ReFactoring is the process by which longer, conversational pages and/or sets of pages that address the same issues are combined into fewer pages or a single page that is the digest of everything known on that topic. The editing and combining is done in a way that preserves the essential meaning of everything written there.
One simple form of this is that a page might begin as a list of questions and answers. These might be cleaned up by combining like questions, combining the answers and then dropping the questions. The result is a list of all that is known about the issue initially queried.
ReFactoring could also mean simplifing language without changing meaning. This is distinct from re-writing or re-working.
