In this e-book, Jos de Bruijn and his coauthors lay the principles for realizing the necessities that form the outline of many of the elements with regards to Semantic net prone, corresponding to the static historical past wisdom within the type of ontologies, the practical description of the provider, and the behavioral description of the carrier. They introduce the internet carrier Modeling Language (WSML), which gives potential for describing the performance and behaviour of internet prone, in addition to the underlying company wisdom, within the kind of ontologies, with a conceptual grounding within the net carrier Modeling Ontology.

Academic and commercial researchers in addition to execs will discover a finished assessment of the strategies and demanding situations within the zone of Semantic internet companies, the internet prone Modeling Language and its relation to the internet prone Modeling Ontology, and an in-depth remedy of either allowing applied sciences and theoretical foundations.

The usage of ofType and impliesType correspond with the usage in attribute definitions. Namely, parameter definitions with the ofType keyword are used to check the type of parameter values, whereas parameter definitions with the impliesType keyword are used to infer concept membership of parameter values. The following is an example of a relation. relation stageNameContributor(ofType {}, ofType xsd#string) annotations dc#description hasValue ”Relation between (the stage names of) contributors to media items and the titles of these items .

The logical expression in which the variable occurs is the scope of quantification), unless indicated otherwise, through the sharedVariables construct (see the next section) and unless the logical expression occurs in a non-functional property, in which case the variables are interpreted as parameters, that may be replaced with ground terms. , IRIs or data values), variables, or constructed terms of the form f(t1 , . . , tn ). , p(t1 , . . , tn ). Besides the usual atoms, WSML has a special kind of atoms, called molecules, which are used to capture information about concepts, instances, attributes and attribute values.

Variables that occur in the head or in a negative body literal do not need to occur in a positive body literal. The logical syntax of WSML-Full is equivalent to the general logical expression syntax of WSML and allows the full expressiveness of all other WSML variants. The separation between conceptual and logical modeling allows for easy adoption by non-experts, since the conceptual syntax does not require expert knowledge in logical modeling, whereas complex logical expressions require more familiarity and training with the language.
