Description:
Magpie (available as an IE or Mozilla plugin) works as a streamlined toolbar that sits within your web browser and automatically highlights key items of interest (concepts linked to an underlying ontology) within any web page you visit. For each highlighted term it provides a set of related 'services' e.g. explanations, examples, further links. Magpie's architecture, which is open to ontologies and semantic web services, provides a software framework for
designing and implementing semantic web applications.

Description:
The aim of COHSE (Conceptual Open Hypermedia Services Environment) was to research into methods to improve significantly the quality, consistency and breadth of linking of WWW documents at retrieval time (as readers browse the documents) and authoring time (as authors create the documents). It uses three leading-edge technologies:
an ontological reasoning service which is used to represent a sophisticated conceptual model of document terms and their relationships; a Web-based open hypermedia link service that can offer a range of different link-providing facilities in a scalable and non-intrusive fashion and the integration of the ontology service and the open hypermedia link service to form a conceptual hypermedia system to enable documents to be linked via metadata describing their contents.
GOHSE is a demonstration of the COHSE infrastructure to bioinformatics. COHSE brings together an ontology
and an open hypermedia service to dynamically add links to web resources. In this example, the Gene
Ontology is used as the ontology, with resources from the GO annotation database as link targets.

Description:
Annotea is a W3C LEAD (Live Early Adoption and Demonstration) project under Semantic Web Advanced Development (SWAD). Annotea enhances collaboration via shared metadata based Web annotations, bookmarks, and their combinations. By annotations we mean comments, notes, explanations, or other types of external remarks that can be attached to any Web document or a selected part of the document without actually needing to touch the document. When the user gets the document he or she can also load the annotations attached to it from a selected annotation server or several servers and see what his peer group thinks. Similarly shared bookmarks can be attached to Web documents to help organize them under different topics, to easily find them later, to help find related material and to collaboratively filter bookmarked material.

Description:
The Semantic Web Assistant explores the possibilities of a combination of Semantic Web technologies with production rule systems for letting end-users discover some of the powerful applications of the SemanticWeb on their desktop and was developed as a prototype on top of the Jena Semantic Web Framework.
The Semantic Web Assistant combines the data on the Semantic Web with the capabilities of forward chaining production rule systems. It lets the user define simple if-then rules that operate on RDF data obtained from the Web. RDF Schema and OWL Ontologies can be used to deduce additional data. Conclusions of rules include actions that are carried out when a rule instance fires. The Semantic Web Assistant includes some predefined actions, eg. e-mail notification, downloading of web resources and execution of arbitrary system commands. Adding additional actions should be easy.
Possible applications of the Semantic Web Assistant include the monitoring of news sites or weblogs using the RSS 1.0 RDF vocabulary. Given the generic nature of the rule mechanisms applications are only limited by the availability of RDF data and the user's imagination.

Description:
Platypus Wiki is a project to develop an enhanced Wiki Web with ideas borrowed from the Semantic Web. It offers a simple user interface to create wiki pages with metadata based on W3C standards. It uses RDF (Resource Description Framework), RDF Schema and OWL (Web Ontology Language) to create ontologies and manage metadata. Platypus Wiki is an ongoing open source project started on 23th December 2003. The project is actually hosted on SourceForge and licensed under GNU GPL. Platypus Wiki is a rapid and useful Personal Knowledge Management system, as well as a valuable tool to manage Communities of Practice.

Description:
The SECO system harvests RDF files from the Web and consolidates the different data sets into a coherent representation aligned along an internal schema. SECO provides interfaces for humans to browse and for software agents to query the data repository.
SECO is a system to enable collaboration in online communities. It collects RDF data from the web, stores it in an index, and makes it accessible via a web interface. As of late 2003 the system contained information about more than 7000 people and 2000 news items. This data has been created by a large number of people. The challenge is to tidy up this data and integrate it in a way that facilitates easy access and re-use.

Description:
CS AKTiveSpace is a semantic web explorer for investigating the Computer
Science research domain in the United Kingdom. It combines information
from multiple heterogeneous sources, such as published RDF sources,
personal web pages, and data bases in order to provide an integrated view
of this multidimensional space.
