owlapy 1.6.4

Release Highlights

• Contrastive explanations – SyncReasoner now supports get_contrastive_explanation() for computing fact–foil contrastive explanations, using an isolated subprocess approach to avoid Java dependency conflicts.
• Extended datatype support – Additional XSD integer datatypes (positiveInteger, negativeInteger, nonPositiveInteger, and nonNegativeInteger) are now properly mapped by the OWLAPIMapper.
• RBox retrieval & property chain axioms – SyncOntology can now retrieve RBox axioms, and object property chain axioms are now supported end-to-end.
• OWLAPI DL syntax parser & renderer – A new parser and renderer backed by OWLAPI is available, capable of handling full OWL axioms in addition to class expressions.
• Axiom justification & inconsistency explanation – The reasoner now supports computing justifications for entailed axioms and explaining ontology inconsistencies.
• Improved explanation engine – The inconsistency explainer was overhauled for better robustness, with laconic explanations now also supported.
• Reasoner API cleanup – Removed the redundant create_justification method; use create_axiom_justifications instead.
  DSPy is now an optional dependency – Install with pip install owlapy[agentic] if needed. New install modes: [min], [dev], [agentic], [all].
• Bug fixing - Fixed a bug where EBR would crash if object/data property embeddings were absent from model vocabulary.

Install/Upgrade:

pip install -U owlapy

Installation to support AGenKG:

pip install owlapy[agentic]

Full installation (supports EBR as well):

pip install owlapy[full]

owlapy 1.6.3

Release Highlights

This release introduces significant upgrades to our agentic ontology engineering capabilities, specifically enhancing AGen-KG (used to be named GraphExtractor) and some optimizations/bug fixing. You can find more details in the PRs below.

Notice: The module ontogen is deprecated and therefore removed in this release. It is now replaced by the module agen_kg. See the Ontology Generation example.

We have also updated the minimum Python version to >=3.11.

Full Changelog: 1.6.0...1.6.1

owlapy 1.6.0

Summary:

In this release we introduce a new reasoner, the embedding-based reasoner (EBR). You can find out more about it in the documentation. Moreover, owlapy now supports Semantic Web Rule Language (SWRL). Other updates include addition of new features like justification creation for why a class expression holds for a given individual or set of individuals. Lastly but not least we introduced a new module for ontology generation from text, using LLMs. We plan to keep improving towards this end.

Installation/upgrade:

pip install -U owlapy

What's Changed

• Justification by @Balramt in #149
• Added EBR by @LckyLke in #147
• Added support for Semantic Web Rule Language (SWRL) by @alkidbaci in #152

Full Changelog: 1.5.0...1.5.1

owlapy 1.5.0

Changes Summary:

• Ontology manager is deprecated.
  • The idea behind ontology manager is to manage multiple ontologies using a single managing entity. However, we don't use that functionality in owlapy and concluded that the manager does not play any important role. Therefore we are removing the manager and making it easier this way to initialize an ontology (note that Sync classes, still use owlapi's ontology manager, that stays unchanged). That also means that you can directly modify/save using the ontology instance (something that has gradually shifted from the manager to ontology itself throughout recent releases).
• Added some new functions like converting an ontology to CSV and vice-versa, and generating an ontology from triples using the help of an LLM for populating it with classes.
• ELK reasoner made available to use via SyncReasoner.
• Bug fixing and documentation update.

Installation/upgrade:
