Link individual small graphs with wikidata usig LIMES

For Linking the full WDC dataset, we need to take care about the <RESTRICTION> tag. Since the classes in wikidata are gibberish, eg.:

• Q5: Represents all human beings.
• Q515: Represents cities.
• Q571: Represents books.

etc. These does not make sense to humans, therefore we are interested in their rdfs:label property.

Working pipeline:

Step	Description
Gather Wikidata Classes	Gather all the Wikidata classes with rdfs:label using a SPARQL query
Gather WDC Dataset Classes	Gather all the classes from each WDC dataset
Link Dataset Classes	Link the dataset classes with Wikidata classes
Store Linked Classes	Keep these linked classes for further checking
Automate Config Creation	Automate the creation of config files for LIMES linking based on the KG with only triples

For step Gather Wikidata Classes,

• extract the languages from the classes in WDC dataset.
• Use these language list to extract labels from wikidata using the wikibase service. Query to use:

  SELECT ?class ?classLabel
  WHERE
  {
  SERVICE wikibase:label { bd:serviceParam wikibase:language {list of languages}. }
  {SELECT DISTINCT ?class WHERE {
  ?s wdt:P31 ?class .
  } OFFSET 1000 LIMIT 100}
  }

• Languages for the WDC labels are extracted.

• [ ] Job for getting Wikidata classes for those languages (Running on N1)
