Cannot Train POS with Locale Other Than English

[schrieveslaach]

If I train the arktweet POS tagger with e.g. German locale (cf. train method), the training process fails because it generates a file containing decimals with German formatting. For example, numbers like 0.2 are formatted as 0,2 (German notation) and the trainer component fails to load this file because of the comma.

Hm. Maybe the locale has to be set as a java flag or property? Or it would be better to use non-locale-dependent, floating point number parsing code. I have no idea how to do that in java.

I agree to use a locale independent format. For example, you could write number in English format.

public class I18NTester {
   public static void main(String[] args) {
      String pattern = "###.##";
      double number = 123.45;

      Locale enlocale  = new Locale("en", "US");
   
      DecimalFormat decimalFormat = (DecimalFormat) NumberFormat.getNumberInstance(enlocale);
      decimalFormat.applyPattern(pattern);

      System.out.println(decimalFormat.format(number));
   
      }
}
