pellet

I'm trying to infer data using Pellet, but my application always crashes during reasoning due to an "OutOfMemoryError: Java heap space". As suggested elsewhere I have already tried to increase heap size and currently I am using these VM arguments: "-XX:MaxPermSize=256m -Xmx6144m". Furthermore I've to set 'PelletOptions.USE_CONTINUOUS = true', but so far I was only able delays the crashs for some minutes. (Longest run so far: 30 min.). I am storing data in a Jena TDB triplestore. Its total size is 170 mb and consists of 962117 statements. The ontology has been modelled in Protege and there are

I'm trying to test a simple SWRL rule. There are three Classes in my ontology: LivingPlace which has two sub-classes RuralArea and City. LivingPlace is the domain of the dataProperty hasHospital which has the range boolean. When I test the following rule with Pellet reasoner, the individual I created as a member of LivingPlace is also inferred as a member of RuralArea. LivingPlace(?lp), hasHospital(?lp, false) → RuralArea(?lp) However, what I really want to do is the reverse of this reasoning. RuralArea(?lp) → hasHospital(?lp, false) Whenever I create an individual of type RuralArea, I want

It's almost a year since Unable to download Pellet plugin for Protege 4.3 suggested that it's not available for this version. Has anything changed? It should be possible to download it from their github and just drop it into Progégé's plugins folder: https://github.com/Complexible/pellet/raw/master/protege/plugin/com.clarkparsia.protege.plugin.pellet.jar 来源： https://stackoverflow.com/questions/35663220/how-to-enable-pellet-in-protege-4-3-0

I want to use pellet reasoner with my Fuseki 2.3.1 First: I added Pellet reasoner to my config.ttl as this: ja:reasoner [ ja:reasonerClass "org.mindswap.pellet.jena.PelletReasonerFactory";] So now I have to add the jar for Pellet to fuseki This page explains how to add jars (not specificaly pellete) to fuseki https://jena.apache.org/documentation/permissions/example.html So I commet this line exec $JAVA $JVM_ARGS -jar "$JAR" "$@" and I uncommet this line java $JVM_ARGS -cp "$JAR:$APPJAR" org.apache.jena.fuseki.cmd.FusekiCmd "$@" and uncomment the line that starts with APPJAR= now I still need
