Spam Assassin public mail corpus.
npm install @stdlib/datasets-spam-assassinWe believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js. The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases. When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there. To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!

> The [Spam Assassin][spam-assassin] public mail corpus.
``bash`
npm install @stdlib/datasets-spam-assassin
`javascript`
var corpus = require( '@stdlib/datasets-spam-assassin' );
#### corpus()
Returns the [Spam Assassin][spam-assassin] public mail corpus.
`javascript`
var data = corpus();
// returns [{...},{...},...]
Each array element has the following fields:
- id: message id (relative to message group)group
- : message groupchecksum
- : object containing checksum infotext
- : message text (including headers)
The message group may be one of the following:
- easy-ham-1: easier to detect non-spam e-mails (2500 messages)easy-ham-2
- : easier to detect non-spam e-mails collected at a later date (1400 messages)hard-ham-1
- : harder to detect non-spam e-mails (250 messages)spam-1
- : spam e-mails (500 messages)spam-2
- : spam e-mails collected at a later date (1396 messages)
The checksum object contains the following fields:
- type: checksum type (e.g., MD5)value
- : checksum value
`javascript
var corpus = require( '@stdlib/datasets-spam-assassin' );
var data;
var i;
data = corpus();
for ( i = 0; i < data.length; i++ ) {
console.log( 'Character Count: %d', data[ i ].text.length );
}
