安然电子邮件数据集包含大约50万封来自约150位用户的电子邮件。

The Enron E-mail data set contains about 500,000 e-mails from about 150 users.

项目思路：

你能对电子邮件的文本进行分类以确定是谁发送的吗？

该数据集是由CALO项目（一个学习和组织的认知助手）收集和准备的。

This dataset was collected and prepared by the CALO Project (A Cognitive Assistant that Learns and Organizes). 

它包含大约150位用户的数据，大部分是安然公司的高级管理层，这些用户被组织存储到文件夹中。

It contains data from about 150 users, mostly senior management of Enron, organized into folders. 

该数据集总共包含约50万条消息。

The corpus contains a total of about 0.5M messages. 

这些数据最初由联邦能源监管委员会在调查期间公布并发布到网络上。

This data was originally made public, and posted to the web, by the Federal Energy Regulatory Commission during its investigation.

该电子邮件数据集后来由麻省理工学院的Leslie Kaelbling购买，结果发现它存在一些完整性问题。

The email dataset was later purchased by Leslie Kaelbling at MIT, and turned out to have a number of integrity problems. 

SRI的一些研究者，特别是Melinda Gervasio，努力纠正这些存在的问题，正是由于他们的不懈努力，数据集才可用于有效的分析。

A number of folks at SRI, notably Melinda Gervasio, worked hard to correct these problems, and it is thanks to them (not me) that the dataset is available. 

这些公开的数据集不包括附件，并且某些敏感消息已被删除，“因为受相关员工的请求，作为编辑整理工作的一部分”。

The dataset here does not include attachments, and some messages have been deleted "as part of a redaction effort due to requests from affected employees".
