### Dataset Summary

SciDTB is a domain-specific discourse treebank annotated on scientific articles written in English-language. Different from widely-used RST-DT and PDTB, SciDTB uses dependency trees to represent discourse structure, which is flexible and simplified to some extent but do not sacrifice structural integrity. Furthermore, this treebank is made as a benchmark for evaluating discourse dependency parsers. This dataset can benefit many downstream NLP tasks such as machine translation and automatic summarization. 

### Supported Tasks and Leaderboards

### Languages

English.

## Dataset Structure

### Data Instances

A typical data point consist of `root` which is a list of nodes in dependency tree. Each node in the list has four fields: `id` containing id for the node, `parent` contains id of the parent node, `text` refers to the span that is part of the current node and finally `relation` represents relation between current node and parent node.

An example from SciDTB train set is given below:  

```
{
	"root": [
		{
			"id": 0,
			"parent": -1,
			"text": "ROOT",
			"relation": "null"
		},
		{
			"id": 1,
			"parent": 0,
			"text": "We propose a neural network approach ",
			"relation": "ROOT"
		},
		{
			"id": 2,
			"parent": 1,
			"text": "to benefit from the non-linearity of corpus-wide statistics for part-of-speech ( POS ) tagging . <S>",
			"relation": "enablement"
		},
		{
			"id": 3,
			"parent": 1,
			"text": "We investigated several types of corpus-wide information for the words , such as word embeddings and POS tag distributions . <S>",
			"relation": "elab-aspect"
		},
		{
			"id": 4,
			"parent": 5,
			"text": "Since these statistics are encoded as dense continuous features , ",
			"relation": "cause"
		},
		{
			"id": 5,
			"parent": 3,
			"text": "it is not trivial to combine these features ",
			"relation": "elab-addition"
		},
		{
			"id": 6,
			"parent": 5,
			"text": "comparing with sparse discrete features . <S>",
			"relation": "comparison"
		},
		{
			"id": 7,
			"parent": 1,
			"text": "Our tagger is designed as a combination of a linear model for discrete features and a feed-forward neural network ",
			"relation": "elab-aspect"
		},
		{
			"id": 8,
			"parent": 7,
			"text": "that captures the non-linear interactions among the continuous features . <S>",
			"relation": "elab-addition"
		},
		{
			"id": 9,
			"parent": 10,
			"text": "By using several recent advances in the activation functions for neural networks , ",
			"relation": "manner-means"
		},
		{
			"id": 10,
			"parent": 1,
			"text": "the proposed method marks new state-of-the-art accuracies for English POS tagging tasks . <S>",
			"relation": "evaluation"
		}
	]
}
```

### Data Fields

- id: an integer identifier for the node
- parent: an integer identifier for the parent node
- text: a string containing text for the current node
- relation: a string representing discourse relation between current node and parent node

### Data Splits

Dataset consists of three splits: `train`, `dev` and  `test`.  

| Train   | Valid | Test |
| ------ | ----- | ---- |
| 743 |  154 | 152|
