Ontologies put into action
Thinking about the Semantic Web
Ontology Online
A semantic web experiment with a focus on Ontology Visualisation and Querying.For an idea of what we are about:
- Check out jOWL, a javascript library for traversing OWL-RDFS documents (under development).
- Try out the Ontology Interface below
- See the Ajax/FreeBase-enabled semantic web demo on wine.
Ontology Interface
An online listing of existing ontologies, taxonomies, folksonomies etc...
Molecular functions, biological processes and cellular components.
All about cells.
An example of an ontology annotated with URL's

Technology
Semantic Web Application
A java web application, running on TomCat. The Motor Behind this website. A Search Engine and Interface to stored ontologies. Currently over 25.000 Concepts are Browseable.
Makes use of: Java Server Faces, XMLPullParser, ...
Ontology Mashup
AJAX/Javascript functionality pulls relevant data about concepts in from a mix of websites. The concept widgets:
- Books: Matching Book Results as defined by google.
- Images: Matching Image Results as defined by google.
- Blog entries: Matching Blog Entries as defined by BlogLines.
- Digg stories: Matching Digg news items as defined by Digg.com
- Featured Site: A site that provides encyclopedic information about the concept (not always defined - Cfr. Tree of Life for frequent examples).
- Instance data: In development, a widget that requests instance data about a given class from FreeBase. For a preview: the widget under development
Makes use of: jQuery, Sarissa, Google Ajax API's.
Ontologies
Custom created ontologies, as well as some OBO Foundry Ontologies, see the Ontology Interface above or browse all available Namespaces. The ontologies are converted into a relational database format (MySQL database) which allows more flexibility in retrieving connections (bidirectional access to horizontal and vertical relations in the ontology).
