anti-phrasing
n.— «Wolfram Alpha works in the same way as Graffiti did: As Steven Wolfram says in his talk at the Berkman Center, people start out writing natural language but pretty quickly trim it down to just the key concepts (a process known in search technology circles as “anti-phrasing.”) In other words, by dint of patience and experimentation, we (or, at least, some of us) will learn to write queries in a notation that Wolfram Alpha understands, much like our hands learned Graffiti.» —“From links to seeds: Edging towards the semantic web” by Espen Andersen Applied Abstractions May 21, 2009.
