Keywords, which we define as a sequence of one or more words, provide a
compact representation of a document’s content. Ideally, keywords represent in
condensed form the essential content of a document. Keywords are widely used
to define queries within information retrieval (IR) systems as they are easy to
define, revise, remember, and share. In comparison to mathematical signatures,
keywords are independent of any corpus and can be applied across multiple
corpora and IR systems
