The paper describes an experiment on the navigation efficiency of social bookmarking service for information discovery. The purpose is to evaluate the effects of navigation information that can be used in choosing users' libraries, which includes the number of bookmarks in each library, the ratio of user's bookmarks in a bookmark collection, and the ratio of bookmarks with certain tags in each library. The experiment was performed by computer simulation for an example real dataset. The navigation efficiency was evaluated by the average number of bookmarks browsed to find a randomly selected target bookmark for each randomly selected tag. The result shows that all these information effect on the navigation efficiency with statistical significance.
