List of academic databases and search engines From Wikipedia, the free encyclopedia This article contains a representative list of notable databases and search engines useful in an academic setting for finding and accessing articles in academic journals, institutional repositories, archives, or other collections of scientific and other articles. Databases and search engines differ substantially in terms of coverage and retrieval qualities.[1] Users need to account for qualities and limitations of databases and search engines, especially those searching systematically for records such as in systematic reviews or meta-analyses.[2] As the distinction between a database and a search engine is unclear for these complex document retrieval systems, see: the general list of search engines for all-purpose search engines that can be used for academic purposesthe article about bibliographic databases for information about databases giving bibliographic information about finding books and journal articles.

Open data An introductory overview of Linked Open Data in the context of cultural institutions. Clear labeling of the licensing terms is a key component of Open data, and icons like the one pictured here are being used for that purpose. Overview[edit] The concept of open data is not new; but a formalized definition is relatively new—the primary such formalization being that in the Open Definition which can be summarized in the statement that "A piece of data is open if anyone is free to use, reuse, and redistribute it — subject only, at most, to the requirement to attribute and/or share-alike. Open data is often focused on non-textual material[citation needed] such as maps, genomes, connectomes, chemical compounds, mathematical and scientific formulae, medical data and practice, bioscience and biodiversity. A typical depiction of the need for open data: Creators of data often do not consider the need to state the conditions of ownership, licensing and re-use. I want my data back. Closed data[edit]
Data and maps The pan-European High-Resolution Vegetation Phenology and Productivity product suite (HR-VPP) are provided at a high spatial resolution (10 m x 10 m) with a high repeat frequency. They are derived from the optical Sentinel-2 constellation data (Sentinel-2A and Sentinel-2B) with a revisit time of 5 days. They are generated over the entire EEA39 region (33 member countries and 6 cooperating countries) from January 1 2017 onwards, with a daily, 10-daily and yearly frequency (see below). The HR-VPP product suite contains 3 product groups, 31 product types, 1522 files and more than 900.000 tiles per year, which totals more than 80 Terra Bytes of data, per year. The figure shows the difference in emissions of POPs between 2005 and 2019 This interactive data viewer provides accounts of imperviousness, i.e. land surface sealing status in Europe (EEA39 and EU27+UK) for the year 2018. Historical greenhouse gas emissions from the EU buildings sector show a decreasing trend since 2005.

Début juillet paraissait dans la revue MyScienceWork un article, repris ensuite par La gazette des Communes, puis par Rue89 / Nouvel Observateur, intitulé “L’Open data est-il un leurre politique ?”. Cette interview d’Evelyne Ruppert, une sociologue britannique, notamment à l’origine du blog “Big data et society”, s'inspire de ses travaux sur la transparence britannique, qu’elle semble bien connaître, mais porte sur la démarche française, qu’elle semble moins connaître. Evelyne Ruppert y développe une analyse que l’on pourrait résumer comme suit : - la transparence absolue est un leurre, car les gouvernements choisissent toujours ce qu’ils communiquent, et ne partagent jamais les informations les plus importantes ; - la transparence, parce qu’elle ne peut jamais être complète, ne crée pas la confiance mais au contraire la défiance ; De nombreux amis me demandent ce que je pense ce ce papier. Je ne sais si ce raisonnement existe quelque part. Transparence, accountability, participation...

Ebook : le cahier de l’OpenData 2010 Acteur du datajournalism, Owni suit de près le mouvement open data. Les fortunes sont diverses selon les pays. Retour sur les avancées et les reculs de l'année 2010 en dix articles. «Nous ouvrons les gouvernements» : si le slogan de WikiLeaks semble voir été entendu, au moins en partie par les gouvernements anglo-saxons, comme en témoignent les initiatives des Etats-Unis, de la Grande-Bretagne, de l’Australie et du Canada, la majeure partie des pays restent à la marge. Ainsi, les pays européens peinent à suivre le mouvement de l’open data, malgré la mise en place de la directive européenne INSPIRE en 2007, et la France ne déroge pas à cette règle. Les initiatives les plus poussées se développent au niveau local, Bretagne en tête, et le mouvement de l’open data est d’abord porté par les citoyens, les journalistes, les universitaires et les communautés open source.

Wikimapia Wikimapia fue creada por Alexandre Koriakine y Evgeniy Saveliev. Este proyecto fue lanzado al público el 24 de mayo del 2006, con el objetivo de que "describamos todo el planeta Tierra". Wikimapia no está directamente relacionada con Wikipedia o la Fundación Wikimedia. No obstante, en su sitio web dice que "fue inspirada por Wikipedia"[cita requerida]. A diferencia de otros wiki-sistemas, Wikimapia no tiene una jerarquía administrativa. Todos los contribuyentes editan o corrigen de manera anónima y no hay un mecanismo supervisor o disciplinario aplicable a usuarios problemáticos. Wikimapia permite que sus contribuyentes añadan "puntos activos" (hotspots) a cualquier mapa, demarcados por rectángulos (dentro de una longitud máxima de 20 kilómetros, por cualquiera de sus lados) wiki-enlazados mediante una nota que suministre información sobre la localidad referida. Los enlaces se activan mediante clics dentro de cualquier rectángulo. Véase también[editar] OpenStreetMap
