Description:
The MOMIS (Mediator envirOnment for Multiple Information Sources) is a framework to perform information extraction and integration from both structured and semi-structured data sources, plus query management facilities to take incoming queries and process them through the exploitation of the annotated Global Schema, GVV. The framework consists of a language and several semi-automatic tools.
The MOMIS system is based on a conventional wrapper/mediator architecture, and provides methods and open tools for data management in Internet-based information systems by using a CORBA-2 interface.

Description:
Bibster is a Peer-to-Peer system for exchanging bibliographic data among researchers, obtained e.g. from Bibtex files. Bibster exploits ontologies in data representation, query formulation, query-routing and answer presentation. Bibster is a fully implemented open source solution built on top of the JXTA platform. The system is currently being used by several hundreds of users from multiple organizations across the world.

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.

Description:
Semantic Portal on International Affairs: A web-portal architecture for a political institute, where the online content can be accessed by navigating through categories or by a keyword-based, full text search engine. The access is based on the meaning of concepts and relations of the International Affairs domain. The approach comprises an automatic ontology-based annotator, a semantic search engine with a natural language interface, a web publication tool allowing semantic navigation, and a 3D visualization component.

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.

Description:
MuseumFinland provides the end-user with a semantic seamless view to distributed heterogeneous cultural collections. A view-based semantic search engine based on seven cultural ontologies can be used for getting overviews of the contents along nine different dimensions (such as artifact type, material, place of usage, time of creation, situation of usage etc.), and for concept-based information retrieval. Semantic browsing is supported by a logic-based link generator that associates collection pages with each other in a meaning way and with explanatory link labels. For the museums, MuseumFinland provides a shared national publication channel for the Semantic Web.

Description:
The Madiera Portal provides access to an unprecedented quantity of social sciences quantitative datasets using an easy to use Yahoo-style interface. It works by harvesting statistical datasets published on the Semantic Web.
The Madiera Portal provides unified access to the resources (social sciences quantitative studies and variable groups) published by the data archives that take part to the Madiera project, a 5th Framework EU-project.
The resources are categorised using a set of multi and monolingual thesauri and classifications, currently:
GCL (UK Government Category List), CESSDA (Council of European Social Science Data Archives Classification) and ELSST (European Language Social Science Thesaurus).

Description:
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.

I've spent the last few weeks working on the programme and papers for the SWAD-Europe Semantic Web Storage and Retrieval Workshop being held from 2003-11-13 - 14 in Amsterdam, Netherlands next week. I just updated the web site with the list of attendees and position papers which includes a position paper by me: Redland RDF Storage and Retrieval
