Social Science Palooza II. Dismantle Labour's IT to save £8bn, says Tory advisor report - 07/09/2010. Tuesday 07 September 2010 16:11 A think-tank close to the government has proposed dismantling the IT systems and business ecosystem established by Labour's drive to computerise government. Led by Liam Maxwell, the Royal Borough of Windsor and Maidenhead councillor who helped draft the Conservative Technology Policy and other formative Tory IT policy documents, the Network for the Post-Bureaucratic Age said its proposals could cut 40 per cent from the government IT budget of approximately £21bn. The report, "Better for Less - how to make government IT deliver savings", accuses the Labour government of establishing a culture of empire-building that had careered out of control. "Profligate, rudderless, underperforming and ultimately unfair," is how the report summarises the government's IT programme. The suppliers and the government had produced sub-optimal designs using ineffective procurement that unfairly excluded small firms.
Email Alerts. Live Matrix: Home. Categorial Compositionality: A Category Theory Explanation for the Systematicity of Human Cognition. Abstract Classical and Connectionist theories of cognitive architecture seek to explain systematicity (i.e., the property of human cognition whereby cognitive capacity comes in groups of related behaviours) as a consequence of syntactically and functionally compositional representations, respectively. However, both theories depend on ad hoc assumptions to exclude specific instances of these forms of compositionality (e.g. grammars, networks) that do not account for systematicity. By analogy with the Ptolemaic (i.e. geocentric) theory of planetary motion, although either theory can be made to be consistent with the data, both nonetheless fail to fully explain it. Category theory, a branch of mathematics, provides an alternative explanation based on the formal concept of adjunction, which relates a pair of structure-preserving maps, called functors.
A functor generalizes the notion of a map between representational states to include a map between state transformations (or processes). Considering name change: SMW RDF Connector --> SMW RDF IO | Samuel's Project Blog.
Help. Linking things and common sense. Tom Scott’s recent Linking Things post got me jotting down what I’ve been thinking lately about URIs, Linked Data and the Web. First go read Tom’s post if you haven’t already. He does a really nice job of setting the stage for why people care about using distinct URIs (web identifiers) for identifying web documents (aka information resources) and real world things (aka non-information resources). Tom’s opinions are grounded in the experience of really putting these ideas into practice at the BBC. His key point, which he attributes to Michael Smethurst, is that: Some people will tell you that the whole non-information resource thing isn’t necessary – we have a web of documents and we just don’t need to worry about URIs for non-information resources; others will claim that everything is a thing and so every URL is, in effect, a non-information resource.Michael, however, recently made a very good point (as usual): all the interesting assertions are about real world things not documents.
Technology Review: Wikipedia to Add Meaning to Its Pages. As a global resource built from the spare time of millions of volunteers, Wikipedia may be the epitome of Web 2.0. But the Wikimedia Foundation, a nonprofit organization that runs Wikipedia, among other projects, is now thinking about how to make it a linchpin of Web 3.0, or the semantic Web. That means making some of the data on Wikipedia’s 15 million (and counting) articles understandable to computers as well as humans. This would allow software to know, for example, that the numbers shown in one of the columns in this table listing U.S. presidents are dates. That could, in turn, allow applications that draw on Wikipedia to automatically generate historical timelines or answer the kind of general knowledge questions that would usually entail a person finding and reading a relevant entry on the site. “Semantic information already exists in Wikipedia, and people are already building on it,” says Möller.
Publishing Web Data - Sindice. You are now ready to enable your website for effective discovery and synchronization. Your goal is to allow Sindice and other engines to discover what is new or recently changed on your site in an efficient and timely manner. If you have exposed your semantic data by embedding it into your web pages using RDFa or Microformats, or by supporting content negotiation, the best ways to let other systems know about your changes are to provide a sitemap with time indications, or to provide RSS or Atom feeds. See sections 2.1 and 2.2 below. If you have exposed your semantic data by RDF dumps, publish your dataset using the semantic sitemap extension. See section 2.3 below. Also you can send notification of changes directly to Sindice using our PING interface. Whether you publish your semantic content using a standard sitemap, an RSS or Atom feed, or a semantic sitemap, be sure to list the sitemap in your robots.txt file.
