| 摘 要： | RDFS本体提供了用于表达语义信息的通用框架,是语义网的基础。本体规模的增大使得对于特定领域知识利用的效率降低,从中抽取领域子本体可解决此问题。单个本体中包含的领域知识有限,从多个本体中抽取子本体可获取更多的领域知识。将RDFS本体抽象为图模型,根据RDFS推理规则和本体间映射,生成多个RDFS源本体的联合闭包。应用图理论构建抽取算法,生成以领域概念为节点的子图,得到所需的领域本体。该方法对于RDFS层次的领域本体抽取有一定的适用性,可快速有效地构建领域本体。 |
| 关 键 词： | 本体 子本体抽取 图模型 闭包 |

| Abstract: | RDFS ontology provides a frame for representing semantic information.It is the core of Semantic Web.The efficiency of domain-specific knowledge application decreases with the size of ontology increasing.Extracting a domain sub-ontology from source ontologies may solve this problem.Knowledge of single ontology may be not sufficient and more domain knowledge can be obtained by extracting a sub-ontology from multiple source ontologies than from single one.RDFS ontologies are abstracted as graph models.According to the RDFS inference roles and the mapping among multiple ontologies,the closure of multiple RDFS source ontologies can be constructed.We also present an algorithm based on the graph theory to extract a sub-graph with domain concepts as nodes.This sub-graph is regarded as the required domain ontology.The method is applicable to RDFS domain ontology extraction.Applying the method,a domain ontology can be built fast and effectively. |
