In-Depth Information
But, unfortunately, this data is not in a nice graph data format. The typical
target format of graph data will be nicely organized into two data sets—a
table of nodes and a table of links, as shown here:
Nodes:
"Ann"
"Ben"
"Tim"
"Zoe"
Links:
NodeA, NodeB
"Ann", "Ben"
"Ben", "Tim"
"Ben", "Zoe"
"Tim", "Zoe"
Furthermore, the target graph data can be much more useful if it contains
additional information, such as counts, size, and recentness, which may be
used later in the analysis:
Nodes:
Person, Number_of_Emails, Total_kb, Most_Recent_Date
"Ann", 1, 2048, 10/31/2014
"Ben", 4, 7687, 12/09/2014
"Tim", 2, 102, 11/18/2014
"Zoe", 3, 4292, 12/09/2014
Links:
NodeA, NodeB, Number_of_Msgs
"Ann", "Ben", 1
"Ben", "Tim", 2
"Ben", "Zoe", 3
"Tim", "Zoe", 2
Nodes must be extracted from the To, From, and Cc fields. Similarly, links
must be constructed between people within a single row—in the previous
example, the first e-mail represents an e-mail from Zoe to Ben (that is, a
link).
