LangExtract.Chunker (LangExtract v0.6.0)

Copy Markdown View Source

Splits text into sentence-level chunks using the Alignment.Tokenizer.

Sentence boundary rules:

  1. A :punctuation token of ., !, or ? ends a sentence, unless it forms a known abbreviation with the preceding word token.
  2. After sentence-ending punctuation, trailing closing punctuation (", ', ), ], }, », ”, ’) is consumed into the same sentence.
  3. A :whitespace token containing \n followed by an uppercase-starting :word token starts a new sentence.
