Dynamic Semantic Web: Fill & Download for Free

the phrase "dynamic semantic publishing" was probably first coined by the BBC to describe their metadata-driven publishing platformin summary, the novel features of the publishing platform are:a lot of the content is automatically generated based on the metadata stored in the RDF database, i.e. a SPARQL query about a topic will get the relevant aggregated metadata for the web page content (as opposed to manually authored web pages)the underlying domain model is an ontology (as opposed to a relational schema)automated text analysis is used for the journalist authored content (blogs, news articles) so that tags and topics are extracted and stored as metadata for the article in the RDF databasedata from additional datasources is also RDF-ized and stored in the metadata repository (RDF database)inference of new facts derives additional metadata in the RDF database (with respect to the RDF or OWL semantics)the content (journalist authored or dynamically generated) is enriched with external data from the Linked Open Data cloud (DBpedia, Freebase, etc)the BBC used such a dynamic semantic publishing platform for their 2010 World Cup website, and will probably use an enhanced version for the 2012 Olympics.for detailed explanations of the platform you can check out the BBC blogs about the 2010 World Cup [1] and [2] as well as the chapter on "Use of SemanticWeb technologies on the BBC Web Sites" from the book "Linking Enterprise Data" [3]At the European Semantic Technology Conference 2010 I had a presentation about the RDF database used in this particular dynamic semantic publishing platform, you can check it out at [4] (disclaimer: I work for the company developing the database)[1] http://www.bbc.co.uk/blogs/bbcinternet/2010/07/bbc_world_cup_2010_dynamic_sem.html[2] http://www.bbc.co.uk/blogs/bbcinternet/2010/07/the_world_cup_and_a_call_to_ac.html[3] http://www.amazon.com/Linking-Enterprise-Data-David-Wood/dp/1441976647/[4] http://www.slideshare.net/ontotext/ontotext-estc2010showcase

COPE is a goal, but semantic metadata and web as database are the most effective means, and the more granular that metadata is applied at the content component level, the better to be able to dynamically assemble and reassemble content and make it accessible to machines via the web.Google, Yahoo and Bing have formed Schema.org to encourage the spread of semantic metadata. Their goal is to serve up answers to questions from the best sources on the web wherever they are, rather than just search result links to documents.That's consistent with an overall push toward a more granular and structured web. Google bought Metaweb for its Freebase semantically structured dataset, which has since become the basis of its Knowledge Graph. If you structure your content for internal repurposing with the help of Schema.org or W3C semantic web standards, then it will also be suitable for search engine repurposing if made publicly available. Apple Siri, Wolfram|Alpha and Pandora also use semantically-based approaches to serving up content, but their approaches are purely proprietary.One widely respected example of publishing using semantically enriched methods is the BBC's Dynamic Semantic Publishing. See Jem Rayfield's post for details on the method: http://www.bbc.co.uk/blogs/bbcinternet/2012/04/sports_dynamic_semantic.htmlAnother is Elsevier's Smart Content, described this week at SemTechBiz in NYC: http://www.slideshare.net/ayagoda/elsevier-smart-content-ldr-sem-tech-nyc-oct-172012Yet another is Nature Publishing's scientific publishing on the Web. See http://derivadow.com/2012/01/22/scientific-publishing-on-the-web/Other examples are Hearst and the New York Times. See http://open.blogs.nytimes.com/2012/02/16/rnews-is-here-and-this-is-what-it-means/.One of the BBC's DSP pioneers is now at the UK Press Association presumably doing something similar: http://nosql2012.dataversity.net/sessionPop.cfm?confid=70&proposalid=4890The best open data initiatives in government also use these methods, and the University of Southampton is a good place to start to explore standards-based open data activity. See http://data.southampton.ac.uk/Organizations such as The Guardian and NPR use content APIs, which could be considered interim steps toward a full-blown semantic web/web as database approach.It's helpful to understand the basic technologies behind semantically enhanced publishing to be able to learn more from these case studies. We interviewed Tom Scott, now at Nature, while he was at the BBC in 2009, and have a full magazine issue that describes the rationale and basics of Semantic Web methods in use in various industries at http://www.pwc.com/us/en/technology-forecast/spring2009/index.jhtmlFor some basics on how APIs are being used in business, see our API issue at http://www.pwc.com/us/en/technology-forecast/2012/issue2/index.jhtml

see my answer to What is dynamic semantic publishing? for info on how the BBC built a metadata driven website for the 2010 World Cup websitea related question with very goon answers is What are the best examples of the semantic web being used by newspapers, magazines, and TV websites?also check out ThisWeKnow - http://www.thisweknow.org - the website even shows the SPARQL queries that generate the particular web pages, for example [1] is the info page for Palo Alto homeowners, and there is a link at the bottom "Show the query that generated this page" that will show the actual SPARQL for the page[1] http://www.thisweknow.org/l/CA/Palo%20Alto/factoids/13
