This project is a direct port of Pragmatic Segmenter which provides rule-based sentence boundary detection.


The Segmenter class provides the Segment method which in the simplest usage takes a string:

using PragmaticSegmenterNet;

IReadOnlyList<string> result = Segmenter.Segment("One Sentence. And another sentence.");

// ["One Sentence.", "And another sentence."]

IReadOnlyList<string> result2 = Segmenter.Segment("Anything.", Language.Italian);

// ["Anything"]

The Segment method has a number of optional parameters:

IReadOnlyList<string> Segment(string text, Language language = Language.English, bool cleanText = true, DocumentType documentType = DocumentType.Any)
  • Language - An enum representing the supported languages, the default is English, see the supported languages list below for the list of currently supported languages.
  • CleanText - A boolean indicating whether the input text should be cleaned prior to segmentation. Cleaning removes extra newlines and whitespace. Defaults to true.
  • DocumentType - Used by the text cleaning process to determine which reformatting to apply. For PDFs this handles newlines in the middle of a sentence whereas for HTML documents this will handle HMTL tags. Defaults to any which does not apply any special formatting.


  • English = 0 (default)
  • Amharic = 1
  • Arabic = 2
  • Armenian = 3
  • Bulgarian = 4
  • Burmese = 5
  • Chinese = 6
  • Danish = 7
  • Dutch = 8
  • French = 9
  • German = 10
  • Greek = 11
  • Hindi = 12
  • Italian = 13
  • Japanese = 14
  • Kazakh = 15 (partial support, potentially only for the Cyrillic form of the alphabet)
  • Persian = 16
  • Polish = 17
  • Russian = 18
  • Spanish = 19
  • Urdu = 20



  • Fixes an issue with non-breaking spaces in numbered lists


  • Fixes an issue with text containing regex replacement groups, e.g. $0, $1, etc.


  • Fixes an issue with periods following abbreviations.


  • Fixes an issue with single character inputs.


This project wouldn't be possible without the work done by Pragmatic Segmenter team. Any bugs in the code are entirely my fault.
