[Objective] The thesis explores the visualization and the measurement method of the tags semantic distance in folk sonomy, and lays foundations for optimizing the navigation algorithm of related tags.[Context] The thesis weakens the "topic drift" in the navigation of related tags and improves the knowledge service performances in folk sonomy websites such as Bib Sonomy by the visualization of the semantic distance.[Methods] The thesis designs an algorithm which helps choose the tested tags sets and measure the semantic distance, and visualizing the final results by a map with threshold value, based on the data in Bib Sonomy.[Results] There exist close semantic tags and distants emantic tags in test set, which affects the topic drift level in the behavior of the related tags navigation.[Conclusions]Semantic visualization method help users to distinguish semantic attributes between the related tags sets, and improve the navigation performances of the tags.
