SNAPP is a software tool that allows users to visualize the network of interactions resulting from discussion forum posts and replies. The network visualisations of forum interactions provide an opportunity for teachers to rapidly identify patterns of user behaviour – at any stage of course progression. SNAPP has been developed to extract all user interactions from various commercial and open source learning management systems (LMS) such as BlackBoard (including the former WebCT), and Moodle. SNAPP is compatible for both Mac and PC users and operates in Internet Explorer, Firefox and Safari.

Die Datenschutzrisiken seien bei den Sicherheitsbehörden "gravierend", insbesondere bei den Nachrichtendiensten, da diese auch Informationen zu legalem Verhalten und Erkenntnisse mit noch unklarer Relevanz sammeln dürfen. Eine systemweite Suche könnte auch für Unverdächtige möglicherweise schwere Konsequenzen haben.

20 years ago, Tim Berners-Lee invented the World Wide Web. For his next project, he`s building a web for open, linked data that could do for numbers what the Web did for words, pictures, video: unlock our data and reframe the way we use it together.

Thumbnail image for Cirrus_clouds2.jpgIn our last post on data journalism, we ran across a number of tools that would be helpful for anyone who is interested in how to make sense of data. The tools represent a renaissance in how we make sense of our information culture. They provide context and meaning to the often baffling world of big data. This is a snapshot of what is available. We are relying on the work done by Paul Bradshaw, whose blog is an excellent source about the new world of data journalism.
ZBW Labs eröffnen Ihnen einen Blick in unsere Werkstatt. Wir stellen hier in der ZBW entwickelte innovative Anwendungen und Services vor, die noch keinen Eingang in den Regelbetrieb gefunden haben, sondern als Prototypen und Beta-Versionen laufend erweitert und verbessert werden. Sie setzen auf neuesten Technologien auf und tragen zum Teil noch experimentellen Charakter.
Auf der internationalen Konferenz iPres haben Experten die Zukunft der Archivierung digitaler Daten diskutiert. Dabei spielen nur ökologische Aspekte, sondern auch analoge Datenträger Den Radiobeitrag zu diesem Artikel hören Sie am Sonntag, dem 26. September 2010, um 22.30 Uhr im Ö1-Netzkulturmagazin "matrix". Herausforderungen für die digitale Langzeitarchivierung Steintafeln haben eine Lebensdauer von mehreren Tausend Jahren. Bücher und Handschriften aus säurefreiem Papier halten bei guter Lagerung einige Hundert Jahre. Optische Speichermedien wie CD und DVD bringen es noch auf 50 bis 100 Jahre, während Festplatten maximal zehn Jahre durchhalten. Archivare und Kuratoren zerbrechen sich deshalb schon seit Jahren darüber den Kopf, wie sie ihre digitalen Archive fit für eine lange Zukunft machen können. Die ständig wachsende Datenmenge und die rasante technische Entwicklung, die immer neue Speichermedien und Datenformate hervorbringt, stellen sie dabei vor große Herausforderungen.

At TED2009, Tim Berners-Lee called for "raw data now" -- for governments, scientists and institutions to make their data openly available on the web. At TED University in 2010, he shows a few of the interesting results when the data gets linked up. About Tim Berners-Lee Tim Berners-Lee invented the World Wide Web.

Data Mining, Analytics, and Databases
Databases are the workhorse of the enterprise today. Searching through databases and finding useful information has become a big computational challenge. Researchers from academia and Microsoft, Oracle, SAP, and many other corporations are looking to CUDA-enabled GPUs to find a scalable solution.
