Image Annotation on the Semantic Web

Image Annotation on the Semantic Web: "Many applications that involve multimedia content make use of some form of metadata that describe this content. The goals of this document are (i) to explain what the advantages are of using Semantic Web languages and technologies for the creation, storage, manipulation, interchange and processing of image metadata, and (ii) to provide guidelines for doing so. The document gives a number of use cases that illustrate ways to exploit Semantic Web technologies for image annotation, an overview of RDF and OWL vocabularies developed for this task and an overview of relevant tools."

Searching and Ranking Ontologies on the Semantic Web

Searching and Ranking Ontologies on the Semantic Web: "The number of ontologies available online is increasing constantly. Tools that are capable of searching, retrieving, and ranking ontologies are becoming crucial to facilitate ontology search and reuse. In this document, we describe OntoSearch, which is a tool for capturing and searching ontologies on the Semantic web. We also briefly describe AKTiveRank which is used to rank OWL ontologies based on certain ontology-structure analysis."

Freedom and Restraint: Tags, Vocabularies and Ontologies

Freedom and Restraint: Tags, Vocabularies and Ontologies: "The benefit of metadata is widely recognized. However, the nature of that information and the method of production remains a topic of some debate. This division is most noticeable between those who believe in ’free tagging’, and those who prefer the more formal construction of an ontology to define both the vocabulary of the domain and the relationships between the concepts within it. Looking at the community surrounding online amateur authors and the descriptive metadata they have developed over the last thirty years we consider what we can learn from a mature but amateur tagging community. This paper considers how these two systems might be used together to add the easy usability of free tagging to ontology descriptions and the conceptual richness of ontologies to free tags."

Caboodle Launches Open Source Semantic Web-Based Search Engine

LinuxElectrons - Caboodle Networks Launches Open Source Semantic Web-Based Search Engine: "BURLINGAME, Calif.: Caboodle Networks has launched an open source search engine based upon semantic web standards. This new search engine, Kit, (available for free at http://semantical.org) is ideal for finding digital content and services otherwise poorly suited to discovery by traditional text-retrieval search engines the company claims. Kit can intelligently recommend related digital content such as games, music, images, and video, thereby truly leveraging the value hidden in the “long tail” of published content. Now companies and individuals hosting Internet gaming and music sites, as well as companies such as wireless carriers with mobile portals, have access to the very best standards-based solution for locating and recommending their downloadable content and services."
