My book "Ontologies with Python" has just been published by Apress editions.

This 350-pages book describes how to use OWL 2.0 ontologies in Python 3.x, with the Owlready2 Python module for ontology-oriented programming.

Use ontologies in Python, with the Owlready2 module developed for ontology-oriented programming. You will start with an introduction and refresher on Python and OWL ontologies. Then, you will dive straight into how to access, create, and modify ontologies in Python. Next, you will move on to an overview of semantic constructs and class properties followed by how to perform automatic reasoning. You will also learn about annotations, multilingual texts, and how to add Python methods to OWL classes and ontologies. Using medical terminologies as well as direct access to RDF triples is also covered.

Python is one of the most used programming languages, especially in the biomedical field, and formal ontologies are also widely used. However, there are limited resources for the use of ontologies in Python. Owlready2, downloaded more than 60,000 times, is a response to this problem, and this book is the first one on the topic of using ontologies with Python.

What You Will Learn:

• Use Owlready2 to access and modify OWL ontologies in Python

• Publish ontologies on dynamic websites

• Perform automatic reasoning in Python

• Use well-known ontologies, including DBpedia and Gene Ontology, and terminological resources, such as UMLS (Unified Medical Language System)

• Integrate Python methods in OWL ontologies

Who Is This Book For: Beginner to experienced readers from biomedical sciences and artificial intelligence fields would find the book useful.

The book is an updated translation of the French book "Python et les ontologies" published at ENI éditions last year.

Owlready is a Python module for ontology-oriented programming. It can load OWL 2.0 ontologies and manipulate them transparently in Python.

This new release includes a new module for displaying entities in Description Logics (DL), and bugfixes.

Here are the changes:

• Module owlready2.dl_render allows rendering entities to Description Logics (contributed by Simon Bin)

• Bugfixes: - Adjustment in the comparison of strings from SameAs and DiferrentFrom, allowing equal comparison regardless of the case-sensitive (contributed by Thiago Feijó) - Fix transitive equivalent_to relations between classes and OWL constructs - Fix AnnotationProperty[entity] where entity is a predefined OWL entity (e.g. comment or Thing) - Fix entity.AnnotationProperty where entity is a predefined OWL entity (e.g. comment or Thing) - Fix HermiT when reasoning on several ontologies with imports statement - Ignore "A type A", with a warning

Owlready is a Python module for ontology-oriented programming. It can load OWL 2.0 ontologies and manipulate them transparently in Python.

This new release includes a few new features, and bugfixes.

Here are the changes:

• Allow the declaration of custom datatypes with declare_datatype()

• Support the annotation of annotations (e.g. a comment on a comment)

• search() now support the "subproperty_of" argument

• search() now support the "bm25" argument (for full-text searches)

• Bugfixes: - Fix Concept.descendant_concepts() in PymedTermino2 - Update already loaded properties when new ontologies are loaded - Now accept %xx quoted characters in file:// URL - Improve error message on punned entities - Property.get_relations() now considers inverse properties - Fix "AttributeError: 'mappingproxy' object has no attribute 'pop'" error - Fix Thing.instances()

Owlready is a Python module for ontology-oriented programming. It can load OWL 2.0 ontologies and manipulate them transparently in Python.

This new release includes several small changes and bugfixes. It now uses the Git versionning system, instead of Mercurial.

Here are the changes:

• Add owlready2.reasoning.JAVA_MEMORY

• Move development repository to Git

• Bugfixes: - Fix parsing of NTriples files that do not end with a new line - Fix KeyError with Prop.python_name when several properties share the same name - Fix get_ontology() calls in Python module imported by ontologies in a World that is not default_world - Fix use of PyMedTermino2 in a World that is not default_world - Fix World.as_rdflib_graph().get_context(onto) for ontology added after the creation of the RDFLIB graph - Fix destroying SWRL rules - Fix disjoint with non-atomic classes
