Extract Keyword Data from AWS Common Crawl Repository

We are looking for a person with experience in AWS EMR and the Common Crawl (CC) Data set on AWS. The person should be able to independently create an EMR job to extract keywords and count them on a URL page basis given a list of TLDs to search (or alternatively for all URLs in CC). The project has two parts: 1) Run a sample project to prove that cost won't be too high on a limited set of URLS, for example [login to view URL], [login to view URL], msnbc.com. 2) Generate output that allows us to lookup any full URL without parameters and retrieve a list of keywords for that page. The reverse should also be possible, search for a keyword with a threshold, and list all URL's where that keyword occurs more times than the specified threshold. The ability to perform these searches are included in the project. We do not need UI to perform the searches, a command line or AWS API call is acceptable, as long as the output can be saves in S3 buckets for each search.
