Abstract: In order to efficiently apply and effectively spread the knowledge of marine hydrocarbon, in terms of the ontology for knowledge representation, a variety of documents were translated into standard TXT documents in which all the clauses were segmented into a set of words by marine-facies and relevant ones to extract ontology concepts from marine-facies geology. On the basis of B/S infrastructure, the knowledge system of marine hydrocarbon was successfully implemented, on which the marine-facies knowledge could be automatically acquired from a variety of documents. The maintainable function of the knowledge system for majority words and relevant words guarantees the accuracy of knowledge acquisition. The knowledge of marine hydrocarbon was retrieved quickly and shared widely. The knowledge system is proved to be reliable, efficient and practical.

Key words: ontology, knowledge representation, knowledge acquisition, knowledge system, marine hydrocarbon
