The OpenCalais Web service can analyze text and provide rich semantic data for submitted text. With Yahoo! Pipes users can easily create custom RSS feeds. The Calais Pipes Service allows Yahoo! Pipes users to enrich their custom RSS feeds with semantic metadata.

IEML permet de représenter des concepts comme des ensembles de points dans un espace sémantique coordonné. Le métalangage a vocation à être utilisé par un protocole internet pour que naisse un espace sémantique commun sur le Web qui soit plus évolué et plus puissant que le Web sémantique actuellement préconisé par le WWW consortium, mais compatible avec celui-ci.

The Semantic Web brings with it the opportunities for users to get smarter search results, and for site owners to get more targeted traffic as users find what they really want. But these benefits don't just magically appear. This article leads you through the aspects of both information architecture and general infrastructure you need in place to truly take advantage of this burgeoning opportunity.

The Cypher™ beta release is the AI software program available which generates the .rdf (RDF graph) and .serql (SeRQL query) representation of a plain language input, allowing users to speak plain language to update and query databases. With robust definition languages, Cypher's grammar and lexicon can quickly and easily be extended to process highly complex sentences and phrases of any natural language, and can cover any vocabulary. Equipped with Cypher, programmers can now begin building next generation semantic web applications that harness what is already the most widely used tool known to man - natural language.

Triplify provides a building block for the “semantification” of Web applications. Triplify is a small plugin for Web applications, which reveals the semantic structures encoded in relational databases by making database content available as RDF, JSON or Linked Data.

The Bibliographic Ontology Specification provides main concepts and properties for describing citations and bibliographic references (i.e. quotes, books, articles, etc) on the Semantic Web.

TechCrunch and Search Engine Land are reporting this morning that Yahoo! will now be indexing Semantic Web and Microformats markup from around the web and will use that information to display more structured search results.

MOAT (Meaning Of A Tag) provides a Semantic Web framework to publish semantically-annotated content from free-tagging. While tags are widely used in Web 2.0 services, their lack of machine-understandable meaning can be a problem for information retrieval, especially when people use tags that can have different meanings depending on the context. MOAT aims to solve this by providing a way for users to define meaning(s) of their tag(s) using URIs of Semantic Web resources (such as URIs from dbpedia, geonames … or any knowledge base), and then annotate content with those URIs rather than free-text tags, leveraging content into Semantic Web, by linking data together. Moreover, tag meanings can be shared between people, providing an architecture of participation to define and exchange potential meanings of tags within a community of users. To achieve this goal, MOAT relies on an architecture that can be deployed for any organisation or community and that involves a lightweight ontology, a MOAT server, and some third-party clients .

tutorial on RDFa

One of the technical difficulties that we outlined was the bottom-up nature of the classic semantic web approach. Specifically, each web site needs to annotate information in RDF, OWL, etc. in order for computers to be able to "understand" it.

The purpose of this post is to highlight 10 Semantic Apps. We're not touting this as a 'Top 10', because there is no way to rank these apps at this point - many are still non-public apps, e.g. in private beta. It reflects the nascent status of this sector, even though people like Hillis and Spivack have been working on their apps for years now.

Today, we present a screencast exhibiting Protégé — a free, open source ontology editor and knowledge-base framework developed by Stanford Center for Biomedical Informatics Research at the Stanford University School of Medicine. In this screencast, we show you how to develop a useful Semantic Web-ready application in just minutes. You will learn how to model a very simple ontology in OWL (the Web Ontology Language).

Le terme html sémantique peut intimider par sa longueur et donne une fausse mauvaise impression de sa simplicité, de sa bonne adoption par les designers web modernes, et les avantages qu'il possède vont bien au delà de développer pour le web comme il faut en utilisant un balisage sémantique. Nous avons besoin d'un terme court et facile à retenir qui capte l'essence du concept, et soit facile à conjuguer. CHIC a été proposé par Kevin Marks et la déclinaison de l'acronyme Code HTML Intrinsèquement Classe proposée par Stéphane Gigandet colle bien au sens du 'POSH'.

Tim Berners Lee a crée une nouvelle discipline appelé “Web Science” (au M.I.T.) qui se compose de professeurs, de scientifiques, de sociologues et d’entrepreneurs du monde entier.

I often wonder how the Semantic Web will affect game development, and how games may take advantage of Semantic Web technologies. I've searched high and low (on Google) and haven't found a single written piece on people's ideas of the Semantic Web and video games so I will describe my own, as well as provide some visuals to give you a clear picture.

Operator leverages microformats and other semantic data that are already available on many web pages to provide new ways to interact with web services.

A l'occasion de la nouvelle version de Dbpedia, je me suis remis au boulot et j'ai mis au point quelques exemples qui, je l'espère, montreront tout l'intérêt de disposer de données structurées, disponibles sous une forme normalisée, RDF, et interrogeable via un langage de requête et un protocole normalisé, SPARQL. Bref, montrer l'intérêt des technologies du Web sémantique.

dbpedia.org is a community effort to extract structured information from Wikipedia and to make this information available on the Web. dbpedia allows you to ask sophisticated queries against Wikipedia and to link other datasets on the Web to Wikipedia data.

The Semantic Web is a set of technologies which are designed to enable a particular vision for the future of the Web — a future in which all knowledge exists on the Web in a format that software applications can understand and reason about. By making knowledge more accessible to software, software will essentially become able to understand knowledge, think about knowledge, and create new knowledge. In other words, software will be able to be more intelligent — not as intelligent as humans perhaps, but more intelligent than say, your word processor is today.

Full of tools for for Semantic Web

This is ontoworld.org, the wiki for the Semantic Web community. Our mission is to provide a knowledge repository and platform for advertising events, spreading news, and announcing new developments. It is a wiki: everybody can quickly edit its content, even without logging in. So look around and participate!

Swoogle est un moteur de recherche pour le moins intéressant car il recherche des ontologies. La classification des méta données revêt un enjeux particulièrement important et ce moteur de recherche est une bonne initiative, surtout pour ceux qui creusent le sujet et dévelopent de nouvelles applications.

Vous ne connaissez pas les microformats ? Bon. Ca va être un peu technique a expliquer. Pour Frédéric Cavazza, consultant, le principal intérêt est de “rendre exploitable par des robots du contenu à la base crée pour des humains. Exploitable veut dire qu’à partir d’une requête structurée il est possible de rapatrier des informations précises. Par exemple « va sur le site XX pour parcourir sa liste de liens et me rapatrier tous les sites dont les auteurs se connaissent personnellement ». Ça n’a l’air de rien, mais ce type de requête structurée peut vous éviter d’avoir à investir des milliards de dollars dans un algorithme d’indexation plus performant que celui de Google.”
