DBin is a Semantic Web application that enables groups of users
with a common interest to cooperatively create semantically
structured knowledge bases. These user groups, which we call
“Semantic Web Communities”, are made possible by creating
customized user environments called “Brainlets”. Brainlets
provide user interfaces and domain specific tools (e.g. querying,
viewing and editing facilities) which enable community
participants to interact with the data of interest. Brainlets are
directly created by domain experts using an XML description
language. DBin clients communicate and exchange annotations
using a P2P infrastructure. Access control and digital signatures
put by DBin inside the authored RDF enable trust and information
filtering. In this paper we show a specific use case where a
“Semantic Web Community” is created to enable a group of users
to share their del.icio.us tags and organize them into a
cooperatively built RDFS ontology.
Ontopoly, a new web-based tool for creating, populating and managing corporate ontologies, will be launched by Ontopia at Online Information 2005. This latest addition to the Ontopia Knowledge Suite significantly lowers the bar for developing and maintain
Freedom is designed to adapt easily to business change and growth. As a result, it can handle and respond to all manner of changes, either in the knowledge or content sources or in the scope of the application domain (which may impact on both ontology str
The term “Semiformal Ontology” refers to a ontology which has a few bits of formality but is largely informal. It is the analog of what Tom Malone calls semi structured data, such as email or office forms. A semiformal ontology could support techn
This piece is based on two talks I gave in the spring of 2005 -- one at the O'Reilly ETech conference in March, entitled "Ontology Is Overrated", and one at the IMCExpo in April entitled "Folksonomies & Tags: The rise of user-developed classification." Th
Ontologies are enabling technology for the Semantic Web. They are a means for people to state what they mean by formal terms used in data that they might generate or consume. Folksonomies are an emergent phenomenon of the social web. They are created a
