enron: Enron Email Network

Description

An Enron email dataset has been made public by the U.S. Department of Justice.

Usage

enron

Arguments

Format

A directed igraph graph object. Graph attributes:
  • ‘LDC_names’ The names of the 32 LDC catagories the emails are classfied into by Michael W. Berry (http://www.cis.jhu.edu/~parky/Enron/Anno_Topic_exp_LDC.pdf)
  • ‘LDC_desc’ Longer descriptions of the 32 LDC categories.
  • ‘Citation’ Additionally, see also the references below.
  • ‘name’
Vertex attributes:
  • ‘Email’ Email address.
  • ‘Name’ Real name.
  • ‘Note’ E.g. position at Enron.
Edge attributes:
  • ‘Time’ When the email was sent. Note that some time labels are from 1979, these are certainly wrong and you might want to remove them before analyses that include time.
  • ‘Reciptype’ Recipient type, ‘to’, ‘cc’ or ‘bcc’.
  • ‘Topic’ Assigned based on 3-means clustering of randomly selected 3,120 out of all 125,409 messages, then NN classification for the whole corpus. Note that topic 0 means an outlier, e.g., too few words or all meaningless numbers in the message body.
  • ‘LDC_topic’ Assigned based on Michael W. Berry's 2001 “Annotated (by Topic) Enron Email Data Set.” (http://www.cis.jhu.edu/~parky/Enron/Anno_Topic_exp_LDC.pdf) There are 32 topics. Topic "0" means an outlier, e.g., too few words or all meaningless numbers in the message body, etc. Topic "-1" means there is no matching topic.
