Twitter Text Extraction

A fast screen name, hashtag, url extraction and tokenizer for tweets.

API

Chipper
  #users     => [Array]
  #hashtags  => [Array]
  #urls      => [Array]
  #tokens    => [Array]

  #skip_users
  #skip_hashtags
  #skip_tokens
  #skip_token_pattern

Usage

require 'chipper'

Chipper.skip_users(%w(youtube msn))
Chipper.skip_hashtags(%w(abc24 cnn))
Chipper.skip_tokens(%w(story tv why that get from your))
Chipper.skip_token_pattern '^vimeo$'

tweet = "hi @youtube, could we get #cnn videos so i can #watch it on my @apple tv http://t.co/HM7XoimM"
Chipper.users(tweet)    #=> ["@apple"]
Chipper.hashtags(tweet) #=> ["#watch"]
Chipper.urls(tweet)     #=> ["http://t.co/HM7XoimM"]

# n-gram tokenizer, returns a list of tokens partitioned by stop words, punctuation, urls and hashtags.
Chipper.tokens(tweet)   #=> [["could"], ["get"], ["videos"], ["can"]]

# single method that does all of the above and returns a hash.
Chipper.entities(tweet)
