Start by reading the tutorial for this repo: Sentiment Analysis of Reddit AMAs which explains how to use Apache Spark, Cloudant, and Watson Tone Analyzer to perform sentiment analysis on a reddit Ask Me Anything web event.
Then move on to the follow-up tutorial Sentiment Analysis of Reddit AMAs using dashDB and R, which shows an alternate output. Move Cloudant JSON data on to a dashDB warehouse, then use built-in analysis tool R to glean meaning and insights.
Interested in SparkR? Read the third tutorial in this series, which shows how to connect to Cloudant via CouchDB then analyze the JSON with SparkR.
