"Posted by Dario Taraborelli on August 2, 2012 Improving the quality of articles has long been one of the primary aims of contributors to Wikipedia, and is one of the Wikimedia movement's 2010-15 strategic priorities, but measuring it objectively has remained a challenge. In 2005, Nature famously reported that Wikipedia articles on scientific topics contained just four errors per article on average, compared to three errors per article in the online edition of Encyclopaedia Britannica. Britannica objected to the report, but Nature stood by it, and the report remains widely cited today. Since that time, however, there have been relatively few independent analyses of Wikipedia article quality, despite the enormous growth of the project. Wikipedia today counts more than 23 million articles across languages (more than 4 million articles in the English Wikipedia alone) compared to 3.7 million total articles in 2005; today it ranks 6th by overall traffic according to Alexa, while it ranked 37th in 2005. (...) The Wikimedia Foundation is announcing the release of a pilot study conducted by Epic, an e-learning consultancy, in partnership with Oxford University - "Assessing the Accuracy and Quality of Wikipedia Entries Compared to Popular Online Alternative Encyclopaedias: A Preliminary Comparative Study Across Disciplines in English, Spanish and Arabic." The study compared a sample of English Wikipedia articles to equivalent articles in Encyclopaedia Britannica, Spanish Wikipedia to Enciclonet, and Arabic Wikipedia to Mawsoah and Arab Encyclopaedia. 22 articles in the sample were blind-assessed by 2 to 3 native speaking academic experts each, both quantitatively and qualitatively. The small size of the sample does not allow us to generalize the results to Wikipedia as a whole. However, as a pilot primarily focused on methodology, the study offers new insights into the design of a protocol for expert assessment of encyclopedic contents. For our editor community a

Google Faces searching for faces on Google Maps,  The way we perceive our environment is a complex procedure. By the help of our vision we are able to recognize friends within a huge crowd, approximate the speed of an oncoming car or simply admire a painting. One of human's most characteristic features is our desire to detect patterns. We use this ability to penetrate into the detailed secrets of nature. However we also tend to use this ability to enrich our imagination. Hence we recognize meaningful shapes in clouds or detect a great bear upon astrological observations. Objective investigations and subjective imagination collide to one inseparable process. The tendency to detect meaning in vague visual stimuli is a psychological phenomenon called Pareidolia, and captures the core interest of this project.  video tutorial: http://vimeo.com/66055499#

"Shortly after its foundation in the 9th century, the Benedictine abbey of Vézelay acquired the relics of St Mary Magdalene and since then it has been an important place of pilgrimage. St Bernard preached the Second Crusade there in 1146 and Richard the Lion-Hearted and Philip II Augustus met there to leave for the Third Crusade in 1190. With its sculpted capitals and portal, the Madeleine of Vézelay - a 12th-century monastic church - is a masterpiece of Burgundian Romanesque art and architecture.\nhttp://whc.unesco.org/en/list/84/"

Veramente, aggiungo questo link per vedere se l'Unesco ha anche disabilitato l'embed per i suoi video su opere/luoghi del suo Patrimonio Mondiale dell'umanità. Ecco l'embed: Aggiornamento post posting: Eh già: è bloccato anche per questo video. Chissà quanti siti / blog educativi che avevano inserito questi video sul patrimonio mondiale dell'Unesco si ritrovano con player neri e la richiesta di andare a vedere il video su YouTube...

M'ero dimenticata questo post. Per fortuna me l'ha ricordato uno spammer che ha cercato di farvi un trackback, il ché ha suscitato una notifica via email. Cosa interessante: il video originale dell'UNESCO esiste ancora, e può essere embeddato, salvo sul mio blog Webmultimediale.org In effetti, se si cerca di farlo partire, appare soltanto: "This video contains content from Unesco, who has blocked it from display on this website. Watch on YouTube". Mo' proverò a rifare il post sul blog Wordpress.

Correzione: non funziona l'embed nemmeno sul blog WordPress . Ero stata tratta in inganno dal fatto che il codice embed del video continua ad essere offerto per il video originale in http://www.youtube.com/watch?v=QC4lkyBc-1k : E anche qui dà lo stesso risultato bloccato:

0 July 2013 Last updated at 08:52 GMT Help 3D printing has been around for some time but now the technology is available for the same price as a top-end TV at shops. 3D printing has been hailed as the future of manufacturing. The technology works by building up layer upon layer of material - typically plastic - to build complex solid objects. The idea is that as the printers become cheaper, instead of buying goods from shops, consumers will instead be able to download designs and print out the items at home. Technology Correspondent Rory Cellan-Jones has been finding out what 3D print stores offer

"WHAT IS CIRCOS? CIRCULAR VISUALIZATION Circos is a software package for visualizing data and information. It visualizes data in a circular layout - this makes Circos ideal for exploring relationships between objects or positions. There are other reasons why a circular layout is advantageous, not the least being the fact that it is attractive. Circos is ideal for creating publication-quality infographics and illustrations with a high data-to-ink ratio, richly layered data and pleasant symmetries. You have fine control each element in the figure to tailor its focus points and detail to your audience."

"August 5, 2012 by Tony Bates TED Talks: Daphne Koller: What we're learning from online education Daphne Koller, one of the two founders of Coursera, describes some of the key features of the Coursera MOOCs, and the lessons she has learned to date about teaching and learning from these courses. The video is well worth watching, just for this. However I'm probably going to suffer the same kind of fate of the Russian female punk band, Pussy Riot, by spitting on the altar of MOOCs, but this TED talk captures for me all that is both right and wrong about the MOOCs being promoted by the elite US universities. Let me start by saying that I actually applaud Daphne Koller and her colleagues for developing massive open online MOOCs. Any attempt to make the knowledge of some of the world's leading experts available to anyone free of charge is an excellent endeavour. If only it stopped there. What I object to is the hubris and misleading claims that are evident in this TED video. As someone once said about one of Sigmund Freud's lectures, what is new is not true, and what is true is not new."

Importante analisi fatta da uno specialista dell'insegnamento a distanza, tutto all'inizio di Coursera

"Overview - This course is offered by University of Zurich with Prof Paul-Olivier Dehaye and his students. This lesson plan is created by Dilrukshi Gamage (www.sdgamage.weebly.com) a MOOC student from this class due to few reasons. 1. Course started with giving some ideas, but now it appears no more ideas facilitated 2. Forums are closed and we have no clue of what to do 3. Students who take this course or any of coursera for the first time will be wondering and might lose the context of learning. 4. This lesson plan will guide us to collaboratively find solution to be in synchronized and learn from the time we invest in this. Introduction - The course named Teaching goes massive : new skills needed. It is our responsibility to find out what are the skills we need when we are teaching to a massive class.. or any class. Prof.Paul mentioned some experiments which we can do and previous forums already started and gone very well until suddenly closed everything. So let us drive this MOOC , learn to learn ourselves how to be organized and learn from each other. Anyone can suggest things but not like as forums it has to be much more effective. This document will contain how to participate and what can you do in contributing to expand your learning. Don't worry this will not stop suddenly as we the students are in charge. First step lets set some objectives so we can see did we achieve when we finish this course. Objectives - After you complete this course 1. You will learn how to learn yourselves to work without a real teacher or a lecturer. 2. You will learn to make communications and build a network where you can share and learn throughout your interest. 3. You will learn to work on inclusive projects in the same course ( by inclusive what I mean was anyone can work in one project or more) 4. You will gain knowledge on what skills you need and how to handle it when teaching is massive Where to contact - Please use the links provided in collaborating

Chris Hoofnagle, director of BCLT's privacy programs | 3/6/13 "...We need to be less infatuated with "the cloud," which to some extent is a marketing fad. Many of the putative benefits of the cloud are disclaimed in these services' terms of service. For instance, a 2009 survey of 31 contracts found that, "…In effect, a number of providers of consumer-oriented Cloud services appear to disclaim the specific fitness of their services for the purpose(s) for which many customers will have specifically signed up to use them." The same researchers found that providers' business models were related to the generosity of terms. This militates towards providers that charge some fee for service as opposed to "free" ones that monetize user data. We should charge our IT professionals with the duty of documenting problems with outsourced services. To more objectively understand the cloud phenomenon, we should track the real costs associated with outsourcing, including outages, the costs of managing the relationship with Google, and the technical problems that users experience. Outsourcing is not costless. We could learn that employees have simply been transferred from the operation of CalMail to the management of bMail. We should not assume that systems mean fewer people-they may appropriately require meaningful staffing to fulfill our needs. As the expiration date of system wide Google contract approaches in June 2015, these metrics will help us make an economical decision. Finally, there are technical approaches that, if effective, could blunt, but not completely eliminate, the privacy problems created by cloud services. Encryption tools, such as CipherCloud, exist to mask data from Google itself. This can help hide the content of messages, reduce data mining risks from Google, and cause the government to have to come to Berkeley officials to gain access to content. The emergence of these services indicates that there is a shared concern about s
