Comment le web de données change-t-il la nature de la toile ? En rendant les contenus du web lisibles par les machines, le web sémantique bouleverse notre univers informationnel et ouvre de nouvelles opportunités propres à redéfinir la nature du Web : d’un web de document à un web de données. (ce billet est issue d’une note de synthèse, réalisée dans le cadre de mes activités universitaires. Il s’agit d’un bilan de lecture autour du web de données. Il m’a semblé intéressant de le republier ici pour solliciter l’avis des connaisseurs de ce sujet, et ouvrir le débat) 1. Croissance exponentielle du volume et de la valeur des données : le terreau d’éclosion du web de données A peine avons-nous commencé à explorer les nouveaux modèles d’affaires du Web 2.0 que déjà se profile un nouveau paradigme prometteur : le web de données. Les applications du Web 2.0 reposent de plus en plus sur la gestion, l’analyse et l’exploitation des massives quantités de données issues des UGC. 2. information overload ("seven months" by dylanroscover) 3. 4. 5. 6.

Metalogue: Search Results I'm at the VALA2010 conference in Melbourne, a library technology conference comparable in some ways to the LITA national conferences in the U.S. VALA opened yesterday and will continue through Thursday (Melbourne's Thursday that is). Lots of interesting stuff being discussed here. I was the first of several keynote speakers. Late yesterday a VALA conference participant, speaking at the end of the keynote on OpenCalais by Tom Tague of Thomson Reuters, suggested that WorldCat be uploaded in OpenCalais. It's an interesting notion to consider in the context of the OCLC cooperative. My colleagues Roy Tennant and Don Hamparian already started a conversation with Tom, and I hope to join in that conversation later in the conference. OCLC has done a great deal of work on identifying individuals that can be seen at and mentioned both in my plenary session.

Traditionally wax had been used to make models but wax models were delicate and susceptible to changes in temperature which could cause them to melt or lose their shape. A pioneer of this form of modelling was Louis Thomas Jérome Auzoux (1797-1880) a French medical graduate. A common feature of many of Auzoux's models is the use of paint on a thin plaster layer which covered the papier-mâché. In 1865 Auzoux, introduced a new line of large scale botanical models for educational use. Although Auzoux used moulds to make multiple copies of his models they were still extremely labour intensive and as a result were never produced in large numbers. Geoff Barker, March, 2007

Free Computer, Programming, Mathematics, Technical Books, Lecture Notes and Tutorials Synaptic Web Stay updated about the Synaptic Web on Twitter via @SynapticWeb The Synaptic Web By Khris Loux, Eric Blantz, Chris Saad and you... The Internet is constantly evolving. As the speed, flexibility and complexity of connections increase exponentially, the Web is increasingly beginning to resemble a biological analog; the human brain. But what exactly is it that’s makes us, or the Web, smart? In the brain, neurologists now believe that it is the density and flexibility of the connections between neurons, not simply neurons themselves, which are at the root of intelligence. Even if the total number of brain cells, or neurons, begins to diminish in early adulthood, our ability to generate new connections between neurons and between different parts of the brain – what neurologist call “plasticity” - persists throughout life. Signs of the emerging Synaptic Web abound. The same is true for Social Networks. Social profiles are becoming real-time streams. Databases are becoming data peers.

Calais 4.0 Released: Linked Data Meets the Commercial Web Thomson Reuters is today launching the latest version of its Calais web service and open API, Calais 4.0. Calais is a toolkit of products that enables publishers to incorporate semantic functionality within their properties - enabling them to categorize content as people, places, companies, facts, events, and more. Calais 4.0 is perhaps the most significant version since the launch of Calais one year ago, because it enables publishers to connect to the Linked Data web standard that Sir Tim-Berners Lee and others in the Semantic Web community have been promoting over the past few years. Up till now, we have yet to see much commercial activity in Linked Data - developments have been largely confined to the academic and scientific communities. So we think Calais 4.0 represents an important move forward in the commercial Semantic Web - and we expect to see some big media companies using it before long. What's New in 4.0 1. Calais 4.0, explained Tague, fills in the final 2 of those pillers.

Downstream Web 3.0 A short story about the Semantic Web. Some Internet experts believe the next generation of the Web - Web 3.0 - will make tasks like your search for movies and food faster and easier. Instead of multiple searches, you might type a complex sentence or two in your Web 3.0 browser, and the Web will do the rest. For example, you could type "I want to see a funny movie and then eat at a good Mexican restaurant. What are my options?" That's not all. Eventually you might be able to ask your browser open questions like "where should I go for lunch?" Watch the full documentary now

Root System Drawings - Wageningen University & Research - Image Collections About this collection This collection holds 1,180 drawings, the outcome of 40 years of root system excavations in Europe, mainly in Austria. The drawings, their analysis and description were done by Univ. Copyrights and credits If you want to use and/or distribute the scans of the original drawings of the Root Systems, please contact the copyright holders of this collection. History Root systems research The knowledge of root depth and spatial extension of different plant species in arable land and grassland immensely helped to better understand their growth conditions, and, in turn, this helped to develop several new farming ideas. Their work led to a number of publications, and is a counterpart to the work by John E. Wurzelatlas covers Erwin Lichtenegger continued to draw the whole plant of their findings, including the root and shoot. One day the researchers were preparing a root sample on a dike in the Netherlands. More information Atlases: In the news:
