Enron Corpus
The Enron Corpus is a large database of over 600,000 emails generated by 158 employees of the Enron Corporation and acquired by the Federal Energy Regulatory Commission during its investigation after the company's collapse.〔"(The Enron Email Corpus )" Retrieved March 5, 2011.〕
==History==
The Enron data was originally collected at Enron Corporation headquarters in Houston during two weeks in May 2002 by Joe Bartling, a litigation support and data analysis contractor working for Aspen Systems, now Lockheed Martin, whom the Federal Energy Regulatory Commission (FERC) had hired to preserve and collect the vast amounts of data in the wake of the Enron Bankruptcy in December 2001. In addition to the Enron employee emails, all of Enron's enterprise database systems, hosted in Oracle databases on Sun Microsystems servers, were also captured and preserved including its online energy trading platform, EnronOnline.
Once collected, the Enron emails were processed and hosted in litigation platform Concordance, and then iCONECT, for the investigative team from the Federal Energy Regulatory Commission, the Commodity Futures Trading Commission, and Department of Justice investigators to review. At the conclusion of the investigation, and upon the issuance of the FERC staff report,〔(FERC Staff Report - Price Manipulation in Western Markets - Findings at a Glance ) (3-26-2003)〕 the emails and information collected were deemed to be in the public domain, to be used for historical research and academic purposes. The email archive was made publicly available and searchable via the web using iCONECT 24/7, but the sheer volume of email of over 160GB made it impractical to use. Copies of the collected emails and databases were made available on hard drives.
A copy of the email database was subsequently purchased for $10,000 by Andrew McCallum, a computer scientist at the University of Massachusetts Amherst.〔Markoff, John. "(Armies of Expensive Lawyers, Replaced by Cheaper Software )". ''New York Times'' March 5, 2011. p A1.〕 He released this copy to researchers, providing a trove of data that has been used for studies on social networking and computer analysis of language.
