"Search vendors and niche software specialists offer components than can assign index terms not contained in a source document.

The advantage of systems that assign metatags via “smart software” or via a combination of automatic systems and human subject matter experts is sometimes called “discovery”. The idea is that the interface displays related information or suggests documents that may help the user answer a question. "

Leading companies in this field are Autonomy, Endeca, Vivisimo, Exalead, Google and Microsoft.

The book is available for download for only $20 - sounds like a bargain to me -- http://www.pandia.com/enterprise-search/
