    Sentence Boundary Detection (SBD) Typescript

    Typescript version of popular library.

    Split text into sentences with a vanilla rule based approach (i.e working ~95% of the time).

    • Split a text based on period, question- and exclamation marks.
      • Skips (most) abbreviations (Mr., Mrs., PhD.)
      • Skips numbers/currency
      • Skips urls, websites, email addresses, phone nr.
      • Counts ellipsis and ?! as single punctuation

    Demo

    Installation

    Use npm or yarn:

    $ npm install sbd
    
    $ yarn add sbd
    

    How to

    var tokenizer = require('sbd');
    
    var optional_options = {};
    var text = "On Jan. 20, former Sen. Barack Obama became the 44th President of the U.S. Millions attended the Inauguration.";
    var sentences = tokenizer.sentences(text, optional_options);
    
    // [
    //  'On Jan. 20, former Sen. Barack Obama became the 44th President of the U.S.',
    //  'Millions attended the Inauguration.',
    // ]

    Optional options

    var options = {
        "newline_boundaries" : false,
        "html_boundaries"    : false,
        "sanitize"           : false,
        "allowed_tags"       : false,
        "preserve_whitespace" : false,
        "abbreviations"      : null
    };
    
    • newline_boundaries, force sentence split at newlines
    • html_boundaries, force sentence split at specific tags (br, and closing p, div, ul, ol)
    • sanitize: If you don't expect nor want html in your text.
    • allowed_tags: To sanitize html, the library santize-html is used. You can pass the allowed tags option.
    • preserve_whitespace: Preserve the literal whitespace between words and sentences (otherwise, internal spaces are normalized to a single space char, and inter-sentence whitespace is omitted). Preserve whitespace has no effect if either newline_boundaries or html_boundaries is specified.
    • abbreviations: list of abbreviations to override the original ones for use with other languages. Don't put dots in your custom abbreviations.
