L'ePSI Platform a mis au point l'ePSI Scoreboard, un outil de benchmark des pays européens sur l'ouverture de leurs données publiques. Encore à l'état de Bêta, l'ePSI Scoreboard est complet depuis le 13 mars dernier, avec l'ajout des données de l'Autriche, de la République Tchèque et du Royaume-Uni. Le principe est simple : noté sur un score global de 700, chaque Etat se voit attribuer un certain nombre de points selon qu'ils remplissent tel ou tel critère favorisant l'open data. Sept catégories sont distinguées : l'application de la directive PSI de 2003, la pratique de la réutilisation, les formats, la tarification, la présence ou non d'accords d'exclusivité, les données publiques locales et enfin les évènements et activités dédiés à l'open data.

Concept map This article or section is a stub. A stub is an entry that did not yet receive substantial attention from editors, and as such does not yet contain enough information to be considered a real article. In other words, it is a short or insufficient piece of information and requires additions. 1 Definition A concept map is a kind of visualization and a kind of diagram, i.e. a graphical representation of some domain knowledge. A concept map is a graphical representation of a person's (student's) knowledge of a domain. 2 Typology of concept maps Concept maps can be defined in a more narrow sense as by Novak & Cañas (2006) - see below - or more generally as a drawing that somehow connects concepts. According to structural properties Spider-like maps with labeled arcs (the typical concept map) Hierarchical maps (like mind maps) Various diagrams, e.g. flow charts Formal maps like UML diagrams, Formal semantic networks, Topic maps, etc. According to purpose The typical concept map I.e.

An Overview of the Euro Crisis - Interactive Graphic Arrows show imbalances of debt exposure between borrowers in one country and banks in another; arrows point from debtors to their bank creditors. Arrow widths are proportional to the balance of money owed. For example, French borrowers owe Italian banks $50.6 billion; Italian borrowers owe French banks $416.4 billion. The difference — their imbalance — shows France's banking system more exposed to Italian debtors by about $365.8 billion. The risk to countries’ debts and economies is indicated by color: More worrisome Greece amassed a huge debt that it has scant hope of repaying. If there is no firewall or if it is inadequate, it would be easy to imagine a run on banks. If no preventative measures are taken, a chain of events like this could unfold: In reaction to a Greek collapse, investors become worried about their exposure to other risks in the region. Italy may not be able to protect its banks if there is a loss of confidence.
Wikidata Wikidata (www.wikidata.org) aims to create a free knowledge base about the world that can be read and edited by humans and machines alike. It will provide data in all the languages of the Wikimedia projects and allow for the central access to data in a similar vein as Wikimedia Commons does for multimedia files. Wikidata is a new Wikimedia hosted and maintained project. The initial development of the project is funded with a generous donation by the Allen Institute for Artificial Intelligence [ai]2, the Gordon and Betty Moore Foundation, and Google, Inc. Further information Impact on Wikipedia We are working on three major things: Centralizing language linksProviding a central place for infobox data for all WikipediasCreating and updating list articles based on data in Wikidata Status We are posting regular summaries of the activities around Wikidata on Status updates.
An Annotated Bibliography of Concept Mapping A rich narrative-style bibliography of concept mapping (reviewing six articles published between 1992-2005). Articles reviewed include: (1) Cognitive mapping: A qualitative research method for social work (C. Bitoni); (2) Collaborative concept mapping: Provoking and supporting meaningful discourse (C. Boxtel, J. Linden, E. Roelofs, and G. Descriptors: Concept Mapping, Qualitative Research, Maps, Cognitive Mapping, Social Work, Annotated Bibliographies, Cognitive Processes, Cooperative Learning, Evaluation Methods, Psychology, Causal Models, Research Methodology, Knowledge Level, Validity Explorable Explanations Bret Victor / March 10, 2011 What does it mean to be an active reader? An active reader asks questions, considers alternatives, questions assumptions, and even questions the trustworthiness of the author. An active reader tries to generalize specific examples, and devise specific examples for generalities. An active reader doesn't passively sponge up information, but uses the author's argument as a springboard for critical thought and deep understanding. Do our reading environments encourage active reading? Explorable Explanations is my umbrella project for ideas that enable and encourage truly active reading. This essay presents examples of few initial ideas: A reactive document allows the reader to play with the author's assumptions and analyses, and see the consquences. An explorable example makes the abstract concrete, and allows the reader to develop an intuition for how a system works. 1. Ten Brighter Ideas was my early prototype of a reactive document. drag The way it is now: Analysis:
Introducing the DataStore A major new feature in the DataHub is good news for data wranglers. The DataStore allows users to store and load structured data into a database, where it can be queried, filtered, or accessed from other programs via a rich data API. The API is also used by CKAN’s inbuilt Recline Data Explorer, giving in-page previews of the data with full text search, filtering, sorting and graphing, as in the screenshots below: These new DataHub capabilities are powered by the recently enhanced DataStore and Data API functionality of our open-source CKAN data management system, which as well as powering the DataHub runs many other data portals including data.gov.uk.
