Tokenizers

Last updated 8 months ago

Whitespace

"Dot space" redirects here. For the animated film, see ."␣" redirects here. It is not to be confused with .

In , is any or series of characters that represent horizontal or vertical in . When rendered, a whitespace character does not correspond to a visible mark, but typically does occupy an area on a page. For example, the common whitespace symbol U+0020 SPACE (also 32) represents a punctuation character in text, used as a in Western .

Wink-tokenizer

By default, Datasaur uses the to separate text into individual tokens, which are grouped by lines of sentences.

"Wink is a family of open source packages for Statistical Analysis, Natural Language Processing and Machine Learning in NodeJS." (source: )

How does it work? It works by using pattern matching via regular expressions (regex). The list of regexes used by wink-tokenizer can be seen in detail at . In summary, it will parse the following by default:

Name
Description

currency

such as $ or £ symbols (r)

email

for example john@acme.com or superman1@gmail.com (e)

emoji

any standard unicode emojis e.g. - ✅ or ❌ -> 1 UTF-16 unit - 😊 or 😂 or 🎉 -> 2 UTF-16 units - 🇮🇩 or 🇺🇸 -> 4 UTF-16 units (j)

emoticon

common emoticons such as :-) or :D (c)

hashtag

hash tags such as #happy or #followme (h)

number

any integer, decimal number, fractions such as 19, 2.718 or 1/4 and numerals containing ", - / .", for example 12-12-1924 (n)

ordinal

ordinals like 1st, 2nd, 3rd, 4th or 12th or 91st (o)

punctuation

common punctuation such as ? or , ( token becomes fingerprint )

quoted_phrase

any "quoted text" in the sentence. Note: its default value is false. (q)

symbol

for example ~ or + or & or % or / ( token becomes fingerprint )

time

common representation of time such as 4pm or 16:00 hours (t)

mention

@mention as in github or twitter (m)

url

word

word such as faster or résumé or prévenir (w)

Playground

URL such as (u)
