我想在Fuseki 2.3.1 中使用颗粒推理机
首先:我在配置.ttl中添加了Pellet推理器,如下所示:
ja:reasoner
[ ja:reasonerClass
"org.mindswap.pellet.jena.PelletReasonerFactory";]
所以现在我必须将Pellet的罐子添加到fuseki 中
本页介绍如何将罐子(不是特定的pellete)添加到fuseki
https://jena.apache.org/documentation/permissions/example.html
所以我用通讯
exec$JAVA$JVM_ARGS-jar"$jar"$@"
我取消了这条线路的连接
java$JVM_ARGS-cp"$JAR:$APPJAR"org.apache.jena.fuseki.cmd.FusekiCmd"$@"
并取消注释以APPJAR=
开头的行
现在我仍然需要知道和下载佩莱的罐子,我找到了这个链接https://datababel.wordpress.com/2013/06/26/fuseki-using-pellet-inference/上面写着哪些是罐子,
我从maven下载了最新的可用版本,它们是:
pellet-jena-ignazio1977-2.4.0-ignazio 1977.jar
pellet-rules-2.3.6-ansell.jar
pellet-el-2.3-ansell.jar
pellet-datatypes-2.3.6-ansell.jar
pellet-core-ignazio1977-2.4.0-ignazio 1977.jar
aterm-java-1.8.2-p1.jar
公共集合4-4.1-javadoc.jar
公用集合4-4.1.jar
我将它们添加到fuseki服务器脚本中,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
(它们在fuseki的主目录中)
我跑了/fuseki服务器,我得到这个错误

请帮忙
提示:我不知道我尝试的是对是错,我只想把佩莱推理机加入fuseki
更新
在ignazio告诉我我正在搅拌罐子之后,
我去了Pellet git小屋,下载了src,并使用maven编译并获得了罐子
然后我把我使用的罐子改成:
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

解决方案:请改用openllet。只需在配置文件中更改为ja:reasonerClass "openllet.jena.PelletReasonerFactory"
,然后将openllet分发版和其他需要的jar文件下载到类路径中。
说明:错误
expected class org.apache.jena.reasoner.ReasonerFactory, but had class org.mindswap.pellet.jena.PelletReasonerFactory
是由于芯块的org.mindswap.pellet.jena.PelletReasonerFactory
实现了与Fuseki中使用的接口(org.apache.jena.reasoner.ReasonerFactory
)不同的旧接口(com.hp.hpl.jena.reasoner.ReasonerFactory
)。
openllet的openllet.jena.PelletReasonerFactory
实现了正确的接口(org.apache.jena.reasoner.ReasonerFactory
)。
检查他们的源代码:
openllet的PelletReasonerFactory.java
pellet的PelletReasonerFactory.java
您的错误是
expected class org.apache.jena.reasoner.ReasonerFactory, but had class org.mindswap.pellet.jena.PelletReasonerFactory
我不是专家,但看起来您类路径中当前Jena的Pellet工厂与预期的类不匹配。
Fuseki提供了哪个版本的Jena,Pellet目前使用的是哪个版本?
