Semantic Web Ontology

Ontologies in the Semantic Web Terms such as Ontology and Semantic Web are still a new territory for many. However, in today's information society, which is characterized by digitalization and automation, these terms are gaining more and more importance The W3C Web Ontology Language (OWL) is a Semantic Web language designed to represent rich and complex knowledge about things, groups of things, and relations between things

As one of the building blocks of Semantic Technology, ontologies are part of the W3C standards stack for the Semantic Web. They provide users with the necessary structure to link one piece of information to other pieces of information on the Web of Linked Data Ontologien haben mit der Idee des semantischen Webs einen Aufschwung erfahren und sind damit Teil der Wissensrepräsentation im Teilgebiet Künstliche Intelligenz. Im Unterschied zu einer Taxonomie, die nur eine hierarchische Unter gliederung bildet, stellt eine Ontologie ein Netzwerk von Informationen mit logischen Relationen dar Das Semantic Web beschreibt dazu konzeptionell einen Giant Global Graph (engl. ‚gigantischer globaler Graph '). Dabei werden sämtliche Dinge von Interesse identifiziert und mit einer eindeutigen Adresse versehen als Knoten angelegt, die wiederum durch Kanten (ebenfalls jeweils eindeutig benannt) miteinander verbunden sind I have been attempting to keep up to date with up to date topics in computer science, and I keep reading about the semantic web. From my understanding, the semantic web means the following: 1

OWL - Semantic Web Standard

  1. The Semantic Web is an extension of the World Wide Web through standards set by the World Wide Web Consortium (W3C). The goal of the Semantic Web is to make Internet data machine-readable. To enable the encoding of semantics with the data, technologies such as Resource Description Framework (RDF) and Web Ontology Language (OWL) are used
  2. The OWL 2 Web Ontology Language, informally OWL 2, is an ontology language for the Semantic Web with formally defined meaning. OWL 2 ontologies provide classes, properties, individuals, and data values and are stored as Semantic Web documents
  3. Ontology is a body of knowledge describing some domain, typically common sense knowledge domain. The definition 1 is the meaning in philosophy as we have discussed above, however it has many implications for the AI purposes. The second definition is generally accepted as a definition of what an ontology is for the AI community. The last third definition views an ontology as an inner body of knowledge, not as the way to describe the knowledge
  4. In a Semantic Web context, ontologies are a main vehicle for data integration, sharing, and discovery, and a driving idea is that ontologies themselves should be reusable by others. The DARPA DAML program ended in 2006, and subsequently there were few if any large-scale funding lines for fundamental Semantic Web research in the U.S

KAON2 also supports the so-called DL-safe subset of the Semantic Web Rule Language (SWRL). The restriction to the DL-subset has been chosen to make reasoning decidable.

Initiatives on linked open data for collaborative maintenance and evolution of community knowledge based on ontologies emerge, and the first semantic applications of Web-based ontology technology are successfully positioned in areas like semantic search, information integration, or Web community portals •Browser tools render information for human consumption •Web was invented by Tim Berners-Lee(amongst others), a physicist working at CERN •His vision of the Web was much more ambitious than the reality of the existing (syntactic) Web: •This vision of the Web has become known as the Semantic Web

The figure illustrates the architecture of this framework. There are two basic components, the Ontology Backend and the Graph Analysis component. The Ontology Backend provides basic functionality to load and parse RDF and OWL documents. It allows to access different parts within the document, e.g. subject, predicate and objects of RDF statements Semantic Web, Web 3.0, shared understanding, shared semantic annotation, tree of Porphyry, ontology,wordnet, mesh,rdf, iri, description logics, DLs, Owl, WebP Semantic Web Project ###Creating and querying an ontology The goal of this project is to define, populate and query an ontology about Movies.

What is Ontology - Introduction to ontologies and semantic

The Semantic Web is well recognized as an effective infrastructure to enhance visibility of knowledge on the Web. The core of the Semantic Web is ontology, which is used to explicitly represent our conceptualizations. Ontology engineering in the Semantic Web is primarily supported by languages such as RDF, RDFS and OWL. This chapter discusses the requirements of ontologies in the context of th Semantic web and ontology represent information which are machine processable and understand the semantics present among the entities. Ontology can be represented as Knowledge Organization and. Among all essential components of the semantic web, ontology plays the most important role since it makes the extraction and formalization of semantics possible. There are several approaches for building ontologies as discussed in [1, 2]. The concepts in ontologies are represented in natural language words. Yet meaning an

This further evolution is known as Semantic WoT and relies on a WoT implementation crafted on the technologies proposed by the Semantic Web stack. This article presents a working implementation of the WoT declined in its Semantic flavor through the adoption of a shared ontology for describing devices. In addition to that, the ontology includes patterns for dynamic interactions between devices, and therefore we define it as dynamic ontology. A practical example will give a proof of concept. Prominent Semantic Web Standards include RDF, which is used to describe relationships between entities, and OWL, the Ontology Web Language.[3] Triple Store databases store semantic relationship data, and are named for the triple subject, predicate, object structure defined by RDF. [4] Semantic Web services provide semantically tagged data. They are valuable in exposing existin this problem is to find a single Semantic Web ontology such that the whole set of words can all be matched by the terms it defines, where a matching term has a local name which is either the same as the matched word or a synonym of it.

One of the core challenges for the Semantic Web is the aspec Ontologies are often seen as basic building blocks for the Semantic Web, as they provide a reusable piece of knowledge about a specific domain. However, those pieces of knowledge are not static, but evolve over time. Domain changes, adaptations to different tasks, or changes in the conceptualization require modifications of the ontology. The evolution of ontologies causes operability problems. the Web—known as the Semantic Web—which has been defined as the conceptual structuring of the Web in an explicit machine-readable way. 1 This definition does not differ too much from the one used for defin-ing an ontology:An ontology is an explicit,machine-readable specification of a shared conceptualization.
