Modality Effects When Simulating User Querying Tasks

Abstract

When faced with an information need, different users are likely to issue different queries. A renewed interest in these user query variations has resulted in a number of collections, tasks, and studies which utilize multiple queries for each topic. The most commonly applied technique for generating query variations is to show a short backstory to a pool of crowdworkers, and ask each of them to provide a keyword query that they would expect to provide more information pertaining to the backstory.
