Hierarchical visualization of a semantic network

摘要

The present invention provides methods, systems and apparatus for generating a visualized hierarchy model for a semantic network, and for browsing a semantic network and a semantic network browser. An example of a semantic network comprises a plurality of concepts and a plurality of relation instances each for connecting two concepts. The method for generating a visualized hierarchy model for a semantic network comprises: determining the similarities among said concepts based on the connection relations of said plurality of concepts in said semantic network; and clustering the concepts with high similarities one by one, so as to form a visualized hierarchy model of said semantic network.
