Intro

The plugin brings very easy to use text classification via bayes classifiers to Grails. By default the plugin runs with a simple set up that contains one classifier for all trained text but allows to configure multiple classifiers, word listers (stemmers) by a grouping key. It uses ci-bayes under the hood. ci-bayes allows using different implementation of classifiers (the algorithms on which the classification is based) and word listers (splitting up text into single parts that are the building blocks for the data collection for the classification). The plugin uses the FisherClassifierImpl as the default classifier and the SimpleWordLister as the default word lister.

Installation

grails install-plugin bayes

Usage

class MyController {
  def bayesClassifierService
  /**
   * Trains 'someText' to be of 'someCategory'
   */ 
  def train = {
    bayesClassifierService.train(params.someText, params.someCategory)
  }
  /**
   * Determine the classification of 'someText'
   */
  def classifyText = {
    def classification = bayesClassifierService.classifyText(params.someText)
    ['classification':classification]
  }
}
