RDF Book Mashup
The RDF book mashup demonstrates how Web 2.0 data sources like Amazon, Google or Yahoo can be integrated into the Semantic Web. The RDF book mashup makes information about books, their authors, reviews, and online bookstores available on the Semantic Web. This information can be used by RDF tools and you can link to it from your own Semantic Web data. Contents News 2009/07/17: GoodRelations support added.Computational semantics
Computational semantics is the study of how to automate the process of constructing and reasoning with meaning representations of natural language expressions. It consequently plays an important role in natural language processing and computational linguistics .
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.
