DART: Open-Domain Structured Data Record to Text Generation

DART is a large and open-domain structured DAta Record to Text generation corpus with high-quality sentence annotations with each input being a set of entity-relation triples following a tree-structured ontology. It consists of 82191 examples across different domains with each input being a semantic RDF triple set derived from data records in tables and the tree ontology of table schema, annotated with sentence description that covers all facts in the triple set.

DART is released in the following paper where you can find more details and baseline results.

Data Content and Format

The DART dataset is available in the data/ directory. The dataset consists of JSON files in data/. Each JSON file contains a list of tripleset-annotation pairs of the form:

  {
    "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."
      }
    ]
  }

We also provide delexicalization dictionaries in data/**/delex/ that map string entities to entity categories.
