摘　　要：在电力领域,由于异构的多数据源带来的语义冲突问题越来越成为制约信息集成的难点。基于本体的概念,提出一个电力信息语义集成方案。从分布式的电力数据源中提取出局部本体,然后将局部本体整合为全局本体,从而消除数据库之间的信息冗余与冲突,能够实现多维查询、信息推理和本体演化等功能,从语义层面实现电力信息的无歧义共享与重用。In power supply industry, problems of semantic conflict incurred from heterogeneous multiple data resources become more and more serious, so as to be regarded as bottleneck of information integration. Based on the concept of ontology,in this paper it proposed a scheme of semantic integration for power information. Local ontologies are picked up from databases and documents of distributed power systems, and then are integrated into global ontology, so the redundancy and the inconsistency among heterogeneous databases are eliminated. By this method, functions such as multi-dimension query, concept reasoning and ontology evolution would be realized too, and the unambiguous share and reuse of power information are realized on semantic level.
