Politic Bots

Politic Bots is a side-project that started within the research project ParticipaPY of the Catholic University "Nuestra Señora de la Asunción", which aims at designing and implementing solutions to generate spaces of civic participation through technology.

Motivated by the series of journalist investigations (e.g., How a Russian 'troll soldier' stirred anger after the Westminster attack, Anti-Vaxxers Are Using Twitter to Manipulate a Vaccine Bill, A Russian Facebook page organized a protest in Texas. A different Russian page launched the counterprotest, La oscura utilización de Facebook y Twitter como armas de manipulación política, How Bots Ruined Clicktivism) regarding the use of social media to manipulate the public opinion, specially in times of elections, we decided to study the use of Twitter during the presidential elections that took place in Paraguay in December 2017 (primary) and April 2018 (general).

To understand how the public and the political candidates use Twitter, we collected tweets published through the accounts of the candidates or containing hashtags used in the campaigns. This information was recorded in a CSV file that was provided to the tweet collector. The source code of the collector is available at here and the CSV file used to pull data from Twitter during the primaries can be found here.

Data Augmentation

The accounts and hashtags employed to collect tweets during the primary elections were augmented with information about the parties and internal movements of the candidates. A similar approach was followed to collect tweets for the general election. However, in this case, the hashtags and accounts were supplemented with information not only of the candidate parties but also about the region of the candidates, the name of their coalitions (if any), and the political positions that they stand for. The CSV file used to collect tweets during the general elections can be found here.

The functions create_flags and add_values_to_flags that annotate the tweets with information of the candidate's party and movement are implemented in the module add_flags.py in src/tweet_collector.

Data Cleaning

Some of the hashtags used by the candidates were generic Spanish words employed in other contexts and Spanish-speaking countries (e.g., a marketing campaign in Argentina) so, before starting any analysis, we had to ensure that the collected tweets were actually related to the elections in Paraguay. We labeled the collected tweets as relevant if they mention candidate accounts or if they had at least more than one of the hashtags of interest. The class TweetEvaluator in src/utils/data_wrangler.py contains the code that labels the collected tweets as relevant or not for this project.

Analyses

The directory reports contains the analyses conducted to study the use of Twitter during the primary and general elections. Jupyter notebook was employed to document the analyses and report the results. HTML files were generated to facilitate the access to the analyses and results.

Getting Started

Installation guide

Links to packages are provided below.

  1. Download and install Python >= 3.4.4;
  2. Download and install MongoDB community version;
  3. Create a Twitter APP by following the instructions here;
  4. Clone the repository git clone https://github.com/ParticipaPY/politic-bots.git;
  5. Get into the directory of the repository cd politic-bots;
  6. Create a virtual environment by running virtualenv env;
  7. Activate the virtual environment by executing source env/bin/activate;
  8. Inside the directory of the repository install the project dependencies by running pip install -r requirements.txt;

Optional for social network analysis: Download and install Gephi

Run

There are some tasks that can be run from src/run.py. Bellow we explain each of them.

Pre-requirements

  1. Set in src/config.json the information of the MongoDB database that is used to store the tweets;
  2. Activate the virtual environment by executing source env/bin/activate.

Collect Political Tweets

The data sets of tweets collected during the presidential primary and general elections that took place in Paraguay in December 2017 and April 2018, respectively, are available to be download.

In case a new set of tweets needs to be downloaded, below we list the steps that are required to follow.

  1. Create a CSV file to contain the name of the Twitter accounts and hashtags of interest. The CSV file should have a column called keyword with the list of accounts and hashtags. Additional columns can be added to the CSV to complement the information about accounts and hashtags. An example of CSV file can be found here;
  2. Rename src/config.json.example to src/config.json;
  3. Set to metadata in src/config.json the path to the CSV file;
  4. Set to consumer_key and consumer_secret in src/config.json the information of the authentication tokens of the Twitter App created during the installation process;
  5. Go to the src directory and execute python run.py --collect_tweets.

Depending on the number of hashtags and accounts the collection can take several hours or even days.

Create database of tweet authors

Before conducting analyses on the tweets, a database of the authors of tweets should be created. To create the database of users active the virtual environment source env/bin/activate and execute from the src directory python run.py --db_users. A new MongoDB database so called users is created as a result of this process.

Analyze the sentiment of tweets

It is possible to analyze the tone of tweets by executing, from the src directory, python run.py --sentiment_analysis. The sentiment of tweets are stored as part of the dictionary that contains the information of the tweet under the key sentimiento. We use the library CCA-Core to analyze the sentiment embed in Tweets. See here for more information about the CCA-Core library.

Identify relevant tweets

Tweets should be evaluated to analyze their relevance for this project. See Data Cleaning section to understand the problems with the hashtags used to collect tweets. From the src directory of the repository and after activating your virtual environment source env/bin/activate, run python run.py --flag_tweets to perform both tasks. The flag relevante, added to the dictionary that stores the information of the tweets, indicates whether the tweet is relevant or not for the purpose of this project.

Generate network of interactions

Once the database of users was generated a network that shows the interactions among them can be created for a follow-up social network analysis. From the src directory and after activating your virtual environment (source env/bin/activate), run python run.py --interaction_net to generate the network of interactions among the tweet authors. Examples of interaction networks can be found in the directory sna of the repo.

Troubleshooting

If you get the error ImportError: No module named when trying to execute the scripts, make sure to be at the src directory. If after being at the src directory you still get the same error, it is possible that you need to add the src directory to the PYTHONPATH by adding PYTHONPATH=../ at the beginning of the execution commands, e.g., PYTHONPATH=../ python analyzer/pre_analysis.py
