Knowledge representation (KR) is an area of artificial intelligence research aimed at representing knowledge in symbols to facilitate inferencing from those knowledge elements, creating new elements of knowledge. The KR can be made to be independent of the underlying knowledge model or knowledge base system (KBS) such as a semantic network . [ 1 ] [ edit ] Overview

The CO-ODE project aims to build authoring tools and infrastructure that make ontology engineering easier. We specifically support the development and use of OWL-DL ontologies, by being heavily involved in the creation of infrastructure and plugins for the Protégé platform and more recently, OWL2.0 support for the OWL API . Many of our collaborators have come from the life sciences community, but we aim to support as broad a range of users as possible - researchers, librarians, industry, and the Semantic Web community 17th June 2008: Protégé 4.0 is now officially released . Protégé 4.0 is now built on top of the OWL API , providing more flexible development and a straightforward migration path for OWL-based applications.

Ontology is Overrated -- Categories, Links, and Tags
Ontology is Overrated: Categories, Links, and Tags 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." The written version is a heavily edited concatenation of those two talks.

WordNet - Princeton University Cognitive Science Laboratory
WordNet® is a large lexical database of English. Nouns, verbs, adjectives and adverbs are grouped into sets of cognitive synonyms (synsets), each expressing a distinct concept. Synsets are interlinked by means of conceptual-semantic and lexical relations. The resulting network of meaningfully related words and concepts can be navigated with the browser . WordNet is also freely and publicly available for download . WordNet's structure makes it a useful tool for computational linguistics and natural language processing.
Kurt Gödel is best known to mathematicians and the general public for his celebrated incompleteness theorems.
Kurt G?'s Ontological Argument
SchemaWeb is a directory of RDF schemas expressed in the RDFS, OWL and DAML+OIL schema languages. SchemaWeb is a place for developers and designers working with RDF. It provides a comprehensive directory of RDF schemas to be browsed and searched by human agents and also an extensive set of web services to be used by software agents that wish to obtain real-time schema information whilst processing RDF data. RDF Schemas are the critical layer of the Semantic Web. They provide the semantic linkage that 'intelligent' software needs to extract value giving information from the raw data defined by RDF triples. the schemas held in the SchemaWeb directory and inspect the details of individual schemas including classes and properties, the raw RDF/XML and the RDF triples.
