CrossRE is a new, freely-available crossdomain benchmark for RE, which comprises six distinct text domains and includes 
multilabel annotations. It includes the following domains: news, politics, natural science, music, literature and 
artificial intelligence. The semantic relations are annotated on top of CrossNER (Liu et al., 2021), a cross-domain
dataset for NER which contains domain-specific entity types.
The dataset contains 17 relation labels for the six domains: PART-OF, PHYSICAL, USAGE, ROLE, SOCIAL, 
GENERAL-AFFILIATION, COMPARE, TEMPORAL, ARTIFACT, ORIGIN, TOPIC, OPPOSITE, CAUSE-EFFECT, WIN-DEFEAT, TYPEOF, NAMED, and 
RELATED-TO.

- **Paper:** [CrossRE: A Cross-Domain Dataset for Relation Extraction](https://arxiv.org/abs/2210.09345)

### Dataset Summary
CrossRE is a new, freely-available crossdomain benchmark for RE, which comprises six distinct text domains and includes 
multilabel annotations. It includes the following domains: news, politics, natural science, music, literature and 
artificial intelligence. The semantic relations are annotated on top of CrossNER (Liu et al., 2021), a cross-domain
dataset for NER which contains domain-specific entity types.
The dataset contains 17 relation labels for the six domains: PART-OF, PHYSICAL, USAGE, ROLE, SOCIAL, 
GENERAL-AFFILIATION, COMPARE, TEMPORAL, ARTIFACT, ORIGIN, TOPIC, OPPOSITE, CAUSE-EFFECT, WIN-DEFEAT, TYPEOF, NAMED, and 
RELATED-TO.

### Data Fields

The data fields are the same among all splits.
- `doc_key`: the instance id of this sentence, a `string` feature.
- `sentence`: the list of tokens of this sentence, obtained with spaCy, a `list` of `string` features.
- `ner`: the list of named entities in this sentence, a `list` of `dict` features.
  - `id-start`: the start index of the entity, a `int` feature.
  - `id-end`: the end index of the entity, a `int` feature.
  - `entity-type`: the type of the entity, a `string` feature.
- `relations`: the list of relations in this sentence, a `list` of `dict` features.
  - `id_1-start`: the start index of the first entity, a `int` feature.
  - `id_1-end`: the end index of the first entity, a `int` feature.
  - `id_2-start`: the start index of the second entity, a `int` feature.
  - `id_2-end`: the end index of the second entity, a `int` feature.
  - `relation-type`: the type of the relation, a `string` feature.
  - `Exp`: the explanation of the relation type assigned, a `string` feature.
  - `Un`: uncertainty of the annotator, a `bool` feature.
  - `SA`: existence of syntax ambiguity which poses a challenge for the annotator, a `bool` feature.
