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.

Academic Institution Internal Structure Ontology (AIISO)

(LOV) Linked Open Vocabularies. 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 [1], 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 ! This UMBEL graph displays: You may also want to inspect a static version of this big graph by downloading a PDF.

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.

YAGO2 - D5: Databases and Information Systems (Max-Planck-Institut für Informatik)

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.
