Introduction

The 2020 US Elections was held on November 2020. We visualize the discourse on social media before and after the elections, related to the theme of voter fraud. After the elections, on 6th January 2021, there was an insurrection at the Capitol in Washington DC. Protesters claimed voter fraud and that the wrong president was voted in. We visualize the discourse on social media before and after this insurrection event. Specifically, we looked at the changes in emotions, sentiment and other psycholinguistic cues during these few weeks. We also looked at the geographical distribution of these items across states in the United States. We visualize three social media platforms: Twitter, Reddit and Facebook.

Goals of the project

This data visualization aims to explore the following:

  1. What is the general trend, emotions and sentiment displayed in the social media data regarding voter fraud before/after the election?
  2. What is the general trend, emotions and sentiment displayed in the social media data regarding voter fraud before/after the insurrection?
  3. How do the general trend, emotions and sentiment displayed in the social media data differ across states?
  4. How do the general trend, emotions and sentiment displayed in the social media data differ across social media platforms?

Data

Collection Methodology

In this project we explore several datasets spanning three social media and two events. These data are collected along the theme of voter fraud. The timeframe for election collection was: (a) before election: October 27 to November 2 2020; (b) after election: November 3 to November 9 2020. The time frame for insurrection collection was: (a) before insurrection: Dec 30 to Jan 5; (b) after insurrection: Jan 6 to Jan 12.

Twitter data was collected using the Twitter V1 API. Facebook data was collected with CrowdTangle. Reddit data was collected with PSAW.

The list of hashtags used in the collection includes: #corruptelection, #deadvoters, #deceasedvoters, #dominionvotingsystems, #electionfraud, #electionintegrity, #fakeelection, #fakevotes, #fraudulentelection, #legalvotesonly, #legitimatevotesonly, #massivecorruption, #riggedelection, #stolenelection, #trumpismypresident, #voterfraud.

After this, we also further rehydrate the Twitter data using the Python Twarc library to obtain the full tweets with geolocation information.

The data can be accessed from Google Drive

Applying Machine Learning

We look to apply machine learning to the dataset by further annotating the data with emotions. We first train an emotion classifier on a tweet dataset that was already annotated. This is the SemEval-2018 Task 1: Affect in Tweets dataset. We create a classifier using a BiLSTM and a Convolutional Neural Network. Our classifier performs with 74.8% accuracy. Then we apply this classifier to annotate each of the text with a probability of each of the following emotions: disgust, anger, fear, joy and sadness.

We further annotate the data with sentiments and psycholinguistic cues, which was done using the Linguistic Inquiry and Word Count engine. This engine returns normalized probabilities of each item, eg. positive sentiment, negative sentiment, expression of family.

Data Preprocessing

After receiving the data, we performed data processing to clean the data in order to be able to better visualize it as well as for the practical reason of making the interactive process run in a quick manner. We removed all items with missing emotions and sentiments from the data. We also removed items with the same repeated texts, eg retweets. We created new columns tagging the prevailing sentiment and emotion of each text by processing sentiment and emotion measures of each text in the dataset and take the emotion or sentiment which is highest in value as the tag. As mentioned before we also rehydrate the data for additional information. We then process the rehydrated data so it would be compatible to a known US state map visualization library.

Approach

We will attempt to tell a compelling story about the trends, emotions and sentiments across the two events. Users can switch focus between each event and will be helped by narrations to make sense of differences between the two events, time and social media sources in the whole discourse. To give this contrast, we will divide the page into three main section - An introduction and overview section, one section to see trends in discourse (topic, top posting accounts, geolocation) and one regarding sentiments and emotions for the user to discern the change of emotions from before to after the events. Initial design can be seen [here](Design of Interactive Data Science Project.pdf) For the overview, we present the general statistics of the data set by way of big number 'metric' chart, accompanied by a line chart to show growth/decline of tweet/post activity around the topic for the observed social medias over the observation window. The trends in discourse section will show top terms and top posting accounts through bar chart as a means of rank comparison. We also added an interactive US state map that show the concentration of posts around this topic. The emotions section are filled with stacked bar chart to show shares of sentiment and emotion over time, and a bar chart for general comparison. We also used box plot to visualize emotion intensity over time.

Exploratory Data Analysis

Before showing the interactive visualization, we did a round of exploratory data analysis to get a sense of the data. The EDA for the election part of the data can be seen here, meanwhile the EDA for the insurrection part of the data can be seen here

Team member contributions

All team members contributed equally to this project. Lynnette did the initial data collection and processing, Adya did exploratory data analysis for the insurrection and Kevin did exploratory data analysis for the elections. All members contributed to the development of the interactive data dashboard and the recording of the video.
