The text classifiers in big data analytics is very useful for identifying words that are of interest to you, such as keywords or phrases (or even entire sentences).
It's not always perfect but it does make searching through large amounts easier than using traditional methods like grep/awk with regex patterns if your looking at thousands upon tens-of -thousands rows worths per file! I dislike how difficult this tool can be when trying out new features / models since there seems no way around learning everything about every single feature before actually being able use them without having some sorta "cheat sheet". Also sometimes training takes quite long time which makes things frustrating especially while working during off hours where my internet connection isn't great enough so i'm only allowed 15minutes here & 5 minuts overthere! But overall its still an amazing product compared other companies who charge 10x more just because they have fancy names instead saying what their doing right.
