In this lab, you will use Amazon EMR to analyze Ngrams from Google Books. An n-gram is a contiguous sequence of n items from a given sequence of text or speech. For example, consider this sentence:
Some 2-grams from this sentence are "the sun", "in the" and "sets in". A sample 3-gram is "sets in the" and a sample 4-gram is "rises in the east".
N-grams are used to predict the probability of certain words appearing in a sequence. This can be useful for providing typing suggestions on web pages and mobile phones.
The steps in this lab are very similar to the activities that a Data Scientist would perform when analyzing a new set of data. This includes loading the data, examining the data attributes and writing SQL to analyze the data. You will run SQL against publicly available Ngrams data stored in Amazon S3 to gain interesting insights.
After completing this lab, you will be able to:
- Create an Amazon EMR cluster running Hive
- Use Hive statements to create tables from Google Ngram input data stored in Amazon S3
- Run Hive queries to drill-down and analyze data
- At the top of your screen, launch your lab by clicking
This will start the process of provisioning your lab resources. An estimated amount of time to provision your lab resources will be displayed. You must wait for your resources to be provisioned before continuing.
If you are prompted for a token, use the one distributed to you (or credits you have purchased).
- Open your lab by clicking
This will automatically log you into the AWS Management Console.
Please do not change the Region unless instructed.
