Summary

This study aims to investigate the effectiveness of Scatter/Gather browsing for information retrieval. We conduct a within-subject study of 24 subjects, in which each user conducted searches on Scatter/Gather system and a classic web search system, provided feedback and comments on a Scatter/Gather system based on interactive clustering of search results. Approximately half of the subjects consider that Scatter/Gather system helped them to complete the tasks more effectively as it sorted the results and filtered out the useless information. We discuss strengths and weaknesses of Scatter/Gather compared to a classic web search interface and examine influences of topic characteristics on Scatter/Gather effectiveness. It is suggested that topic familiarity and specificity had significantly influences on several categories of user perceived retrieval effectiveness. And the influences appear to be greater with the Scatter/Gather system. We find that viewing time has a moderate positive correlation with relevance and usefulness of the web page, which are highly correlated to each other.
