Keyword suggests for query expansion in Google is a new facility. However, users may find it difficult to use. The aim of this research is to investigate the extent and the types of cognitive load (Extraneous, Intrinsic, and/or Germane) that the searchers encounter in using Google suggested keywords. Little research has been reported in the area of using suggested keywords in the process of query expansion. The methodology of this research helps access to valuable results in this regard. Design/Methodology/Approach: Through a mixed approach (using a questionnaire as well as “think aloud” technique) quantitative and qualitative data were collected from 60 post-graduate students from two broad fields of Humanities and Basic Sciences at Ferdowsi University of Mashhad, Iran. FindingsFindings show that suggested keywords and retrieved pages did not make any significant problem (or negative cognitive load) for users. Also, there was no significant difference between Humanities students and Basic Science students regarding cognitive load when they were browsing the suggested keywords. Most of the suggested keywords and retrieved pages could fulfill users’ needs and had direct relationship with their primary keywords. ConclusionsSuggested keywords/queries can help Web searchers learn better and expand their queries faster. On the other hand, based on users' reactions in this research towards the list of suggested keywords, designers could improve the search interface and provide a more relevant structure for optimizing queries.","PeriodicalId":249610,"journal":{"name":"Categories, Contexts and Relations in Knowledge Organization","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126280984","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Julien, Pierre Tirilly","doi":"10.5771/9783956504402-109","DOIUrl":"https://doi.org/10.5771/9783956504402-109","url":null,"abstract":"The Library of Congress Subject Headings (LCSH) is a subject structure used to index large collections throughout the world. Browsing a collection through LCSH is difficult using current on-line tools in part because they are inadequately integrated with information collections. Users of these LCSH browsing tools are expected to find a promising LCSH string before using it to search for the information itself; many users do not have the patience for such a two-step process. This article proposes a method to fully integrate a specific collection in its subset of the LCSH hierarchy in order to facilitate LCSH browsing as well as information retrieval. Techniques are described to match LCSH strings assigned to the collection with an established string from the authority records, and build their specific LCSH hierarchy. The resulting subset of LCSH structure is described in terms of its size and broader/narrower term statistics, and implications for browsing and information retrieval are discussed. The results of this research have implications for institutions wishing to further capitalize on existing LCSH organization investments for the purpose of subject browsing and information retrieval.","PeriodicalId":249610,"journal":{"name":"Categories, Contexts and Relations in Knowledge Organization","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115762107","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
