Piggy Bank can collect “pure” information in the following cases: The web page has invisible link(s) to RDF data (encoded in RDF/XML or RDF/N3 formats). One of Piggy Bank's "screen scrapers" matches the current URL. A screen scraper is small Javasc
The Resource Description Framework (RDF) is a W3C standard for describing Web resources, such as the title, author, modification date, content, and copyright information of a Web page. What is RDF? RDF stands for Resource Description Framework RDF is
Discusses three conceptual components of the semantic web project (1. expressing meaning, 2. knowledge representation, and 3. ontologies), with "educated layperson's" technical details on semantic markup, software agents, and machine-readable content serv
There has been a lot of hype about the Semantic Web, and this has not been a good thing. Spurious claims about what the Semantic Web might and might not be able to do have been choking public understanding of it, and adding to the confusion that many peop
This guide contains links to many RDF resources including examples, documents, software, tools and projects that use RDF, a standard for describing resources on the web.
This column, the third in a series, shows how to add semantic knowledge to an RDF application by incorporating WordNet synonym sets. With the added knowledge of the WordNet lexical database, you can search a set of RDF data for related concepts, not just
FOAFCorp: Corporate Friends of Friends What is this? RDF is a great data format for describing interconnected entities. With FOAF, we have a simple fun vocabulary for describing social networks, people, organisations etc. The FOAFCorp experiment extends
RDFWeb is intended to be both fun and technically challenging. We hope that at least some of the writing here will be accessible for a general audience, although much of it will be for the rather small community familiar with the subtleties of various Sem
Semantic Interoperability of Metadata and Information in unLike Environments. SIMILE is focused on developing robust, open source tools based on Semantic Web technologies that improve access, management and reuse among digital assets. SIMILE is a joint p
Annotea is a W3C Semantic Web Advanced Development project that provides a framework for rich communication about Web pages through shared RDF metadata. An RDF model of bookmark classification permits multiple classification systems to be related to each
The motivation is to enable the common and consistent description of persons (using the existing semantics of vCard) and to encode these in RDF/XML. RDF is an application of the Extensible Markup Language XML.
In this column, Uche Ogbuji completes his introduction to XML and semantics, setting the stage for the more practical columns that will follow. Thinking XML addresses knowledge management aspects of XML, including metadata, semantics, Resource Description
Abstract from downloadable PDF: Data on the Semantic Web is semi-structured and does not follow one fixed schema. Faceted browsing is a natural technique for navigating such data, partitioning the information space into orthogonal conceptual dimensions.
The world of the semantic web, as based on RDF, is really simple at the base. This article shows you how to get started. It uses a simplified teaching language -- Notation 3 or N3 -- which is basically equivalent to RDF in its XML syntax, but easier to sc
FOAF facilitates the creation of the Semantic Web equivalent of the archetypal personal homepage: My name is Leigh, this is a picture of me, I'm interested in XML, and here are some links to my friends. And just like the HTML version, FOAF documents can b
DBin is general purpose Semantic Web application that enables power users (domain experts) to create "discussion groups" where users annotate any subject of interest (from "beers" as in our example to anything really). At low level, these annotatins are e
