assessing the role of search, display, and guidance criteria on the user interface of federated search engine from the prspective of students in al-zahra university

purpose:the user interface of federated search engines is very important because it can make effective search, retrieval, and user interaction with the system. . identifying the most important indicators of the federated search engine user interface is a solution to enhance the applicability of the search engine interface. the purpose of this study was to examine the role of search, screen, navigating documents, retrieved results, consistency, guidance and navigation, and the error correction criteria on the user interface effectiveness of the federated search engines from the perspective of m.a / m.s.c students. methodology: the research method is survey in which the data collecting is done through a researcher-made questionnaire. this study measures the effectiveness of the model in the field of user interface to provide a federated search engine while testing the model as well. for the data analysis, the acceptability of the theoretical model was examined through lisrel software. to answer the research hypotheses, spss software was used to examine the relationship between the measures. findings:the results showed that the model can be used for the target population. according to the model, the characteristics of the user interface, the information display of the outward features, and the error correction of the structural features are more important than the other criteria.
