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.

Flink is a crossover between a social experiment and a semantic application. It brings together a number of different knowledge sources and use them to learn about the social structures of the community that created them - in this case, the community of Semantic Web researchers. The resulting application is a Who is Who of the Semantic Web, which can be of interest to this community as a reflection of their social organization, but is also valuable as an input for Social Network Analysis, a branch of sociology concerned with relational data. Export to popular network analysis packages is directly supported by the application.

Swoogle is a crawler-based indexing and retrieval system for the Semantic Web documents - i.e., RDF or OWL documents. It analyzes the documents it discovered to compute useful metadata properties and relationships between them. The documents are also indexed by using an information retrieval system which can use either character N-Gram or URIs as terms to finnd documents matching a user's query or to compute the similarity among a set of documents. One of the interesting properties computed for each Semantic Web document is its rank - a measure of the document's importance on the Semantic Web.

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:
Unspecified Ontologies for P2P:
this approach premises that the domain ontology of an E-commerce application is not fully defined and parts of it can be dynamically specified by the peers. To implement semantic routing we extend a hypercube graph structure to a multi-layered hypercube (MLH), where each vertex recursively consists of another hypercube. We use hashing to deal with the unspecified nature of the ontology and with the variety of terms that can be used. This allows the peers to distributively manage a dynamically growing ontology and uniformly distributes the ads among the MLH. To eliminate ambiguity and enhance system precision, the terms used by the peers in the ontological description of an object undergo simple semantic standardization using WordNet.

The World Wide is becoming the mainsource for music, both in terms of digital music directly accessible over the web and portals like Amazon that sell music in more traditional formats. The World Wide Web is becoming the main source for music, both in terms of digital music directly accessible over the web and portals like Amazon that sell music in more traditional formats. As in other areas the size of the Web and the amount of available information is becoming a problem, because browsing through all available files is not an option.
The aim of this application is to help people to find albums and to actively recommend albums that the user is likely to enjoy. In MusiDB the functionality of finding a piece of music based on its name and the name of the artists is achieved by matching the user input with Musicbrainz, one of largest RDF data bases, that contains information about artists, albums and songs. Based on the information about the albums of that particular artist, the Amazon Web service is queried to provide additional information about albums containing the song (this can be more than one due to compilations and best-of albums) like the cover, sound samples, the retails price etc.

Knowledge Management Platform (KmP)
A Semantic Web Service for the Cartography of Competences in the Telecom Valley of Sophia Antipolis
This Web application relies on ontology-based models and inferences and merges the frameworks of the semantic web (RDF, RDFS) and the classic web (HTML, CSS, SVG) and the structured web (XML, XSLT) to integrate data coming from very different sources, allow queries from different viewpoints, adapt content to users, analyze, group, infer and render indicators of the Telecom Valley situation. KMP relies on the integration of multiple components: databases for back-end persistence, web servers with JSP and servlets to provide front ends, and the CORESE semantic web server [1]to provide semantic web processing capabilities.
[1] http://www-sop.inria.fr/acacia/soft/corese/
Usecase:
The aim of the KmP project is to increase the portfolio of competences of the Telecom Valley of Sophia Antipolis by helping actors in expressing their interests and needs in a common space. The solution relies on the specification, design, building and evaluation of an online customizable semantic web application.
Provide a Map of Competences to Foster Partnerships:
The primary objective of this project is to create and implement an innovative knowledge management solution based on:
a repository shared by the members of the Telecom Valley, including a map of competencies, actors and projects
a common language to describe and differentiate the needs and the resources of all the participants.
The elaboration of the repository is articulated around three application scenarios:
Acquire and give a broader visibility of the Telecom Valley community
Search and exchange information in the case of Inter-firm cooperation
Search and exchange information in the case of Public research / Private research cooperation
Thus, the goal of KMP is to build an innovative solution of knowledge management shared within a community, in order to foster synergies and partnerships by providing a dynamic map of the competences of the different stakeholders. The solution relies on the specification, design, building and evaluation of an online customizable service.

The goal of the BioPAX group is to develop a common exchange format for biological pathways data.
The BioPAX project began at the Fourth BioPathways Consortium Meeting, a satellite of the ISMB'02 Conference held in Edmonton, Canada in August 2002. There it was decided that the creation of a standard data exchanage format for pathway information was not only a good first step toward building an open source pathway information resource, but also that such an exchange format would be a desirable end in itself as it would facilitate sharing of pathways information between existing databases, both public and private.

Description:
Urchin is a customizable RSS aggregator and filter written in Perl. It consists of two main parts: a web-based user interface to query its database and an administration unit that allows the control for managing channels in the database. Administrators can add RSS 0.9*, 1.0, and 2.0 channels to the Urchin, where items are converted into RDF and stored in its native mySQL database. Using the web interface, user can query the database using Urchin-specific keywords, plaintext, or the RCQL query language. Urchin can then display the results as several output formats, including RSS 1.0 and RSS 0.91 feeds. This aggregation allows each user to create a RSS feed tailored to the individual's interest from the available channels in the database. In addition, Urchin is suitable for building a RSS portal service.
The Urchin-Kowari project replaces the mySQL database with the specialized RDF triple store Kowari. This takes advantage of the fact that all data in Urchin are RDF statements and Kowari is a specialized RDF database. Urchin and Kowari communicate via SOAP, and can be running on different machines. This decoupling of interface and storage allows users the freedom to access any available Kowari server on the Web. In Urchin-Kowari, the core Urchin functionalities are preserved as much as possible. The Web interface retains its look, but query syntax has been modified. Raw iTQL queries to the storage replace the RCQL queries. Many Urchin keywords are being developed. Administrative control of the channels is also preserved.
The current implementation is written using Urchin 0.90 and Kowari 1.0.5

A personal publishing system with semantic web techniques. Publishing activity consists of not only content producing but also information gathering. In the current web environment, we perform these activities respectively for lack of glue. We adopt content aggregation and syndication methods with RSS: RDF Site Summary, which is a basic element of semantic web, to this problem. One of the key issues of semantic web is how metadata can be generated. We use Weblog tools for personal RSS generator. The user only describes her/his content in a fixed form so that the tool will create RSS-based metadata automatically.

Description:
Creative Commons has developed a Web application that helps people dedicate their creative works to the public domain or retain their copyright while licensing them as free for certain uses, on certain conditions. Creative Commons are designed for a variety of creative works: websites, scholarship, music, film, photography, literature, courseware, etc. To this end, they have developed metadata that can be used to associate creative works with their public domain or license status in a machine-readable way. These metadata enable applications to find, for example, photographs that are free to use provided that the original photographer is credited, or songs that may be copied, distributed, or sampled with no restrictions whatsoever. They provide an RDF Schema (http://creativecommons.org/technology/metadata/implement) with two major parts: a work description, and a license description. The work description uses Dublin Core properties to provide information about the work. Finally they provide online tools to generates the metadata describing your resources (http://creativecommons.org/license/)
Usecase:
"Too often the debate over creative control tends to the extremes. At one pole is a vision of total control - a world in which every last use of a work is regulated and in which 'all rights reserved' (and then some) is the norm. At the other end is a vision of anarchy - a world in which creators enjoy a wide range of freedom but are left vulnerable to exploitation. Balance, compromise, and moderation - once the driving forces of a copyright system that valued innovation and protection equally - have become endangered species. Creative Commons is working to revive them. We use private rights to create public goods: creative works set free for certain uses. Like the free software and open-source movements, our ends are cooperative and community-minded, but our means are voluntary and libertarian. We work to offer creators a best-of-both-worlds way to protect their works while encouraging certain uses of them - to declare 'some rights reserved.' "

catalogs using concepts and relationships of the Earth science realm.
At present, AnnoTerra processes newsfeeds from the NASA Earth Observatory
by extracting meaningful keywords. These keywords are then used to
perform ontology based semantic searches in the Global Change Master
Directory (GCMD) for relevant resources. The results retrieved are
subsequently mapped to an ontology of the Earth Observing System (EOS)
ClearingHOuse (ECHO) and a new search is performed for corresponding
datasets in the ECHO catalog. By creating an ontology for the GCMD and
ECHO, and a equivalence between the two, we've created a semantic
unification of Earth science resources registered in GCMD and data
collections registered in ECHO.
The project name, AnnoTerra, is derived from Annotated Terrestrial
