It implements the Rete/UL algorithm as described in [Production Matching for Large Learning Systems](http://reports-archive.adm.cs.cmu.edu/anon/1995/CMU-CS-95-113.pdf) by Robert B. Doorenbos, an extension of [Forgy's](http://dx.doi.org/10.1016/0004-3702%2882%2990020-0) original Rete algorithm.\n\n### Goals\nArachne was developed initially to support reasoning within the [Noctua/Minerva](https://github.com/geneontology/noctua) system. This use case calls for:\n* Scalable handling of very large ontologies (millions of axioms/rules).\n* Adequate performance, with large rule sets, for smallish datasets of hundreds to thousands of triples (materialize all inferences in \u003c1 second).\n* Simultaneous reuse of reasoner, once all rules have been loaded, for any number of datasets, without re-incurring initialization time.\n\n## Usage\n\n```\nUsage\n\n arachne [options] : Command-line operations for Arachne RDF rule engine\n\nOptions\n\n   --data           : file or folder of RDF data files\n   --export         : export RDF triples to Turtle file\n   --indirect-types : mark indirect types with additional triple\n   --inferred-only  : export inferred triples only\n   --ontology       : OWL ontology to import into reasoning rules\n   --rules          : Jena-syntax rules file to import\n```\n\nTo compute Abox inferences for an instance dataset `data.ttl` which uses classes and properties from some ontology `ont.owl`, a typical command line would be:\n\n```\narachne --ontology=ont.owl --data=data.ttl --export=output.ttl\n```\n\n## Building\n\nInstall `sbt` (Scala Build Tool) on your system. For Mac OS X, it is easily done using [Homebrew](http://brew.sh):  `brew install sbt`. `sbt` requires a working Java installation, but you do not need to otherwise install Scala.\n\n`sbt compile`\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fbalhoff%2Farachne","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fbalhoff%2Farachne","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fbalhoff%2Farachne/lists"}
