Abstract
A system identifies a set of documents from a corpus of documents that are relevant to a word, phrase or sentence and that were published at approximately a same time period, where each document of the set of documents includes news content and has an associated headline. The system extracts headlines from the set of documents and derives a score for each headline of the extracted headlines based on how many times selected words in each headline occurs among all of the extracted headlines.
