{"pk":33399,"title":"Searching the World Wide Web Made Easy? The Cognitive Load Imposed by Query Refinement Mechanisms","subtitle":null,"abstract":"This article addresses the effectiveness of search reformulation using query refinement mechanisms on the Internet. Cognitive load was measured using a secondary digit-monitoring task. The load was found to be lower when using the refinement mechanisms than when perusing document summaries - suggesting that the development of refinement mechanisms can make Internet searching easier. Two refinement mechanisms, one based on statistical term co-occurrence and the other on a shallow natural language parsing technique were tested. No difference in load was found, possibly because of the limited time that subjects spent in the refinement process.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[],"section":"Short Papers","is_remote":true,"remote_url":"https://escholarship.org/uc/item/1fn3v9jq","frozenauthors":[{"first_name":"Simon","middle_name":"","last_name":"Dennis","name_suffix":"","institution":"School of Psychology; University of Queensland","department":""},{"first_name":"Robert","middle_name":"","last_name":"McArthur","name_suffix":"","institution":"School of Information Systems, Queensland University of Technology","department":""},{"first_name":"Peter","middle_name":"","last_name":"Bruza","name_suffix":"","institution":"School of Information Systems, Queensland University of Technology","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"1998-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/33399/galley/24458/download/"}]}
