The various steps are as follows: * Setting up an Azure WebJob to collect Twitter data based on user specified keywords. * Pumping ingested tweets into Azure Event Hub which can accept millions of events per second. * Processing incoming tweets with an Azure Stream Analytics job that stores the raw data in Azure Blob Storage and Azure SQL Database. * The Stream Analytics job calls an Azure Machine Learning web service to determine the sentiment of each tweet. * Visualizing real-time metrics about inferred sentiment using Time Series Insights for Operational Technology real-time monitoring and Power BI for Information Technology reporting and analysis. ## Prerequisites To run the TwitterClient web job, you will need: 1. A [Twitter account](https://twitter.com/login) 2. A [Twitter application](https://apps.twitter.com) 3. Twitter's Streaming API OAuth credentials - On the Twitter application page, click on the *Keys and Access Tokens* tab - *Consumer Key (API Key)* and *Consumer Secret (API Secret)* can be found under **Application Settings** section - Under **Your Access Token** section, click on *Create my access token* to obtain both *Access Token* and *Access Token Secret* More details on Twitter's Streaming API OAuth access token can be found [here](https://dev.twitter.com/oauth/overview/application-owner-access-tokens). ## Disclaimer ©2017 Microsoft Corporation.
