You can just input your keywords, and dont have to worry about the programming part.

Besides the information which can be retrieved via the free twitterscraper tool, the website also retrieves user information.

Synopsis

A simple script to scrape for Tweets using the Python package requests to retrieve the content and Beautifullsoup4 to parse the retrieved content.

1. Motivation

Twitter has provided REST API's which can be used by developers to access and read Twitter data. They have also provided a Streaming API which can be used to access Twitter Data in real-time.

Most of the software written to access Twitter data provide a library which functions as a wrapper around Twitters Search and Streaming API's and therefore are limited by the limitations of the API's.

With Twitter's Search API you can only sent 180 Requests every 15 minutes. With a maximum number of 100 tweets per Request this means you can mine for 4 x 180 x 100 = 72.000 tweets per hour. By using TwitterScraper you are not limited by this number but by your internet speed/bandwith and the number of instances of TwitterScraper you are willing to start.

One of the bigger disadvantages of the Search API is that you can only access Tweets written in the past 7 days. This is a major bottleneck for anyone looking for older past data to make a model from. With TwitterScraper there is no such limitation.

Per Tweet it scrapes the following information: + Username and Full Name + Tweet-id + Tweet-url + Tweet text + Tweet html + Tweet timestamp + No. of likes + No. of replies + No. of retweets

2. Installation and Usage

To install twitterscraper:

(sudo) pip install twitterscraper

or you can clone the repository and in the folder containing setup.py

python setup.py install

2.2 The CLI

You can use the command line application to get your tweets stored to JSON right away. Twitterscraper takes several arguments:

• -h or --help Print out the help message and exits.

• -l or --limit TwitterScraper stops scraping when at least the number of tweets indicated with --limit is scraped. Since tweets are retrieved in batches of 20, this will always be a multiple of 20.

  Omit the limit to retrieve all tweets. You can at any time abort the scraping by pressing Ctrl+C, the scraped tweets will be stored safely in your JSON file.

• --lang Retrieves tweets written in a specific language. Currently 30+ languages are supported. For a full list of the languages print out the help message.

• -bd or --begindate Set the date from which TwitterScraper should start scraping for your query. Format is YYYY-MM-DD. The default value is set to 2006-03-21.

• -ed or --enddate Set the enddate which TwitterScraper should use to stop scraping for your query. Format is YYYY-MM-DD. The default value is set to today.

• -p or --poolsize Set the number of parallel processes TwitterScraper should initiate while scraping for your query. Default value is set to 20. Depending on the computational power you have, you can increase this number. It is advised to keep this number below the number of days you are scraping. For example, if you are scraping from 2017-01-10 to 2017-01-20, you can set this number to a maximum of 10. If you are scraping from 2016-01-01 to 2016-12-31, you can increase this number to a maximum of 150, if you have the computational resources.

• -o or --output Gives the name of the output file. If no output filename is given, the default filename 'tweets.json' or 'tweets.csv' will be used.

• -c or --csv Write the result to a CSV file instead of a JSON file.

• -d or --dump: With this argument, the scraped tweets will be printed to the screen instead of an outputfile. If you are using this argument, the --output argument doe not need to be used.

2.2.1 Examples of simple queries

Below is an example of how twitterscraper can be used:

twitterscraper Trump --limit 100 --output=tweets.json

twitterscraper Trump -l 100 -o tweets.json

twitterscraper Trump -l 100 -bd 2017-01-01 -ed 2017-06-01 -o tweets.json

2.2.2 Examples of advanced queries

You can use any advanced query Twitter supports. An advanced query should be placed within quotes, so that twitterscraper can recognize it as one single query.

Here are some examples:

• search for the occurence of 'Bitcoin' or 'BTC': twitterscraper "Bitcoin OR BTC " -o bitcoin_tweets.json -l 1000
• search for the occurence of 'Bitcoin' and 'BTC': twitterscraper "Bitcoin AND BTC " -o bitcoin_tweets.json -l 1000
• search for tweets from a specific user: twitterscraper "Blockchain from:VitalikButerin" -o blockchain_tweets.json -l 1000
• search for tweets to a specific user: twitterscraper "Blockchain to:VitalikButerin" -o blockchain_tweets.json -l 1000
• search for tweets written from a location: twitterscraper "Blockchain near:Seattle within:15mi" -o blockchain_tweets.json -l 1000

2.3 From within Python

You can easily use TwitterScraper from within python:

from twitterscraper import query_tweets

if __name__ == '__main__':
    list_of_tweets = query_tweets("Trump OR Clinton", 10)

    #print the retrieved tweets to the screen:
    for tweet in query_tweets("Trump OR Clinton", 10):
        print(tweet)

    #Or save the retrieved tweets to file:
    file = open(“output.txt”,”w”)
    for tweet in query_tweets("Trump OR Clinton", 10):
        file.write(tweet.encode('utf-8'))
    file.close()

3. Output

All of the retrieved Tweets are stored in the indicated output file. The contents of the output file will look like:

[{"fullname": "Rupert Meehl", "id": "892397793071050752", "likes": "1", "replies": "0", "retweets": "0", "text": "Latest: Trump now at lowest Approval and highest Disapproval ratings yet. Oh, we're winning bigly here ...\n\nhttps://projects.fivethirtyeight.com/trump-approval-ratings/?ex_cid=rrpromo\u00a0\u2026", "timestamp": "2017-08-01T14:53:08", "user": "Rupert_Meehl"}, {"fullname": "Barry Shapiro", "id": "892397794375327744", "likes": "0", "replies": "0", "retweets": "0", "text": "A former GOP Rep quoted this line, which pretty much sums up Donald Trump. https://twitter.com/davidfrum/status/863017301595107329\u00a0\u2026", "timestamp": "2017-08-01T14:53:08", "user": "barryshap"}, (...)
]

3.1 Opening the output file

In order to correctly handle all possible characters in the tweets (think of Japanese or Arabic characters), the output is saved as utf-8 encoded bytes. That is why you could see text like "u30b1 u30f3 u3055 u307e u30fe ..." in the output file.

What you should do is open the file with the proper encoding:

Example of output with Japanese characters

TO DO

• Twitterscraper can not retrieve retweets.
• Add caching potentially? Would be nice to be able to resume scraping if something goes wrong and have half of the data of a request cached or so.
