Jena Fuseki是一个基于Apache Jena的SPARQL服务器,它提供了对RDF数据的存储、查询和推理功能。然而,Jena Fuseki本身并不直接支持OWL推理,因为OWL(Web本体语言)是一种比RDF(资源描述框架)更为复杂和强大的本体语言。
要在Jena Fuseki中使用OWL推理,你需要使用Apache Jena的ARQ模块中的推理器(Inference API)。以下是一些建议,可以帮助你解决Jena Fuseki对OWL推理没有反应的问题:
例如,使用GenericRuleReasoner:
import org.apache.jena.rdf.model.Model;
import org.apache.jena.reasoner.GenericRuleReasoner;
import org.apache.jena.reasoner.Reasoner;
import org.apache.jena.reasoner.rulesys.GenericRuleReasonerConfig;
Model model = ... // 加载你的RDF模型
Reasoner reasoner = new GenericRuleReasoner(new GenericRuleReasonerConfig());
reasoner = reasoner.bindSchema(model);
Model inferredModel = reasoner.apply(model);
例如,使用Pellet推理器:
import org.apache.jena.rdf.model.Model;
import org.apache.jena.reasoner.Reasoner;
import org.apache.jena.reasoner.pellet.PelletReasonerFactory;
Model model = ... // 加载你的RDF模型
Reasoner reasoner = PelletReasonerFactory.theInstance().create();
reasoner = reasoner.bindSchema(model);
Model inferredModel = reasoner.apply(model);
