+### Link to Main Data Card
+
+You can find the main data card on the [GEM Website](https://gem-benchmark.com/data_cards/dart).
+
+### Dataset Summary 
+
+DART is an English dataset aggregating multiple other data-to-text dataset in a common triple-based format. The new format is completely flat, thus not requiring a model to learn hierarchical structures, while still retaining the full information. 
+
+You can load the dataset via:
+```
+import datasets
+data = datasets.load_dataset('GEM/dart')
+```
+The data loader can be found [here](https://huggingface.co/datasets/GEM/dart).

Data-to-text annotations can be a costly process, especially when dealing with tables which are the major source of structured data and contain nontrivial structures. To this end, we propose a procedure of extracting semantic triples from tables that encodes their structures by exploiting the semantic dependencies among table headers and the table title. Our dataset construction framework effectively merged heterogeneous sources from open domain semantic parsing and spoken dialogue systems by utilizing techniques including tree ontology annotation, question-answer pair to declarative sentence conversion, and predicate unification, all with minimum post-editing. We present systematic evaluation on DART as well as new state-of-the-art results on WebNLG 2017 to show that DART (1) poses new challenges to existing data-to-text datasets and (2) facilitates out-of-domain generalization. Our data and code can be found at https://github.com/Yale-LILY/dart.",

+### Dataset Structure
+
+#### Data Fields
+
+<!-- info: List and describe the fields present in the dataset. -->
+<!-- scope: telescope -->
+-`tripleset`: a list of tuples, each tuple has 3 items
+-`subtree_was_extended`: a boolean variable (true or false)
+-`annotations`: a list of dict, each with source and text keys.
+-`source`: a string mentioning the name of the source table.
+-`text`: a sentence string.
+
+
+#### Reason for Structure
+
+<!-- info: How was the dataset structure determined? -->
+<!-- scope: microscope -->
+The structure is supposed to be able more complex structures beyond "flat" attribute-value pairs, instead encoding hierarchical relationships.
+
+#### How were labels chosen?
+
+<!-- info: How were the labels chosen? -->
+<!-- scope: microscope -->
+They are a combination of those from existing datasets and new annotations that take advantage of the hierarchical structure
+
+#### Example Instance
+
+<!-- info: Provide a JSON formatted example of a typical instance in the dataset. -->
+<!-- scope: periscope -->
+```
+ {
+    "tripleset": [
+      [
+        "Ben Mauk",
+        "High school",
+        "Kenton"
+      ],
+      [
+        "Ben Mauk",
+        "College",
+        "Wake Forest Cincinnati"
+      ]
+    ],
+    "subtree_was_extended": false,
+    "annotations": [
+      {
+        "source": "WikiTableQuestions_lily",
+        "text": "Ben Mauk, who attended Kenton High School, attended Wake Forest Cincinnati for college."
+      }
+    ]
+  }
+```
+
+#### Data Splits
+
+<!-- info: Describe and name the splits in the dataset if there are more than one. -->
+<!-- scope: periscope -->
+|Input Unit | Examples | Vocab Size | Words per SR | Sents per SR | Tables |
+| ------------- | ------------- || ------------- || ------------- || ------------- || ------------- |
+|Triple Set | 82,191 | 33.2K | 21.6 | 1.5 | 5,623 |
+
+| Train | Dev | Test|
+| ------------- | ------------- || ------------- |
+| 62,659 | 6,980 | 12,552|
+
+
+Statistics of DART decomposed by different collection methods. DART exhibits a great deal of topical variety in terms of the number of unique predicates, the number of unique triples, and the vocabulary size. These statistics are computed from DART v1.1.1; the number of unique predicates reported is post-unification (see Section 3.4). SR: Surface Realization.
+([details in Table 1 and 2](https://arxiv.org/pdf/2007.02871.pdf)).
+
+
+#### Splitting Criteria
+
+<!-- info: Describe any criteria for splitting the data, if used. If there are differences between the splits (e.g., if the training annotations are machine-generated and the dev and test ones are created by humans, or if different numbers of annotators contributed to each example), describe them here. -->
+<!-- scope: microscope -->
+For WebNLG 2017 and Cleaned E2E,  DART use the original data splits. For the new annotation on WikiTableQuestions and WikiSQL, random splitting will make train, dev, and test splits contain similar tables and similar <triple-set, sentence> examples. They are thus split based on Jaccard similarity such that no training examples has a similarity with a test example of over 0.5

+<!-- scope: telescope -->
+`Offline media collection`
+
+#### Creation Process
+
+<!-- info: If created for the dataset, describe the creation process. -->
+<!-- scope: microscope -->
+Creators proposed a two-stage annotation process for constructing triple set sentence pairs based on a tree-structured ontology of each table. First, internal skilled annotators denote the parent column for each column header. Then, a larger number of annotators provide a sentential description of an automatically-chosen subset of table cells in a row. To form a triple set sentence pair, the highlighted cells can be converted to a connected triple set automatically according to the column ontology for the given table.

+
+#### Technical Limitations
+
+<!-- info: Describe any known technical limitations, such as spurrious correlations, train/test overlap, annotation biases, or mis-annotations, and cite the works that first identified these limitations when possible. -->
+<!-- scope: microscope -->
+The dataset may contain some social biases, as the input sentences are based on Wikipedia (WikiTableQuestions, WikiSQL, WebNLG). Studies have shown that the English Wikipedia contains gender biases([Dinan et al., 2020](https://www.aclweb.org/anthology/2020.emnlp-main.23.pdf)), racial biases([Papakyriakopoulos et al., 2020 (https://dl.acm.org/doi/pdf/10.1145/3351095.3372843)) and geographical bias([Livingstone et al., 2010](https://doi.org/10.5204/mcj.315)). [More info](https://en.wikipedia.org/wiki/Racial_bias_on_Wikipedia#cite_note-23).
+
+
+#### Unsuited Applications
+
+<!-- info: When using a model trained on this dataset in a setting where users or the public may interact with its predictions, what are some pitfalls to look out for? In particular, describe some applications of the general task featured in this dataset that its curation or properties make it less suitable for. -->
+<!-- scope: microscope -->
+The end-to-end transformer has the lowest performance since the transformer model needs intermediate pipeline planning steps to have higher performance. Similar findings can be found in [Castro Ferreira et al., 2019](https://arxiv.org/pdf/1908.09022.pdf).
