Improving the Navigability of Tagging Systems with Hierarchically Constructed Resource Lists: A Comparative Study

Abstract. This paper presents the first practical results of a novel resource list gen-eration algorithm based on a hierarchical network model which demonstrably improves the navigability of tagging systems. In particular, the results of a formal experiment show that the new algorithm is able to create tag networks which are significantly more navigable than the one generated by the currently most widely used resource list generation- the reverse chronologi-cal sorting resource list generation algorithm
