Answer 1

Datamining is the process of trying to find usefull information in big piles of raw data.

There are multiple approaches to it, and the Details will depend on what kind of information you’re looking for.

You can look for key-signatures that signify something is interesting to you, as a simple example you can look for file endings like .jpg when you’re searching for pictures.

Then there are some statistical analysis methods to find patterns (how likely is it that this text sequence a postal adress?)

And there are completely machine learning driven approaches where you make some computer program learn what the kind of data you are looking for looks like, and then it will point you towards everything that looks similar.
