{{lowercase|title=dbacl}}
'''dbacl''' is a digramic Bayesian text classifier. Given some text, it calculates the posterior probabilities that the input resembles one of any number of previously learned document collections. It can be used to sort incoming email into arbitrary categories such as spam, work, and play, or simply to distinguish an English text from a French text. It fully supports international character sets, and uses sophisticated statistical models based on the [[wikipedia:Principle of maximum entropy|Maximum Entropy Principle]].

==Usage==
===Simple example===
<tt>dbacl</tt> has two major modes of operation. The first is learning mode, where one or more text documents are analysed to find out what make them look the way they do. At the shell prompt, type (without the leading %)

% dbacl -l one sample1.txt
% dbacl -l two sample2.txt

This creates two files named <code>one</code> and <code>two</code>, which contain the important features of each sample document.

The second major mode is classification mode. Let's say that you want to see if <code>sample3.txt</code> is closer to <code>sample1.txt</code> or <code>sample2.txt</code>; type

% dbacl -c one -c two sample3.txt -v
one # <-- output

and <tt>dbacl</tt> should tell you it thinks <code>sample3.txt</code> is less like <code>two</code> (which is the category learned from <code>sample2.txt</code>) and more like <code>one</code> (which is the category learned from <code>sample1.txt</code>).
