TopicMaps.org - Topic Maps La troisième frontière du Web Chacun sent que le Web entre aujourd’hui dans une nouvelle phase de son développement. Les tentatives de synthèse fleurissent, mais ne semblent pas suffire à rendre compte des évolutions en cours. Peut-être sont-elles encore trop vagues? ou déjà trop précises? Peut-être trouvera-t-on d’ailleurs inutile de vouloir décrire les évolutions d’ensemble du Web? Je crois pourtant que la nature décentralisée du Web offre un moyen de comprendre son orientation. C’est cette piste que je voudrais explorer ici. Les principes fondateurs du Web Ces principes sont simplement les objectifs initiaux que Tim Berners-Lee et Robert Caillau ont donnés à leur projet. 1- Permettre à chacun d’accéder à tout type de document 2- Permettre à chacun de diffuser ses propres documents 3- Permettre à chacun d’organiser l’ensemble des documents Le Web initial, micro-démocratie où chacun disposait de tous les attributs d’un média, assura son propre développement et fixa durablement ses orientations.

Protege Wiki Ding.fm >Under Construction< Web Ontology Language Un article de Wikipédia, l'encyclopédie libre. Pour les articles homonymes, voir OWL. Le langage OWL est basé sur les recherches effectuées dans le domaine de la logique de description. Il peut être vu en quelque sorte comme un standard informatique qui met en oeuvre certaines logiques de description, et permet à des outils qui comprennent OWL de travailler avec ces données, de vérifier que les données sont cohérentes, de déduire des connaissances nouvelles ou d'extraires certaines informations de cette base de données. Il permet notamment de décrire des ontologies, c'est-à-dire qu'il permet de définir des terminologies pour décrire des domaines concrets. Une terminologie se constitue de concepts et de propriétés (aussi appelés « rôles » en logiques de description). Une extension de RDF[modifier | modifier le code] RDF permet par exemple de décrire que <Jean> est le père de <Paul>, au travers des individus <Jean>, <Paul>, et de la relation est le père de. .
Revolución tecnológica para aprender inglés en el aula tic | ¿Para que tus alumnos aprendan inglés es necesario que conozcan las reglas que gobiernan la gramática inglesa? ¿Es imprescindible que entiendan que significa la terminología “pretérito perfecto” o “preposiciones”? De hecho si preguntas, la mayoría de nativos de habla inglesa no recuerdan el significado de estas palabras, pero en cambio sí utilizan las construcciones gramaticales correctas cada día. Con esta filosofía, dos herramientas online gratuitas, Voxy para escuelas y English Attack, proponen una forma alternativa para que tus alumnos de entre 15 y 35 años, entiendan y hablen inglés rápidamente y con mayor facilidad. Juegos, redes sociales, trailers de películas, animaciones y música pop son los protagonistas de este sistema multimedia e interactivo, permitiendo que una generación acostumbrada a la información audiovisual aprenda y mejore el inglés. La lógica y éxito de estas dos propuestas innovadoras se basan en: Voxy para escuelas y docentes English Attack Foto por Daremoshiranai
Semantic Technology’s Role in Big Data Solutions? Forbes has published an article that points out an opportunity for Semantic Technology companies. The article discusses the lack of understanding in companies around big data. Author Gil Press writes, “Listening to Gartner analysts Sheila Childs and Merv Adrian talking yesterday about big data infrastructure challenges, I was reminded of a story Mike Ruettgers, former EMC CEO, liked to tell about similar challenges in the early 1990s. At the time, the reigning buzzword was ‘client/server computing,’ signaling a shift to relatively inexpensive servers based on the UNIX operating system. The early adopters were not the people in the glass houses, the data center managers. He goes on, “Visiting the CIO of John Deere, Ruettgers asked him whether he saw these ‘distributed systems’ coming back to be managed by the IT department. Press notes, “You may find that all of your best DW, BI, MDM practices for SDLC, PMO and Governance aren’t directly applicable to or just don’t work for Big Data.
Ontology creation for the rest of us… COE is a project whose goal is to develop an integrated suite of software tools for constructing, sharing and viewing OWL encoded ontologies based on CmapTools, a concept mapping software used in educational settings, training, and knowledge capturing. Concept maps provide a human-centered interface to display the structure, content, and scope of an ontology. Currently, our work focuses on developing conventions for constructing new Cmap OWL ontologies that will assist and guide users when forming class and property relationships among the concepts in the ontology. In addition, we are working on clustering and searching techniques that support the reuse of existing ontologies. An overview presentation is here. Startup instructions are here. The manual is here.

IsaViz Overview News IsaViz and Java 1.6 (2007-10-21) IsaViz 2.x is not compatible with Java 1.6 or later. IsaViz and GraphViz (2007-05-23) IsaViz 2.x is not compatible with GraphViz 2.10 or later. Several bugs have been fixed in the FSL engines for Jena, Sesame and the visual FSL debugger embedded in IsaViz. Fresnel in IsaViz (2006-05-19) IsaViz 3.0 now supports Fresnel lenses and several elements of the Core Format Vocabulary. FSL for Sesame 2-alpha-3 (2006-04-25) The FSL engine for Sesame 2 now works with version 2alpha3 instead of version 2alpha1. FSL for Sesame 1.2.2 (2005-12-06) In addition to the Sesame 2.0 implementation of FSL, there is now a Sesame 1.2.2 implementation written by Ryan Lee from project Simile. Java FSL Documentation available (2005-11-18) Documentation for the three existing Java FSL engine implementations (for Jena, Sesame and IsaViz) is now available. FSL for Sesame 2.0 (2005-11-15) Fresnel comes with a companion proposal specifying a path language for RDF called FSL. Screenshots
RelFinder - Visual Data Web Are you interested in how things are related with each other? The RelFinder helps to get an overview: It extracts and visualizes relationships between given objects in RDF data and makes these relationships interactively explorable. Highlighting and filtering features support visual analysis both on a global and detailed level. The RelFinder is based on the open source framework Adobe Flex, easy-to-use and works with any RDF dataset that provides standardized SPARQL access. Check out the following links for some examples: The RelFinder can easily be configured to work with different RDF datasets. The RelFinder can also be more deeply integrated with your project: Integrating the RelFinder See the following examples of how the RelFinder is integrated into other projects: Ontotext applies the RelFinder to enable an exploration of relationships in the biomedical domain. All tools on this website are research prototypes that might contain errors.
Tracker Tracker is a search engine, search tool and metadata storage system. It allows you to find the proverbial needle in your computer's haystack as well as providing a one stop solution to the organisation, storage and categorisation of your data.

It also encompasses some ideas about being able to automatically share information between different people. This concept is very much related to the Semantic Web but is distinct insofar as its main concern is the personal use of information. General description[edit] The vision of the semantic desktop can be considered as a response to the perceived problems of existing user interfaces. Secondly there is the problem of relating different files with each other. Related to this a user will often access a lot of data from the Internet which is segregated from the data stored locally on the computer, being accessed through a browser or other programs. Standardization effort[edit]
