IntroOpenEd 2007: an experience on Open Education by a virtual community of teachers | ... - 0 views

  •  
    "Antonio Fini, Andreas Formiconi, Alessandro Giorni, Nuccia Silvana Pirruccello, Elisa Spadavecchia, Emanuela Zibordi Abstract In Fall 2007 David Wiley, professor at Utah State University held a course about Open Education. That time, however, Dr Wiley's course was followed by a rather unusual group of students. The Fall 2007 edition, in fact, was available to anybody, free of charge, all over the world. The only requisite required was the possession of a blog for the completion of the weekly assignments. The present paper, whose authors attended the course completing it successfully, is an account of the experience they had. It can be considered an innovating experience from many different viewpoints and can be regarded as an example of how the world of the formal education can meet the demands of the informal one, in the broader landscape of professional training and lifelong learning.

    "Welcome to the Weeks Pages for CyberOne: Law in the Court of Public Opinion. These pages will primarily be maintained by the Harvard Law School students enrolled in the course, but, as is customary with a Wiki, are available for anyone to edit. There will be (at least) one page for each week of the course. On these pages you can expect to find a presentation of all of the material from the particular week of the course including the video of the lecture (once it is available), notes from the class meeting, summaries and discussions of the readings, and more. We invite everyone to engage in open discussion of the week's materials on the discussion page for a given week. "

    • Claude Almansi
       
      "E tutti e tre [mp3, jpeg, mo4) usano i sistemi di compressione più efficaci, ovvero quelli non conservativi," - e ogg (audio) e ogv (video) sono anche non conservativi? - conservativo = lossless in inglese?
  • ...6 more annotations...
  • Sempre con l’editore di testo scrivo “pippo pippo…” tante volte (alla Shining – non mi sta vedendo nessuno…)
    • Claude Almansi
       
      Sarà il caso di avvertire i famigliari e le forze dell'ordine? :D
  • Il formato GIF usa una compressione conservativa. Questo lo rende adatto a immagini che contengono testo o grafica composta da linee. Si può usare per fare immagini animate.
    • Claude Almansi
       
      Su G+ un contatto ha scritto di Gfycat, un'app web + server che consente di trasformare i .gif in video html5, secondo http://gfycat.com/about . Ma come funziona? È una vettorializzazione del gif?
  • esportare un documento qualsiasi – testo, foglio di lavoro o altro – in PDF vuole dire farne una sorta di fotografia, ovvero congelarlo in un’immagine, e per di più un’immagine vettoriale, perché così risulta meno sensibile alla modalità con la quale viene rappresentato, grazie al meccanismo ad oggetti che abbiamo visto.
    • Claude Almansi
       
      Era certamente vero nel 2003, quando J. Nielsen scrisse http://www.nngroup.com/articles/pdf-unfit-for-human-consumption/ . Ma lo è ancora? Nei PDF odierni, a patto che non siano fatti con uno scanner senza OCR, si può selezionare e copiare un brano e si possono leggere con una sintesi vocale o una barra braille. Non significa forse che quei nuovi PDF sono testuali?
  • Anche Inkscape ha un formato di riferimento che conserva tutto ciò che serve per conservare il lavoro fra sessioni successive, è lo SVG. Valgono le stesse considerazioni fatte a proposito del formato XCF di Gimp.
    • Claude Almansi
       
      Lo stesso vale anche per .aup, per il trattamento dell'audio in Audacity? O i progetti Audacity funzionano con un sistema di livelli (layer)?
  • Infine il terzo fatto che fa la differenza in materia di elaborazione di immagini: l’esistenza dei livelli (layers).
    • Claude Almansi
       
      Cfr annotazione precedente sui formati che salvano tutte le fasi di lavoro e Audacity.
    • Claude Almansi
       
      E queste annotazioni che sto aggiungendo sul tuo testo con Diigo, che in teoria tutti dovrebbero poter leggere se visualizzaono la pagina tramite l'URL https://diigo.com/01lqff , e che producono delle annotazioni nel segnalibro condiviso col gruppo Diigo ltis13 - anche queste annotazioni sono un livello/layer?
    • Claude Almansi
       
      Poi nei video mostrati sul sito ted.com, il player in realtà può mostrare 2 cose: il video e un file testuale a scelta di sottotitoli. E quei file testuali di sottotitoli producono le trascrizioni interattive in varie lingue che si possono attivare sotto il player. Anche lì si tratta di livelli/layer? Poi quel player di TED.com ha anche una funzione che ti consente invece di scaricare il video con i sottotitoli che vuoi incisi dentro il video, cioè in un unico video. È la stessa cosa che quando lavori con i livelli per produrre un'immagine, o con le piste per produrre un audio, poi esporti il tutto o in jpg o in mp3, ad es.?
  • Se la suggestione per qualcuno c’è stata allora costui proverà a fare qualcosa. Se avrà problemi lo scriverà, e noi lo aiuteremo.
    • Claude Almansi
       
      Grazie! Poi ci provo ... e aggiungerò semmai altre domande con le annotazioni Diigo che finiranno in https://diigo.com/01lqff , di cui non ho ancora capito se è un layer/livello o meno ;-)

Google's 'Babel fish' heralds future of translation | TechCentral, Ashish Venugopal / D... - 0 views

  •  
    "In Douglas Adams's famous Hitchhiker's Guide to the Galaxy series of science-fiction books, interstellar species use Babel fish - "small, yellow, leech-like" creatures that feed on "brain-wave energy" - to translate speech in real time. A team of developers at Google is working on the real thing, using statistical models to translate different languages, including Afrikaans, on the Web and on mobile phones, using voice input and output as well as text. TechCentral sat down with Google Translate research scientist Ashish Venugopal at Google's headquarters in Silicon Valley last week and asked him about the stumbling blocks to effective real-time translation and the future of the technology. This is an edited transcript of that interview. (...).Do you have a team of linguists working all over the world? We have a team of statisticians, all working right over there [points and laughs]. It's less linguistically orientated. There are linguistic ideas that influence our decisions. To give you an example, when I was working on the last set of Indian languages that were launched, I didn't use any linguistic knowledge; I used Wikipedia and my grandmother. So, it's Wikipedia, my grandmother and statistics. That's what we use to put a language together. - Duncan McLeod, TechCentral"

Seven years after Nature, pilot study compares Wikipedia favorably to other encyclopedi... - 2 views

  •  
    "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

Odds And Not Ends: Automated translation: Babelfish 101 - DDN C. Almansi 2005-03-04 - 0 views

  •  
    "Babelfish 101 (also appliable to the Google translator) Babelfish is not a little polyglot genius lurking in your computer or in cyberspace Babelfish is A computer program made of lists of words and phrases in different languages complex, but not all-covering, rules applied to these lists in order to produce translations Babelfish will not give you a publishable or even editable version of your text in another language analyse and render correctly complex sentence structures always choose the meaning you had it mind if two or more words have the same spelling confuse two words due to approximate memory Babelfish will produce apparent gibberish give you a rough idea of what someone else's original text is about Therefore, when dealing with Babelfish, you must use commonsense Don't use Babelfish to produce a translation into another language, especially if you don't know that language If you know others will use Babelfish to read you, use simple sentence structure and avoid terms that can have several meanings If you read something absurd or outrageous in a Babelfish translation, don't immediately attribute the absurdity or outrage to the author. Try to guess from the context what the author might have meant Compare what the author might have meant with what you know of Babelfish's limitations, to see if these limitations are the likely cause of the apparent absurdity or outrage be wary of commonsense The author may indeed have expressed something that would baffle you even if you both used the same language: because your cultural references are different, because s/he is using irony because (make your own list) ask when in doubt ;-)" Avevo scritto questo post su un blog del Digital Divide Network (DDN) che non c'è più.

7 Ways to Caption Your Videos - YouTube 2014-11-28 - 0 views

  •  
    "Published on Nov 28, 2014 For someone who has no idea how to caption a video this might be a bit confusing. I'm not sure. (Ask otherwise). But I thought I'll upload it anyway. (What I could have explained in the video is that numer 5-7 are how to make captions that are IN youtube, which aren't permanently on the screen. And you press a button in the bottom right corner of the video to turn them on. But I kind of assumed that everyone knew that when making the video. However having shown this to my confused little brother I realize that's not always the case). (OR just watch Paul Talks video. https://www.youtube.com/watch?v=_H57r... ) 1. Handheld written captions. 2. Scanned written text. 3. Text added when editing. 4. "Upload a file" 5. Write a script. 6. Write new captions as you're watching the video. 7. Automatic Captions.
