Developers Guide to Semantic Web Toolkits for different Programming Languages
Abstract This guide collects links to Semantic Web toolkits for different programming languages and gives an overview about the features of each toolkit, the strength of the development effort and the toolkit's user community. Our current evaluation results are found below. The information was collected by us from the websites of the toolkits or was sent to us by the developers of the toolkits. Thanks a lot to all toolkit developers and users who helped to create this guide.
Triple Stores
Semantic MediaWiki (SMW) is a free, open-source extension to MediaWiki – the wiki software that powers Wikipedia – that lets you store and query data within the wiki's pages. Semantic MediaWiki is also a full-fledged framework, in conjunction with many spinoff extensions, that can turn a wiki into a powerful and flexible “collaborative database”. All data created within SMW can easily be published via the Semantic Web , allowing other systems to use this data seamlessly. Found errors or omissions?

Defining the Semantic Web in a Few Sentences - semanticweb.com
A Quora user posed this challenge to the network: “How do you explain semantic web to a nine-year old child in one sentence?” The challenge was followed by a quote from Albert Einstein: “If you can’t explain it to a six year old, you don’t understand it yourself.” Some of the best responses so far include, “A web where computers better understand the real meaning of the words we use to communicate with them.” “Hi Timmy, the web is like one giant big book written by a lot of people. And the semantic web is another book describing how the first book should be read.” And, “Semantic web is like the magic mirror in Shrek – you ask it, ‘Can I go to a pool?’
Setting Gold Standards for the Semantic Web - semanticweb.com
A new article out of AI 3 discusses the need for so-called “gold standards” in the semantic web and examines several possible gold standards. As the article puts it, “The types of gold standards useful to the semantic Web are similar to those useful to our analogy of human languages. We need guidance on structure (syntax and grammar), plus reference vocabularies that encompass the scope of the semantic Web (that is, everything).” The gold standards that the author, Mike Bergman suggests are RDF, RDFS and OWL (building blocks for languages); Wikipedia (a “standard reference vocabulary of things, concepts, and entities”); WordNet (“lexical language references as an aid to natural language processing”); and UMBEL (“the structural reference for the connectedness of things”). The article goes on to discuss each potential gold standard in detail. The article insists, “The need for gold standards for the semantic Web is particularly acute.
Un article de Wikipédia, l'encyclopédie libre. En philosophie , l' ontologie (de onto- , tiré du grec ὤν , ὄντος « étant », participe présent du verbe εἰμί « être ») est l'étude de l' être en tant qu' être , c'est-à-dire l'étude des propriétés générales de ce qui existe. Par analogie, le terme est repris en informatique et en science de l'information , où une ontologie est l'ensemble structuré des termes et concepts représentant le sens d'un champ d'informations, que ce soit par les métadonnées d'un espace de noms , ou les éléments d'un domaine de connaissances. L'ontologie constitue en soi un modèle de données représentatif d'un ensemble de concepts dans un domaine , ainsi que des relations entre ces concepts. Elle est employée pour raisonner à propos des objets du domaine concerné. Plus simplement, on peut aussi dire que l'« ontologie est aux données ce que la grammaire est au langage ».

Moteur d'inférence - Wikipédia
Un article de Wikipédia, l'encyclopédie libre. Un moteur d'inférence (du verbe « inférer » qui signifie « déduire ») est un logiciel correspondant à un algorithme de simulation des raisonnements déductifs . Un moteur d'inférence permet aux systèmes experts de conduire des raisonnements logiques et de dériver des conclusions à partir d'une base de faits et d'une base de connaissances . Les moteurs d'inférences peuvent implémenter :
