We follow what has been implemented inmOWL that usesJPype to bridge Python and Java Virtual Machine (JVM). Please check JPype'sinstallation page for successful JVM initialisation.
We recommend installing Pytorch prior to installing
In case the most recent Pytorch version causes any incompatibility issues, use the following command (withCUDA 11.6
) known to work:
pip install torch torchvision torchaudio --extra-index-url https://download.pytorch.org/whl/cu116
Basic usage oftorch.cuda.is_available()
returnsTrue
.
Other dependencies are specified insetup.cfg
andrequirements.txt
which are supposed to be installed along withdeeponto
.
# requiring Python>=3.8pip install deeponto
We have been informed thatopenprompt
has a conflict with several other packages that can be hardly addressed on MacOS with M1, so we now set it as an optional dependency. However, it is main dependency of the OntoLAMA code atdeeponto.complete.ontolama
. To use OntoLAMA, please installopenprompt
separately, or use the following command to install
pip install deeponto[ontolama]
To install the latest, probably unreleased version of deeponto, you can directly install from the repository.
pip install git+https://github.com/KRR-Oxford/DeepOnto.git

The base class ofOntology
][deeponto.onto.Ontology], which serves as the main entry point for introducing the OWLAPI's features, such as accessing ontology entities, querying for ancestor/descendent (and parent/child) concepts, deleting entities, modifying axioms, and retrieving annotations. See quick usage atload an ontology. Along with these basic functionalities, several essential sub-modules are built to enhance the core module, including the following:
Ontology Reasoning ([
OntologyReasoner
][deeponto.onto.OntologyReasoner]): Each instance of$\textsf{DeepOnto}$ has a reasoner as its attribute. It is used for conducting reasoning activities, such as obtaining inferred subsumers and subsumees, as well as checking entailment and consistency.Ontology Pruning ([
OntologyPruner
][deeponto.onto.OntologyPruner]): This sub-module aims to incorporate pruning algorithms for extracting a sub-ontology from an input ontology. We currently implement the one proposed in [2], which introduces subsumption axioms between the asserted (atomic or complex) parents and children of the class targeted for removal.Ontology Verbalisation ([
OntologyVerbaliser
][deeponto.onto.OntologyVerbaliser]): The recursive concept verbaliser proposed in [4] is implemented here, which can automatically transform a complex logical expression into a textual sentence based on entity names or labels available in the ontology. Seeverbalising ontology concepts.Ontology Projection ([
OntologyProjector
][deeponto.onto.OntologyProjector]): The projection algorithm adopted in the OWL2Vec* ontology embeddings is implemented here, which is to transform an ontology's TBox into a set of RDF triples. The relevant code is modified from the mOWL library.Ontology Normalisation ([
OntologyNormaliser
][deeponto.onto.OntologyNormaliser]): The implemented$\mathcal{EL}$ normalisation is also modified from the mOWL library, which is used to transform TBox axioms into normalised forms to support, e.g., geometric ontology embeddings.Ontology Taxonomy ([
OntologyTaxonomy
][deeponto.onto.OntologyTaxonomy]): The taxonomy extracted from an ontology is a directed acyclic graph for the subsumption hierarchy, which is often used to support graph-based deep learning applications.
Individual tools and resources are implemented based on the core ontology processing module. Currently,
BERTMap [1] is a BERT-based ontology matching (OM) system originally developed inrepo but is now maintained in
$\textsf{DeepOnto}$ . SeeOntology Matching with BERTMap & BERTMapLt.Bio-ML [2] is an OM resource that has been used in theBio-ML track of the OAEI. SeeBio-ML: A Comprehensive Documentation.
BERTSubs [3] is a system for ontology subsumption prediction. We have transformed its originalexperimental code into this project. SeeSubsumption Inference with BERTSubs.
OntoLAMA [4] is an evaluation of language model for ontology subsumption inference. SeeOntoLAMA: Dataset Overview & Usage Guide for the use of the datasets and the prompt-based probing approach.
HiT (External) [6] is a hierarchy embedding model derived from re-training BERT-like models in hyperbolic space. SeeHiT Models on Huggingface Hub for options and usage.
