HFCT: A Hybrid Fuzzy Clustering Method for Collaborative Tagging
Lixin Han, Guihai Chen · 2007 International Conference on Convergence Information Technology (ICCIT 2007) · 2007
In recent years, there has been considerable interest in collaborative tagging. This paper proposes a hybrid fuzzy clustering method for collaborative tagging. Key feature of the method includes using a combination of the fuzzy c-means and the subtractive clustering to handle collaborative tagging problems. The method allows a resource to belong to more than one laggings with different membership grade. The HFCT method need not know in advance the number of laggings, in order to avoid the difficulty of initial guesses of the number of taggings.
