NAME ^

Redis::Bayes - stochastic Baysian classification on Redis

SYNOPSIS ^

EXAMPLES:

  my $rb = Redis::Bayes->new;
  $rb->train('apple_computer',q{I'm going to pick up a new retina display MacBook!});
  $rb->train('apple_fruit',q{That thing is rotten at the seeds.});
  my $result = $rb->classify("retina display");

DESCRIPTION ^

This module is an implementation of naive Bayes on Redis.

METHODS ^

new

  my $rb = Redis::Bayes->new; # defaults to Redis->new(reconnect => 2, every => 100);
  # or
  my $rb = Redis::Bayes->new(
    prefix => 'yourownprefixhere:',
    stopwords => {blah => 1, whatever => 1},
    redis => $redis,
  );
prefix

Redis database prefix. The default is 'bayes:'.

stopwords

The set of words to filter when training. The default uses Lingua::StopWords.

redis

Defaults to Redis->new(reconnect => 2, every => 100). Otherwise, use delegation here.

train

  $rb->train('apple','sauce');

Train using <label, document>.

untrain

  $rb->untrain('apple','sauce');

Untrains <label, document>.

flush

  $rb->flush;

Flushes all trained data.

classify

  $rb->classify(q{there's a computer on the desk});

Returns the label with the highest confidence metric for the given document.

ACKNOWLEDGEMENTS ^

This module is ported loosely from other such packages in node and python, i.e. https://github.com/harthur/classifier and https://github.com/jart/redisbayes and https://github.com/didip/bayes_on_redis, with some modifications.
