Sentence Tagging

Detecting sentence boundaries is more complicated than it seems

sentence tagging


Ambiguous punctuation

Finding the end of a sentence is not always easy as punctuation can be used in numerous ways. For example, almost half of the periods in a typical news article are found in abbreviations rather than at sentence endings. A period may denote a number of things:

  • abbreviation (St. or Mr.)
  • decimal point ($4.34)
  • ellipsis (…)
  • email address (.com)
  • emoticon (o.O)
  • computer code (document.txt)
  • slang
  • phone numbers (123.456.7890)

Other commonly sentence-ending punctuation, such as question and exclamation marks, have their own exceptions as well. Rosette uses machine learning and statistical analysis to parse punctuation, utilizing context and language ambiguities to locate the sentence boundaries in a document, providing the groundwork for advanced text analysis in 40 languages.
