## Class KEAModelBuilder

    java.lang.Object
      |
      +--KEAModelBuilder

All Implemented Interfaces:
  weka.core.OptionHandler

public class KEAModelBuilder
extends java.lang.Object
implements weka.core.OptionHandler

Builds a keyphrase extraction model from the documents in a given directory. Assumes that the file names for the documents end with ".txt". Assumes that files containing corresponding author-assigned keyphrases end with ".key". Optionally an encoding for the documents/keyphrases can be defined (e.g. for Chinese text). Valid options are:

-l "directory name"
Specifies name of directory.

-m "model name"
Specifies name of model.

-e "encoding"
Specifies encoding.

-d
Turns debugging mode on.

-k
Use keyphrase frequency statistic.

-p
Disallow internal periods.

-x "length"
Sets maximum phrase length (default: 3).

-y "length"
Sets minimum phrase length (default: 1).

-o "number"
The minimum number of times a phrase needs to occur (default: 2).

-s "name of class implementing list of stop words"
Sets list of stop words to used (default: StopwordsEnglish).

-t "name of class implementing stemmer"
Sets stemmer to use (default: IteratedLovinsStemmer).

-n
Do not check for proper nouns.
