  • Semantic Web

    The Semantic Web is an extension of the Web through standards by the World Wide Web Consortium (W3C). The standards promote common data formats and exchange protocols on the Web, most fundamentally the Resource Description Framework (RDF).According to the W3C, "The Semantic Web provides a common framework that allows data to be shared and reused across application, enterprise, and community boundaries".

  • Ontology (information science)

    In computer science and information science, an ontology is a formal naming and definition of the types, properties, and interrelationships of the entities that really or fundamentally exist for a particular domain of discourse.

  • Data cleansing

    Data cleansing, data cleaning or data scrubbing is the process of detecting and correcting (or removing) corrupt or inaccurate records from a record set, table, or database. Used mainly in databases, the term refers to identifying incomplete, incorrect, inaccurate, irrelevant, etc. parts of the data and then replacing, modifying, or deleting this dirty data or coarse data.After cleansing, a data set will be consistent with other similar data sets in the system.

  • 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.

  • Knowledge management

    Knowledge management (KM) is the process of capturing, developing, sharing, and effectively using organizational knowledge. It refers to a multi-disciplined approach to achieving organizational objectives by making the best use of knowledge.An established discipline since 1991 (see Nonaka 1991), KM includes courses taught in the fields of business administration, information systems, management, and library and information sciences.

  • Adaptive hypermedia

    Adaptive Hypermedia is a disputed research field where hypermedia is made adaptive according to a user model.In contrast to traditional e-learning/electronic learning, e-business, and e-government systems, whereby all users are offered or even directed a standard series of hyperlinks, adaptive hypermedia (AH) tailors what the user sees to a model of the user's goals, preferences and knowledge.

  • 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. Semantic search systems consider various points including context of search, location, intent, variation of words, synonyms, generalized and specialized queries, concept matching and natural language queries to provide relevant search results.

  • 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 larger wheel size and lower wheel durometers. Many, but not all longboards, use trucks (axles) that contain different geometric parameters than a skateboard as well.

  • Do it yourself

    Do it yourself, also known as 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)".
