Spam email datasets
Welcome to the CSDMC2010 SPAM corpus, which is one of the datasets for the data mining competition associated with ICONIP 2010.
This dataset is composed of a selection of mail messages, suitable for
use in testing spam filtering systems.
- All headers are reproduced in full. Some address obfuscation has taken place, and hostnames in some cases have been replaced with "csmining.org" (which has a valid MX record) and with most of the recipents replaced with 'hibody.csming.org' In most cases though, the headers appear as they were received.
- All of these messages were posted to public fora, were sent to me in the knowledge that they may be made public, were sent by me, or originated as newsletters from public mail lists. A part of the data is from other public corpus(es), however, for some reason, information will be open after the competion.
- Copyright for the text in the messages remains with the original senders.
The corpus file -- CSDMC2010_SPAM.tar.bz2
On Linux platforms, it can be extracted by command tar -xjf CSDMC2010_SPAM.tar.bz2 -C email/
In an MS Windows environment, use the bzip2 software http://gnuwin32.sourceforge.net/packages/bzip2.htm
The corpus description
The dataset contains two parts:
- TRAINING: 4327 messages out of which there are 2949 non-spam messages (HAM) and 1378 spam messagees (SPAM), all received from non-spam-trap sources.
SPAMTrain.label contains the labels of the emails, with 1 stands for a HAM and 0 stands for a SPAM.
- TESTING: 4292 messages without known class labels.
The email format description
The format of the .eml file is definde in RFC822, and information on recent standard of email, i.e., MIME (Multipurpose Internet Mail Extensions) can be find in RFC2045-2049.
On the provide python script
Since some data mining techniques only make use of the subject and body of the email to identify spam. In this package, we have included a simple python script (ExtractContent.py) which can help to extract the subject and body of the email.
In a python compatible environment, ( the code is test on python 2.5.1 and should work on python 2.x)
1, invoke the script by command ./ExtractContent.py
2, input source directory -- where you store the source files For exmaple C:\EMAILPro\CSDMC2010_SPAM\TEST
3, input destination directory -- where you want the extracted body to be For example C:\EMAILPro\CSDMC2010_SPAM\TEST_NEW
4, we are done
Note that, the script only extract limited information from the email (no information of fields like to, from, attachment are extract but only the subject and the first part of the body.) By oferring such a script we just want to show a simple preprocessing mehtod where the participants can start from. More advanced method which makes use of email header information or even attachment information are encouraged.
