An excellent one page overview of the Semantic Web. An ideal visual starting point which explains succinctly and in simple to understand language the key concepts of the Semantic Web

The Karlsruhe Ontology (KAON) tool suite builds on RDF and provides specialized tools including: SDK, engineering, discovery, management and presentation of ontologies and metadata. Site includes middleware downloads, whitepapers, specifications and demonstrations. A practical web resource for Semantic web development.

An Intelligent Brokering Service for Knowledge-Component Reuse on the World-Wide Web. The objective of IBROW is to develop intelligent brokers that are able to distributively configure reusable components into knowledge systems through the World-Wide Web. The WWW is changing the nature of software development to a distributive plug & play process, which requires a new kind of managing software: intelligent software brokers. IBROW will integrate research on heterogeneous DB, interoperability and Web technology with knowledge-system technology and ontologies.

The Portable Information Access (PIA) project aims to develop a domain adaptable information extraction (IE) system for annotating semantic content in texts. IE systems basically aim to extract proto-typical facts from large collections of texts such as the activations between proteins in molecular biology or the merging and acquisitions of companies in business news. In contrast to other Web-based technologies such as information retrieval (IR) which are characterized by strong portability, no such system as yet exists for IE.

Unicorn has developed a comprehensive architecture for the next generation of data infrastructure. Unicorn enables the enterprise to leverage the value of disparate information assets in a unified information model.

SMORE is a tool that allows users to markup their documents in RDF using web ontologies in association with user-specific terms and elements.

Home page for the W3C Semantic Web project. Starting point for information, articles and the summary of W3C projects and activities.

iMorph is a technology provider specializing in the transformation of information for dynamic web implementation.

ILRT's Semantic Web Research Group works in the area of making the information on the web more usable for machines, especially using technologies such as RDF. A useful summary of research projects, standards works and demonstrations in the area of Semantic Web

Web-IQ.com is a software research and development company specializing in Semantic Web Services.

The Darwin Information Typing Architecture (DITA) is an XML-based, end-to-end architecture for authoring, producing, and delivering technical information. This architecture consists of a set of design principles for creating "information-typed" modules at a topic level and for using that content in delivery modes such as online help and product support portals on the Web.

In accord with Tim Berners-Lee's vision of a Semantic Web as "an extension of the current one, in which information is given well-defined meaning, better enabling computers and people to work in cooperation", the OntoWeb Network has been set up to provide support for, disseminate information on, and encourage development of, ontologies as the essential technology for the Semantic Web.

Contivo is the only company with a platform independent, model-based semantic server for designing and managing data integration. Contivo automates the design of data transformation between applications through model reuse and collaboration

KTweb brings together the European projects and people working in information access and knowledge technologies - in research, academia and business - and offers information and resources in these domains at a global level. An good starting point for knowledge technologies information.

FEF supports the conceptual model proposed in Financial Exchange Theory. Financial Exchange Theory provides a basis for the definition of financial entities such as international financial products, financial transactions, financial services and monitoring positions. Financial components, relating to generic functions within international financial markets, are put together following a simple set of rules to create all the above financial entities. FEF is defined as classes, relationships and constraints; actual international financial market entities are recorded as instances. The structure and nature of all financial entities can thus be seen and compared. FEF was created using Stanford University's ontology defining tool, "Protege 2000". FEF is an initiative by International Financial Information Publishing Ltd (Ifip) and has been created based upon the proprietary ‘I-Format’ data model marketed by Ifip for enterprise-wide publication of financial transaction processing data (www.financial-format.com). FEF only contains those components and attributes required to describe Financial Exchange Theory. Initially only a limited number of financial entities will be defined within FEF. FEF is available free of charge.

Semantic Web community portal with news, information and demonstrations of the evolving concepts and technology.

OpenCyc is the open source version of the Cyc technology, the worlds largest and most complete general knowledge base and commonsense reasonging engine. Cycorp, the builders of Cyc, have set up an independent organization, OpenCyc.org, to disseminate and administer OpenCyc, and have committed to a pipeline through which all current and future Cyc technology will flow into ResearchCyc (available for R&D in academia and industry) and then OpenCyc.

Protégé-2000 is an integrated ontology and knowledge-base editing environment. It provides an open-source, extensible architecture for the creation of customized knowledge-based tools in Java. Protégé-2000 is available as free software under the open-source Mozilla Public License.

OilEd is a simple ontology editor which allows the user to build ontologies using OIL. The intention behind OilEd is to provide a simple, freeware editor that demonstrates the use of, and stimulates interest in, OIL. OilEd is not intended as a full ontology development environment. The OilEd executable is available as freeware.

OWL is a semantic markup language for publishing and sharing ontologies on the World Wide Web. OWL is derived from the DAML+OIL Web Ontology Language [DAML+OIL] and builds upon the Resource Description Framework

This multidisciplinary project aims at offering methodological and software support (i.e. models, methods and tools) for knowledge management (i.e., for building, managing and distributing a corporate memory).

Semantic World is a web community dedicated to the use of semantic information management methods in industry. Semantic World contains relevant news and analysis, a comprehensive resource center, and interactive forums for practitioners of semantic methodologies to share experiences, problems, and initiatives. Semantic World aims to support and influence developing standards for ontology modeling, semantic mapping, and the use of semantic information management methods in IT.

Home page of the DARPA Agenet Markup Language and related technologies. The DAML language is being developed as an extension to XML and the Resource Description Framework (RDF). The latest release of the language (DAML+OIL) provides a rich set of constructs with which to create ontologies and to markup information so that it is machine readable and understandable.

RDQL is an implementation of an SQL-like query language for RDF. It treats RDF as data and provides query with triple patterns and constraints over a single RDF model. Part of the HP Labs Semantic Web resources.

Through our website, whitepapers, and consulting services, Semaview aims to be the world leader of semantic technologies.
