# Social Network Analysis of Twitter Topic-Network Structures during the 2019 European Elections
 
This study explores how **Twitter** users differently interact based on the topic of discussion in online conversations.
We examine how node-level **network topology measures** may affect the likelihood of interaction and the extent to which two nodes interact in distinct topic-network structures. We collect 21 million sampled tweets via the Twitter API, tracking more than 700 keywords during the 2019 European Elections. We perform our analysis on a final data set of 2,259,717 tweets on five politics-related topics: `brexit`, `populism`, `refugees`, `terrorism`, and `unemployment`.
A more in-depth explanation of our methodology can be found in Section 3 of this paper. In the *releases* tab you can find a **[pre-compiled PDF version](https://github.com/andreantonacci/eu2019/releases/tag/paper-v1.0)** of the paper, as well as the source code needed for reproduction.
## Project Structure
This project is structured in five sequential stages.
1. ```code/data_collection```: First, primary data is collected in real-time via the **Twitter real-time filter API** endpoints, then stored on a **MongoDB** (NoSQL) database for real-time querying and visualization, as well as on an **Amazon Web Services (AWS) S3** bucket for long-term storage.
> Check out **[Electionstats](https://electionstats.eu/)**, our side project and dashboard to visualize Twitter data at the aggregate level in real-time during the EU 2019 Election.
2. ```code/data_prep```: Secondly, data is cleaned, selected, and prepared with a five-step pipeline in **Python**. These scripts transform the raw data set into nodes and edges tables for each analyzed topic.
3. ```plots```: Then, the latter tables are imported to **[Gephi 0.9.2](https://gephi.org/)** in order to visualize their graph structures and compute network measurements.
4. ```code/data_analysis```: Subsequently, we import into an **R** program the updated tables with new measures exported from Gephi. This R script constructs adjacency lists and runs three generalized linear models for each topic, where the covariates are node-level network metrics. First, we run a multiple regression model on the number of interactions for every pair of users. Secondly, a logistic model to assess the probability of interaction between two users. Finally, a conditional (filtered) multiple regression model on the number of interactions, only for those pairs of users that interacted with each other.
5. ```paper```: Lastly, we write a paper in **LaTeX**.

## Requirements
#### Data Collection
* A Twitter Developer account with access to API
* An always-on machine (AWS EC2)
* Python 3.5+
* An S3 bucket on AWS
* [AWS CLI](https://aws.amazon.com/cli/) correctly configured
* [SnakeTail](http://snakenest.com/snaketail/) for logging (optional)
Use the package manager [pip](https://pip.pypa.io/en/stable/) to install [Tweepy](https://www.tweepy.org/):
```bash
pip install tweepy
```
#### Data Preparation
* Python 3.5+
* [Gephi 0.9.2](https://gephi.org/)
Use the package manager [pip](https://pip.pypa.io/en/stable/) to install the following libraries:
```bash
pip install pandas numpy pathlib boto3
```
#### Data Analysis
* R ([RStudio](https://rstudio.com/) is strongly suggested)
Use ```install.packages()``` to install the following:
```bash
tidyverse
modelr
broom
bit64
data.table
stargazer
censReg
car
ggpubr
Hmisc
corrplot
```
## Usage
Automated execution is available for the data preparation pipeline only (as shown on the right):
1. **[Download files](https://github.com/andreantonacci/eu2019/releases/tag/v1.0)** from the *releases* tab in one directory.
2. Then, simply run ```initialize.py```.
