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
A great jump towards the advent of the Semantic Web will take place when a critical mass of web resources is available for use in a semantic way. This goal can be reached by the creation of semantic meta-data in the publication workflow, or by the develop
Category search within digital repositories is poorly supported. This means that people wishing to access the assets of digital repositories are largely limited to keyword search, which means they must know what they want in order to look for it. Our part
The introduction of semantics on the web will lead to a new generation of services based on content rather than on syntax. |:| Effective semantic search engines will provide means for successful searches avoiding the heavy burden experimented by users in
Automatic semantic annotation of information content is an open problem, but is crucial to the realization of the Semantic Web. Annotation systems require the initial definition of an ontology and as well as a knowledge base. Both of these resources work
We believe that the enterprise ontology will become a cornerstone in many information systems in the future. In general terms, an ontology is an organization of a body of knowledge or, at least, an organization of a set of terms related to a body of know
Part of the allure of classifying things by assigning tags to them is that the user can give free reign to sloppiness. There is no authority —human or computational— passing judgment on the appropriateness or validity of tags, because tags have to mak
The goal of this ontology is to model the relationship between an agent, an arbitrary resource, and one or more tags. This relationship is embodied in one or more taggings, which are temporal events associating the actors.
Ontologies play a prominent role on the Semantic Web. They make possible the widespread publication of machine understandable data, opening myriad opportunities for automated information processing. However, because of the Semantic Web's distributed natur
This post is part contribution to the general Web 3.0 / Data-Web / Semantic Web discourse, and part experiment / demonstration of the Data Web. I came across a pretty deep comments trail about the aforementioned items on Fred Wilson's blog (aptly title
Ontology-based information exchange for knowledge management and electronic commerce via Semantic Web technologies and languages. This is the community site for Ontoweb, a European Union founded project about Ontology-based information exchange for knowle
Web Ontology Language (OWL) is a markup language for publishing and sharing data using ontologies on the Internet. OWL is a vocabulary extension of the Resource Description Framework (RDF) and is derived from the DAML+OIL Web Ontology Language (see also D
A Semantic Wiki is a Wiki enhanced with technologies developed by the Semantic Web community in order to encode more knowledge than just structured text and hyperlinks. Usually this extra knowledge is available in a formal language, so that machines can (
The emergence of P2P Inference Engines and domain-specific ontologies in Web 3.0 (aka Semantic Web) will present a major threat to the central “search” engine model. In Web 3.0 (aka Semantic Web) P2P Inference Engines running on millions of users’ P
“The Semantic Web is a project that intends to create a universal medium for information exchange by putting documents with computer-processable meaning (semantics) on the World Wide Web.” "Google's very broad take on Web 3.0...enables you to use you
Machines (or machine-based reasoning, aka 'AI software' or ‘info agents’) would then be able to use those laboriously –but not entirely manually– constructed ontologies to build a view (or formal model) of how the individual terms within the infor

Information vs Knowledge To a machine, knowledge is comprehended information (aka new information produced through the application of deductive reasoning to exiting information). To a machine, information is only data, until it is processed and compr
Real life data needs are never semantically pure. Users need to browse their data in different ways. Hierarchies are too hard to reorganize on a whim. Stuff I need access to DOES NOT HAPPEN TO EQUAL the stuff at the top of the tree: Hierarchies are bad a
I’m a bit of a Saussurean about this, in that I think that taxonomy (or ontology, depending upon your disciplinary point of origin) is crystallised/calcified folksonomy....Crystallised and calcified...one has connotations of order, beauty, and value; th
Swoogle is a search engine for the Semantic Web on the Web. Swoogle crawl the World Wide Web for a special class of web documents called Semantic Web documents, which are written in RDF. Currently, Swoogle only indexes some metadata about Semantic Web doc
