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.

Platypus Wiki is an enhanced Wiki Wiki Web with ideas taken from Semantic Web. We call it a Semantic Wiki Wiki Web. It offers a simple user interface to create a Wiki Page plus metadata according with W3C standards. It uses RDF (Resource Description Framework), RDF Schema, and OWL (Web Ontology Language) to create ontologies and manage metadata.

HP Labs home page for semantic web activity. HP have developed the Jenna Sematic Web Toolkit, a java API for manipulating RDF models. Site includes white papers and a list of leading individuals working on Semantic Web related activities.

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.

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.

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).

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.

RDFWeb is an experimental linked information system, where the linked items are machine-understandable documents in the World Wide Web. These documents, written in the XML, RDF and XHTML languages, are harvested by our Web indexing programs, which then merge the resulting information to form one big database. By exploiting various features of the RDF technology alongside related tools such as digital signature, we can use the Web to retrieve structured information that machines can process and act upon. RDFWeb is best understood as an exploration of the question: what would it be like if machines could read what we say in our Web homepages?

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.

Summary of existing resources, articles and references on the OWL Web Ontology Language

SHOE (Simple HTML Ontology Extensions) is an XML-compatible knowledge representation language for the Web. It allows web pages to be described in the context of one or more publicly available ontologies, which provide semantics for reasoning about the contents. This site contains tools for marking up and querying SHOE, sample ontologies, research publications, and a SHOE-based search engine.

The CoMMA project Corporate Memory Management through Agents aims at developing an open, agent based platform for the management of a corporate memory by using the most advanced results on the technical, the content, and the user interaction level.

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

The Web Ontology Working Group is chartered to build upon the RDF Core work a language for defining structured web based ontologies which will provide richer integration and interoperability of data among descriptive communities.

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.

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

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 objective of Esperonto is to form a bridge between the actual Web and the Semantic Web by providing a service to "upgrade" existing content to semantic Web content. Ontologies play a key role in this effort, aiming at unifying, bridging and integrating multiple heterogeneous, international and multilingual digital content.

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

Modulant - The Interoperability Company. Modulant is an enterprise software developer of semantics-based information interoperability solutions.

The objectives are to develop a roadmap for cutting edge research and commercial application of new web technology, specifically to position RTD projects in Framework VI. Semantic Web, Web Services, and their combination may promise a large stream of successful IST projects helping key action III to strengthen its profile of hosting leading research projects with world wide visibility and impact.

This is the community site for Ontoweb, a European Union founded project about Ontology-based information exchange for knowledge management and electronic commerce.

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

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

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
