【Abstract】This paper introduces the definition, the characteristic and the limitation of PageRank algorithm used by Google and other search
engine. It develops a system, ocean search system, which is based on Ontology and PageRank algorithm. However, because of PageRank algorithm’s
insufficiencies in this system, a new algorithm is proposed and applied in the system’s consummation. It introduces the functions of the ocean search
system and takes an illustration and test to the new algorithm.
