Abstract

While social media has been proved as an exceptionally useful tool to interact with other people and massively and quickly spread helpful information, its great potential has been ill-intentionally leveraged as well to distort political elections and manipulate constituents. In the paper at hand, we analyzed the presence and behavior of political social bots on Twitter in the context of the November 2019 Spanish general election. Throughout our study, we classified involved users as Social bots or humans, and examined their interactions from a quantitative (i.e., amount of traffic generated and existing relations) and qualitative (i.e., user's political affinity and sentiment towards the most important parties) perspectives. Results demonstrated that a non-negligible amount of those bots actively participated in the election, supporting each of the five principal political parties.

Usage

There are five notebooks to perform the analysis of the data. To be precise:

Phase 1 takes care of importing, checking, completing, and formatting the raw data retrieved from the Social Feed Manager [5].
Phase 2 preprocess the data in order to calculate the required features. It also anonymizes the data for the analysis.
Phase 3 extracts the statistical information regarding the social bots' activities.
Phase 4 processes the data for the social bots' classification, which is performed with Orange3 [6]. The friendship graph is drawn with Gephi [7].
Phase 5 performs the analysis of the results provided by the social bots' classification process.
