Title

¬An experiment to test the utility of repeating phrases for information retrieval systems

Abstract

Describes a method of evaluating the utility of repeating phrases for information retrieval systems and calculating recall and precision. The technique compares 2 different techniques by asking people to perform tasks and then examining the outcomes of those tasks. Shows that people found those phrases automatically generated by finding repeating content words in documents to be good content indicators and discriminators were better than using words alone or phrases generated randomly from content words
