The Web Ontology Language (OWL) is a family of knowledge representation languages for authoring ontologies.Ontologies are a formal way to describe taxonomies and classification networks, essentially defining the structure of knowledge for various domains: the nouns representing classes of objects and the verbs representing relations between the objects.
The World Wide Web Consortium (W3C) Incubator Group for Uncertainty Reasoning for the World Wide Web [27] (URW3-XG) final report lumps these problems together under the single heading of "uncertainty". [28] Many of the techniques mentioned here will require extensions to the Web Ontology Language (OWL) for example to annotate conditional ...
Since its publication as a W3C Community report in 2016, [2] it serves as ``a de facto standard to represent ontology-lexica on the Web´´. [3] OntoLex-Lemon is a revision of the Lemon vocabulary originally proposed by McCrae et al. (2011). [4] Fig. 1. OntoLex-Lemon core model. The core elements of OntoLex-Lemon, shown in Fig. 1, are:
Ontology engineering (also called ontology building) is a set of tasks related to the development of ontologies for a particular domain. [30] It is a subfield of knowledge engineering that studies the ontology development process, the ontology life cycle, the methods and methodologies for building ontologies, and the tools and languages that ...
The Semantic Web is a collaborative movement led by international standards body the World Wide Web Consortium (W3C). [1] The standard promotes common data formats on the World Wide Web . By encouraging the inclusion of semantic content in web pages , the Semantic Web aims at converting the current web, dominated by unstructured and semi ...
The first version [1] [4] was published by the World-Wide Web Consortium (W3C) in April 1998, and the final W3C recommendation was released in February 2014. [3] Many RDFS components are included in the more expressive Web Ontology Language (OWL).
It was then picked up in the joint OGC and W3C Spatial Data on the Web Working Group and published as a W3C Recommendation. [4] The Semantic Sensor Network (SSN) ontology enables expressive representation of sensor observations, sampling, and actuation. The SSN ontology is encoded in the Web Ontology Language (OWL2). A number of projects have ...
The PROV standard defines a data model, serializations, and definitions to support the interchange of provenance information on the Web. [1] Here provenance includes all "information about entities, activities, and people involved in producing a piece of data or thing, which can be used to form assessments about its quality, reliability or trustworthiness".
