download-tweets-ai-text-gen-plus

A small Python 3 script to download public Tweets from Twitter accounts into a format suitable for AI text generation tools (such as gpt-2-simple for finetuning GPT-2).

Retrieves all tweets as a simple CSV with a single CLI command
Preprocesses tweets to remove URLs, extra spaces, and optionally usertags/hashtags
Saves tweets after each collection in case there is an error or you want to end collection early

You can view examples of AI-generated tweets from datasets retrieved with this tool in the /examples folder.

Setup

First, clone this repository onto your system and install dependencies with the following commands:

git clone https://github.com/sdelgadoc/download-tweets-ai-text-gen-plus.git
cd download-tweets-ai-text-gen-plus
pip3 install -r requirements.txt

Previous versions of this code used scraping libraries to collect tweets. Since then, Twitter has made scraping harder while providing more robust tweet collection API's. In response, we ported this code to run only with the Twitter's API.

To continue the setup, create a Twitter app so you can obtain access to the Twitter API. Once you create an app, generate access tokens, and input them into the section of the keys.py file shown below.

keys = {'consumer_key': "",
        'consumer_secret': "",
        'access_token': "",
        'access_token_secret': ""}

Finally, go to the Twitter API's Dev environments page, generate a Dev environment for the Full Archive API, and input the environment's name into the section of the keys.py file shown below.

environment_name = ""

Usage

The script is run via a command line interface. After cding into the directory where the script is stored in a terminal, run:

python3 download_tweets.py <twitter_username> 100

e.g. If you want to download 100 tweets (sans retweets/replies/quote tweets) from Twitter user @santiagodc, run:

python3 download_tweets.py santiagodc 100

NOTE: The Twittter API's free tier has a collection limit of 5,000 tweets per month, so set a tweet limit to avoid hitting your limit too quickly

The script can can also download tweets from multiple usernames at one time. To do so, first create a text file (.txt) with the list of usernames. Then, run script referencing the file name:

python3 download_tweets.py <twitter_usernames_file_name> 100

The tweets will be downloaded to a single-column CSV titled <usernames>_tweets.csv.

The parameters you can pass to the command line interface (positionally or explicitly) are:

username: Username of the account whose tweets or .txt file name with multiple usernames you want to download [required]
limit: Number of tweets to download [default: all tweets possible]
include_replies: Include replies from the user in the dataset [default: False]
strip_usertags: Strips out @ user tags in the tweet text [default: False]
strip_hashtags: Strips out # hashtags in the tweet text [default: False]
sentiment: Adds the specified number of sentiment categories to the output so you can then generate positive/negative tweets changing a parameter [default: 0, possible values: 0, 3, 5, 7]
text_format: Specifies the format in which tweets will be returned. The 'simple' format only returns the tweet text. The 'reply' format returns information on preceding tweets to train an AI that can reply to tweets [default: 'simple', possible values: 'simple', 'reply']

How does the sentiment functionality work

The sentiment parameter adds a sentiment category to the tweet text. This information allows the user to train and generate text with different sentiments by changing a parameter.

The output format using the 'simple' text format is the following:

[Sentiment category]
[Tweet text for the tweet that was collected]

The sentiment parameter accepts an integer that specifies the number of sentiment categories that are returned. The sentiment categories for the different possible parameters are the following:

0: No sentiment category is returned
3: POSITIVE, NEUTRAL, NEGATIVE
5: VERY POSITIVE, POSITIVE, NEUTRAL, NEGATIVE, VERY NEGATIVE
7: EXTREMELY POSITIVE, VERY POSITIVE, POSITIVE, NEUTRAL, NEGATIVE, VERY NEGATIVE, EXTREMELY NEGATIVE

How does the text_format functionality work

The code supports collecting tweets in a format for trainining an AI that can reply to other tweets. The output format is based on the format used to train the Subreddit Simulator Reddit community.

The output format is the following:

****ARGUMENTS
ORIGINAL or REPLY: Whether the tweet is an original tweet or a reply
SENTIMENT: If the sentiment parameter is used, text describing the tweet text's sentiment
****PARENT
[Tweet text for the topmost tweet in a reply thread]
****IN_REPLY_TO
[Tweet text for the tweet that is being responded to]
****TWEET
[Tweet text for the tweet that was collected]

To collect tweets with this reply format by running the following statement:

python3 download_tweets.py <twitter_username> None True False False False 3 reply

How to Train an AI on the downloaded tweets

gpt-2-simple has a special case for single-column CSVs, where it will automatically process the text for best training and generation. (i.e. by adding <|startoftext|> and <|endoftext|> to each tweet, allowing independent generation of tweets)

You can use this Colaboratory notebook (optimized from the original notebook for this use case) to train the model on your downloaded tweets, and generate massive amounts of Tweets from it. Note that without a lot of data, the model might easily overfit; you may want to train for fewer steps (e.g. 500).

When generating, you'll always need to include certain parameters to decode the tweets, e.g.:

gpt2.generate(sess,
              length=200,
              temperature=0.7,
              prefix='<|startoftext|>',
              truncate='<|endoftext|>',
              include_prefix=False
              )

Helpful Notes

You'll need thousands of tweets at minimum to feed to the input model for a good generation results. (ideally 1 MB of input text data, although with tweets that hard to achieve)
To help you reach the 1 MB of input text data, you can load data from multiple similar Twitter usernames
The download will likely end much earlier than the theoretical limit (inferred from the user profile) as the limit includes retweets/replies/whatever cache shennanigans Twitter is employing.
The legalities of distributing downloaded tweets is ambigious, therefore it's recommended avoiding commiting raw Twitter data to GitHub, and is the reason examples of such data is not included in this repo. (AI-generated tweets themselves likely fall under derivative work/parody protected by Fair Use)
