Graph Schema Computation

An ontology (vocabulary) consists of terms and classes, describing how some data should be represented. However, such pre-defined vocabularies are generally loosely followed. Instead, a graph schema is a "vocabulary" that is generated from the data itself. Therefore, what it provides a more realistic description of what is actually there in the data.
An interesting aspect of a graph schema is that it is a RDF graph. It can then be queried in parallel of another application, e.g., in SPARQLed for providing suggestions on the predicates or classes.
The computation of the graph schema with this implementation consists in executing SPARQL queries. It is adapted then for small datasets.
