In the results of a RELWORD job, you'll find a list of seed words/concepts that are relevant to the inputs you provided.
As you can see, the results provide you with a quick overview of words that comprise your theme. Some of them, you have probably covered on your own, but others you might have missed. And this is where KTT comes in handy.
These are called seed words. They act as initial words from which you can build relevant phrases.
In this example, I decided to start mining the concept "plumbing", which is definitely relevant to home improvement.
