## Dataset Description
- **Repository:** [knowledge-net](https://github.com/diffbot/knowledge-net)
- **Paper:** [KnowledgeNet: A Benchmark Dataset for Knowledge Base Population](https://aclanthology.org/D19-1069/)
- **Size of downloaded dataset files:** 12.59 MB
- **Size of the generated dataset:** 6.1 MB
### Dataset Summary
KnowledgeNet is a benchmark dataset for the task of automatically populating a knowledge base (Wikidata) with facts 
expressed in natural language text on the web. KnowledgeNet provides text exhaustively annotated with facts, thus 
enabling the holistic end-to-end evaluation of knowledge base population systems as a whole, unlike previous benchmarks 
that are more suitable for the evaluation of individual subcomponents (e.g., entity linking, relation extraction).

For instance, the dataset contains text expressing the fact (Gennaro Basile; RESIDENCE; Moravia), in the passage: 
"Gennaro Basile was an Italian painter, born in Naples but active in the German-speaking countries. He settled at Brünn, 
in Moravia, and lived about 1756..."

For a description of the dataset and baseline systems, please refer to their 
[EMNLP paper](https://github.com/diffbot/knowledge-net/blob/master/knowledgenet-emnlp-cameraready.pdf).

Note: This Datasetreader currently only supports the `train` split and does not contain negative examples.
In addition to the original format this repository also provides two version (`knet_re`, `knet_tokenized`) that are 
easier to use for simple relation extraction. You can load them with 
`datasets.load_dataset("DFKI-SLT/knowledge_net", name="<config>")`.

### Supported Tasks and Leaderboards
