1. Determine sentiment score and category
As demonstrated in the Big Data Analytics Workshop, use the Excel Azure Machine Learning Addon to
calculate sentiment value and sentiment category.
2. Use HDInsight to aggregate reviews
Develop an aggregate of these reviews using your knowledge of Hadoop and MapReduce in Microsoft
HDInsight.
a) Follow the same approach as the Big Data analytics workshop (using the wordcount method in
HDInsight) to determine the contributory words for each level of rating and sentiment category.
b) Present the workflow of using HDInsight (you may use screen captures) along with a summary of
findings for each level of rating and sentiment category. MapReduce documentation for HDInsight is
available here.
