Understands the role of formally declared domains and ranges for inferencing. – Linked Data for Professional Education https://ld4pe.dublincore.org Learning resources tagged by competency Thu, 19 Nov 2020 14:45:03 +0000 en-US hourly 1 https://wordpress.org/?v=4.9.16 OWL 2 Web Ontology Language Primer (Second Edition) https://ld4pe.dublincore.org/learning_resource/owl-2-web-ontology-language-primer-second-edition/ Thu, 18 May 2017 07:03:04 +0000 https://ld4pe.dublincore.org/learning_resource/owl-2-web-ontology-language-primer-second-edition/ This primer provides an approachable introduction to OWL 2, including orientation for those coming from other disciplines, a running example showing how the language can be used to represent first simple information and then more complex information, how it manages ontologies, and finally the distinctions between its various "flavors".

RDF Homework Exercises https://ld4pe.dublincore.org/learning_resource/rdf-homework-exercises/ Sat, 21 Jan 2017 06:46:41 +0000 https://ld4pe.dublincore.org/learning_resource/rdf-homework-exercises/ This document contains several "written" and "electronic" homework questions originally from the course "Semantic Web Topics" at LeHigh University. They include: Translating an RDF Graph into the Turtle syntax; Using the RDFS entailment rules determine what triples can be inferred from an RDF Graph; Explain the advantage of using multiple rdfs:range statements over using the union of the individual ranges to determine the actual range; Draw the equivalent graph when given an RDF document written in XML; Write the equivalent RDF/XML for a series of online references; Using Jena, write a class object that can read in an RDF file that was written using a specific vocabulary and output a list of the publications, one per line.

OOPS!: Ontology Pitfall Scanner https://ld4pe.dublincore.org/learning_resource/oops-ontology-pitfall-scanner/ Sun, 15 Jan 2017 06:46:04 +0000 https://ld4pe.dublincore.org/learning_resource/oops-ontology-pitfall-scanner/ This tool helps to detect some of the most common pitfalls appearing when developing ontologies. The user enters a URI or paste an OWL document into a text field and a list of pitfalls( and the elements of the ontology where they appear) is displayed. For example: OOPS will detect if the domain or range of a relationship is defined as the intersection of two or more classes. This warning could avoid reasoning problems in case those classes could not share instances.

OOPS!: Catalogue of Common Pitfalls https://ld4pe.dublincore.org/learning_resource/oops-catalogue-of-common-pitfalls/ Sun, 15 Jan 2017 06:46:04 +0000 https://ld4pe.dublincore.org/learning_resource/oops-catalogue-of-common-pitfalls/ This catalogue of the most common pitfalls appearing when developing ontologies is part of the documentation for the OOPS! (OntOlogy Pitfall Scanner). The catalogue includes pitfalls which depend on the domain being modeled or the requirements specified for each particular ontology. Pitfalls that fall into these categories cannot be detected by the OOPS tool, and the user should manually check their ontology for these issues. As such, this catalogue serves as a useful guide for anyone who is developing an ontology, regardless of the tools they are using.

Protege: How To Define Property Types and Axioms https://ld4pe.dublincore.org/learning_resource/protege-how-to-define-property-types-and-axioms/ Wed, 11 Jan 2017 06:45:38 +0000 https://ld4pe.dublincore.org/learning_resource/protege-how-to-define-property-types-and-axioms/ This video is about defining property types and axioms using Protégé, a free, open-source ontology editor and framework. Although the video deals with one specific tool, it lends insight into the thought process of building out an ontology from scratch.

Protege: How To Add Individuals https://ld4pe.dublincore.org/learning_resource/protege-how-to-add-individuals/ Wed, 11 Jan 2017 06:45:37 +0000 https://ld4pe.dublincore.org/learning_resource/protege-how-to-add-individuals/ This video is about adding individuals to an ontology which was previously created using Protégé, a free, open-source ontology editor and framework. Although the video deals with one specific tool, it lends insight into the thought process of building out an ontology from scratch. Discusses object property assertions and shows an example of how the tool's built-in reasoner can detect inconsistencies in the ontology.

This is demonstrated with Protégé, a free, open-source ontology editor and framework. Although the video deals with one specific tool, it lends insight into the thought process of building out an ontology from scratch.

Also shows how to add data property assertions to further describe these individuals, reminding the users that the proper datatype must be used for each property.
