Gastkommentar zu Big Data: Die Erkenntnis von nichts - NZZ.ch Manfred Schneider 2013-12-30 - 1 views

  •  
    "... Big Data sind vor allem Massen von Informationen, die wie ein digitales Biotop Heerscharen von Propheten hervorbringen, deren Augen bereits in das Morgenrot einer neuen Menschheitsepoche vordringen. Was allerdings auffällt, wenn man sich ein wenig durch den wachsenden Bücher- und Artikelberg zum Thema arbeitet, ist, dass sich die Beispiele für neuartige und spektakuläre Big-Data-Analysen wiederholen. Ganz vorneweg läuft ein Artikel in der Zeitschrift «Nature» aus dem Jahr 2009, der über die Zusammenarbeit von staatlichen Epidemiologen und Google-Mitarbeitern berichtete, die zwischen 2003 und 2008 ein Verfahren zur möglichen Prävention von Grippe-Epidemien entwickelt haben. Sie korrelierten einschlägige Suchmaschinen-Nachfragen nach Grippe-Symptomen, Medikamenten, Antibiotika in bestimmten Regionen mit der Frequenz von Arztbesuchen und stellten damit ein prognostisches Modell für den Verlauf einer Epidemie auf. Zuvor wurden aus mehreren hundert Milliarden Google-Anfragen rund 50 Millionen ausgefiltert, deren Stichworte dem Grippe-Thema zugewiesen werden konnten. Jetzt erlauben es avancierte Rechenverfahren, die Entwicklung einer Seuche beinahe in Echtzeit zu verfolgen und dabei Vorbeugemassnahmen zu treffen. Das Beispiel ist schlagend, vor allem darum, weil es sich unmittelbar ins Reich des Menschheitsheils fügt. Wer will künftig seine Google-Anfragen noch unter Datenschutz stellen, wenn es doch - das oberste Pathosregister ist hier am Platze - um das Leben von Tausenden geht? Die übrigen Beispiele, die die Big-Data-Literatur zur Verfügung stellt, fallen eher in das Feld des smarten Kommerzes. Dass Jeff Bezos, der Gründer von Amazon, seine Bücher nicht von Kritikern anpreisen lässt, sondern den Kunden immer wieder Bücher empfiehlt, die sie eigentlich bereits gelesen haben, ist eine solche smarte Big-Data-Idee. Wer ein Buch über Hühner bestellt, bekommt kurz darauf eines über Hähne empfohlen. Im Prinzip geht es darum, Real-Time-Informa

Are Infographics Making Us Stupid? - Make your ideas Art - 0 views

  •  
    "Published on March 18th, 2013 | by Guest Author [Kate Lee] Infographics are becoming an increasingly popular method of communicating information quickly and clearly. Great designs can reduce the complexity of information, making a process, product or service easily understandable and accessible to the general public. And a good infographic means that all of that information is presented in a way that is aesthetically pleasing to boot. But have infographics become too good at streamlining information? Have they become the fast food of graphic design - quickly digestible, but lacking in substance? Infographics: Guilty As Charged The web has lots of criticisms levelled at infographics and it's true that many are poorly created, failing to fulfil their purpose, using Papyrus or other crimes against design. The main complaints when it comes to infographics are: 1. Creates confusion: the data is presented in a manner that takes a long time to interpret, is difficult to follow and creates additional complexity instead of providing clarity. 2. Inaccurate information: [...] 3. Too long: [...] 4. General ugliness: [...] The problem with infographics is that so many people think it's easy to create them, when in fact it's a particular subset of skills in an already specialised profession.[...] Data Visualisation Requires Thinking That being said, there are truly great infographics out there that tick all the boxes: accurate information, presented in an effective visual manner that helps the audience interpret and understand quickly. And so we come to the point of this post: with complex information rendered so comprehensible, without the need to read long reports and with the ability to look at pictures and share it with all your friends - is there a danger that infographics cause the audience to stop thinking? In short, the answer is no. In most cases where the audience needs to think, the data isn't simple anyway. The mission of infographics is to re

    Titolo volutamente provocativo. Ottima presentazione delle "infographics", di cosa dovrebbero e potrebbero essere ma purtroppo spesso non sono, e degli risvolti cognitivi del loro uso.

Geospatial Metadata - Federal Geographic Data Committee - 1 views

  •  
    "Geospatial Metadata What are Metadata? A metadata record is a file of information, usually presented as an XML document, which captures the basic characteristics of a data or information resource. It represents the who, what, when, where, why and how of the resource. Geospatial metadata commonly document geographic digital data such as Geographic Information System (GIS) files, geospatial databases, and earth imagery but can also be used to document geospatial resources including data catalogs, mapping applications, data models and related websites. Metadata records include core library catalog elements such as Title, Abstract, and Publication Data; geographic elements such as Geographic Extent and Projection Information; and database elements such as Attribute Label Definitions and Attribute Domain Values."

Introduction to Circos, Features and Uses // CIRCOS Circular Genome Data Visualization - 1 views

  •  
    "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."

    "Copy your data From spreadsheets, to tables in web pages, databases-anywhere you can visualize a table with location data you can paste it into BatchGeo. If you are starting from scratch, we recommend using our Spreadsheet Template to get started with your data, then simply copy the data over to BatchGeo to create a pin map. Validate & set options We make our best guess at your intended columns like the address, city, state, zip code, or latitude / longitude. You may want to set the options yourself if you don't like the default behavior. Map locations We geocode your postcodes / addresses and make your map. It may take a few minutes depending on how many addresses you have, if you already had latitude and longitude in your data it will map instantly. After you are done mapping the addresses you can save to a web page using the "Continue & Save" option."

The good, not so good, and long view on Bmail « The Berkeley Blog - Chris Hoo... - 0 views

  •  
    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

SafeGov.org - Google admits data mining student emails in its free education apps 2014-... - 0 views

  •  
    "by Jeff Gould, SafeGov.org Friday, January 31, 2014 When it introduced a new privacy policy designed to improve its ability to target users with ads based on data mining of their online activities, Google said the policy didn't apply to students using Google Apps for Education. But recent court filings by Google's lawyers in a California class action lawsuit against Gmail data mining tell a different story: Google now admits that it does data mine student emails for ad-targeting purposes outside of school, even when ad serving in school is turned off, and its controversial consumer privacy policy does apply to Google Apps for Education."

    "Ho proposto di taggarsi. Specifico ancora: non se stessi, non qualsivoglia interesse, ma gli interessi sui quali si sente la necessità di un confronto,nell'ambito professionale, attinente all'insegnamento e dintorni. Non ho proposto di fare ordine. Sì, appiccicare etichette evoca l'idea di fare ordine, ma esistono anche altre prospettive. Qui l'etichettatura, il tagging, rappresenta un elemento di un metodo di ricerca; se vogliamo, una tecnica di data mining do-it-yourself. Data mining: insieme delle metodologie di analisi dei dati volte alla scoperta di caratteristiche emergenti in grandi masse di dati, già menzionata da Mario. Taggare per scoprire, non per ordinare. Taggare per scoprire ciò che non abbiamo ancora trovato, non per recuperare una cosa che avevamo visto. Questa è un'altra cosa, e magari ci costruiamo un altro gioco, ma facciamo una cosa per volta. Scoprire per creare gruppi caratterizzati da interessi, problemi o attributi particolari. La fase iniziale del caos è servita per una sorta di cottura iniziale ma non ha evidentemente senso che tutti parlino con tutti, in una comunità che consta di 100-300 persone. Si tratta quindi di far emergere i gruppi. Non è un metodo consolidato. È un esperimento, un esperimento collettivo, che realizzate voi. Non state seguendo istruzioni, state realizzando un esperimento. Con un effetto collaterale rilevante: lo realizzate con la mente, abitando il cybersapazio, creandovi consuetudine, familiarizzando con il luogo."

Internet service providers charging for premium access hold us all to ransom | Technolo... - 0 views

    Cory Doctorow theguardian.com, Monday 28 April 2014 00.00 BST "An ISP should give users the bits they ask for, as quickly as it can, and not deliberately slow down the data The Federal Communications Commission, America's telcoms regulator, has formulated a plan to allow internet service providers (ISPs) to charge companies for the right to "premium" access to its customers. This is the worst internet policy news imaginable. It should strike terror into the heart of anyone who cares about fairness, politics, the widening gap between the rich and the poor, fair trade, entrepreneurship, or innovation. The FCC now stands as the world's foremost symbol for "regulatory capture," and its chairman - a former cable executive lobbyist - is the poster child for an unhealthy relationship between industry and its regulators. What's at stake is "network neutrality," which is the simple principle that your ISP should give you the bits you ask for, as quickly as it can, and not deliberately slow down the data you're looking for. ... "

    Doctorow's intro in his newsletter: "My latest Guardian column, "Internet service providers charging for premium access hold us all to ransom," explains what's at stake now that the FCC is prepared to let ISPs charge services for "premium" access to its subscribers. It's pretty much the worst Internet policy imaginable, an anti-innovation, anti-democratic, anti-justice hand-grenade lobbed by telcos who shout "free market" while they are the beneficiaries of the most extreme industrial government handouts imaginable."

Turning Digital Learning Into Intellectual Property - DML Central 2016 - 0 views

    Monday, January 25, 2016 Ben Williamson "The world's largest publisher of educational textbooks and resources, Pearson, recently extended its work into digital media and learning. As well as producing innovative new digital learning resources and platforms, Pearson is also positioning itself as a major center for the analysis of educational big data. This has implications for how learning is going to be conceptualized in the near future, and begs big questions about how the private ownership of educational data might impact emerging understandings and explanatory theories of the learning process itself."

    Davvero uno strumento potente, questo Esri Story Maps. Carino anche perché ti porta a manipolare un po' di codice con soddisfazione - pare. L'inglese è chiaro, lento e preciso, con numerosi sottotitoli per maggiore chiarezza. Molto rispetto per gli stranieri e i non-esperti di computer. Consigliabile però solo a chi ha molto tempo a disposizione, perché è un po' laborioso.

    variazione sul tema, story map creata (diverse sono le cose ancora da mettere a posto) salvando la mappa come app x web usando il Template/modello predisposto su Esri Story maps "Map Tour" ( o qualcosa di simile) che si presta bene per semplici 'album' di elementi , ognuno col suo tumbnail, da visualizzare interattivamente in una mappa - in questo caso i blog. Il modello, come tutti gli altri si basa sul 1) rieditare - vedi il tutorial già condiviso - le piccole parti di codice specifiche della singola mappa oppure 2) creare la mappa col software, in questo caso ArcGis (simile a Google Maps o Google Maps Engine) e salvarla poi come mappa/app pubblica utilizzando il Template prescelto. http://www.arcgis.com/apps/MapTour/index.html?appid=a87ff4bb8d414ad9a81b5ddbcb244f4d&webmap=e4a4a0e162da49f5bc1ee6510ca33adb
