Abstract

Index terms are drawn from text documents without the need for language-specific processes or training and are suitable as gists for the subject documents. Index terms are extracted on the basis of scores of constituent n-grams relative to n-gram counts in a corpus. A method of extracting joint index terms to represent a plurality of documents is also provided.
