CRAN_Status_Badge R-CMD-check codecov Downloads Total Downloads GitHub last commit status DOI

Purpose

This package is focused on utilizing Twitter data due to its widespread global acceptance. The rapid expansion and acceptance of social media has opened doors into opinions and perceptions that were never as accessible as they are with today’s prevalence of mobile technology. Harvested Twitter data, analyzed for opinions and sentiment can provide powerful insight into a population. This insight can assist companies by letting them better understand their target population. The knowledge gained can also enable governments to better understand a population so they can make more informed decisions for that population. During the course of this research, data was acquired through the Public Twitter Application Programming Interface (API), to obtain Tweets as the foundation of data and will build a methodology utilizing a topic modeling and lexicographical approach to analyze the sentiment and opinions of text in English to determine a general sentiment such as positive or negative. The more people express themselves on social media, this application can be use1`d to gauge the general feeling of people.

Package

The saotd package is an R interface to the Twitter API and can be used to acquire Tweets based on user selected #hashtags and was developed utilizing a tidyverse approach. The package was designed to allow a user to conduct a complete analysis with the contained functions. The package will clean and tidy the Twitter data, determine the latent topics within the Tweets utilizing Latent Dirichlet Allocation (LDA), determine a sentiment score using the Bing lexicon dictionary and output visualizations.
