Recent developments in KR include the concept of the Semantic Web, and development of XML-based knowledge representation languages and standards, including Resource Description Framework ( RDF ), RDF Schema, Topic Maps, DARPA Agent Markup Language ( DAML ), Ontology Inference Layer ( OIL ), and Web Ontology Language ( OWL ).

Development of the Semantic Web, has included development of XML-based knowledge representation languages and standards, including RDF, RDF Schema, Topic Maps, DARPA Agent Markup Language ( DAML ), Ontology Inference Layer ( OIL ), and Web Ontology Language ( OWL ).

DAML + OIL had its roots in three main languages-DAML, as described above, OIL ( Ontology Inference Layer ) and SHOE, an earlier US research project.

OIL ( Ontology Inference Layer or Ontology Interchange Language ) can be regarded as an ontology infrastructure for the Semantic Web.

OIL stands for Ontology Inference Layer or Ontology Interchange Language.

Many XML-based applications now exist, including Resource Description Framework ( RDF ), XForms, DocBook, SOAP and the Web Ontology Language ( OWL ).

Significant progress has also been made in bringing the world of UML modeling and the Semantic Web together through the adoption of the Ontology Definition Metamodel which relates UML models in a standard way with RDF and Web Ontology Language ( OWL ) models.

It involves publishing in languages specifically designed for data: Resource Description Framework ( RDF ), Web Ontology Language ( OWL ), and Extensible Markup Language ( XML ).

Many of the techniques mentioned here will require extensions to the Web Ontology Language ( OWL ) for example to annotate conditional probabilities.

* Web Ontology Language ( OWL ), a family of knowledge representation languages

* Web Ontology Language

* Submission request to the World Wide Web Consortium: DAML + OIL Web Ontology Language

One of the most recent is the Web Ontology Language ( OWL ) ( but ontologies are a very specialized kind of metadata, and OWL has no built-in support for most of the information represented in UML ).

* Web Ontology Language

Much of the work in OIL was subsequently incorporated into DAML + OIL and the Web Ontology Language ( OWL ).

* Towards a Reference Terminology for Ontology Research and Development

The Suggested Upper Merged Ontology or SUMO is an upper ontology intended as a foundation ontology for a variety of computer information processing systems.

The Web Ontology Language ( OWL ) is a family of knowledge representation languages for authoring ontologies.

The natural acronym for Web Ontology Language would be WOL instead of OWL.

* DOLCE: Descriptive Ontology for Linguistic and Cognitive Engineering

* The Four-Category Ontology: A Metaphysical Foundation for Natural Science ( Oxford: Oxford University Press, 2006 )

* Probabilistic Ontology Model, a method for ontology learning, see KAON

IDEF5, or Integrated Definition for Ontology Description Capture Method, is a software engineering method to develop and maintain usable, accurate, domain ontologies.

* Web Ontology Language ( although the official acronym is OWL ), a markup language for publishing and sharing data using ontologies on the World Wide Web

Investigators at IGS work on Disease Ontology research, the Data Analysis and Coordination Center ( DACC ) for HMP, and other grants.

* An Ontology editor for the KM language: KMgen.

The National Center for Biomedical Ontology ( www. bioontology. org ) develops tools for automated annotation of database records based on the textual descriptions of those records.

Using a synonym Ontology created from WordNet Kuropka shows good results for document similarity.

In Semantic Web languages, such as Resource Description Framework ( RDF ) and Web Ontology Language ( OWL ), a statement is a binary relation.

WebOnt is the W3C's Semantic Web Activity Working group on Web Ontology Language.

Work in the W3C toward the Semantic Web is currently focused by publications related to the Resource Description Framework ( RDF ), Gleaning Resource Descriptions from Dialects of Languages ( GRDDL ) and Web Ontology Language ( OWL ).

Semantic similarity measures have been applied and developed in biomedical ontologies, namely, the Gene Ontology ( GO ).

A Context-aware Semantic Similarity Model for Ontology Environments.

At the turn of the century he became active in the Semantic Web community, contributing substantially ( perhaps solely ) to the revised semantics of RDF known as RDF-Core, one of the three designers ( along with Peter Patel-Schneider and Ian Horrocks ) of the Web Ontology Language semantics, and most recently contributed to SPARQL.
