我想在我的 Fuseki 2.3.1 中使用颗粒推理机
首先:我将 Pellet Reasoner 添加到我的 config.ttl 中，如下所示:
ja:reasoner
[ ja:reasonerClass
"org.mindswap.pellet.jena.PelletReasonerFactory";]
所以现在我必须将 Pellet 的 jar 添加到 fusioni
本页介绍了如何将 jar (不是特别是颗粒)添加到fuseki
https://jena.apache.org/documentation/permissions/example.html
所以我评论了这一行
exec $JAVA $JVM_ARGS -jar "$JAR" "$@"
我取消了这一行的注释
java $JVM_ARGS -cp "$JAR:$APPJAR" org.apache.jena.fuseki.cmd.FusekiCmd "$@"
并取消注释以 APPJAR=
现在我仍然需要了解并下载 Pellete 的 jar ，我找到了这个链接 https://datababel.wordpress.com/2013/06/26/fuseki-using-pellet-inference/这说明哪些是 jar ，
我从maven下载了最新的可用版本，它们是:
pellet-jena-ignazio1977-2.4.0-ignazio1977.jar
pellet-rules-2.3.6-ansell.jar
pellet-el-2.3.6-ansell.jar
pellet-datatypes-2.3.6-ansell.jar
颗粒核心-ignazio1977-2.4.0-ignazio1977.jar
aterm-java-1.8.2-p1.jar
commons-collections4-4.1-javadoc.jar
commons-collections4-4.1.jar
我将它们添加到fuseki-server脚本中，如下所示:
APPJAR=pellet-jena-ignazio1977-2.4.0-ignazio1977.jar:pellet-rules-2.3.6-ansell.jar:pellet-el-2.3.6-ansell.jar:pellet-datatypes-2.3.6-ansell.jar:pellet-core-ignazio1977-2.4.0-ignazio1977.jar:aterm-java-1.8.2-p1.jar:commons-collections4-4.1-javadoc.jar:commons-collections4-4.1.jar
(它们位于fuseki的主目录中)
我运行 ./fuseki-server，并收到此错误

请帮忙
提示:我不知道我尝试的是否正确，我想要的只是将 Pellet Reasoner 包含到 fusione
更新
在ignazio告诉我我正在混合 jar 之后，
我去了 Pellet git hut 并下载了 src 并使用 maven 来编译并获取 jars
然后我将我正在使用的 jar 更改为:
commons-collections4-4.1-javadoc.jar:commons-collections4-4.1.jar:pellet-cli-2.4.0-SNAPSHOT.jar:jena-core-2.13.0.jar:pellet-jena-2.4.0-SNAPSHOT.jar:pellet-modularity-2.4.0-SNAPSHOT.jar:pellet-owlapi-2.4.0-SNAPSHOT.jar:pellet-pellint-2.4.0-SNAPSHOT.jar

最佳答案
解决方案:
使用openllet反而。
只需在配置文件中更改为 ja:reasonerClass "openllet.jena.PelletReasonerFactory"，并将 openllet 发行版和其他所需的 jar 文件下载到类路径即可。
说明:错误
预期为 org.apache.jena.reasoner.ReasonerFactory 类，但有 org.mindswap.pellet.jena.PelletReasonerFactory 类
是由于颗粒的 org.mindswap.pellet.jena.PelletReasonerFactory 实现旧接口(interface) (com.hp.hpl.jena.reasoner.ReasonerFactory) 导致的与 Fuseki 中使用的接口(interface) (org.apache.jena.reasoner.ReasonerFactory) 不同。
openllet 的 openllet.jena.PelletReasonerFactory 实现了正确的接口(interface) (org.apache.jena.reasoner.ReasonerFactory)。
检查他们的源代码:
