Java Number Normalizer (Beta)

• The main functionality of the Bar-Ilan University Normalizer is number normalization, i.e. a conversion from textual representations of numbers to a standard numerical string. For instance, "three thousand" is normalized to "3000" and "$134M" to "134000000 dollars" (see more examples below).
  
  The tool also includes:
  • String normalization: a simple string replacement per user-defined rules (e.g. "'ll" → "will").
  • Date & time normalization (e.g. "October 1, 2002" → "1/10/2002", ).
  Normalization may help (pre)processing tools such as parsers or coreference resolvers. This normalizer is being used in Bar-Ilan University's Textual Entailment engine (BiuTee) as a first preprocessing step, and has been used in a couple of additional works.
