HermiT Reasoner: Using HermiT

Post as a guest Name. Let’s see why the ontology is inconsistent. We have now released HermiT 1. Add the Maven Dependecy to your project: 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.

Creates a new reasoner object with the parameters for blocking, expansion strategy etc as reaosner in the given configuration object. Reasoner cannot be cast to org. This can be controlled via a configuration setting.

HermiT from the command line HermiT provides a command-line interface for common reasoning tasks, including classification and query answering.

JUnit test reports are now available and unless we are in the middle of major changes, HermiT should always pass all tests. 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.

A Reasoner is associated with a single knowledge base, which is “loaded” hermjt the reasoner is constructed. By default, HermiT will use the set of options which provide optimal performance. A default configuration can be obtained by just passing new Configuration. OWLReasoner Answers queries about the logical implications of a particular knowledge base. Given an OWL file, HermiT can determine whether or not the ontology is consistent, identify subsumption relationships between classes, and much more.


Betafish 2 4 I am trying to use Hermit Reasoner to check consistency. Email Required, but never shown.

Ignazio 7, 1 9 HermiT uses direct semantics and passes all OWL 2 conformance tests for direct semantics reasoners. When creating the reasoner, the given configuration determines the parameters for blocking, expansion strategy etc. This is done via a ReasonerFactory object.

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 germit optimized for a particular configuration.
