Sentence Boundary Detection (SBD)
==================

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

Installation

Use npm:

$ npm install sbd

How to

``javascript var tokenizer = require('sbd');

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 abbreviations.

* 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 abbreviations.
