Mexican Political Twitter Dataset (2018 Presidential Election)

This dataset contains Twitter data collected during the 2018 Mexican presidential election campaign, focusing on mentions and tweets related to the main presidential candidates (@JoseAMeadeK, @RicardoAnayaC, @lopezobrador_, and @JaimeRdzNL). It represents a sample of 10,000 tweets from a larger dataset gathered as part of the research project "In-Context Learning for Misinformation Detection: Detecting Political Propaganda on Twitter Mexico using Large Language Model Meta AI".

The dataset includes the following fields:
tweet_id: Unique identifier for each tweet
followers_count: Number of followers of the user who posted the tweet
created_at: Original timestamp of tweet creation (UTC)
local_time: Timestamp converted to Mexico City time zone
tweet: Text content of the tweet
source: Platform or application used to post the tweet

This sample dataset was collected using the Twitter's streaming API in 2018. The script filtered the global Twitter stream for mentions of Mexico's presidential candidates.

Several fields present in the original data collection have been removed from this sample to comply with Twitter's terms of service and to protect user privacy:

Username (screen_name)
Tweet URL
Geographical coordinates
User location information

Only publicly accessible tweets (those without privacy restrictions set by users) were collected in the original dataset.

This dataset serves as a sample to provide insights into the larger research project focusing on misinformation detection and political propaganda analysis in Mexican social media during the 2018 presidential campaign. The research applies large language models to detect patterns of misinformation in political discourse.
