Bowlogna. The Bowlogna ontology aims at providing a standard schema for European universities involved in the Bologna Reform of higher-education studies.
The ontology originates from a lexicon defining terms related to the Bologna Reform. In this page you can find the current version of the Bowlogna ontology plus additional links to applications build on top of it.

(LOV) Linked Open Vocabularies. DBpedia.fr. Graph. The core UMBEL ontology now contains about 26,000 reference concepts organized according to 33 super types.
There are more than 60,000 relationships amongst these concepts, resulting in a graph structure of very large size. It is difficult to grasp this graph in the abstract. Thus, using methods earlier described in our use of the Gephi visualization software , we present below a dynamic, navigable rendering of this graph of UMBEL core: Note: at standard resolution, if this graph were to be rendered in actual size, it would be larger than 34 feet by 34 feet square at full zoom !!! Hint: that is about 1200 square feet, or 1/2 the size of a typical American house ! YAGO2 - D5: Databases and Information Systems (Max-Planck-Institut für Informatik)
Overview YAGO is a huge semantic knowledge base, derived from Wikipedia WordNet and GeoNames.
Currently, YAGO has knowledge of more than 10 million entities (like persons, organizations, cities, etc.) and contains more than 120 million facts about these entities. YAGO is special in several ways: The accuracy of YAGO has been manually evaluated, proving a confirmed accuracy of 95%. Every relation is annotated with its confidence value.YAGO combines the clean taxonomy of WordNet with the richness of the Wikipedia category system, assigning the entities to more than 350,000 classes.YAGO is an ontology that is anchored in time and space. YAGO is developed jointly with the DBWeb group at Télécom ParisTech University.
Semantically-Interlinked Online Communities. Freebase. The Friend of a Friend (FOAF) project. Wiki.dbpedia.org : About. DBpedia is a crowd-sourced community effort to extract structured information from Wikipedia and make this information available on the Web.
DBpedia allows you to ask sophisticated queries against Wikipedia, and to link the different data sets on the Web to Wikipedia data. We hope that this work will make it easier for the huge amount of information in Wikipedia to be used in some new interesting ways. Furthermore, it might inspire new mechanisms for navigating, linking, and improving the encyclopedia itself. News DBpedia Version 2014 releasedHi all, we are happy to announce the release of DBpedia 2014.
DBpedia Spotlight V0.7 releasedDBpedia Spotlight is an entity linking tool for connecting free text to DBpedia through the recognition and disambiguation of entities and concepts from the DBpedia KB. The DBpedia Knowledge Base Knowledge bases are playing an increasingly important role in enhancing the intelligence of Web and enterprise search and in supporting information integration.
