Web ontology language

The technological foundations of this vision currently consist of extensible Markup Language (XML) [76], XML Schema [77], the Resource Description Framework (RDF) [61], RDF Schema [62], and the Web Ontology Language [63]. These technologies are interdependent and can thus be arranged in the form of a semantic layer cake (Fig. 9). [Pg.121]

Introduction of XML formats was a very important step toward better intercomputer communication, but it is not a miraculous solution to all problems. Not every possible relation is easily expressed in XML (Wang et al. 2005), so specifications usually contain many implicit assumptions that are not properly formalized. The Resource Description Framework (RDF) provides a very powerful yet simple model for this formalization (Manola and Miller 2004). In this framework, any information is transformed to basic units called triplets that are combined to map the available information. This unifying mechanism can be used to express hierarchical vocabularies for domain knowledge description, as in RDF Schema (Brickley and Guha 2004) or its extension, Web Ontology Language (OWL) (Smith et al. 2004), both standardized by the W3C. [Pg.116]

For similar reasons as for the Process Ontology (Subsect. 2.4.6), OWL ( Web Ontology Language, [546]) has been chosen as implementation language. That way, the integration of the Decision Ontology with the other application domain models is simplified, and description logics reasoners such as RacerPro [918] can be used for consistency checks. [Pg.157]

As a prerequisite for a formal integration, all four submodels must be represented in a common modeling language. The Web Ontology Language OWL... [Pg.169]

The Web Ontology Language (OWL) ° was introduced as a more expressive ontology language than RDF(S). Since 2012, W3C recommends the use of OWL 2, an extended and improved version of OWL 1. OWL 2 enhances the expressivity of RDF(S) in several ways. We provide a few examples of OWL 2 constructs that are used in the chapters of the book, but refrain from a complete introduction to this language. [Pg.67]

The Web Ontology Language (OWL) is an ontology language where one can declare relations between concepts such as equivalence, subsumption, etc., and allows one to infer additional information about instances by reasoning over the properties of classes and relations. Although one can define one-to-one correspondence... [Pg.149]

The current knowledge representation standard used by most ontologies is the Web Ontology Language (OWL), which is an ontology language for the Semantic Web with formally defined meaning (World Wide Web Consortium 2012). There are several reasons why we chose to use a Frame formalism and not OWL, which we enumerate below. [Pg.302]
