摘　　要：介绍了利用基于领域本体(Ontology)的知识库和一阶谓词推理引擎构建的语义互联网(SemanticWeb)应用:铁路信息查询系统.该系统通过引入W3C提出的资源描述框架和Ontolo-gy,将互联网的标记信息进行语义标注构建事实库.该系统构建了铁路领域的本体集(Ontologies),依此将从互联网上获取的信号映射到实例,形成语义化的知识库.在此基础上,客户端接收来自用户的查询请求,将其传送至服务器端,并将其提交给一阶逻辑推理引擎,结合事实库和规则库进行处理得到最终的查询结果,客户端以文本和图形两种方式显示给用户.This paper introduced a railway querying system as an application that makes use of ontology-based knowledge repository and first order inference engine. This system utilizes resource description framework, ontology and some related extensions put forward by W3C and annotates the Web information semantically according to the ontologies definition to construct the fact repositories. This system takes railway domain as an example to construct the domain ontologies and maps the information from internet into instances in terms of the domain ontologies. Client receives the users' query requests and sends them to server where there is a first-order inference engine to deal with them. The final query results are sent back to client and displayed in graphics and text way. This system provides some experience and mode for designing and developing semantic Web-based application.
