People used social media to organize demonstrations (both pro- and anti-governmental), disseminate information about their activities, and raise local and global awareness of ongoing events

## Our Objective
|
||
|
|
|
||
|
|
Quantify and present data on two italian politicians, **Matteo Renzi** and **Matteo Salvini** as a first step towards an appropriate study of the behaviour of influencial politicians online.

## Dataset
|
||
|
|
|
||
|
|
Our dataset consisted in 5370 posts by Matteo Renzi and Matteo Salvini publicly accessible on Facebook.
|
||
|
|
|
||
|
|
The dataset was obtained by scraping using [python requests](https://2.python-requests.org/en/master/).

|
## Main Difficulties
|
||
|
|
|
||
|
|
Scraping Facebook is a hard task if you can't request API keys.
|
||
|
|
|
||
|
|
* We got banned various times
|
||
|
|
* Page elements related to likes, interactions and responding users always change `id` and `class`
|
||
|
|
|
||
|
|
For these reasons we limited the analysis to just two politicians.

## Future improvements
|
||
|
|
|
||
|
|
Consider that a post could provide different values such as:
|
||
|
|
* increase partecipation
|
||
|
|
* provide information
|
||
|
|
* grab or detract attention

||

|
## Future improvements
|
||
|
|
|
||
|
|
Focus on semantic analysis:
|
||
|
|
|
||
|
|
* geographical data
|
||
|
|
* number of likes, shares
|
||
|
|
* rate of engagement
|
||
|
|
* sentiment analysis
|
||
|
|
* fake news detection
|
||
|

|
## Network Perspective
|
||
|
|
|
||
|
|
Model the analysis from an ego network:
|
||
|
|
|
||
|
|
* profiles of people following a politician
|
||
|
|
* spread of relevant/fake information
|
||
|
|
* model engagement and cascading behaviour with other users
|
||
|
|
* model social influence
|
||
|
|
* understand esternalities on a macro scale
