Nova Spivack's semantic web company Twine is developing a free service to write and host semantic ontologies; the classification trees that enable machines to put concepts in topical context.
May 15, 2009: Berlin. A speech that remixes a bit of David Post's fantastic book, In Search of Jefferson's Moose, given at an event hosted by the Heinrich-Boell-Foundation.
Visualization is a technique to graphically represent sets of data. When data is large or abstract, visualization can help make the data easier to read or understand. There are visualization tools for search, music, networks, online communities, and almost anything else you can think of. Whether you want a desktop application or a web-based tool, there are many specific tools are available on the web that let you visualize all kinds of data. Here are some of the best:
There is too much information available today, from Google to blogs. The death of reading, though, is overblown. The key is media literacy. People should teach media literacy in schools to help.
We believe that dedicating data to the public domain is the best way to ensure that data is universally reusable and remixable. When data is public domain it means that it can be reused automatically without needing to check terms and conditions or track the source of every statement to provide attribution. These kinds of things act as friction to reuse, wasting energy that could be better spent creating inspiring things.
This lecture elaborates on RDF, RDFS, and SOAP starting from a short recap of XML, and the history of the W3C and the development of "open standard recommendations". We also compare RDF triples with DOGMA lexons. We finalise by listing shortcomings of RDFS regarding semantics, and give short overview of the history of OWL as one answer to this. A full elaboration on OWL and description logic is for another lecture.
In practice, it is assumed that most URNs will refer to on-line resources, and that a mechanism will exist which takes a URN and returns a list of URLs[20]. Another, intriguing, possibility is that URNs may be linked to other URNs rather than directly to URLs. This raises the prospect of their being used to establish a semantic network of pointers to resources - a true virtual library!
* Google has access to WorldCat metadata
* Google says bad metadata comes from external providers
* No restrictions on which WorldCat metadata fields can be used
