HermiT Reasoner: Using HermiT from Java
reasoher Add the Maven Dependecy to your project: Get Started with Astyanax, the Cassandra java library by Netflix. Prints the hierarchies into a functional style syntax ontology all nicely sorted alphabetically. A Reasoner is associated with a single knowledge base, which is “loaded” when the reasoner is constructed.
This can be controlled via a configuration setting. The release should be compatible with Java 1.
Internal details of the loading and reasoning algorithms can be configured in the Reasoner constructor and do not change over the lifetime of the Reasoner objectinternal data structures and caches are optimized for a particular configuration.
Alternatively, the file org. Creates a new reasoner object with the parameters for blocking, expansion strategy etc as specified in the given configuration object. Reazoner that reasoning reasoneg DL Safe rules is incomplete if the ontology contains property chains or transitivity axioms and complex properties are used in the rule bodies.
New Blog Post!
Can be used to retrieve a tableau for axioms in the given ontology manager plus an additional set of axioms. Let’s see why the ontology is inconsistent. This is done via a ReasonerFactory object. Ontologies which previously required minutes or hours to classify can often by classified in seconds by HermiT, and HermiT is the first reasoner able to classify a number of ontologies which had previously proven too complex for any available system to handle.
By default, HermiT will use the set of options which provide optimal performance. Sign up using Email and Hermut.
Then the given manager is used to find all required imports for the given ontology and the ontology with the imports is loaded into the reasoner and the data factory of the manager is used to create fresh concepts during the preprocessing phase if necessary. Creates a new reasoner object loaded with the given ontology and the given description graphs.
OWLReasoner Answers queries about the logical implications of a particular knowledge base. Ignazio 7, 1 9 By default a full classification of all atomic terms in the knowledge base is also performed at this time which can take quite a while for large or complex ontologiesbut this behavior can be disabled as a part of the Reasoner configuration.
We now provide nightly builds of HermiT. HermiT uses direct semantics and passes all OWL 2 conformance tests for direct semantics reasoners.
A default configuration can be obtained by just passing new Configuration. Given an OWL file, HermiT can determine whether or not the ontology is consistent, identify subsumption relationships between classes, and much more.
Reasoner (HermiT API) – Javadoc Extreme
HermiT provides a command-line interface for common reasoning tasks, including classification and query answering. We have now released HermiT 1. When creating the reasoner, the given configuration determines the parameters for blocking, expansion strategy etc.

These are experimental and not guaranteed to work, but for users who eagerly await some new feature or bug-fix, it can be worth trying. I am trying to use Hermit Reasoner to check consistency.
