Eingehender Vergleich der BM-Tools, Fokus auf akademsichen Nutzern. "In many ways these new tools resemble blogs stripped down to the bare essentials. Here the essential unit of information is a link, not a story"
"we have to (...) merge and leverage emerging and traditional tools to improve findability. (...) at the intersection of those two models is a more powerful framework for identifying, sharing, and finding information. The goal is a metadata ecology"
"Tagging in and of its self is a helpful step up from no tagging, but is no where near as beneficial as opening the tagging to all. Folksonomy tagging can provide connections across cultures and disciplines (...)"
"Tagging works because it strikes a balance between the individual and social. It serves the individual motive of remembering, and forms a ad-hoc social groups around it."
"a blog dedicated to folksonomies and reflections on the social tagging paradigm (...) I'm currently an LIS postgraduate, studying and working in London, UK. (...) Nick Woolley" - With bibliography on folksonomies!
"This study surveyed the folksonomy as a complex network. The result indicates that the network, which is composed of the tags from the folksonomy, displays both properties of small world and scale-free."
"controlled vocabularies often miss out on input from content authors and become rigid (...); folksonomies will begin to break down for the reasons mentioned above. Treating them as major parts of a single metada ecology might expose a useful symbiosis"
"Despite its intrinsic anarchist nature, the dynamics of this terminology system spontaneously leads to patterns of terminology common to the whole community or to subgroups of it."
"They are built to be human-usable (...) are targeted primarily for storage/retrieval of personal information and serendipitous discovery of group information . (...) The development communities for each are abuzz with ideas for exploiting the structure"
"social networking services that really work are the ones that are built around objects. (...) Flickr, for example, has turned photos into objects of sociality. On del.icio.us the objects are the URLs. EVDB, Upcoming.org, and evnt focus on events as objec
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:
Google Wave is the kind of open-source online collaboration tool that should drive scientists to wire their research and publications into an interactive data web, says Cameron Neylon.
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.
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.
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
It has been a couple of years since I posted statistics from WorldCat, so here is a new spreadsheet based on an October 1, 2009 snapshot (see the earlier post for an explanation of the table). WorldCat has changed dramatically...
* Alternative to OCLC cataloging already in some libraries
* Fewer records, emphasis on quality
* Copy cataloging record search and notification included
