Owl Ontology example

How is OWL Used 1. build an ontology create the ontology name classes and provide information about them name properties and provide information about them (would be slightly inaccurate to say fidenefl here) 2. state facts about a domain provide information about individuals 3. reason about ontologies and fact B.2 Examples of Entailments in OWL DL and OWL Full. OWL DL supports the entailments that one would expect, as long as the vocabulary can be shown to belong to the appropriate piece of the domain of discourse. For example, John friend Susan . does not OWL DL entail When embedding the example OWL ontology to RDF, every statement must be converted to triples - see the figure below. For example, the ∃R.C restriction is formed by anonymous resource of type owl:Restriction Examples: OWL vs Databases hasPet some owl:Thing SubclassOf: Human Phoenix SubclassOf: petOf only Wizard HarryPotter: Wizard DracoMalfoy: Wizard HarryPotter hasFriend RonWeasley HarryPotter hasFriend HermioneGranger HarryPotter hasPet Hedwig RonWeasley ̸= HermioneGranger HarryPotter: hasFriend only fHerminoeGranger RonWeasley

This document presents a simple example ontology and a number of illustrative examples of reasoning. Although not intended to be comprehensive, the hope is that the examples will aid users of OWL to understand why the inferences are being drawn in their ontologies. 2. Ontology. An ontology about people is available in RDF/XML Example of how a simple OWL ontology / RDFS vocabulary could be defined with JSON-LD, defining the meaning of properties and classes. The second file shows the RDF triples of the vocabulary by using the JSON-LD sandbox That is, by combining a logical reasoner (called JTP) with an OWL ontology, this example implementation operates over a domain that can one day exist as a web of interfacing definitions. Thus the agent's operation can be described in three parts--consulting the ontology, performing queries, and outputting results. An example interaction traced through these three phases will precede an elaboration on why this application uses ontologies, and how future agents might continue to do so

Since the description of an XML namespace can be lengthy, a prefix is usually assigned to each, in order to simplify referring to a term. For example, the set of terms that define the OWL language is itself an ontology, defined in XML. Its namespace, then is described as follows SaOn-Software Application Ontology: An example ontology for searching, retrieving and using software applications, components. shuttle-crew-ont.owl: An ontology about the crew from a space shuttle.

The next example says that the class WhiteBurgundy is exactly the intersection of white wines and Burgundies. Example 4-3: XML Presentation Syntax for owlx:Class [axiom] <owlx:Class owlx:name=WhiteBurgundy owlx:complete=true> <owlx:Class owlx:name=#Burgundy /> <owlx:Class owlx:name=#WhiteWine /> </owlx:Class> Moreover, users have found it easy to use TEX-OWL for authoring a small example ontology and that, in general, this syntax is better to use for writing ontologies by hands than other OWL 2 syntaxes.

For example, : Dupond is an instance of the class : Professor. The ontology also includes relationships between classes, that denote natural relationships between individuals in the real world. For instance, the university ontology includes the relationship, e.g., : TeachesIn

NTriples is a very simple format and is natively supported by Owlready2. RDF/XML is the most common format; it is also natively supported by Owlready2 (since version 0.2). OWL/XML is supported using a specific parser integrated to Owlready2. This parser supports a large subset of OWL, but is not complete Here is our example OWL ontology again, this time with some added classes and subclasses. We define three plant classes: the flowering plants class and shrubs class. which are both subclasses of the planttype class For example, here is a small ontology with two classes and an individual, which has one data property: The same axiom can be written in several ways. The most common is the XML/RDF format, the OWL 2 specification uses the functional syntax format, the Protege authors developed a shorter Manchester format, and the most concise format is Turtle

Querying an OWL ontology. In an OWL ontology, we have to link classes with a certain integer. For example, we have a LWM2MTemperatureObject class which has always an objectID of 3303. (we're modelling a subset of the LwM2M specifications where we describe which connections there are between objects and resources) Mapping between Relational Databases and OWL Ontologies: an Example 103 Class personID instances are populated from student and teacher tables (idcode column). Classes Asistant, AssocProfessor and Professor all get instance data from one table teacher but each has a different filtering. It means that string data 'level_code=' mus // A simple example of how to load and save an ontology We first need to // obtain a copy of an OWLOntologyManager, which, as the name suggests, // manages a set of ontologies

1. Overview. eClassOWL is an OWL ontology for describing the types and properties of products and services on the Semantic Web (also known as the Web of Linked Data). eClassOWL is meant to be used in combination with the GoodRelations ontology for e-commerce, which covers the commercial aspects of offers and demand, e.g. prices, payment, or delivery options Building OWL Ontologies with Protege CS 431 - April 9, 2008 We'll start with the first example .

  1. The ontology will be downloaded as a zip containing the root-ontology.owl file. Once Owl file is downloaded, SDI provides API to upload API: Base URI /ontologyJobs. Sample Ontology for example of Air Quality App is as below: Sampl
  2. The example makes use of an OWLReasoner to calculate the class hierarchy, then navigates the structure obtained, printing out basic information for each of the classes. The example either uses a StructuralReasoner, which returns information about the hierarchy based solely on the assertions that are made in the ontology
  3. Examples. The W3C OWL 2 Web Ontology Language provides syntax examples. Tea ontology. Consider an ontology for tea based on a Tea class. First, an ontology identifier is needed. Every OWL ontology must be identified by a URI (http://www.example.org/tea.owl, say). This example provides a sense of the syntax. To save space below, preambles and prefix definitions have been skipped
  4. I have to query an ontology version 1.4, with a SPARQL 1.1 endpoint, so I can't use the OWL 2 semantic like ClassAssertion etc... several properties in the ontology have this format: <owl
  5. ontology research. For example, models for many different domains need to represent the notion of time. This representation includes the notions of time intervals, points in time, relative measures of time, and so on. If one group of researchers develops such an ontology in detail, others can simply reuse it for their domains. Additionally, if we need to build a large . 2 ontology, we can.
  6. Protégé fully supports the latest OWL 2 Web Ontology Language and RDF specifications from the World Wide Web Consortium. Extensible Open Source Environment Protégé is based on Java, is extensible, and provides a plug-and-play environment that makes it a flexible base for rapid prototyping and application development

OWL Example with RDF Graph - Introduction to ontologies

OWL Reasoning Example

  1. g languages have support for RDF parsers, which is one reason why the default serialization for OWL is usually an RDF one. In theory it makes it more accessible. However, RDF can be a very low level way to process.
  2. Ontology of Functions is included in the OWL version of the General Formal Ontology (see upper level ontologies) FuGO Functional Genomics Ontology aims to provide consistent annotation of functional genomics experiments, regardless of the particular field of study (transcriptomics, proteomics and metabolomics, etc)
  3. For example, an OWL ontology can define a restriction saying that values of a restricted property must again fulfill some other restrictions described in terms of values of their properties. In SHACL this is achieved by shapes that reference other shapes, e.g. using sh:node and sh:property. With some notable exceptions that we will explain below, the expressivity of OWL is comparable to the.

  5. Ontologies are serialised as RDF, so they can be imported using plain n10s.rdf.import.fetch but the n10s.onto.import.fetch method will give us a higher level of control over how an RDFS or OWL ontology is imported into Neo4j. It's important to note that this procedure exclusively imports the following

To demonstrate how an RDFS/OWL ontology can be imported into Neo4j, we are going to show how we import the W3C Organizational Ontology using the neosematics tools. There will be other approaches to achieve this, of course, but this is a good starting point to explore. What is neosemantics? Before we dive straight into our worked example, what exactly is neosematics? Neosemantics (https. OWL class restrictions¶ Keep the previously opened interim ontology open. As previously stated, in OWL we use object property to describe binary relationships between two individuals (or instances). We can also use the properties to describe new classes (or sets of individuals) using restrictions. A restriction describes a class of individuals based on the relationships that members of the. The OWL Standard and Ontology Modelling. In recent years, there has been an uptake of expressing ontologies using ontology languages such as the Web Ontology Language (OWL). OWL is a semantic web computational logic-based language, designed to represent rich and complex knowledge about things and the relations between them. It also provides detailed, consistent and meaningful distinctions.

OWL 2 punning should be used to capture the two facets of Lion and Hiena in this example: (i) as instances of AnimalSpecies, and (ii) as subclasses of Animal. Note that the partitioned type (in the example Animal) may or may not be declared to be a disjoint union of the explicitly enumerated subclasses (such as Lion, Hiena) Welcome to Owlready2's documentation! Owlready2 is a package for ontology-oriented programming in Python. It can load OWL 2.0 ontologies as Python objects, modify them, save them, and perform reasoning via HermiT (included). Owlready2 allows a transparent access to OWL ontologies (contrary to usual Java-based API) 1. The following code should read an existing ontology file ( test.owl) and save it in a different format ( test-format.owl ). Make sure the original file exists and contains axioms (the getAxiomCount () method. //Create the manager OWLOntologyManager manager = OWLManager.createOWLOntologyManager (); //File with an existing ontology - make sure. Owlready2 is a module for ontology-oriented programming in Python 3, including an optimized RDF quadstore. Owlready2 can: Import OWL 2.0 ontologies in NTriples, RDF/XML or OWL/XML format.

It is designed to improve the efficiency and quality of building, using, and maintaining knowledge bases

How does it work? (OWL Example Wine Agent

OWL ontologies can be further classified as OWL-Lite, OWL-DL, and OWL Full. OWL-Lite restricts the cardinality minimum and maximum values to 0 or 1. OWL-DL relaxes this restriction by allowing minimum and maximum values. OWL Full allows instances to be also defined as a class, which is not allowed in OWL-DL and OWL-Lite ontologies Ontology source.

Data Modeling, RDF, & OWL - Part One: An Introduction To

OWL (the Web Ontology Language) is being designed by the W3C Web Ontology Working Group to provide a language that can be used for applications that need to understand the content of information instead of just understanding the human-readable presentation of content. OWL facilitates greater machine readability of web content than that supported by XML, RDF, and RDF-S by providing additional. Ontology files: General information. Released monthly; Available in the following formats: OBO 1.4 files are human-readable (in addition to machine-readable) and can be opened in any text editor; OWL files can be opened with Protégé; GO subsets (slims) are available in the above formats as well as JSON: . JSON files should be loaded with ontobio, although they can be opened with any text edito A good example of a transitive property is the geneological 'ancestor of' relationship. We can make a property transitive in Protege by simply selecting the transitive check box. OWL class restrictions¶ As previously stated, in OWL we use object property to describe binary relationships between two individuals (or instances). We can also use the properties to describe new classes (or sets. Note that the source ontology is OWL - the OBO version may have less axioms. Another difference between the two formats is that the OWL makes use of imports, whereas everything is combined into one with the obo file. Products. ro.owl: Relation Ontology Canonical edition ro.obo: Relation Ontology in obo format The obo edition is less expressive than the OWL, and has imports merged in ro.json. This data article reports on a new set of 234 competency questions for ontology development and their formalisation into a set of 131 SPARQL-OWL queries. This is the largest set of competency questions with their linked queries to date, covering several ontologies of different type in different subject domains developed by different groups of question authors and ontology developers.

The ontology contains classes and properties corresponding to the core concepts of SOA. The formal OWL definitions are supplemented by natural language descriptions of the concepts, with graphic illustrations of the relations between them. For example: Work #1 Franz Schubert's Trout quintet * Expression #1 the composer's score * Expression #2 sound issued from the performance by the Amadeus Quartet and Hephzibah Menuhin on piano * Expression #3 sound issued from the performance by the Cleveland Quartet and Yo-Yo Ma on the cello * . . . .

The example pizza ontology includes the majority of the features of OWL. We use the pizza tutorial in 3 or four face to face tutorials each year with approximately 20 attendees in each tutorial. The written version is used by many, many people who start to use the Protege editor. I've also seen it used in courses taught by others The Ontology for Biomedical Investigations (OBI) is an ontology that provides terms with precisely defined meanings to describe all aspects of how investigations in the biological and medical domains are conducted. OBI re-uses ontologies that provide a representation of biomedical knowledge from the Open Biological and Biomedical Ontologies (OBO) project and adds the ability to describe how. In the example below, the Drug Class has a Python method for computing the per-tablet cost of a Drug, using two OWL Properties It is possible to associate a Python module with an OWL ontology. When Owlready loads the ontology, it will automatically import the Python module. This is done with the 'python_module' annotation, which should be set on the ontology itself. The value should be. Welcome. The movie ontology MO aims to provide a controlled vocabulary to semantically describe movie related concepts (e.g., Movie, Genre, Director, Actor) and the corresponding individuals (“Ice Age†, “Drama†, “Steven Spielberg†or “Johnny Depp†. The Web Ontology Language (OWL) is used to specify the MO ontology Description logics (DL) are a family of formal knowledge representation languages. Many DLs are more expressive than propositional logic but less expressive than first-order logic.In contrast to the latter, the core reasoning problems for DLs are (usually) decidable, and efficient decision procedures have been designed and implemented for these problems

In the following subsection ontology language, for example OWL. On the other hand, when we use an approach based on XSLT (i.e. XSLT principle) we do not need to change a UML tool, instead we just apply an XSLT on an output document of the UML tool. Accordingly, we can use well-defined XML/XSLT procedure that is shown in Figure 2. A UML tool (e.g. Poseidon for UML) can export an XMI document that an XSLT processor can use.

The concept of ontologies can be found everywhere, e.g. DbPedia is a triple store that replicates all of the facts that can be inferred from the information stored in the whole Wikipedia. If you look at the DbPedia ontology, you discover many common-sense relations we all know. For example, a person has children, but a car does not Ontologies and their OWL representations are used in oneM2M to provide syntactic and semantic interoperability between oneM2M and external systems. The oneM2M Base Ontology is described in TS-0012. It specifies the minimal ontology (i.e. mandating the least number of conventions) that is required such that other ontologies can be mapped into oneM2M. External organizations and companies can. Two classes in an ontology are disjoint if they cannot share an instance, regardless of how the classes are interpreted. For example: There can be no animal (or anything else) that can be both an Elephant and a Newt. If we said that the individual tiny is both a type of Elephant and a type of Newt and that Elephant and Newt are disjoint, then.

The aim of the research is to apply legal theories to a set of real legal documents, possibly defining OWL axioms in a Judicial Ontology Library (JudO) that provides a semantically expressive representation, and a solid ground for a (future) argumentation system that applies a defeasible subset of predicate logics. The JudO ontology library will be. We first motivate our effort with some sample tasks. In the central part of the paper we describe the upper ontology for services that we have developed, including its subontologies for profiles, processes, and groundings. The ontology is still evolving, and making connections to other development efforts, such as those building ontologies of time and resources. This paper accompanies OWL-S.

It shows the hierarchy of classes and subclasses for an object-entity , for eg ( computer ).It decribes subclass relationships , disjointness , constraints , information between objects OWL is a file format that stands for Web Ontology Language. In general, knowledge expressed in OWL format is computer-readable and can represent rich knowledge about resources (such as LOINC parts and LOINC terms) and the relationships between them. Since OWL is a standard format for representing ontological information, it is possible to query that knowledge, build visual representations.

Other Definitions of Ontology Include The Basic Formal Ontology (BFO) is a small, upper level ontology that is designed for use in supporting information retrieval, analysis and integration in scientific and other domains. BFO is a genuine upper ontology. Thus it does not contain physical, chemical, biological or other terms which would properly fall within the coverage domains of the special sciences. BFO is used by more than 250.
