From keywords to keyqueries
Tim Gollub, Matthias Hagen, Maximilian Michel, Benno Stein · 2013
We introduce the concept of keyqueries as dynamic content descriptors for documents. Keyqueries are defined implicitly by the index and the retrieval model of a reference search engine: keyqueries for a document are the minimal queries that return the document in the top result ranks. Besides applications in the fields of information retrieval and data mining, keyqueries have the potential to form the basis of a dynamic classification system for future digital libraries---the modern version of keywords for content description.
