Elegant and Easy Tweet Preprocessing in Python

Preprocessor

Preprocessor is a preprocessing library for tweet data written in Python.

When building Machine Learning systems based on tweet data, a preprocessing is required. This library makes it easy to clean, parse or tokenize the tweets.

Features

Currently supports cleaning, tokenizing and parsing:

• URLs
• Hashtags
• Mentions
• Reserved words (RT, FAV)
• Emojis
• Smileys

Supports Python 2.7 and 3.3+

Usage

Basic cleaning:

>>> import preprocessor as p
>>> p.clean('Preprocessor is #awesome 👍 https://github.com/s/preprocessor')
'Preprocessor is'

Tokenizing:

>>> p.tokenize('Preprocessor is #awesome 👍 https://github.com/s/preprocessor')
'Preprocessor is $HASHTAG$ $EMOJI$ $URL$'

Parsing:

>>> parsed_tweet = p.parse('Preprocessor is #awesome https://github.com/s/preprocessor')
<preprocessor.parse.ParseResult instance at 0x10f430758>
>>> parsed_tweet.urls
[(25:58) => https://github.com/s/preprocessor]
>>> parsed_tweet.urls[0].start_index
25
>>> parsed_tweet.urls[0].match
'https://github.com/s/preprocessor'
>>> parsed_tweet.urls[0].end_index
58

Fully customizable:

>>> p.set_options(p.OPT.URL, p.OPT.EMOJI)
>>> p.clean('Preprocessor is #awesome 👍 https://github.com/s/preprocessor')
'Preprocessor is #awesome'

Preprocessor will go through all of the options by default unless you specify some options.

Available Options:

Option Name	Option Short Code
URL	p.OPT.URL
Mention	p.OPT.MENTION
Hashtag	p.OPT.HASHTAG
Reserved Words	p.OPT.RESERVED
Emoji	p.OPT.EMOJI
Smiley	p.OPT.SMILEY
Number	p.OPT.NUMBER
