"The Suggested Upper Merged Ontology (SUMO) and its domain ontologies form the largest formal public ontology in existence today. They are being used for research and applications in search, linguistics and reasoning. SUMO is the only formal ontology that has been mapped to all of the WordNet lexicon. SUMO is written in the SUO-KIF language. SUMO is free and owned by the IEEE. The ontologies that extend SUMO are available under GNU General Public License. Adam Pease is the Technical Editor of SUMO."

"iServe is what we refer to as service warehouse which unifies service publication, analysis, and discovery through the use of lightweight semantics as well as advanced discovery and analytic capabilities. iServe provides the typical features of service registries and additional functionality that exploits service descriptions, service annotations and further data gathered and derived from the analysis of these descriptions, data crawled from the Web, periodic monitoring and user activities."

DiscOU is a resources discovery engine relying on a semantic index of Open University Open Content. It semantically analyses the content of an online resource, and matches it by similarity to other existing Open University content to retrieve the most relevant pieces. It currently works with BBC programme pages, as demonstrated in the video below, as well as from text entered/pasted in the DiscOU alfa interface.

"Apache Stanbol provides a set of reusable components for semantic content management. Apache Stanbol's intended use is to extend traditional content management systems with semantic services. Other feasible use cases include: direct usage from web applications (e.g. for tag extraction/suggestion; or text completion in search fields), 'smart' content workflows or email routing based on extracted entities, topics, etc."

BabelNet is both a multilingual encyclopedic dictionary, with lexicographic and encyclopedic coverage of terms, and a semantic network which connects concepts and named entities in a very large network of semantic relations, made up of more than 9 million entries, called Babel synsets. Each Babel synset represents a given meaning and contains all the synonyms which express that meaning in a range of different languages.

The Web Science Trust (WST) is a charitable body with the aim of supporting the global development of Web Science  through a network of world class laboratories known as WSTnet . It is hosted by the University of Southampton. The origins of the Web Science Trust can be found in the Web Science Research Initiative (WSRI) which was established in 2006.
