Investigating the Relationship between Perceived Usefulness and Satisfaction with Query Reformulation Tools: The Viewpoints of Information Sciences Researchers

摘要

This study aims to study the relationship between perceived usefulness and satisfaction with query reformulation tools in the Science Direct Database. A descriptive analytic method was used to study the relationship between variables; the data were collected using a researcher-made questionnaire. The participants were selected among the students of Information Sciences in Islamic Azad University of Research and Science Center of Khuzestan (n = 28). The findings showed that users main reason for queryreformulation was not having enough time to investigate all retrieved results (Mean = 4.66). They also showed that based on perceived satisfaction and usefulness, the users used the query tools which bounded them to the topic (Mean = 3.92 for usefulnessand M = 3.83 for satisfaction). In addition, Pearson's correlation co-efficiency (r = 0.939) at (0.001) significance level showed that users perceived usefulness from query reformulation tools increased satisfaction. Perceiving the usefulness of query reformulation tools improves the use of results. However, the usefulness is not the same for all tools and needs to be reviewed.
