What is Semantic Similarity? Definition of Semantic Similarity: A concept whereby a set of documents or terms within term lists are assigned a metric based on the likeness of their meaning/semantic content. ( Wikipedia, 2012e ).
Ontologies tend to be found everywhere. They are viewed as the silver bullet for many applications, such as database integration, peer-to-peer systems, e-commerce, semantic web services, or social networks. However, in open or evolving systems, such as the semantic web, different parties would, in
OpenCyc is the open source version of the Cyc technology, the world's largest and most complete general knowledge base and commonsense reasoning engine. OpenCyc can be used as the basis of a wide variety of intelligent applications such as:
* rapid development of an ontology in a vertical area
* email prioritizing, routing, summarization, and annotating
* expert systems
* games
to name just a few.
Model, organize and leverage content and knowledge. Manage reference schemas, taxonomies, thesaurus and ontology. Classify content. Power vertical search portals
Agile Knowledge Engineering and Semantic Web (AKSW)
The Research Group Agile Knowledge Engineering and Semantic Web (AKSW) is hosted by the Department for Business-oriented Information Systems (BIS) of the Institute of Computer Science (IfI) / University of Leipzig.
Goals
* Development of methods for Agile Knowledge Engineering inside the research field of the Semantic Web
* Implementation of tools and applications for Agile Knowledge Engineering
* Research of the underlying Semantic Web Technologies
* Development of fundamental Semantic Web tools and applications
AKSW is committed to the open source and open access movements.
Knoodl is sort of an ontology editor, registry/repository, and wiki all rolled into an easy to use online application. There's never been anything quite like it.
* Upload an ontology you already have, or build one from scratch.
* Add rich documentation with wikitext, so that other people can understand what your ontology is about.
* Work with other people on the same vocabulary, at the same time
* Find and download other ontologies and use them in semantic applications.
OntoSelect monitors the web to provide an access point for ontologies on any possible topic or domain that is automatically updated, organized in a meaningful way and with support for ontology search and selection. Selected ontologies may be used for ins
Source vs. Resource Ontology The notion of a resource is fundamental in current networked information systems. The term "resource" is used often, specifically in relation the World Wide Web and the W3C's semantic web activity, in standards such as Resour
