ABSTRACT
After the filing for Chapter 11 bankruptcy by Enron in December of 2001, an unprecedented amount of information (over 1.5 million electronic mail messages, phone tapes, internal documents) was released into the public domain. Such information served the needs of the Federal Energy Regulatory Commission (FERC) in its investigation against Enron. The emails originally posted on the FERC web site (18) had various integrity problems which required some cleaning as well as the removal of sensitive (private) and irrelevant information. Dr. William Cohen and his research group at Carnegie Mellon University have addressed many of these problems in their release of the Enron Email Sets. The version of the Enron Email Sets1 dated March 2, 2004 contains 517, 431 email messages of 150 Enron email accounts covering a period from December 1979 through February 2004 with the majority of messages spanning the three years: 1999, 2000, and 2001.
