Study material for Data Exploration, Data Pre-Processing and Feature Engineering.

I came across some process or steps like Data Exploration, Data Pre-Processing and Feature Engineering. I searched so much on google for some good material which can help me to understand that concept and its steps or working but I didn't get any relevant material. Kindly suggest me some relevant material for practising.

these terms all are fancy names for looking at your unprocessed data in order to get an idea of the contents, identify key words (for example if I am looking for financial figures for 2016, I will look for the "feature" '2016'. If I find some sequences '2016' then I hope the data is worth processing in detail)

This process typically entails examination of "unstructured data" , and here is where Unix utilities like "grep" are outstanding. Java also have the tools for searching unstructured data.
