  • Ontology (information science)

    In computer science and information science, an ontology formally represents knowledge as a hierarchy of concepts within a domain, using a shared vocabulary to denote the types, properties and interrelationships of those concepts.Ontologies are the structural frameworks for organizing information and are used in artificial intelligence, the Semantic Web, systems engineering, software engineering, biomedical informatics, library science, enterprise bookmarking, and information architecture as a form of knowledge representation about the world or some part of it.

  • Linked Open Data

    Linked Open Data (LOD) bezeichnet im World Wide Web frei verfügbare Daten, die per Uniform Resource Identifier (URI) identifiziert sind und darüber direkt per HTTP abgerufen werden können und ebenfalls per URI auf andere Daten verweisen. Idealerweise werden zur Kodierung und Verlinkung der Daten das Resource Description Framework (RDF) und darauf aufbauende Standards wie SPARQL und die Web Ontology Language (OWL) verwendet, so dass Linked Open Data gleichzeitig Teil des Semantic Web ist.

  • Formal ontology

    In philosophy, the term formal ontology is used to refer to an ontology defined by axioms in a formal language with the goal to provide an unbiased (domain- and application-independent) view on reality, which can help the modeler of domain- or application-specific ontologies (information science) to avoid possibly erroneous ontological assumptions encountered in modeling large-scale ontologies.By maintaining an independent view on reality a formal (upper level) ontology gains the following properties:indefinite expandability:the ontology remains consistent with increasing content.content and context independence:any kind of 'concept' can find its place.accommodate different levels of granularity.Theories on how to conceptualize reality date back as far as Plato and Aristotle.

  • Adaptive Hypermedia Systeme

    Adaptive Hypertext und Hypermedia Systeme (auch AH Systeme) sind Systeme, die Eigenschaften von Benutzern in ein Benutzermodell aufnehmen und durch Anwendung des Modells ihre sichtbaren Inhaltsobjekte benutzerspezifisch anpassen.

  • Semantic search

    Semantic search seeks to improve search accuracy by understanding searcher intent and the contextual meaning of terms as they appear in the searchable dataspace, whether on the Web or within a closed system, to generate more relevant results. Author Seth Grimes lists "11 approaches that join semantics to search", and Hildebrand et al. provide an overview that lists semantic search systems and identifies other uses of semantics in the search process.

  • Longboarding

    Longboarding is the act of riding on a longboard skateboard. A longboard is greater in size (both length and width) than its smaller counterpart, the skateboard, and has more stability, traction and durability due to lower wheel durometers. Many, but not all longboards, use trucks (axles) that contain different geometric parameters than a skateboard as well. These factors and their variation have given way to a variety of disciplines, functions and purposes for a longboard.

  • VW Polo II

    Der Polo 86C (oder Polo II, ugs. 2er Polo) ist ein Fahrzeugmodell von Volkswagen, welches von Oktober 1981 bis Juli 1994 in den Werken Wolfsburg, Pamplona (Spanien) und zuletzt auch in Mosel insgesamt rund 1,7 Mio. Mal gefertigt wurde. Es gab ihn als dreitüriges Steil- oder Schrägheck (Coupé), mit Vier- oder Fünfgang-Handschaltung, Frontantrieb und vorne quer eingebauten Benzinmotoren von 29 kW (40 PS) bis 85 kW (115 PS) sowie Dieselmotoren mit 33 kW (45 PS) und 35 kW (48 PS).

  • Do it yourself

    Do it yourself (DIY) is the method of building, modifying, or repairing something without the aid of experts or professionals. Academic research describes DIY as behaviors where "individuals engage raw and semi-raw materials and component parts to produce, transform, or reconstruct material possessions, including those drawn from the natural environment (e.g., landscaping)".
