Dataset Card for GEM

Dataset Summary

GEM is a benchmark environment for Natural Language Generation with a focus on its Evaluation, both through human annotations and automated Metrics.

GEM aims to:

• measure NLG progress across 13 datasets spanning many NLG tasks and languages.
• provide an in-depth analysis of data and models presented via data statements and challenge sets.
• develop standards for evaluation of generated text using both automated and human metrics.

It is our goal to regularly update GEM and to encourage toward more inclusive practices in dataset development by extending existing data or developing datasets for additional languages.

You can find more complete information in the dataset cards for each of the subsets:

• CommonGen
• Czech Restaurant
• DART
• E2E
• MLSum
• Schema-Guided Dialog
• WebNLG
• Wiki-Auto/ASSET/TURK
• WikiLingua
• XSum

The subsets are organized by task:

{
    "summarization": {
        "mlsum": ["mlsum_de", "mlsum_es"],
        "wiki_lingua": ["wiki_lingua_es_en", "wiki_lingua_ru_en", "wiki_lingua_tr_en", "wiki_lingua_vi_en"],
        "xsum": ["xsum"],
    },
    "struct2text": {
        "common_gen": ["common_gen"],
        "cs_restaurants": ["cs_restaurants"],
        "dart": ["dart"],

    },
    "dialog": {
        "schema_guided_dialog": ["schema_guided_dialog"],
    },
}

Each example has one target per example in its training set, and a set of references (with one or more items) in its validation and test set.
