摘要: Disclosed is a system for analyzing bio chip using Gene Ontology (hereinafter referred to “GO”) and method thereof. According preferred embodiment of the present invention, it provided comprising: GO (gene ontology) term assigning part receiving statistical clustering data obtained from empirical results chip, relevant terms every gene contained in each cluster; code converting assigned by genes into codes, comprising group predetermined numbers; biological meaning extracting calculating pseudo distances between one on tree structure corresponding cluster, at least average distance or maximum calculated distances, all included determining an optimum matching with cluster.
