Peer reviewedSu, Louise T. – Journal of the American Society for Information Science and Technology, 2003
Presents an application of a model of user evaluation of four major Web search engines (Alta Vista, Excite, Infoseek, and Lycos) by undergraduates. Evaluation was based on 16 performance measures representing five evaluation criteria-relevance, efficiency, utility, user satisfaction, and connectivity. Content analysis of verbal data identified a…
