Extracting Data from Twitter using Python

Welcome to Week 8 of ArcGIS Hub’s Civic Analytics Notebook series. In the last post we saw how the data catalog of a Hub can be analyzed and visualized. A data catalog is an organized collection or inventory of all the data assets in your Hub and their metadata, that aims to improve data transparency, access and governance.

This week we look at ways to extract data from social media platforms like Twitter. Over the years, Twitter has proved to be a gold mine for learning about events happening in real time and the social reach and impact of those events. Most people tweet about their opinion or experience regarding an event by tagging and mentioning relevant twitter handles (accounts) or by using hashtags that categorize their tweet and helps users find content related to the hashtag or topic. This data can be used for research as well as to obtain civic and demographic insights. Accessing publicly available tweets for our city or local region helps invert our lens and understand the general public and what matters to them.

We use the tweepy Python library here to access the Twitter API and fetch tweets. Before we get started with scripting using tweepy, you will need to apply for a Twitter developer account to access their API. Once your application is approved, you will have access to a few consumer and access keys that are used to authenticate you before allowing you to work with the Twitter API. Here is a great tutorial by Twitter that covers the steps for applying for a developer account. Once we have our developer credentials, we are ready to get started with the notebook.

Few different scenarios for extracting tweets

In this notebook we introduce 5 different scenarios of filtering and extracting tweets.

I invite you to experiment with the different Twitter data extraction techniques in this notebook. Leverage the power of this data by creating ArcGIS Dashboards, Experience Builder, Insights apps that can provide a visual summary of the trends and sentiments from this data. Here is an example of an ArcGIS Dashboard we created with this data. Next week we will see how to extract and analyze tweets from our city to understand the social fabric of our city or local region using text and spatial analysis techniques. We are looking forward to hearing your thoughts and experience with this notebook and our other Civic Analytics notebook offerings on our Community thread.
