    ADDITIONAL INFORMATION
    I have used Natural Language Processing on review based texts to find insights…We found that when trying to identify issues or areas of concerns, we wrote queries to identify the Top 25 Negative Noun Tokens in Sentences and include the related sentences after Natural Language Processing. We then grouped those sentences for tagging in an interactive tree (tree of sentences). We were able to identify the top issues affecting consumers, very quickly; because of the refined sample size (Top 25 Tokens). We would repeat this effort with each week of new data…slowly becoming the knowledge experts in the source domain. As the unique issues started to dry up we instituted a dynamic filtering system where every keyword in a sentence became a filter. We could shuffle the results with each click, spinning the results. We also implemented the ability to combine those keywords and flip them for even more complex dynamic filters. And then we also started an automatic favourite keyword identification system so that on subsequent weeks of results, I knew which keywords/favs were able to pull back the targeted results we were after. So for those looking to find the top negative issues, this may be a plan of attack in the identification of issues, something you could include in your own system. I have incorporated these tools into http://text-analyzer.com to see this in action. Hope this helps someone when trying to identify the insights from customer feedback.
