Description
NeMig are two English and German knowledge graphs constructed from news articles on the topic of migration, collected from online media outlets from Germany and the US, respectively. NeMIg contains rich textual and metadata information, sub-topics and sentiment annotations, as well as named entities extracted from the articles' content and metadata and linked to Wikidata. The graphs are expanded with up to two-hop neighbors from Wikidata of the initial set of linked entities.
NeMig comes in four flavors, for both the German, and the English corpora:
- Base NeMig: contains literals and entities from the corresponding annotated news corpus;
- Entities NeMig: derived from the Base NeMIg by removing all literal nodes, it contains only resource nodes;
- Enriched Entities NeMig: derived from the Entities NeMig by enriching it with up to two-hop neighbors from Wikidata, it contains only resource nodes and Wikidata triples;
- Complete NeMig: the combination of the Base and Enriched Entities NeMig, it contains both literals and resources.
