Upload datasets to FREME triplestore

[jnehring]

Upload the datasets we need for the rdfs:label feature (#92) to our FREME triplestore. Only triples with rdfs:label property should be uploaded to FREME NER.

I think first we need the english DBPedia. We still need to consider whether more datasets are required.

@bgrusdt please create the dataset first

• Download the dbpedia english dump.
• Write a script that extracts all triples with english labels. Labels can be expressed via rdfs:label but also via other properties, e.g. foaf:name or skos:prefLabel. Please create a list of label properties.
• The dataset can contain many labels for one resource but we need only one label.

I have uploaded the DBpedia labels (english only) to our FREME triplestore. The labels dataset is loaded in the http://www.freme-project.eu/datasets/dbpedia-labels graph
