications

Pick the author with the most received emails:

In[3]:=
g = ResourceData["MathGroup Emails Network"];
In[4]:=
author = First[MaximalBy[VertexList[g], VertexInDegree[g, #] &]]
Out[4]=

Visualize the graph around the author:

In[5]:=
NeighborhoodGraph[g, author, Sequence[
 VertexLabels -> Automatic, VertexStyle -> (author -> Red)]]
Out[5]=

Find the subject of the emails:

In[6]:=
PropertyValue[{g, author}, "Subject"]
Out[6]=
