The NeOn Project (briefly)The NeOn Project (briefly)
Enabling applications exploiting the Semantic Web at large – Dynamically retrieving the relevant semantic resources – Combining several, heterogeneous Ontologies
Challenges:– heterogeneity, large-scale semantics, metadata and ontology dynamics, distributed development, etc.
Key Outcomes:– the NeOn toolkit, a complete environment for ontology lifecycle management
– reference architecture for semantic applications
– methodological guidelines
– community building
– 3 case studies in 2 domains

The NeOn ToolkitThe NeOn Toolkit
Reference implementation of the NeOn architecture– Support ontology engineering and management – Support for complete ontology lifecycle– Support for different languages (OWL, F-Logic)– Support for networked ontologies (modules, mappings)
Built on the Eclipse platform
Extensible architecture– Via Eclipse plugin
mechanism – Via Web Services

OysterOyster
The NeON ontology registry system
Allows ontology designer to share ontologies by describing their metadata and….
… distribute them over a peer-to-peer network

WatsonWatson
Watson is a Gateway to the Semantic Web
It collects (through web crawling), analyses, indexes and gives access to semantic information and ontologies on the Web
At first sight: a search engine for the Semantic Web
But focuses on providing high level services and APIs for application development

And Also…And Also…
The Alignment server– Store and manage ontology alignments
online – Retrieve and manipulate alignments– Evaluate alignments– Produce alignments with an extensible set
of mathcing techniques– Based on the alignment API
TS-ORS– An Open Rating System for Ontologies– Allow users to review different properties of
ontologies (e.g. reusability, coverage, etc.)– Allow users to express trust and distrust
statements on reviews– Provide customized ontology ranking
mechanisms based on collaborative evaluations

Building a community of ontology Building a community of ontology developersdevelopers
Nice developments and interfaces are not enough– How do we encourage people to share their ontologies through
our systems?– How do we attract users to retrieve and reuse ontologies from our
systems?– How do we obtain feedbacks from the community, obtain reviews
and quality information on ontologies, encourage discussions within the community on ontology design, application reuse?
Elements of solution?– Provide infrastructure services to facilitate the exploitation of
ontologies?– Provide Web 2.0 like features (reviews, forums, tagging,
comments, etc.)– ?
