Wikidata
Wikidata is a collaboratively edited multilingual knowledge graph hosted by the Wikimedia Foundation. It is a common source of open data that Wikimedia projects such as Wikipedia, and anyone else, can use under the CC0 public domain license. Wikidata is a wiki powered by the software MediaWiki, and is also powered by the set of knowledge graph MediaWiki extensions known as Wikibase. Concept Wikidata is a document-oriented database, focused on items, which represent any kind of topic, concept, or object. Each item is allocated a unique, persistent identifier, a positive integer prefixed with the upper-case letter Q, known as a "QID". This enables the basic information required to identify the topic that the item covers to be translated without favouring any language. Examples of items include , , , , and . Item labels need not be unique. For example, there are two items named "Elvis Presley": , which represents the American singer and actor, and , which represents his s ...

MediaWiki
MediaWiki is a free and open-source wiki software. It is used on Wikipedia and almost all other Wikimedia websites, including Wiktionary, Wikimedia Commons and Wikidata; these sites define a large part of the requirement set for MediaWiki. It was developed for use on Wikipedia in 2002, and given the name "MediaWiki" in 2003. MediaWiki was originally developed by Magnus Manske and improved by Lee Daniel Crocker. Magnus Manske's announcement of "PHP Wikipedia", wikipedia-l, August 24, 2001 Its development has since then been coordinated by the Wikimedia Foundation. MediaWiki is written in the PHP programming language and stores all text content into a database. The software is optimized to efficiently handle large projects, which can have terabytes of content and hundreds of thousands of views per second. Because Wikipedia is one of the world's largest websites, achieving scalability through multiple layers of caching and database replication has been a major concern for de ...

Wikimedia Foundation
The Wikimedia Foundation, Inc., or Wikimedia for short and abbreviated as WMF, is an American 501(c)(3) nonprofit organization headquartered in San Francisco, California and registered as a charitable foundation under local laws. Best known as the hosting platform for Wikipedia, a crowdsourced online encyclopedia, it also hosts other related projects and MediaWiki, a wiki software. The Wikimedia Foundation was established in 2003 in St. Petersburg, Florida, by Jimmy Wales as a nonprofit way to fund Wikipedia, Wiktionary, and other crowdsourced wiki projects that had until then been hosted by Bomis, Wales's for-profit company. The Foundation finances itself mainly through millions of small donations from Wikipedia readers, collected through email campaigns and annual fundraising banners placed on Wikipedia and its sister projects. These are complemented by grants from philanthropic organizations and tech companies, and starting in 2022, by services income from Wikimedia E ...

Wikipedia
Wikipedia is a multilingual free online encyclopedia written and maintained by a community of volunteers, known as Wikipedians, through open collaboration and using a wiki-based editing system. Wikipedia is the largest and most-read reference work in history. It is consistently one of the 10 most popular websites ranked by Similarweb and formerly Alexa; Wikipedia was ranked the 5th most popular site in the world. It is hosted by the Wikimedia Foundation, an American non-profit organization funded mainly through donations. Wikipedia was launched by Jimmy Wales and Larry Sanger on January 15, 2001. Sanger coined its name as a blend of ''wiki'' and '' encyclopedia''. Wales was influenced by the " spontaneous order" ideas associated with Friedrich Hayek and the Austrian School of economics after being exposed to these ideas by the libertarian economist Mark Thornton. Initially available only in English, versions in other languages were quickly developed. Its combin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wikibase
Wikibase is a set of MediaWiki extensions for working with versioned semi-structured data in a central repository based upon JSON instead of the unstructured data of MediaWiki wikitext. Its primary components are the ''Wikibase Repository'', an extension for storing and managing data, and the ''Wikibase Client'' which allows for the retrieval and embedding of structured data from a wikibase repository. Wikibase was developed for and is used by Wikidata. The data model for Wikibase links consists of "entities" which include individual "items", labels or identifier to describe them (potentially in multiple languages), and semantic statements that attribute "properties" to the item. These properties may either be other items within the database, or textual information. Wikibase has a JavaScript-based user interface, and provides exports of all or subsets of data in many formats. Projects using it include Wikidata, Europeana's Eagle Project, Lingua Libre, and the OpenStreetMap wiki. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

ShEx
Shape Expressions (ShEx) is a data modelling language for validating and describing a Resource Description Framework (RDF). It was proposed at the 2012 RDF Validation Workshop as a high-level, concise language for RDF validation. The shapes can be defined in a human-friendly compact syntax called ShExC or using any RDF serialization formats like JSON-LD or Turtle. ShEx expressions can be used both to describe RDF and to automatically check the conformance of RDF data. The syntax of ShEx is similar to Turtle and SPARQL while the semantics is inspired by regular expression languages like RelaxNG. Example PREFIX : PREFIX schema: PREFIX xsd: :Person The previous example declares that nodes conforming to shape Person must have one property schema:name with a string value and zero or more properties schema:knows whose values must conform with shape Person. Implementations shex.js JavaScript shaclex Scala library with support for Jena (framework) and RDF4J PyShEx ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Knowledge Base
A knowledge base (KB) is a technology used to store complex structured and unstructured information used by a computer system. The initial use of the term was in connection with expert systems, which were the first knowledge-based systems. Original usage of the term The original use of the term knowledge base was to describe one of the two sub-systems of an expert system. A knowledge-based system consists of a knowledge-base representing facts about the world and ways of reasoning about those facts to deduce new facts or highlight inconsistencies. Properties The term "knowledge-base" was coined to distinguish this form of knowledge store from the more common and widely used term ''database''. During the 1970s, virtually all large management information systems stored their data in some type of hierarchical or relational database. At this point in the history of information technology, the distinction between a database and a knowledge-base was clear and unambiguous. A databas ...

Open Data
Open data is data that is openly accessible, exploitable, editable and shared by anyone for any purpose. Open data is licensed under an open license. The goals of the open data movement are similar to those of other "open(-source)" movements such as open-source software, hardware, open content, open specifications, open education, open educational resources, open government, open knowledge, open access, open science, and the open web. The growth of the open data movement is paralleled by a rise in intellectual property rights. The philosophy behind open data has been long established (for example in the Mertonian tradition of science), but the term "open data" itself is recent, gaining popularity with the rise of the Internet and World Wide Web and, especially, with the launch of open-data government initiatives such as Data.gov, Data.gov.uk and Data.gov.in. Open data can be linked data - referred to as linked open data. One of the most important forms of open data is o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Knowledge Graph
The Google Knowledge Graph is a knowledge base from which Google serves relevant information in an infobox beside its search results. This allows the user to see the answer in a glance. The data is generated automatically from a variety of sources, covering places, people, businesses, and more. The information covered by Google's Knowledge Graph grew quickly after launch, tripling its size within seven months (covering 570 million entities and 18 billion facts). By mid-2016, Google reported that it held 70 billion facts and answered "roughly one-third" of the 100 billion monthly searches they handled. By May 2020, this had grown to 500 billion facts on 5 billion entities. There is no official documentation of how the Google Knowledge Graph is implemented. According to Google, its information is retrieved from many sources, including the ''CIA World Factbook'' and Wikipedia. It is used to answer direct spoken questions in Google Assistant and Google Home voice queries. It ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
