sparql - Pellet internalReasonerException in OWL API -

have been stuck 1 day , kind enough help? have loaded ontology imported sweet(semantic web earth , environmental ontology). did sparql query on it, , got such answer: "object property haslowerbound used hasvalue restriction value literal: "0"^^integer". (haslowerbound, have checked in sweet, datatype ontology in sweet)

how can solve problem?

here code wrote , error got,thank help~

haslowerbound parsed data property , annotation property.

pellet checking data property case , assumes if property not data property must object property. case owl 2 ontologies, ontology not being parsed owl 2 compatible ontology - punning of annotation property , data property not allowed.

i'm not sure yet whether problem in ontology or in owlapi parsing of it.

edit: it's parsing issue. haslowerbound declared in relamath.owl data property. relamath.owl imports reprmath.owl, uses haslowerbound not declare it. reprmath.owl imports relamath.owl, there cyclic import there.

the problem that, during parsing: - relamath.owl parsed, import found, reprmath.owl import resolved; no declarations parsed yet. - reprmath.owl parsed, import found. relamath.owl being parsed, call nothing. entities declared in relamath.owl included while parsing reprmath.owl. problem: entities have not been parsed yet, set empty. haslowerbound found in reprmath no declaration exists yet. therefore owlapi defaults annotationproperty. - relamath.owl parsing continues, declaration found.

final result: ontology importing relamath.owl has illegal punning haslowerbound. owlapi bug.

workaround: add data property declaration reprmath.owl:

<owl:datatypeproperty rdf:about="#haslowerbound"/> 

this might need done in more 1 ontology.
