tweet-preprocessor 0.6.0

Preprocessor

Preprocessor is a preprocessing library for tweet data written in Python. It was written as part of my bachelor thesis in sentiment analysis. Later I extracted it to a library for broader usage.

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

• JSON and .txt file support

Preprocessor v0.6.0 supports Python 2.7 and 3.5+ on Linux, macOS and Windows. Tests run on following setups:

Linux Xenial with Python 2.7, 3.5, 3.6, 3.7
macOS 10.14 with Python 3.7.5, 3.8.0
Windows 10.0.17134 with Python 2.7, 3.5.4, 3.6.8

Usage

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

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

>>> 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

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