摘要: 为了有效利用和普及海相油气地质知识,采用本体的知识表示,通过各类文档转换为标准TXT文档后,以专业词条和关联关系词条为基础,实现文档句子的词条分割和概念本体的提取。基于B/S结构,实现了海相油气地质知识系统,完成了海相油气地质知识从各类文档中进行知识的自动获取。通过该系统的词条维护功能,确保提高知识获取的精度。最后在海相油气地质知识系统上实现知识检索和共享。实践证明,该知识系统可靠性强,性能良好,已达到实用水平。

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
